Date of Trouble: June 2005
Indication: Received call from homeowner on Valley View Drive of very low water pressure.
Resolution: With no other reports of problems in GT and knowing that Valley View is supplied by tank P located at the end of Promentory West I decided my first check would be at that tank. I opened the tank and it was empty. I checked the circuit breaker near the manhole which supplies this tank and found it was tripped. Reset the breaker and the tank began to fill. No explanation of why the breaker tripped, possible lightning or power surge. Breaker held and trouble did not reoccur.

Date of Trouble: April 3, 2006 at 5:30 am
Indication: Low level alarm from tank H received by Roy Gertson and relayed to Walt Lafford at 8:30am
Trouble isolation process: Went to station A to check tank H level on the monitor panel. Showed tank A level at 15 feet which is impossible since tank is only 10 feet deep. Proceeded to tank H and measured current on transducer, reading 24ma with about 3.5 feet in tank. Should have read about 7-8ma. Replaced transducer and returned to station A to verify trouble was resolved.
Resolution: Replaced defective pressure transducer at tank H.

Date of Trouble: April 17, 2006 at 2:30 pm
Indication: While programming at Station A, we noticed so water flowing from well A, though indications where that water should be flowing.
Trouble isolation process: Checked main circuit breaker to well A. It seemed OK. Checked breaker at motor control. The breaker seemed to not reset. Checked voltage in and out of breaker. Input was OK. Output was not.
Resolution: Breaker needs to be replaced. Contractor will replace it.

Date of Trouble: 4/23/06
Indication: Resident reported water coming from a manhole cover on Aspen Turn.
Resolution: Found water leaking from a previously frozen air relief valve. Notified Steve Miles who pumped out the manhole and shut off the valve. Valve will be replaced as soon as possible.

Date of Trouble: May 09, 2006
Indication: Received call from resident on Mountainside Drive saying they had been experiencing low water pressure and now had no water at all.
Resolution: Went to station A to check tank levels. Tank B which feeds Mountainside was down to 0.2 feet. Tank A had about 3.5 feet and tank D was full. Thought maybe Miles Construction was using too much water for the road work. Went home and called Steve Miles and he said no water had been used since last week.
At this point wondered why tank A was not filling faster with all wells running. With the help of Chip went to check out station D and found both transfer pumps were air locked. (running but not moving any water) Think this happened last week when they used all the water out of tank D for the roads and when the tank was empty it siphoned the water out of the pumps. So even though the transfer pumps would not run until the tank level came up they were already air locked when the tank came back up. Chip opened the plug at the top of the pumps and they both began pumping again.
Set timers at stations A and D to manual override and on until next day to give all tanks chance to refill. The A transfer pump at station D is now leaking probably caused by running dry. Requested Mac Dey to repair the pump and left it turned off. Also discussed with Steve Miles not using water from this tank anymore for road work. I think a similar problem happened last year also. This why we put the low level pump cutoff in the tank, but this didn't prevent the siphon action on the pump.

Date of Trouble: 6/2/06
Indication: Water in the road at the intersection of Elkhorn Way and Princeton Hills phoned in by homeowner .
Resolution: Investigated and contacted Miles Construction for repair of water main. Problem occurred at an underground valve location. Think it was caused by heavy construction traffic running over the valve cover causing the plastic pipe to split. Pipe was repaired the next day by Miles Construction.
Walt Lafford 6/2/2006 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 6/16/06
Indication: Water level indicator for tank C reading above tank.
Resolution: Tank C was overflowing and pump was on. We removed the low voltage sensors and replaced badly calcified probes and cleaned the others. This should be regular maintenance.
Ed Butler 6/16/2006 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: August 2006
Indication: While checking station A noted loud noise coming from transfer pump B. Shut pump off and called Dey Electric for repair.
Resolution: Dey Electric rebuilt pump and restored to service.
Walt Lafford 8/1/2006 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 12/7/06
Indication: Low temperature alarm at station C.
Resolution: Found that the portable heater was not working. Reset GFI (ground fault interrupter) in the wall outlet and heater returned to normal operation. Rechecked the following day and unit was still OK.
Walt Lafford 12/7/2006 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 1/11/07
Indication: Looks like the transducer at well C has gone haywire or the critters have chewed thru the cable. It was showing about 13 feet but was also making wild swings in level.
Resolution: Replaced transducer
Walt Lafford 1/11/2007 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 3/15/07
Indication: Home owner called about free water on Aspen Turn. Also noticed monitor showed a steep decline in water level in tank H. Found a water line which had frozen and broke in water man hole on Aspen Turn.
Resolution: Repaired broken line

Date of Trouble: 8/15/07
Indication: Tank C level indicator is erratic.
Resolution: Replaced elements in sensors
Walt Lafford 8/15/2007 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 9/27/07
Indication: Well A flow rate has diminished.
Resolution: Replaced well pump
Walt Lafford 9/27/2007 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 2-16-08
Indication: Noted transfer pumps at well C were short cycling about ever minute to 30 seconds. Also intermittent low tank level alarm since December even though the transducer showed tank C to be full.
Deduced problem was probably caused by faulty tank probes in tank C causing the pumps to shut down due to erroneous low level condition.
Resolution: Replaced all 6 tank probes and problem cleared out.
Walt Lafford 2/16/2008 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 3/4/08
Indication: Found one of the pressure pumps at station H inoperable
Failed pump was the one close to the west wall for future reference.
Resolution: Replace 35 amp fuse feeding the motor contactor.
Walt Lafford 3/4/2008 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 4/8/08 2:30PM
Indication: Received call from homeowner in Pinion Hills area concerning low water pressure. This area is fed by tank P (unmonitored) on west Promontory.
Resolution: I checked the water pressure on test station on Valley View Dr and noted almost no pressure. Opened tank P and found no water in the tank. Checked circuit breaker on AC panel at lot near manhole, found breaker tripped. Reset breaker and tank began to fill.
Trouble cleared within one hour.
Walt Lafford 4/8/2008 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 7/9/2008
Indication: Call from concerned resident about water coming from overflow on tank F. Checked computer and tank F was over full and tank H was almost empty.
Resolution: Opened tank F and exercised the float switch. Fill valve closed and overflow stopped. Will test function of switch again when tank F level recedes.
Also had to prime pressure pumps at H after the level returned to above 3 feet.
WJL 7/9/2008 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 10/01/08
Indication: Tank A level low and no water transfer from D to A
Resolution: Found the motor control contactor for transfer pump B at station D tripped. Reset contactor and pump is now pumping again.

Date of Trouble: Feb. 13, 2009
Indication:Walt called, while basking in the sun in Arizona and looking at the water system on his laptop, to alert me to the fact that there was a problem at Station B. It was indicating an excessively high water level. However, water flow data suggested that no water had been flowing to that station for the past 12 hours.
Resolution: I crossed my fingers and hoped that the water in Tank B would last until morning. The next morning, I manually started the transfer and well pumps at Station A, to get water flowing to Station B. I then dug through two feet of snow and ice to get into the manhole at Station B. I monitored the current from the level transducer at the Elpro analog input. The current level was about 28ma, on a normally 4 to 20ma scale. Using fixed resistors at the Elpro analog input, I determined that the Elpro unit was functioning properly. I hooked-up a new transducer at the Elpro input, inside the manhole, and it read properly; about 4ma. I then dug through snow and ice to get at the tank cover, while Walt was sipping on a beer in sunny Arizona. It started to snow and blow as I disconnected the transducer at the tank junction box and monitored the cable from the manhole to the tank; it looked OK. Replaced the level transducer in the tank and the analog reading was normal. Reset the pumps at Station A to Auto and the system functioned properly
MB 2/13/2009 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: Feb. 15, 2009
Indication: Walt called again from sunny Arizona. After his morning swim, he was sipping on a iced tea and looking at the water system on his laptop, when he noticed that water had not been flowing from Station D to Station A during the night and the tank at Station A was low.
Resolution: After a closer examination of the data, it looked like the problem started two pumping cycles ago. This probably ruled out the pumps as the problem. I suspected the Low Level Latch circuit, but according to the data, the water level had not gotten below 3 feet. The latch should not activate until the water level gets below 2 feet. While Walt was finishing his iced tea and soaking up the sun, I cleared snow and ice from my working truck and made my way through blinding snow to Station D. The Low Level Latch circuit light was ON. After confirming that the firmware set point was correct (13.3 % or 2 feet), I made sure the pumps did not need to be primed, and reset the Low Level Latch. The problem resulted from Tank A getting too low because of the problem on the day before with the transducer in Tank B. Station D could not handle the demand from Station A when it was trying to catch up, and the water level in Tank D got too low.
MB 2/15/2009 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 3-6-2009
Indication: For the past several weeks the pump flow graph has shown the pump to be cycling on and off at short intervals.
Resolution: Pulled and cleaned or replaced the tank level probes. Dirty probes caused an erroneous low tank alarm condition stopping the transfer pumps from running properly.
WJL 3/6/2009 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 5-20-2009
Indication: High water pressure on Timberline Drive. Reading of 120 PSI at 30503 Timberline and leaking plumbing fixtures
Resolution: Pressure reducing valve PRV located near lot 31 on National Forest Dr failed to properly regulate water pressure after fire hydrant testing. Removed and repaired the PRV. The bypass PRV was not affected. Also replace the defective PRV in Walt's house which allowed the 120psi to affect Walt's plumbing.
WJL 5/20/2009 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 5-19-2009
Indication: No water in fire hydrant located on San Isabel Drive
Resolution: Refilled tank G on National forest Dr. Tank is only used to serve the hydrant and is manually turned off. Need to investigate installation of new electric fill controls and Elpro monitor system.
WJL 5/19/2009 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 8/25/2009
Indication: Wet spot in the road (near the tree in the road) PRV manhole is located just to the east of the tree.
Resolution: Miles Construction opened PRV manhole and found it full of water. Pumped water out of manhole and found water spraying out of a fitting on the PRV. Looked to be a weak area in the wall of the fitting near the threads. Replaced fitting and secured manhole.
WJL 8/25/2009 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 8/25/09
Indication: While inspecting station H found that the emergency engine would not start.
Resolution: Determined battery was defective and replaced battery.
WJL 9/3/09 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 12/8/09
Indication: Tried using batteries from station F to power station I. Found that batteries were not charged. Found that 2amp inline fuse to battery was blown.
Resolution: Replaced fuse. There is no good way to test batteries being charged by AC because the battery voltage reading does not isolate the charger from the battery. Maybe a routine check of the integrity of the fuse is needed.
ELB 12/14/09 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: February 11, 2010:
Indication: While Walt was sipping on a beer and checking out the local sweeties from his pool-side lounge chair in sunny Arizona, Station C stopped pumping water to Station H.
Resolution: The problem was spotted by observing theWeb pageFlow graph. It appeared that Station C had stopped pumping water sometime on Tuesday, February 9, 2010.I waited a day, hoping that the problem would fix itself; it didn't. So, on Thursday,after digging my way through an eight foot snow drift in front of the Station C door, I stumbled inside. After confirming that the well and transfer pumps appeared to work in the manual mode, I remembered that the Off-Peak timer had given us problems in the past. Sure enough, it appeared to be dead. It came back to life after pushing the Reset button. After reprogramming the Timer, the Station seems to be back to normal.
MB 12/14/09 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: February 15, 2010:
Indication: About 3 PM Sara Strongin, located at 30180 Mountian Top called me to tell me she had no water.
Resolution: Strongins are at the end of the pressurized zone. Houses above them had water. Mike Backsen and Steve from Miles and I investigated and found the test value at the end of the pressurized zone was dead as well as two fire hydrants on the 6 inch line which paralleled the pressurized line. Conclusion was that both lines are frozen and the best resolution now is to place a tank in Strongin's garage with a pressure pump to serve the house until Spring allows excavation of the lines.
ELB 12/17/09 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: November 4, 2010
Indication: High water alarm via dialer from tank A
Resolution: Arrived at station to find water coming out the overflow. No pumps running and everything appeared normal otherwise. Shut valves to both transfer pump, no help. Decided only other source could be water entering the lower service area from tank P through a faulty pressure reducing valve. Shut off the PRV on Princeton Circle which feeds water into lower loop from tank P. Trouble resolved, will have PRV repaired and restored to service.
WJL 11/5/2010 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: April 2011
Indication: Well A stopped pumping water
Resolution: Found the control relay located in the well power panel to have a defective coil which prevented the well from responding to calls for water. Replaced relay coil.
WJL 4/22/2011 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: June 2011
Indication: Station H pressure pump 1 not bringing pressure up to 110psi
Resolution: Tried replacing CLAVAL assembly, no help. Replaced pump stack and now pressure is back to normal 110psi
WJL 6/22/2011 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 8/23/11
Indication: Only one transfer pump running at station A
Resolution: Reset heater breaker in east pump control panel. Pump running OK.
WJL 8/23/2011 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 8/16/12
Indication: High level alarm from station A
Resolution: Found water overflowing from tank A at about 6pm. Checked station and found no abnormal pumps running or backflow from tank B. Mike and I determined that there was abnormal usage from tank P at the same time from computer graphs. Deduced that the PRV #1 on Princeton Circle which can feed water back into tank A service area had failed. Upon entering manhole found the bypass PRV had a burst pipe fitting on the control valve. Turned off the bypass PRV and stopped the leak.
Notified Miles to repair the bypass PRV.
Note: ALL BYPASS PRVS SHOULD BE OFF UNLESS THE MAIN PRV IS BEING WORKED ON!!!! ADVISED MILES OF THIS SINCE IT IS HIS EMPLOYEES THAT MAINTAIN THE PRVS
WJL 8/16/2012 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 9/26/12
Indication: The problem was first noticed Friday (9/21/12) night, about the time Walt was sipping on a margarita down in Cancun. It started as an intermittent, with the Well turning On and Off with a period of about 1 hour, and a 50% duty cycle. On Saturday (9/22/12) it failed completely.
Resolution: After some diagnosis, the problem appeared to be in the motor starter and/or the well minder.At that point, Station D was shut down and the Off-Peak timer at Station A set to Manual On, so Wells A & B could keep up with GT water demand. On Monday,Mack Dey was contacted. Mack was not available, due to some recent surgery, so he referred us to Shawn Shake of White Water Systems. Shawn looked at the system and determined that the Pump-Tec Plus Well Minder was bad. There was also a leaky capacitor in the motor starter. He replaced the capacitor and ordered a Pump-Tec Plus well minder. He also did a temporary by-pass of the well minder so we could get Well D back in service. Today (Wed. 9/26/12) Shawn replaced the well minder and we are back to normal.
MKB 9/26/2012 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 10/10/2012
Indication: No wells or pumps running at station A during the daytime run period.
Tanks A and B low.
Resolution: Tried to turn the off peak timer on at station A by pushing the ON button and this did not work. Cycled the timer to Manual and was able to turn the pumps on. Restored the timer to Automatic Mode and again cycled the pumps on and off. Seems to be working now as the pumps did cycle on during the night.
Perhaps it is time to replace this timer with a new one.
Walt Lafford _______________________________________________________________________ _______________________________________________________________________
Date of Troble: 8/21/2013
Indication: No water being pumped from Station D.
Off Peak Timer mulfunction.
Resolution: Replaced bad batteries and reprogrammed timer.
MKB _______________________________________________________________________ _______________________________________________________________________
Date of Troble: 3/7/2014
Symptom: For the past couple of weeks, the water level in Tank E appeared to fill to a higher level
than normal and the level reading became noisy.
Resolution: Replaced level sensor in tank. Readings back to normal.
MJB _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 8/19/16
Indication: Bad water level indication from station B which occurred after a close lightning strike.
Resolution: Replaced the transducer which was not working and the Elpro unit. Seemed to work OK for about a week then the Elpro units power fuse would blow. Replaced the fuse but unit would not hold power for any length of time. Noted that the Elpro would stop working when the B transfer pump shut off. Put the original Elpro back in but noted that the transducer no longer was working.
Days later put the spare Elpro back in and transducer worked fine. Tried causing the transfer pump to run by closing the contacts on the DO-1 port on the Elpro and noted whenever the pump shut down the Elpro unit would power off without blowing the fuse. Removed the battery and AC power from Elpro and restore same, AC first then battery and Elpro would power up OK. Tried same procedure again with same results, Elpro powered down (this happened with either Elpro unit. Apparently the relay which turns the transfer pump on was causing some kind of flyback pulse that the Elpro did not like because replacing the SPDT 12 volt relay fixed the problem. Several cycles of the transfer pump worked fine.
End result of the lightning strike as follows:
Bad transduce
Defective AI-1 port on the Elpro (probably caused by the voltage spike
Defective R1 relay in the pump start circui
WJL 9/5/16 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 12/27/16
Indication: No water at homes served by tank E
Resolution: There is a small box on the pipe between the pump and the pressure tank with a rocker switch that turns off the pump when open and on when closed. There are two available switches in tandem in the box, one wired/active, the other not connected. The spring and contact on the one not wired had broken and fallen inside the mechanism blocking the rocker from closing. After the broken parts were removed, the pump started running normally.
BLP 12/28/16 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 07/2016
Indication: Broken main water line on San Isabelle just north of PRV manhole
Resolution: This large leak occurred when testing fire hydrant on San Isabelle. Hydrant was shut off too rapidly causing a fitting to separate where the main line comes down and Tee's into the street line. The cause occurred because some years ago the PRV was taken out of service and removed from the manhole and no bracing was installed to hold the line in the manhole from pushing into the manhole. Brace was installed between the pipe and the manhole wall.
WJL 7/20/16 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 4/2017
Indication: Erratic transducer readings from tank B transducer
Resolution: Replaced wire from tank to elpro with shielded wire and added conduit. Believe wire was damage by lightning previously. Shield wire is not grounded at either end.
WJL 4/20/17 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 7/2017

WJL 8/20/17 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 8/2017
Indication: Erratic run times at station D well and pumps
Resolution: Replaced timer due to erratic operation
WJL 8/21/17 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 11/2017
Indication: Well A not running when called for
Resolution: Replaced the 110 Volt control relay at the well head. Also had to adjust the master power lever on that controls the contactor to apply power to the panel, power would not come on when lever was operated to the on position.
WJL 11/20/17 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 05/2018
Indication: Homeowner reported low water pressure in home
Resolution: Measured water pressure was about 30 PSI. Attempts to adjust the PRV were unsuccessful so we checked 2 other homes on the same street, Northwoods Circle and found their pressure to be around 40 PSI as they were at a lower elevation this seemed about the same. We opened the manhole by the mail center containing the PRV serving this neighborhood and found the outlet pressure was set at about 55 PSI and it should have been at 67 PSI. We adjusted the regulator to about 70-75 PSI and we were able to attain 45 PSI at the home.
WJL 05/08/18 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 06/26/2019
Indication: Report from users of no water on Creek Run.
Resolution: Found tank I empty. Refilled the tank manually by operating the valve in the adjacent manhole. Trouble was caused by a defective pressure transducer in tank I showing tank full indication. Replaced transducer with spare, trouble resolved.
WJL 06/26/19 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: May 2020
Indication: High water usage on tank B.
Resolution: After months of locating work the leak was found on a service line to a home on Overlook Drive. There was a split in the plastic line going to the home from the curb valve. Replaced defective part of the line and the curb valve.
WJL 05/08/20 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: June 3, 2020
Indication: Erratic level readings from tank H.
Resolution: Replaced transducer on tank H and reprogrammed Elpro for new transducer range of 11.5 feet.
WJL 06/03/20 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: July 2020
Indication: Zero level reading on tank E on GT Water.
Resolution: Replaced defective transducer in tank E.
WJL 07/08/20 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: August 2020
Indication: No level readings from tank D.
Resolution: Replaced level transducer on tank D, this seemed to resolve the problem and good readings returned. Two days later we lost all level data from tank D. Found the Elpro unit not sending and receiving data properly. Cycled the power on the unit and noted the battery had failed to maintain operation of the Elpro unit. On inspection found the battery to be only 8 volts not 12 volts. Replaced the battery and everything has been fine for a week now.
WJL 08/08/20 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: December 21, 2020 (resolved January 22, 2021)
Indication: Tank F not filling
Resolution: On December 21, we replaced the switch on Tank F but that was not the problem. Identified the problem to be the fill control valve located in the manhole on Eagles Ridge. The valve was completely frozen when we attempted to manually turn it on. The insulating foam cover inside the collar of the manhole had fallen into the hole thus letting cold air into the manhole. Foam cover has been fixed and a tarp placed on the pipes/valves. January 12 – Received new Bray Series 70 Valve controller (equipped with a small heater – wire coil) and removed old controller. Miles was not able to manually operate valve. We determined that we needed a new valve as well. January 22 – Replaced valve and installed new valve controller. From December 21 to the fix on January 22, we would manually fill tank F from Tank I by operating the valve in the manhole by Tank F. Only needed to do this a few times.
SL 02/03/21 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: July 2, 2021
Indication: Tank H shows zero level on SCADA however tank is overflowing
Resolution: Detected lightning strike yesterday close to tank. Found the level transducer was fried and the Elpro analog input port was also not working. Replaced transducer and the Elpro unit.
WL 07/02/21 _______________________________________________________________________ _______________________________________________________________________
Date of Trouble: 10/4, 2021
Indication: No water level reading on the SCADA for tank I
Resolution: Found that the current reading on the transducer was way out of limits and constantly changing. Replaced the transducer and proper levels on the SCADA returned.
