PWS D1280268
Dear Mr. Turnipseed:
Thank you for your assistance in conducting the survey of the Diamond Bar Estates water system on March 27,
2012. I appreciate you sharing your knowledge of the water system. The system appears to be well run and was
mostly in compliance with ldaho Rules for Public Drinking Water Systems.
The following items were found during the course of the survey. Within 30 days of receipt of this report, a
representative from the Association must contact the DEQ to discuss the Association's plan to address these
items:
I)eficiencies
l.) The pressure relief valve located on well head#Z must be replaced with an appropriate screened vent as
required by IDAPA 58.01.08.5 1 1.05.
Additional Requirements
1.) A written total coliform sampling plan for Diamond Bar Estates water system could not be located in
DEQ files; please submit a copy of this plan to DEQ. IDAPA 58.01.08.002.01.a & 40 CFR Parts
lat.2t(a)1.
Recommendations
l.) DEQ recommends all valves are exercised on an annual basis.
2.) DEQ recommends all distribution lines are flushed on an annual basis.
At this time, the system has been determined to be in compliance with the ldaho Rules for Public Drinking
Water Systems. At such a time that the items above arc corrected, the system will be determined to be in full
compliance with the Rules. Please contact me at 208-6664612 with any questions or concerns you may have
regarding these issues.

System Summary
The Diamond Bar Estates water system is a community water system serving the Diamond Bar Estates
and Boekel Estates subdivisions, located north of the Coeur d'Alene Airport in the vicinity of Ramsey
and Boekel Roads. Well #1, pump house #1, and the reservoir are located on a well lot offRodeo
Road, within the Diamond Bar Estates subdivision. Well #2, which primarily firnctions as a back-up/
emergency source, is located on property owned by Mr. Tumipseed, near the corner of Atlas Road and
Boekel Road. The Diamond Bar Estates water system is aprivately owned water system that is
regulated by the Idaho Public Utilities Commission.

Well #1
Well #1, pump house #1, and the 55,000 gallon reservor are locaterl on a well lot (Lot 999, Block I ot
the Diamond Bar Estates subdivision - dimensions of approximately 213 feet by approximately 240
feet), all of which are owned by the Diamond Bar Estates water system. Perimeter fencing encloses
the weii iot, and rhe pump house is iocke<i ro proreq against unauthorizeci entry. a<iequate heating and
ventilation are also provided to the components located within the pump house.

125 was set from a depth af 342 ftet tc -?-<2 ftet, s:ld a screen',','ith a slot size of 100',';as set from 352

properly vented and screened.
Per the Department ot'Envronmental Qualty (DEQ) records, the well pump rs a llerkely 60 hp
capable of producing 570 gallons per minute and is actuated by a float system in the 55,000 gallon
reservoir. In normal operation water is drawn from the reservoir and discharged to distribution via two
i0 hp submersibie boosrer pumps within the reservoir rhar operare in an aiternaring ieadiiag rorarion.
In the event that these two booster pumps cannot keep up with demand, a third, 20 hp booster pump
(a.k.a. the fire pump) will be activated. The alternating lead/lag booster pumps are controlled by

Schematic of the Distribution System (Diamond Bar Estates portion)
In 2005, engrneered plans were approved by DEQ, and an E-rnch water marn lrne was extended ott the
6-inch main line on Atlas Road to serve the l2lot Boekel Estates subdivision. The 8-inch main line
was extended west under Atlas Road and then north under Boekel continuing to CJ Court. The 8-inch
main terminares ar rhe cui-de-sac at the end of Ci Coun, where a biow-offassembiy was insmiieci to
flush the dead end. According to Mr. Turnipseed, this dead-end main line is flushed biannually.
Tweive fire hycirants are iocateci on the ciistribution sy$em, and meet the fire frow requiremems of the
Northern Lakes Fire District per Mr. Turnipseed.

Storage
The 55,000 gallon partially buried concrete reservoir is located underneath pump house #1. In normal
operatlon the well clischarges to the reservoff, actuated by a tioat system rn the reservolr; water rs tnen
discharged to distribution via submersible booster pumps. If the need arises to conduct maintenance
on the reservoir, it can be isolated from the system and the well can pump directly to distribution.
A 6-inch combination screened vent/ overflow is installed on the south side of the reservoir. The
exrstrng topography does not allow tbr an elbow to be mstalled on thrs overtlow, wrthout creatmg a
discharge point at or very near to the ground surface. An access hatclil cover is located on the
northwest corner of the reservoir within the pump house, and appears to provide adequate access and
prorecion. The minor cracks identified on the reservoir rooi<iuring the 2006 survey have since been
sealed.
