OPERATIONS & MAINTENANCE UPDATE
The Operations Manager presented an update on maintenance and production activity for
the month of August 2017; he reviewed charts that represent various activities related to
district operations and maintenance including the District’s preventative maintenance
program. He stated the District experienced a spike in leaks due to increased water usage
associated with warmer weather.
The Operations Manager stated that water production reports showed a decrease in water
usage from July to August; and the District operated using 80% groundwater and 20% surface
water, and did not purchase any State Water during the month of August.

WATER SYSTEM RELIABILITY
The Director of Engineering and Operations stated that in March, the District exceeded its
fourth quarter average for TTHM’s at Plant 134. The District notified all customers of the
violation, and held a public information workshop to address any customer concerns as well
as posting weekly water sample information on the District’s website. During the six-month
period following the exceedance, the District implemented measures that successfully
reduced the TTHM levels, and is expected to be within compliance during the next reporting
quarter.
ADJOURN
The meeting adjourned at 3:00 p.m.

From: O perations Manager
S ubject: Valve R eplacement at P lant 56
R E C O MM E N D AT IO N:
T his rep ort is p rovid ed to the Engineering and O perations C o mmittee fo r its info rmatio n o nly.
B AC KG R O UN D / AN ALYS IS :
T he Distric t maintains 15 different s torage fac ilities thro ugho ut the s ervice area. A c ritic al comp o nent o f thes e
s ites is the ab ility to c ontrol incoming and outgoing water flo ws . R ecently, p ro d uctio n s taff identified a d amaged
10-inch is o latio n gate valve in need o f rep lac ement at P lant 56. T his locatio n is a 500,000 gallon water s torage
reservo ir o n S has ta Drive no rth o f the S an Manuel C asino .
T his valve at P lant 56 is c ritical in allowing water to flo w from the F o o thill zo ne into the s torage res ervo ir. Water
from the res ervo ir is s ent through b ooster p umps to the C anal zo ne. T his is an important p art of o ur distrib ution
s ys tem bec aus e it allows us to sup p ly water at a variety of elevatio ns.
T he identified valve wo rks in c o njunctio n with ano ther valve to allow o perato rs to ad jus t an altitude control valve
whic h determines the water level o f the reservo ir at P lant 56. Due to the d amaged gate valve, o perato rs were
unable to perform the req uired maintenanc e on the important contro l valve and will not have the ab ility to ad just
the water levels in the reservo ir at P lant 56.
To replac e the d amaged gate valve s taff identified two o p tions. O p tion one, we c o uld comp letely drain the tank
and s imply rep lac e the 10-inch valve. Draining of the tank is a time-cons uming p ro c es s whic h requires c areful
p lanning to ens ure water sup p ly reliability and very s p ecific s amp ling req uirements to allo w the tank to be p lac ed
b ac k o nline. O p tio n two , wo uld b e to hire a c ertified S C UBA tank d iver to temp o rarily plug the p ip e ins ide the
reservo ir which wo uld allo w the tank to remain full of water and in s ervice, while o ur crews s afely rep lace the
need ed valve. S taff evaluated the two o p tions and determined it would be bes t to keep the res ervo ir in s ervice.
