UPPER ZONE PIPELINE PROJECT
The Director of Engineering & Operations provided information regarding the Upper Zone
Pipeline Project; he explained the complexity of the current structure of water distribution;
he stated that the project will use gravity to pull water down and make plant 134 self-
sustaining; that this distributes water throughout the District as broadly as possible, making
it consistent with the District’s vision and addresses water quality concerns.
The Director of Engineering & Operations noted that the project requires the installation of
a 16” line at Victoria and Highland; and the District will ask for bids that will include
specifications to address traffic concerns for the installation.

B AC KG R O UN D / AN ALYS IS :
T he O p eratio ns Department us es a variety of to o ls and metho d s to monitor and trac k all maintenanc e ac tivities
that oc c ur within the dep artment. T he attached mo nthly report pro vides the p revio us year average and the c urrent
ac tivity o f the mos t c ritic al items . T he tracking o f these items helps ens ure that the d ep artment achieves the go als
and o b jec tives determined to b e imp ortant for eac h year. A few imp o rtant items ro utinely trac ked is water
p roduction, water s o urc e, and energy us age. By comp aring the present year to the p rio r year average on thes e
items gives us key information regarding water us age, cons ervation effo rts , how efficient energy is us ed within
the Dis trict as well as provid ing valuable info rmation used to develop the next years ’ op erating bud get.
A number of maintenance ac tivities are als o trac ked and mo nitored s uch as leak repair, valve and fire hyd rant
maintenance, s ewer main line c leaning and s ewer main line camera. Mos t o f the ac tivities are ro utine and
p reventative maintenanc e that is perfo rmed every d ay to maintain and ens ure that the Dis tric ts infrastruc ture is in
top s hape. Every year, maintenance ac tivities are programmed for comp letion and the monthly monito ring
ens ures the go als are met. Leak repair is a reac tive ac tivity and us ually as s o ciated with aging water pipes.
Trac king leak repairs p ro vid es valuable ins ight into the areas that are in mo s t need of c o ns id ering a C apital

From: Direc tor o f Engineering & O perations
S ubject: Water S ys tem R eliability
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 Dis tric t has a s ervic e area which c o vers 30 s q uare miles and serves a populatio n o f ap p roximately 102,000.
T his d emand is served by a comb ination o f groundwater, s urface water and imp o rted water. T he District
c urrently p ro d uces gro und water from 16 wells which have a c o mbined capac ity o f just over 32 million gallons
p er day (MG D) whic h is well in exces s o f the average demand o f 17 MG D needed to s erve the District
c usto mers. T his combined with up to 8 MG D of s urfac e and/o r imported water treated at P lant 134 gives the
District needed flexib ility in s erving our cus to mers when water q uality is s ues arise.
Early this year the Dis tric t fac ed challenges with water q uality due to the fo rmatio n o f Total Trihalo methanes
(T T HM) within the s urface water treated at P lant 134. T T HM is generated from an interactio n between Total
O rganic C omp o und s (T O C ) found in the s urfac e water and the c hlorine us ed for disinfec tion p urpos es at the
treatment p lant. During this perio d , the amo unt of water p ro d uced at the p lant was red uc ed and mo re water was
p ump ed fro m Dis tric t wells whic h are rarely imp ac ted b y TO C . Altho ugh the Dis tric t has adequate fac ilities to
meet the demands o f our c us tomers , us ing exc lusively ground water, maintaining a diverse po rtfolio o f sup p ly is
important.
W hile TO C is no t a typic al c ontaminant found in gro undwater, other c o ntaminants are commo nly fo und
d epend ent upon loc ation. T hese inc lude Ino rganic s suc h as Nitrates, Ars enic , and F luo rid e, Volatile O rganic
C ompound s (V O C ) s uc h as P erchlo ro ethylene (P C E), and R adiologic s s uc h as Uranium. Lis ted b elow are
s ites within the Distric t which have c hallenges with some o f thes e cons tituents :
1. F luoride is p res ent at P lant 39 whic h p ro d uces 1,500 gp m. Water produc ed at this s ite is blended with
other sys tem water to red uc e the level o f F luoride p rior to us e.
2. P erchlo roethylene (P C E) is pres ent at P lant 28 whic h p ro d uc es 1,600 gpm. T his fac ility currently us es
G ranular Activated C arbon (G AC ) to remove the P C E.
3. Uranium is p res ent at P lant 40 which pro d uc ed 1,500 gpm. A treatment fac ility was ins talled at this s ite;
however, it was ultimately determined that it was no t c o s t effective to treat this well and has s ince been
abandoned.
R espec tfully s ubmitted :
S teven Nix, P.E.
Direc tor of Engineering & O p erations
4. P lant 9 whic h pro d uc es 1,500 gpm was recently taken out o f servic e for routine s ervic e repairs . During
this down time, ro utine annual tes ting was perfo rmed and this site has tested above limit fo r R ad ium.
Altho ugh treatment is availab le, it is c o s tly and therefore likely that this well will b e abandoned .
5. In the p as t 10 years, the Dis trict has taken wells 12, 27 and 107 o ffline and were ultimately ab andoned due
to P erchlorate.
Although the Dis tric t has been c hallenged with these various c o ntamination issues , the Dis trict has mo re than
adequate resources to provid e s afe and reliable water s upp ly to its cus tomers no w and into the up coming
future.
