Attention: Mr. Jack Wilson Water Quality - Talbot Reservoirs
City Engineer
GentlEmen:
It is understood that further complaints nave been received with regard
to the Quality of water supplied to customers by the City of Renton, and that
these customers are supplied .later from the City's supply, storage, and dis-
tribution facilities rather than those facilities which distribute water
purchased in oulK from the City of Seattle. There is visible evidence of
Pollution of water stored in the uncovered Talbot Reservoirs, and maintenance
procedures have been instituted to minimize this problem. These reservoirs
are the most likely cause for complaints, and it was recommended in our 0ctober,
1965 study of the water system that they be covered. Now that the second High-
lands Reservoir has been roofed, the Talbot Reservoirs are the only ones which
are not covered. However, by letter dated 3 July 1967, we recommended that
roofing at Talbot be delayed for twelve months. Our reasons for so doing am
explained be'.ow.
The southeast area of the City has great potential for develoorent and
muc,i has in fact taker, place in the last three years. The area is of consider-
dble extent with variation in elevation, and dissection by the freeway, electric
transmission lines, and large Seattle water pipelines. It is difficult to plan
for an orderly, economical expansion of the water supply facilities. It is our
opinion that the development should be kept continually under review so that
planning and construction can keep ahead of demand without expending large sums
of money before the necessity arises.
We will shortly make a recommendation on the facilities to to constructed
in the next finanL,dl year, and this will involve placing an order of priority
on storage reservoirs, pump stations, and pipelines, the complete program
involving a considerable amount of money within the next five years. The pace
of development has accelerated beyond that anticipated in our 1965 study.
City of Renton
18 :illy 1968

It will probably be our recommendation that first priority be given to
,.unstruction of an elevated storage tank at Rolling Hills to provide a
continuous supply of water to that expanding area. Under present circumstances
the consequences of an electric power failure to the Tiffany Park pumps,
damage to the siny:e disc:iarge main leading from the pump station., or a shut-
down of the large Seattle pipeline would deprive the Tiffany Park and Rolling
Hills area of a supply of water since no storage presently exists. This would
be inconvenient for domestic purposes, but could be serious in the event of a
major fire.
Other requirements will be provision of thre- million gallons of ground
level storage at Rollino Hills with a booster pump station to supply the
elevated tank when service from Seattle is di=_continued. In addition, five
million gallons storage at Talbot should be provided soon with a further five
million in the future and a system of booster pumps and the lE-inch pipeline to
Rollinc kills. When this orogram is implemented, the existing circular Talbot
Reset r may become a clear well for pump suction, and the old rectangular
rese. , .ir should probably be abandoned.
For the above reasons we are unable to recommend expenditure on permanent
roofs to either reservoir, but do consider both reservoirs should be covered.
Cinsiderable advances have been made in the technique of providing low
cost, flexible linings to old reservoirs and constructing coverings floating
on the water surface. We therefore recommend that a flexible, floating
covering he provided on both reservoirs, and that a liner of flexible material
be installed in the old reservoir at comparatively small expense while a
specialist rantractor is on the Job.
In our opinion the work involved is of a special nature and calls for
tight specif.cations and close supervision. We have experience of this type
of work and :suggest we prepare the specifications and supervise construction.
We wnul6 be cleased to submit a proposal for engineering services at the
appropriate time.
We estimate the cost of covering both reservoirs and lining the older at
approximately $10,000.00, inclusive of engineering services.
It migct be possible to prevent contamination of the stored water by
mosquito larvae by installing a compressed air system to continually agitate
the water surface. However, it is our opinion that this would be a palliative
only and not a desirable cure to all forma of contamination. We do not reco.n-
mend this alternative.
If we can assist further, please call upon us.
Very truly yours,

Renton, Washington 98065
Dear Jack: Talbot Reservoirs
we have reviewed the proposal dated 30 November 1968 made to the City
by Staff Industries Inc. , throagh Gard Kennedy, Factory Representative, and
Comment as follows°
The proposed methods of lininq the rectangular reservoir and covering both
reservoirs to prevent air-borne contamination are acceptable. The warranty
of replacement f the PVC sheeting for weather deteMoratinn on a five-year
basis, which we interpret to mean materials only, anpears reasonable. Based
upon dur experience with this material and workmanship i. the past, we would
not expect further warranty to be necessary.
the estimated costs given in the proposal include assistance by City
forces, The only labor quotation is 5150.00 per day for sunervision by the
factory representative.
We recommend acceptance of the proposal at the quoted cost for PVC material,
adhesive, and supervision, Freiqnt would be at actual cost. it is suggested that an
order be issued covering all items of the proposal, except labor, with OR City
reserving the right to purchase locally anchor bolts, 1' by d" wood stripping, etc. ,
and providing or renting locally the necessary grinders and drill. It may be
that administrative costs and inconvenience to the City would offset any economy
obtained by not aceptino these items of the proposal.
It is recommended that the caries around the reservoir inlets and outlets
be fabricated in the City shops, but the design responsibility should be
that of Staff Industries to protect the PVC material against unnecessary abrasion.
(Mce the covers have been installed there is a remote possibility that a rdt or
other animal could enter the reservoirs by way of the inlet pipes from
Lice valve House and their presence not be known. It is recoiwended therefore
that coarse screens be installed at the entrance to these pipes in the
valve house.

Dear W. Bjork:
Tee City of Aaatoa Water Departsgbt iastolled plastic ta"to on two reservoirs
about four year* ago.
Jur experience is that it gathers the rain water, which forems co top of the
plastic according to the amount of rain. we have one went who puep* the rate
ester off after inclement weather.
,he water stay* to the folds and attract& birds, att. Atop, deari, loaf golds,
sat foreign hodt" collect in the water, causlig tempura conditions. Wale*
were farad oy blowy objetta Cnrwn by childrrr, and repairs are costly to
manpavor to puii the heavy plastic skin to Lila aides for the repairs. In told
weather, repairs or* nest to impossible sines it is necessary to beat the
plastic tc obtain tbs proper repair.
1 to not think that floating plastic cowers are feasible dum, to the problem
of emiaing the cootasttoated water tt.at sets on top of the corer, and when a
last oemrs, it mina with the good water.
Very truly yours,
Warren G. Gnonaaon, P.G.
