DATE: November 3, 1997
SUBJECT: City Council Meeting, November 13, 1997
ITEM: 10H. Consider a resolution authorizing the Mayor to execute
Amendment No. 4 to the engineering contract with Camp Dresser
McKee contract for the Water Treatment Plant.
STAFF RESOURCE PERSON: Jim Nuse
STAFF RECOMMENDATION:
The new water treatment facility was designed to accommodate changes in
treatment processes for future Federal rules and regulations as mandated under the Safe
Drinking Water Act, SDWA. The water treatment plant was brought on -line this summer
and operational data indicates that levels of Total Trihalomethanes (TTHMs) can be
exceeded under certain plant process situations. Further tests conducted by city staff
indicates a need for a chlorine contact basin to ensure accurate dosage of ammonia for
production of chloramines.
This problem was anticipated in the design by constructing piping stub -outs in the
finish water line immediately after the treatment structure. These stub -outs will help
facilitate the construction of the contact basin. Additionally, the basin will provide increased
finish water storage.
City staff recommends amending the engineering contract and assigning the construction
to the existing contractor.
