Background
The Cholla Water Treatment Plant (CWTP), which includes the booster pump stations and administration building, were built in 1978 and expanded in 1988. The administration building consists of a lobby, control room, laboratory, instrument shop, conference room, offices, bathrooms, and miscellaneous storage.
The CWTP provides potable water to Zones 1 and 2 of the City. There are three booster pump stations that pump the water through the distribution system. The Zone 2 station was built in 1972 and expanded in 1982. Zone 1A was built in 1981 and upgraded 2000. Zone 1B was constructed in 2000.
The project consists of an evaluation study (phase 1), design services (phase 2) and finally construction services (phase 3).
As with all water treatment facilities, there is periodic need to evaluate and rehabilitate current treatment systems to ensure the infrastructure is reliable and in good working condition. Improvements to major components require separate evaluation and design phases prior to the construction.
Analysis
From the November of 2014 Request for Proposal selection process, HDR was selected to perform an evaluation study of the processes and equipment condition at the booster pump stations and the various function areas within the administration building. This amendment for $779,183 will include design services to implement the improvement recommendations. Amendment 2 for construction administration services will be brought to the Council at a future date.
