Project History:
Phase I of the Clinton Water Treatment Plant (WTP)
expansion was completed in 2002 through a modified design build approach.
Phase I of the expansion improved the raw water pumping, filtering capacity,
transfer pumping and various electrical/mechanical systems. The phased
implementation of the Clinton WTP expansion provided the flexibility to the City
of
The 2003 Master Plan provided a schedule of work for completing Phase II of the expansion. The project will increase capacity to meet projected customer demands, improve reliability of the water treatment facility, and provide for future treatment processes if needed for upcoming regulations. The improvements will complete the expansion of the water treatment plant to a firm capacity of 25 million gallons per day (mgd) and hydraulic capacity to 30 mgd. This will include new basins, high service pumping, electrical improvements and miscellaneous building/chemical feed improvements.
