Construction of Wells 21 and 22, RO Water Treatment Plant, and Wellhead Facilities

Butier Engineering, Inc. performed construction management and inspection services for the construction of Wells 21 and 22 located in the cities of Irvine and Tustin, CA. In addition to the wells, Butier provided CM and inspection services for construction of a reverse osmosis (RO) water treatment plant and wellhead facilities. The following improvements had to be completed before groundwater from Wells 21 and 22 could be introduced into IRWD's potable water system:

Reverse Osmosis Water Treatment Plant

Major process elements and facilities include cartridge filters, chemical storage and feed systems, RO membrane feed pumps; RO membrane trains, decarbonators for post treatment pH adjustment and stabilization, product water pump station, 0.15 MG clearwell for product water storage, and storage/electrical building.

Wellhead Facilities

Due to the proximity of the wells to existing residences, each well was equipped with above ground, constant speed, vertical turbine pumps and motors housed in a sound attenuated building.
