Butier Engineering, Inc. was selected as the construction manager for the $35 million 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 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.
