Orange County Water District selected Butier Engineering, Inc.—in partnership with Carollo Engineers—to provide construction management services for the Groundwater Replenishment System (GWRS) Final Expansion. The water reuse project will create an additional drought-proof drinking water supply for over one million people by expanding the existing 100 MGD Advanced Water Purification Facility to 130 MGD; constructing Plant No. 2 Secondary Effluent Conveyance Facilities; and rehabilitating an existing pipeline between Plant 1 and Plant 2 to bring secondary effluent to the GWRS. The total estimated cost of construction is approximately $188 million. Construction will begin in 2019 and be completed by 2023. Additional Butier team members include ON-SITE Technical Services, Inc. and Environmental Science Associates.
