From 1980 to 1984, the plant was expanded to 15 MGD and twenty center pivot units on 2,000 irrigated acres were installed at Spraberry. In 1990, we added 700 irrigated acres at Spraberry. Plant construction was started in September of 1996 and the Plant was placed in full operation in February 1999. The new interceptor sewer along I-20 relieved sewer overloading conditions in the south part of Midland and allowed us to commission the 50 year old Air Terminal Treatment Plant. The plant can be easily expanded to treat a design flow of 28 MGD for a population capacity of 173,000.
Additional acreage is permitted to handle current plant capacity.
