Document Description
Irvine Ranch Water District (IRWD) Wells 76, 110r, 115r have experienced decreased
production over time. Recent inspections and review of the flow data for these three wells have determined that each well will require rehabilitation in order to restore their respective capacities. Work to be performed on these wells involves mechanical cleaning, including wire brushing, scrubbing the well walls, repair of any wall defects, swabbing and airlifting. The wells will be redeveloped, chemically treated and tested. Work will include necessary repairs and replacements of the pump and motor assemblies. There will be no expansion of use of the respective well sites as a result of this project. Additionally, IRWD will abandon wells 72 and 106, which have reached the end of their useful life. The abandonment of these wells will involve removal of above-ground equipment, pipeline replacement, and electrical equipment removal. Well 106 will also have approximately 10 x 10 feet concrete pad removed. Both Well
72 and 106 would also involve approximately 10 feet of excavation and back filled with grout end sack cement, completing its abandonment process. All of the work would be done in compliance with the State waterwork standard.
