Description

Under the Consent Decree, the existing Deep Springs Pump Station was replaced with a new Class B pump station and building, and upgraded to include an increase in firm pumping capacity to 3.5 MGD. The associated 280 linear feet of 10-inches force main was also upgraded to handle the increase in flow. Three new 900-gpm submersible pumps with Variable Frequency Drives (VFDs) were installed in three separate wetwells, allowing any one pump to be taken out of servie without reducing the capacity of the pump station. The new pump station was also fitted with a 500 cfm carbon absorber odor control system, a 300kW natural gas generator, and a magnetic flowmeter. Since the project site was located in a residential area, the pump station was designed to resemble a house, complete with decorative residential lighting, metal roof shingles, and appropriate fencing and landscaping.
