The collections system consists of approximately 110.0 miles of sewer gravity lines and force mains ranging in size from two (2”) to twenty-four (24”) inches in diameter, and seventy-nine lift stations that take wastewater from individual residences and businesses via local area collection lines to the water reclamation facility. The gravity system includes 1,302 manholes for maintenance and operational access
Nine Vacuum Collection areas have been constructed and comprise 126.2 miles of vacuum collection lines ranging in size from three (3”) to ten (10”) inches in diameter, approximately 56.2 miles of gravity service mains and 53.8 miles of force mains. A series of 3,089 valve pits transmit sewage to 7 vacuum stations, 13 low-pressure stations and 1 vacuum booster station.
These 870 square foot buildings contain the mechanicals necessary to maintain a constant vacuum within the area. Four collection pods that can be isolated in times of low-vacuum readings bring sewage to a 4,200 gallon collection tank, and subsequently via the force main system to the treatment plant.
