Wastewater Collection & Treatment Program
As of December 31, 2009, the SAWS Wastewater Collection and Treatment system consists of approximately 5,085 miles of sanitary sewer mains, 164 lift stations, and 3 major wastewater treatment plants. The Wastewater CIP consists of programs and projects to upgrade and rehabilitate the wastewater collection and treatment systems, and increase their capacity to allow for future growth.
The wastewater component of the CIP focuses on sustaining aging collection systems, maintaining compliance with regulatory requirements, and supporting wet weather and operational demands. A major focus continues to be repairing and adjusting wastewater mains in coordination with the City of San Antonio's bond program.
Collection system projects funded in 2011 will rehabilitate critical mains and also continue to add capacity on the rapidly growing South side with the third and fourth out of six segments of the Medina River Sewer Outfall starting construction. Funding will also be provided to the continuation of a comprehensive lift station assessment and rehabilitation program that will ensure these critical facilities remain in full compliance with State regulations, industry codes and best management practices. Large collection lines in the Eastern, Central and Western sewersheds will be upgraded to expand their capacity. Another major effort is rehabilitating sewer lines to reduce the occurrence of sanitary sewer overflows.
The wastewater treatment component of the 2011 CIP includes projects that will upgrade the Dos Rios treatment plant to accept the additional flows from the Medina River Sewer Outfall.
