Successful Implementation of a Fast Paced Agreed Order
Abstract:To reduce the Sanitary Sewer Overflows (SSO), City of Houston submitted a Collection System Sanitary Sewer Overflow Plan and Schedule (Plan) to the Texas Commission on Environmental Quality (TCEQ) in May 2004. The Agreed Order (AO) became effective in November 2005. The Plan includes cleaning and rehabilitation of sewers, preventive maintenance of lift stations, strengthening of the grease control ordinance and a Supplemental Environmental Project (SEP). The City began implementing the plan in Fiscal Year (FY) 2005, and the program will end in FY 2014. The Plan is estimated to cost 750.00 million. The planning, engineering and construction management is performed in-house, resulting in a savings of approximately 4.0 million per year. A greater than 60 percent reduction in SSO has been observed after the Plan implementation.
