The City of Sugar Land’s wastewater collection system includes approximately 2.6 million linear feet of sanitary sewer pipe, about 133 lift stations, approximately 16,450 sanitary sewer manholes, and four (4) wastewater treatment plants, North Wastewater Treatment Plant (North WWTP), South Wastewater Treatment Plant (South WWTP), West Wastewater Treatment Plant (West WWTP), and Greatwood Wastewater Treatment Plant (Greatwood WWTP). Gravity sewer mains, force mains, lift stations, and gravity interceptor mains convey the flows to the wastewater treatment plants. 

In continuation of the City’s bi-annual wastewater collection system evaluation program, sanitary sewer collection system study and evaluation was completed in February 2024. The study identifies critical wastewater lines needing repair and rehabilitation. The critical wastewater lines were selected by a risk rating system that was developed based on the pipes’ size, material type, age, and depth.

Approximately 67,860 linear feet of 6-inch to 18-inch sanitary sewer collection system lines was investigated for possible infiltration/inflow issues in the February 2024 study and evaluation.  About 41,030 linear feet of the sanitary sewer collection system lines evaluated were identified to be in a deteriorating stage and in need of repairs/rehabilitation. 

The design contract for the recommended repairs/rehabilitation lines was approved by City Council in April 2024, and the design was completed in December 2024.
