Special Impact Fee by Agreement

A Special Impact Fee by Agreement was approved by SAWS Board of Trustees to aid in responsible development over specific areas of the Edwards Aquifer Recharge Zone. These areas are currently served by sewer lift stations.

As development occurs, each of the developments would typically be required to make improvements to the lift stations or build additional lift stations to serve their property. To prevent multiple sewer lift station improvements to the existing lift stations as well as additional lift stations, SAWS collects the Special Impact Fee by Agreement (Lift Station Escrow Fee) which will be used by SAWS to make regional improvements to the existing lift stations or partially fund the extensive sewer gravity outfall network in the future.
