Halls Bayou-Westfield Estates: Watershed Protection Plan Implementation

Houston-Galveston Area Council implemented low-flow water devices, a pet-waste program, and outreach for managing on-site wastewater facilities in Westfield Estates.


Westfield Estates is a small neighborhood in an unincorporated portion of Harris County that contributes drainage to the Halls Bayou watershed. The community is served solely by on-site sewage facilities (OSSFs), such as septic tanks, many of which are failing due to problems in design, maintenance, or operation. The failing OSSFs, combined with bacterial contamination from domestic animals and other wildlife, have led to elevated fecal bacteria levels in the watershed that exceed the state’s criteria for primary contact recreation.

The Westfield Estates Watershed Protection Plan (WPP) was developed by stakeholders and the state, led by an interdisciplinary stakeholders’ advisory group to improve water quality. The goals of the WPP are to reduce bacteria levels, institute both structural and behavioral best management practices (BMPs) to improve water quality, and raise awareness of water quality issues in area residents.

Project Description

Houston-Galveston Area Council (H-GAC) implemented BMPs specified in the Westfield Estates WPP. Structural measures include installation of low-flow water devices to reduce pollution from OSSFs and an incentive program to reduce pollution from pet waste that includes waste-disposal facilities and waste recycling. Public awareness of pollution prevention was raised through educational materials, meetings, and community events. H-GAC completed the project in December 2012.
