Updated, Thursday, March 25, 2020: Due to the COVID-19 disease outbreak, the residential water conservation credit program has been suspended until further notice.
The City of Lewisville encourages residents to conserve water and has created a single-family residential water conservation credit program. This program allows utility customers to apply for credits to their water utility bills (up to $375 per year) to offset the costs of certain qualified water conserving home improvements. The table below outlines these improvements, and more specific information is available on the individual credit application forms.
Water Conservation Credits are only available for purchases or improvements starting on the inception date of the program, April 2, 2018, or later.
For more information, please contact Mendie White, Sustainability Manager, email@example.com or 972.219.3503.
