On April 2 City Council approved a water conservation credit program for single-family homes.
Staff said the program is intended to encourage residents to conserve water.
The program allows utility customers to apply for credits to their water utility bills if they install certain water-conserving home improvements.
Staff said cities in the Metroplex, such as Allen, Frisco, McKinney, Plano and Carrollton, have similar programs.
The maximum credit available is limited to $375 per single-family residential address per fiscal year.
Credits include up to $50 for a low-flow toilet, up to $75 for a high-efficiency washing machine, up to $25 for a rain barrel and up to $50 for an irrigation system inspection—a licensed irrigation professional registered with the city of Lewisville must do the inspection.
Some of the improvements require special criteria.
Residents must provide a copy of the original invoice or sales receipt and copy of the barcode or proof of purchase.
The city has allocated $100,000 per fiscal year for the program. Council has the ability to revisit this amount in future budget years.
