Rainwater Harvesting Systems Ordinance

All rainwater harvesting systems are required to comply with the City's Rainwater Harvesting Ordinance, but a permit is only required when the total cumulative capacity of all storage tanks or rain barrels on the property exceeds 400 gallons. Additional permits may be required for systems that have permanent electrical or mechanical features, such as electrical pumps. Contact the Building Inspection Department at 972-744-4180 to obtain a permit.

Residents who wish to install systems that have a cumulative capacity of less than 400 gallons must register their system by following the link below. There is no fee for registration.
