Swale Liner Installation

The primary function of a swale liner is to maintain an acceptable swale grade in which to convey stormwater into the Drainage Right of Ways (DROWs).

Our city has more than 1,600 miles of swales that are designed to collect stormwater and remove this water from the city streets and all property. Swales convey this stormwater into Drainage Right of Ways (DROWs), which delivers the runoffs to canals, waterways and rivers. The swale liner is installed also, reducing the need of excavating the swale.

What can I do to help?

Residential Swale LinerHelp us maintain the Stormwater Drainage System by keeping the flow line in your swale free from obstructions by cleaning the plastic swale liner. Driveway culverts and concrete repairs are the homeowner’s responsibility to maintain. Remember, the dumping of grass clippings and other debris into the drainage system, swales and Drainage Right-of-Ways cause erosion and failure of the entire system.

Maintenance of the swale system is vital to the city’s drainage system. Proper maintenance of our swales protects our streets from damage and our homes from possible flooding. Please report any drainage system failures you see to our Customer Service Division at (772) 871-5100. These reports may include washouts, culvert failures and swale obstructions.
