Effective stormwater management protects your property from flooding, erosion, and costly repairs. We install and repair catch basins, drainage systems, and swales designed for commercial and industrial sites. Promain delivers dependable stormwater solutions that keep your site safe and compliant.

Catch Basin Installation
Catch basins are an essential part of a commercial stormwater management system. To install a new system, a team of Promain experts will drop a large concrete basin below the parking surface and connect sloped pipes for drainage. Catch basins filter trash and debris from the rainwater that will continue through the system to be processed at a water treatment facility.
Catch Basin Repair
Just like asphalt, catch basins require regular maintenance to be reliable and control damage. If your catch basin is in need of maintenance or repairs, Promain is able to restore function to keep your stormwater system managing rainfall properly. Regularly scheduled maintenance prevents flooding and keeps toxic waste left behind by vehicles out of the community water supply.
Watermain & Line Repair
A watermain is an underground pipe that connects your property to the city plumbing system that sends out waste water and receives clean drinking water. Seasonal weather changes cause the watermain and surrounding lines to contract and expand leading to leaky and worn pipes. Leaks and cracks in the pipe can disrupt water pressure, spike water bills and flood surrounding properties. Promain is available 27/4 and has a variety of solutions to investigate and determine the best solution, including hydro excavation, line jetting and camera inspection services.

Swale Installation
A swale is an environmentally friendly, landscaped channel designed to collect stormwater and runoff from roads, highways and parking lots. Large filter rocks and carefully selected local vegetation create a visually appealing filtration system that protects local waterways and minimizes standing water.
