DGC offers annual maintenance contracts tailored to your specific situation and requirements which usually includes scheduled maintenance services. As in the case of inspections, our contract can be modified as you prefer. Regardless of who does the specific work, our program makes sure the facility is being maintained properly.

Our typical maintenance contracts will address the following items:

Mowing
Most maintenance requirements require grass or groundcover be mowed at least two time every year.

Maintain Vegetative Cover
We monitor grass and ground cover and will routinely seed or treat bare areas as needed.

Tree and Brush Removal
Woody growth cannot be allowed to grow on fill embankments or close to riser structures. A proper mowing schedule will keep trees and brush from becoming established, however, some areas may not be accessible for mowing equipment. We make sure all areas are maintained to ensure long-term embankment stability and regulatory compliance.

Trash and Debris Removal
Litter and debris gets washed away in the rain, but guess where it ends up... If removed on a consistent basis, it shouldn't become a major problem or expense.

Removal of Sediments
Sediments can contain many pollutants and one of the primary purposes of stormwater management is to remove them before they can reach streams. Maintenance visits allow us to monitor the volume of sediments so we can clean them out of the facility before they become a major issue.

Risers, Pipes and Other Appertances
These elements are crucial to the function and safety of stormwater management facilities. They regulate and convey flows from storm events - sometimes at significant volumes and flow rates. The most common problem that can lead to major problems during large storms is blockage.

We recommend clear signage for all surface facilities to ensure the public is aware of potential danger when water is impounded during and after storm events. In residential areas, we recommend and can facilitate public awareness campaigns to make sure the residents, especially children, are aware of potential dangers.
