The maintenance process begins with an Initial Inspection of the drywells or other drainage structure. During this inspection an assessment of the drywell or drainage structure is performed. The amount of accumulated silt & debris needing removal is estimated along with any associated repairs needed to internal piping, concrete, screens, or grate covers. This assessment is recorded in an inspection report that is provided to the customer. A color coded site map showing all the drywell and drainage structure locations is also provided to the customer for future maintenance and reference purposes. Finally, the customer is provided with a cost proposal for all cleaning & repairs needed.

After the initial inspection and approval of the cost proposal, StormWater Pros performs the Cleaning/Maintenance Work with use of specialized machinery and trained staff. Silt and debris removal is performed by the use of hydrovactor truck that utilizes high water pressure and suction power for the removal. All settling chambers are properly cleaned and any associated or attached storm drain pipes are cleaned using a jet rod attached to the hydrovactor truck. All silt & debris removed is properly disposed of off-site. Any hazardous materials encountered are disposed of at a properly permitted site. Drywell maintenance also includes replacement of the geotextile fabric and oil absorbent pillows. The geotextile fabric is located at the bottom of the settling chamber and protects the drywell gravel pack. Drywell and storm structure grates and covers are properly replaced and secured when the cleaning/maintenance services are complete.
