Service and Maintenance

Oldcastle Infrastructure Service and Maintenance (OSM)

If you have stormwater BMPs on your property, it is mandatory to service them to remain compliant with Federal, state, and local regulations. Regular maintenance ensures optimal system performance, compliance, and the removal of harmful contaminants from urban runoff prior to entry into our water resources.

Avoid Unnecessary and Costly Fines

Owners of stormwater BMPs that meet the EPA Clean Water Act’s criterion of Best Available Technology (BAT) for prevention of pollutions from stormwater runoff are not immune to fines. The most sophisticated equipment is only as good as the associated maintenance program.

Certificate of Compliance

Upon completion of each maintenance service, OSM will issue a Certificate of Compliance to the landowner or manager for their records. This provides notice to the responsible person that all systems are maintained and performing per specifications.
