Storm Water Leaching

Dealing with run-off water correctly is of extreme importance, besides preventing flooding; storm water run-off is a leading cause of pollution in our lakes streams and coastal waters.

Benefits of using Excav are:

  • Geologist with knowledge of soils permeability
  • Large and small capability – whatever you need, one size does not fit all
  • Compaction equipment – proper compaction ensures backfilled areas will not settle
  • Aware of local jurisdiction and codes, best available technology for applications

Storm water run off or Non Point source pollution is the leading cause of degradation in our lakes streams and coastal waters. This pollution has a direct effect on human health by degrading food sources such as fish and shellfish as well as making our recreational areas unhealthy.

From simple, cost effective measures such as vegetated swales to high end high volume radiative in-pipe filters we can help you meet your storm-water run off demand while preserving the environment.

At Excav we prefer to work with environmentally friendly landscapes. Not only will this save money now, but maintenance is less intensive and you can feel good about it. Ask us for some ideas on environmentally friendly landscape and drainage ideas.

If you have a design, great, we would like to provide a quote for your storm water drainage system installation.

If you would like to consider options on a grading and drainage plan, please call us for a review of your site and proposals on how to develop or improve your project.
