Tag: tmdl

Total Maximum Daily Load (TMDL) is a regulatory term in the U.S. Clean Water Act, describing a value of the maximum amount of a pollutant that a body of water can receive while still meeting water quality standards. Alternatively, TMDL is an allocation of that water pollutant deemed acceptable to the subject receiving waters.

Urban stormwater runoff is one of the leading causes of water pollution because it carries pollutants such as oil, grease, pesticides, fertilizer, animal waste, trash, debris, and other substances through storm drains and into lakes, rivers, and other bodies of water.

EPA protects water quality by regulating municipal separate storm sewer systems (MS4s) to reduce the pollutants that stormwater runoff carries into storm sewers. Nonpoint source pollutants from impervious surfaces such as oil, grease (hydrocarbons), heavy metals from vehicles and atmospheric deposition, fertilizers, pesticides, and sediments are commonly picked up by

Stormwater Monitoring

The most dramatic and identifying characteristic of water is that it is always moving. Even so-called standing water is never completely static; it’s either being drawn by gravity to seep down into the earth or being agitated by warmth at the surface to rise into the air as a vapor.

PAVEDRAIN LLC
The PaveDrain system is a patented, permeable paving surface designed with the joints between the blocks left open for an unprecedented infiltration rate (i.e., no rocks). Maintenance is accomplished with conventional street vacuuming equipment or the PaveDrain Vac Head. PaveDrain is ADA Compliant, HS-25 load rated, manufactured throughout the

In recent years, the focus on stormwater mitigation in Surfside Beach, SC, has been on water quality, notes John Adair, public works director.

“The topography along the coast is very flat, so getting the water to go toward the ocean is always a challenge because you might only have very slight

Asset Management

Asset Management

Asset management (AM) is a popular management strategy for maintaining the level of service for water and wastewater systems. These systems have clearly defined services and objectives and have been tested and regulated for much longer than stormwater systems. Compared to wastewater, stormwater less frequently receives direct treatment to remove
