Tag: MS4

Polluted stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (MS4s), from which it is often discharged untreated into local waterbodies. To prevent harmful pollutants from being washed or dumped into an MS4, operators must obtain a NPDES permit and develop a stormwater management program.

Stormwater Goes to School

Not too long ago, there were only two colleges in the United States where one could learn about stormwater management, notes Brant Keller, public works director for Griffin, GA.

A Five-Year Study of IDDE Data

Pierce County’s Surface Water Management (SWM) division is charged with maintaining both the natural surface water systems and the stormwater collection and conveyance infrastructure within its unincorporated 1,800-square-mile service area (population 380,000). These areas include an impressive variability in landscapes: from glacial streams of Mt. Rainier to fertile farmlands of

Foliar Rainfall Retention

Foliar Rainfall Retention

Trees and forest systems play an important role in the water cycle by intercepting rainfall and regulating water flow to the soil for more efficient stormwater infiltration. Traditional urban development practices have reduced the function of these systems by eliminating the vertical structure (tree canopy cover), removing existing ground cover

Underground Stormwater Storage Case Studies

Underground Stormwater Storage Case Studies

Underground retention and detention systems continue to increase in popularity as urban and suburban infill prompts careful consideration of proposed land uses on high-value real estate. Placing stormwater management underground frees up space for higher value land uses and greater return on investment. Additionally, trends toward water awareness and reclamation,

In the 1940s, two former music hall entertainers, Marcel and Nelly Tilloy, purchased an estate in France’s Rhône ­Valley, and by 1952 they had created Relais and Châteaux, with eight hotels and restaurants between Paris and the French Riviera. Today, the association has more than 520 partners around the world.
