System hydraulics refers to how water flows through a stormwater filtration system. The following three steps should be part of the hydraulics evaluation process:

The City of Los Angeles Bureau of Sanitation received the Outstanding Stormwater Best Management Practice (BMP) Implementation Award for its Garvanza Park Stormwater BMP Project from the California Stormwater Quality Association (CASQA). 

These are the top 8 questions asked about Rainwater Harvesting Treatment after Part 1 of our Rainwater Harvesting Webinar Series: Rainwater Harvesting as a Runoff Reduction tool. You'll find questions like...

With harvesting off of parking areas, how do you handle oil and grease?
How would the engineer develop the mechanical control panel for these systems? Is a turnkey solution provided by the product vendor?

An increasing challenge that we see with our customers is balancing water quality with water quantity. Conventional design would be to use an in ground detention pond. But, if this is not an option, whether the owner does not want the aesthetics of a pond, the land needs to be used for parking, or you have a layer of clay soil that makes traditional infiltration not possible, consider using a perforated CMP manhole or an infiltration well (drywell).

In this video, Cory Carlson, detention product manager for Contech, describes the advantages of these two systems in balancing your water quality and water quantity needs.

This short video explains how rainwater harvesting is a logical and feasible approach to managing stormwater runoff using example usage for a typical commercial office building.

With LID, not all solutions are created equal. There is a hierarchy in the regulations for what is the preferred technology. So it’s not so much is it approved or not approved… there are certain preferred technologies that must be considered first, and if that doesn’t work, you consider the next option in preference. This is a huge difference in conventional stormwater regulations, which says technologies must be approved by state of local jurisdictions – and then everything is on a level playing field.
