Making the Case for High Flow Biofiltration Systems

We all know the history of Low Impact Development (LID). Developed in Prince George's County, Maryland in the early '90s, adopted throughout the Chesapeake Bay, gradually adopted in the Northwest and the Great Lakes and now picking up steam and moving coast to coast; it's an important part of the upcoming post construction rulemaking and TMDL responses; and its rightfully recognized as a key piece to solving our water quality, volume and velocity woes and to meeting our sustainable development goals.

Analyzing Biofiltration Media Performance for Stormwater Solutions

Posted by David Batts on Fri, Feb 03, 2012 @ 02:32 PM

The short and long term performance of engineered media specified for use in biofiltration systems is something that must be taken into account when utilizing bioretention as the primary solution for stormwater management and stormwater quality. Many times only the short term infiltration rates of a biofiltration media are considered as instead of what actually takes place over time. Another common mistake is to assume that results attained with one batch of the biofiltration media will be the same results with the next batch using identical specifications. Although biofiltration medias are “man-made” they are still a natural system that are always evolving.  Plant type, the biological health of the system, the weather patterns for a given time period, and many other variables create this discrepancy among the different batches of biofiltration media.

Rainwater Harvesting As A StormWater Solution

Posted by David Batts on Mon, Dec 05, 2011 @ 10:27 AM

With record droughts across the country and rising potable water costs, water harvesting is becoming a more sought after amenity on residential, commercial, and institutional buildings. One of the biggest factors to consider with water harvesting is the return on your investment. This often time become a battle between water supply and water demand.
