Expanded Shale, Clay and Slate (ESCS) ceramic lightweight aggregate is providing new, consistent and cost effective options to address environmental concerns about the threat of storm water to our clean water supply. ESCS provides design flexibility for storm water management programs in meeting this environmental crisis.
ESCS offers low-maintenance solutions that meet existing and proposed government regulations without the use of chemicals, specialized equipment or major facility upgrades. On-site storm water management contributes toward LEED green building certification credit. The use of ESCS in such designs offers improved performance and longevity.
ESCS adds a new dimension to the medium contained in storm water treatment units. As a replacement for sand, ESCS raises the bar for storm water treatment performance to new heights. The effectiveness of this new application is currently being tested by treatment unit manufacturers across the country.
As a filter medium, ESCS is very durable, and coupled with its porous structure and increased surface area, it is an exceptional filtering material for metalloids, suspended solids, oil and grease. ESCS has the long-term ability to absorb nutrients and maintain hydraulic flow to ensure that water treatment is effective and sustainable. ESCS is the clear choice for storm water management.
