Standard SSI will provide efficient removal of pollutant particles (.50
"
inch solids/sieve size 200 sediment) for the majority of site conditions.
WQTV* is the Water Quality Treatment Volume ("FirstFlush") or the first .50" of rain water runoff from the drainage area. 24" dia. manways
are standard; 30", 36", and large rectangular EZ-Access manways are available.
