Major Components Pre-Filter Tank Pump & Treatment

Why Pre-Filtering? Keep leaves and large debris out of tank – ASPE 1200 Microns, 0.05”

Self Cleaning Pre-Filters Vortex Cascade Hydraulic Jump Keep leaves and large debris out of tank – ASPE 1200 Microns, 0.05”

Pre-Filter Sizing Manufacturer Guidelines are “Guidelines” Look at Consequence of Undersizing Pipe runs affect flow Size for capture and not for heavy rain events – Emergency overflows

Additional Filtration Floating Extractor Overflow Siphon Calming Inlet

Typical Capture Set Up

Types Of Collection Tanks Above Ground Below Ground Steel Plastic Fiberglass Concrete

Above Ground Tank Types - Metal, Lined 3, ,000 Gal Paintable Cladding Stone, Wood

Above Ground Tanks Advantages Less Expensive Easier Maintenance Marketing Educational No Groundwater Issue Disadvantages Footprint Temperature Aesthetics (maybe)
