Below Ground Potable Water Collection 4×1800 USG Design

Description

Our FREE Below Ground Potable Water Collection 7400 USG, 4×1800 USG Design

This potable water collection system is designed as a primary source of water for potable purposes, such as drinking, bathing, toilets, and laundry. With a backup water source of hauled bulk potable water if the rainwater tank is empty. The system will provide water for water uses Tier: R4 Potable Drinking Water

Roof

The system will be harvesting rain from one building. The roof is made of fibreglass shingles.

Gutter, Downpipes, and Conveyance Piping

The gutters, downpipes, and conveyance piping are sized based on specifications from the designs.

Pre-Filter

The system will require one (1) pre-filter. This pre-filter operates as both a first flush diverter and prefilter, with a filter mesh size of 320 microns. The full cross-section (pipe diameter) of the rainwater drainage system remains continuously open, and there are no reductions in the cross-section of this appliance in which dirt or water can collect.

Rainwater Tank / Cistern

This system will provide a total of 7,440 USG of rainwater storage, with a total of four (4) underground rainwater tanks, made of polyethylene. Each tank is 1860 USG. Tank connections, valves, and fittings above the frost zone must be wrapped in heat cable to protect these components from freezing when installing. The rainwater tank is designed to provide safe storage of rainwater, which improves water quality because of its design and function. The calming inlet prevents agitation of settled fine dust, the skimming overflow removes floating particles, and the floating filter ensures water is drawn into the pump from approximately 150 mm (6.0″) below the surface of the water.

Water Pumping and Treatment System

Cleanflo determined the water demand to be 10 GPM @ 60 PSI. This will be pumped by a submersible multi-stage booster pump powered by VFD. The treatment will be three stages to ensure water is safe and there is no staining on fixtures. Stage one is a sediment filter of approximately 15 microns, which is reusable. Stage two is a 10-micron carbon filter. Stage three is a 1-micron absolute sediment filter. Stage four is ultraviolet sanitation.

Water Quality and Treatment

Cleanflo designed this system to produce water that is safe for CSA B805 R4 uses; namely, drinking, bathing, cooking, toilet, and laundry.
