RainSava rainwater harvesting systems

Overview

Nature delivers a supply of soft rainwater directly to your property. Houses and business' generally have built-in collection devices (roof, gutters, downpipes) delivering rainwater to ground level. Diverting this rainwater through a filter to a rainwater storage tank makes it readily available for many uses.

RainSava rainwater harvesting and rainwater collection systems offer a sustainable, eco-friendly alternative to a municipal or well water supply for non-potable use in home, commercial and industrial properties. Rainwater harvesting saves money, reduces surface water from your property and may offer a storm water management solution.

Rainwater harvesting and rainwater collection systems are designed to provide an alternative to the use of pure drinking water for non-potable use. Anua provides complete rainwater harvesting and rainwater collection systems as well as individual components to capture and use rainwater that falls on your roof.

How it works

1. Any rainwater entering the tank should be as clean as possible. This is accomplished using rainwater harvesting filters.
    
2. Rainwater that enters the tank must be “calmed.” Rather than openly discharge into the rainwater collection tank, rainwater is directed to the bottom where it can gently percolate upwards, below the minimum water level. It is important this bottom sediment is not disturbed. Over time it will form a beneficial biological layer that assists in maintaining rainwater quality.
    
3. The rainwater collection tank is designed to overflow periodically, at least twice per year, so any floating debris can be removed by the skimming effect of the overflow device. For this reason the volume of the rainwater collection tank is carefully calculated to ensure that overflow conditions occur.
    
4. Rainwater should be extracted from the cleanest part of the tank; just below the surface. This is achieved by the use of a fixed or floating suction filter. This ensures that the rainwater extracted avoids both floating debris and bottom sediments.
