Every Corcoran Precast Rainwater Harvesting system is equipped with the following:
Storage Tank – The Rainwater Harvesting system includes a Corcoran Precast concrete tank, which has several advantages over plastic systems. There are a variety of tank sizes available, and it is important that the tank size chosen is suitable for your house. Our engineers will design an appropriate system considering the roof size, rainfall, rainwater application and occupancy.
Leaf Filter – Rainwater will collect leafs and other solids from the roof and gutter system which need to be removed. A leaf filter is fitted on the inlet pipe; this collects all gross solids preventing them from contaminating the stored water.
Calmed inlet – Dissolved solids such as sand and grit will be carried into the system, these pass through the leaf filter unaffected, however, they will settle to the bottom of the tank, hence not affecting the quality of the outflow. To prevent the inrush of water from disturbing these solids a calmed inlet is installed on the inlet pipe.
Submersible pump – Rainwater is pumped from the tank into the house by a pump positioned off the floor of the tank to prevent the settled dissolved solids from contaminating the house supply.
