SIR irrigation stations consist of both smooth and corrugated underground tanks. They are fitted with a PVC inlet stilling pipe and overflow pipe, PP (polypropylene) outlet pipe and connectors, submersible electric pump, polyethylene (PE) delivery pipe, clapet type check valve, pump lift chain and electronic control pressure switch 

USE: rainwater harvesting and re-use for irrigation purposes, feeding automatic (telescopic irrigators, sprinklers, sprays, etc…) or manual systems (taps, fountains,…). 

OPERATION: the system allows storage and delivery of between 1000 and 36000 litres of water. Rainwater runoff from roofs (or other exposed surfaces) enters the storage tank through the inlet pipe, after flowing through a filtering system (recommended). When the tank is full, any excess water is sent to the main drainage system through the overflow pipe. A submersible electric pump is installed in the tank. An electronic control pressure switch controls the pump, allowing the stored water to be used.
