Water, or the lack of water, is becoming an ever increasing issue and needs to be addressed as a matter of urgency. Climate change, over extraction of water resources and population growth are largely to blame for the current and future areas of water stress. Filtered rainwater can be used to flush the toilet, in washing machines and in the garden. An IRM™ rainwater harvesting system from GEP makes this possible; in a safe and reliable manner. Rainwater harvesting gives great benefits with little effort;

  • Saving mains water, more than 50%
  • Flood reduction due to storage rainwater tanks and usage
  • Complies with BREEAM and KIWA

In situations with long horizontal drainage pipes and large portions of land below sewage level a lot of pumps are required to transport the rainwater and waste water from one point to the other. This also means that often pump systems are required to pump the waste water to the sewerage system. Prior to transporting the waste water it first needs to be collected in a tank or shaft. GEP has a wide assortment of pumps for both waste water and rainwater. ; 

  • Pump pits for rainwater, stormwater and waste water
  • Pump shafts for rainwater, stormwater and waste water

A break tank is a reservoir which is placed between the water gauge and one or more connection point. Break tanks are also known as disconnection tanks. Such break tanks are applied where a where an interruption of the water supply is necessary or mandatory. The most important reason for using a disconnection tank is the prevention of contamination of the water network due to the presence of dirt particles in case of back flow of the water; 

  • Breaktanks, typ AA and AB disconnection, according EN1717
  • Tanks for drinking water
  • UV Filters for disinfection of water

The grey water from the shower, sink and bath are drained to the storage tank. The light polluted grey water is first biologically cleaned in the storage tank. The water is actively cleaned by reducing organic impurities with the use of a computer controlled ventilation. The biologically cleaned water is then forced through the membrame filter after which it is stored in the clean water tank. From the clean water tank the water is pumped to the secundairy water network by a pump, according to demand. This water network is connected to the washing machine, garden taps, urinals and toilets. If the clean water tank is running low on water, it will be filled from the rainwater tank. If this rainwater tank is also running low, or is not present, than the system automatically switches to drinking water; 

  • Grey water, safe water
  • Grey water, recycle water
  • Grey water, use your water twice
