Residential emergency backup water supply
Raincell Backup water system

Our company design and install small backup water systems which we install as a separate system or combine it with a rainwater harvesting system.

It can operate on two principles.

  1. A standby principle. A backup water supply tank is installed with a pressure pump system on standby. The moment the municipal supply is interrupted  and the pressure drops, the system automatically starts up and supplies the house or business with water until the municipal water supply has been restored. It is recommended that the water in this system is used once a month and topped up with fresh water in order t o prevent the water form going stale.
  2. Continuous water pressure boost system. Due to the ongoing water supply problems many municipalities have reduced the water supply pressure to households. This system has an intermediate tank which is supplied form the low pressure  municipal supply. From the tank we install a booster pump system that boost the pressure to the property with our special energy efficient booster system. As water is used from the tank it is filled again by the low pressure municipal water supply

Only the best components are used in our back-up systems to ensure reliability and efficiency of operation. Our systems are installed with external or internal submersible Grundfos® multistage centrifugal pump coupled to a pressure tank and pump controller. The pressure tank increases the longevity of the pump and reduces energy consumption by reducing the number of pump starts required. The pump controller is designed to work in conjunction with the pressure tank and provides run dry protection for the pump. It has an adjustable cut-in pressure and a precise cut-out mechanism to ensure the pump works optimally for any household, from single story dwellings to multistory facilities.

Backup water pump

Peak water demand and pressure requirements will be calculated for your property based on the number of plumbing fixtures (Taps, showers, toilets, basins, etc.) installed, and a correctly sized pump with the optimum performance characteristics will be selected, to ensure that your facility always has adequate water pressure, while using the least amount of electricity.

A tank, or tanks will be selected based on the available space and your water requirements. A tank will be sized to meet three to five days usage, or as you see fit. Our systems come with a 1 year guarantee against installation or component defects.
We keep a limited stock of Raincell tanks and can offer a competitive

It is recommended that at a minimum reserve capacity of 2-3 days be installed. This system is perfect for household and companies where water supply is critical, like the hospitality industry where guest cannot be inconvenienced due to the lack of water while on holiday or business.
