Commercial RainCycle®

RainCycle Commercial rain harvesting system offers ground installation for the collection, filtration and storage of rainwater for use within commercial and larger developments. The commercial system can provide storage for up to 90,000 litres within a single chamber and are designed specifically for each scheme to meet requirements.

Please contact our sales team for further information and advice.

The RainCycle has economic benefits for larger schemes where pooled water resources can reduce water costs.


  • Community housing
  • Multiple dwellings
  • Flat / Offices / Workshops
  • Industrial processes
  • Community centres
  • Supermarkets
  • Schools
  • Hospitals


The system needs minimal maintenance, but we would suggest that your RainCycle is inspected by our Service Engineers at least once per year to ensure that all filters are clean and clear, and sediment levels are acceptable to ensure optimum performance.

A Service Agreement Scheme is available, contact us for further information.


Once the electricity supply and liquid connections are made the RainCycle system is ready to be commissioned. Our engineers can undertake a full check of the installation, ensuring that it is safe and to specification. Checks are carried out to verify the RainCycle system's operational sequence and its overall function.

A full installation and commissioning report is provided to the site representatives.

Health and Safety

T-T attaches the highest priority to Health and Safety issues.

All Service Engineers work in teams of two and are fully qualified for:

- Confined Space Weorking

- First Aid

- 17th Edition of IEE Wiring Regulations

Where multiple dwellings are drawing off one RainCycle we would recommend that a metering system is introduced.

Sizing of the RainCycle

The amount of water available for use is dependant on the rain water collection area, which will normally be from the roof, and local rain fall, which varies from area to area. Usage of water needs to be considered; for normal domestic use, we take that a nominal amount of total water used can be rainwater and will depend on the usage data you provide to us. 

Normally this will vary for commercial property and where residents may want to use more water for the garden.

Considerations for selecting a RainCycle

The RainCycle can be happily introduced into most schemes as part of a new build or as a retrofit, but care should be taken to understand the limitations and maintenance requirements.

a. Small schemes will have an extended payback period

b. Recovered rainwater is not suitable for human consumption

c. All taps and pipework used to convey rainwater must be clearly labelled

d. Systems incorporating a back-up from the mains water supply require a type AA or AB backflow prevention device

    - A type AA air gap conforming to EN 13076:2003 to prevent pollution by backflow of potable water - unrestricted air gap

    - A type AB air gap conforming to EN 13077:2008 to prevent pollution by backflow of potable water - air gap with non-circular overflow

e. Gutters used for collecting the rain water should be checked and cleaned regularly. Avoid area where large amounts of bird or animal dropping are likely

f. The RainCycle system should be checked by the user periodically to ensure that the system is clean and that it operates correctly

g. Every 12 months the RainCycle system should be inspected and serviced by a competent engineer. T-T offer a reassuring and economical Service Agreement Scheme

h. Care should be taken when selecting roofs for rainwater collection. Only use roofs that are in a good state of repair and away from areas of heavy leaf deposits. Avoid using roofs covered in asbestos, old steel corrugation that is rusty and roofs with mastic covering or repairs, as the quality of water collected will be impaired.
