Expert design service

We provide a complete in-house design service, including site survey, that ensures all aspects of your application are considered when specifying your rainwater harvesting system.

This takes into account the following:

  • Storage capacity (accounting for regional rainfall statistics and roof area)
  • Incoming demand (occupancy levels, appliances to be supplied etc.)
  • Filtration (eg leaf filters, ultraviolet)
  • Tank connections (pipework sizes and positioning)
  • Overflow arrangements (drain, soakaway including backflow protection)
  • Backflow protection (isolation of mains water from rainwater, via air gap, conforming with BS 8515)
  • Pump selection (pumping distance and configuration)
