Maximum quantity available reached.

If you're considering rainwater harvesting on a commercial scale a Level 3 Rainwater Harvesting Calculation may be suitable.  Our level 2 analysis is available for free by clicking this link.

For larger schemes where significant economic benefits might be realised or where there is a temporal variation in demand it is suggested that continuous rainfall time series (or simulation modelling) should be used to address this variability in order to optimise the design in accordance with BS 8515. 

The output is a one page pdf document containing the : 

  • optimised storage requirements
  • reduction in mains water usage
  • proportion of time the tank overflows
  • budget cost benefit analysis 
  • Carbon offset

What we require: 

  • Site Location/ Site plans/Elevations/Drainage Plans​
  • Usable contributing drainage roof area to the rainwater tank 
  • type of usage for which rainwater will be used 
  • existing water usage data if available 
  • proposed demand from rainwater tank e.g 1m3/day 
  • typical occupancy if relevant to proposed rainwater usage 
  • site/roof/drainage plans (and WC locations) 
  • whether a location for a loft/header tank  tank is available ​​​

Simply email technical with the above details with your order number as the subject line. 

The pdf will be delivered to the email address you have registered with. 

If you are combining attenuation with rainwater harvesting please contact us first. 

Allow 10 working days for the output to be delivered.
