Rainwater Harvesting Limited wins much of its
business in competitive bids. We have the highest quality products,
keen pricing policies, and informative quotation documents. No job
is too small (a tank, filter and pump for a small home) or too big
(50 homes in one development, a hospital or a full size sports
centre). We are typically supplying system from 2,700 litres for a
small home to 140,000 for a shopping centre
Specifications needed
You have initial architects' plans and you'd like to have Rainwater Harvesting Limited write a complete specification. In addition to the details requested in the form below we would be grateful to be able to see ground plans including invert levels in hardcopy by mail or in pdf form by email. In all probability we will contact you further to discuss your requirements and your preferences in respect of tank type, tank location, direct or gravity feed, and mains backup options.
Tank size calculation and rainwater harvesting options
We are always very keen to do the best job for you and this includes checking the storage tank size against the new British standard for rainwater harvesting BS 8515/2009. We will provide you with the Excel spreadsheet showing the data from which the tank size is drawn, and you can use it to make your own checks against, for example, the Code for Sustainable Homes and the BREEAM calculations. Please fill out the form below or email us the same information. You can also download the tank size calculator to make your own assessment.
Quote to your specifications
If the rainwater system including sizes and
options has already been specified, please send us the full details.
If the tank size given is not one of our standard sizes we will

Please let us have some information so we can respond to your enquiry.
