New CPD explores rainwater harvesting issues

A CPD explaining the issues around rainwater harvesting and the options available for specifiers and users has been launched by Graf UK.

The water management specialist said the 55-minute presentation covers topics extending from the fundamentals (what is rainwater harvesting and why is it required) to key regulations and issues, via a mix of ‘live’ presentation and videos.

The CPD shows just how little of the earth’s water is available for use by the global population and forecasts a global rainwater crisis in the next 25 years, with water shortages in the UK by 2040.

It advises on what rainwater can and cannot be used for, health and safety considerations for the installation of underground tanks, and how harvesting systems can be combined with storage for SUDS and stormwater management.

The resource also advises on options for garden, domestic and commercial applications, how an underground tank is typically installed, and how it works.

A guide to sizing rainwater harvesting systems according to BS EN 16941-1:2018 and criteria such as expected yield and ground conditions is also featured, along with options for modular add-ons such as covers, filters and technical packages.
