Freerain domestic rainwater harvesting recycling systems

With a Freerain rainwater harvesting recycling system, a typical household can expect to save around 50% of their mains water needs (see usage chart). Secondly the inclusion of a rainwater system can help with water related issues during the planning process, including meeting the requirements of the Code for Sustainable Homes.

The Freerain domestic rainwater harvesting systems come complete with mains water top-ups. If you are interested in system for the garden only, please click the garden systems from the menu to the left.

Freerain's parent group, Gusto Group is an experienced "eco-developer" and therefore, the Freerain rainwater harvesting systems have been designed and developed over the last decade with true end-user knowledge and experience. This wealth of knowledge was an overriding factor in the design of systems, which are straightforward to install, minimal end-user maintenance and above all offer a high level of reliability.

At Freerain we can supple either direct pressure or header tank rainwater harvesting systems and our sales team will be able to advise you on the best approach to suit your project's requirements.

Domestic rainwater harvesting systems overview of a typical system

	Large stocks for fast shipping		Pre-fitted calmed inlet
	Sizes from 1800 litres to 10,000 litres		Low excavation depths

Tank dimensions by volume
Litres	Dimensions (WLH) mm	Litres	Dimensions (WLH) mm
1,800	1260 x 2080 x 1250	5,200	2700 x 2700 x 1250
2,600	1260 x 2880 x 1250	6,800	2700 x 3420 x 1250
3,400	1260 x 3680 x 1250	8,400	2700 x 3970 x 1250
4,400	1260 x 4510 x 1250	10,000	2700 x 4770 x 1250

Filter - key features

	Pre-installed in tank		550 micron (lower stage)
	Suitable for roofs up to 215M2		Steep angle to wash dirt away rapidly
	Low maintenance		No consumable parts
	Two-staged filtration		Standard size connections

Control system (direct) - key features

A direct pressure system is perhaps the simplest form of domestic rainwater harvesting. Rainwater is delivered directly to the point of use via the submersible pump in the storage tank. Should the storage tank become low, then mains water is allowed back into the tank, where the level is held around 5%. This leaves 95% of the capacity to take advantage of the next rainfall.

		Compact in size		Pressure vessel
		Automatic mains water top-up		WRAS certified & BS8515 compliant
		Pressure gauge		Class AA air-gap
		Submersible pump 4 bar, 4,000L/hr max

Control system (indirect/header tank) - key features

A gravity fed rainwater harvesting system involves the use of a secondary storage tank, which is usually mounted in the loft of a property. When mains water top up is required (due to the main storage tank running low) it enters the header tank and not the underground tank. Our patent-pending mechanical control system, allows for several WC flushes (or a washing machine cycle) before the pump engages, thus saving pump energy and wear and tear. For customers wishing to use water outside, pump pressure is available by teeing off on the route up to the header tank.

		Minimal controls		Class AB air-gap
		Automatic mainswater top-up		Patent pending mechanical delay action.
		91 Litre header tank 460mm X 613mm x 450mm (WLH)		Simple fuse spur with rainwater indicator
		In-line strainer		No electronics to the header tank.
		Submersible pump 4 bar, 4,000L/hr max

Quotations and Pricing

Typical systems start from around £1525 (list) for the 1800 litre version (either direct or header tank). In order to fully understand your requirements and ensure that you are buying exactly what you need, please contact us for a quotation. If you have architectural drawings, we are happy to review these and make recommendations regarding the best location for the storage tank and controls.

Notes

A full technical pack (project specific) is issued with every quotation as the above description is a typical systems and we tailor our offering to your specific requirements.

Submersible pumps eliminate bulky controls, noise and are more efficient. Some systems often use suction pumps, which are prone to losing prime and require much larger equipment installed in the property. The use of a small pressure vessel aids the overall performance of the rainwater harvesting system and further prolongs the life of the pump.

Installation

Our rainwater harvesting systems have been carefully designed with ease of installation in mind and therefore, this work can be completed by regular on-site trades. Our rainwater harvesting tanks have been designed to have the a shallow excavation, helping to keep this installation as cost effective as possible. Very shallow tanks found elsewhere are often too shallow and are not compatible with many drainage plans, resulting in the costly additional purchase of raising pieces or adoptions on-site.

Variations, optional extras, upgrades and specialist components

The above systems are "typical" direct pressure and header tank domestic systems. In addition to these systems we can offer a wide selection of variations to meet specific requirements.

Please contact us by telephone or e-mail to discuss your requirements.
