Rainstream Home XL offers an alternative rainwater re-use solution for home and garden use. Where deeper burial depths are required (often a characteristic of communal storage systems) this structured wall tank is capable of withstanding water pressure up to 6m burial depths or 0.6 bar. Far exceeding the normal requirements of rainwater re-use systems. Still a relatively shallow excavation on individual on plot installations; the twin turrets allow easy access to the fully submersed pump and in-line filters which offer the choice of configuring a direct (pressurised) system or an in-direct (gravity fed) system.

The Rainstream Home XL System

The structured wall design of Rainstream Home XL has created a system that is unique in its ability to withstand a high water table. The key benefit of Rainstream Home XL is that it will never need a concrete surround in non-loaded applications, even in cases of a high water table. All that is needed is a concrete base which the tanks are strapped to. It provides a simple solution to the complex problem of rising water tables and changing weather patterns. As most systems are installed during the summer months, when water tables are at their lowest, the resulting winter rising water table is often not taken into account. Some systems are not designed to be installed within the water table and are unable to withstand the hydrostatic pressures, resulting in their collapse. Rainstream Home XL has been designed by Civil Engineers to withstand these hydrostatic pressures. Further testing has taken place proving the tank's capability to withstand water pressure at a burial depth of up to 6 metres or 0.6 bar, far beyond the pressures the tank is likely to face. The range of tank sizes offered by Polypipe has been researched and designed to meet the exact requirements of the UK market, based on research into the national average household water use and the most up-to-date MET office data. Rainstream Home XL tanks allow the homeowner to meet their exact requirements and therefore provide the most cost-effective and efficient solution in the market, without the need to over-specify and incur disproportionate purchasing and installation costs. If increased capacity is needed, Rainstream Home XL offers a wide range of tank sizes to ensure rainwater collection is maximised effectively.

Gravity-fed (indirect) and pressurised (direct) systems

Polypipe offer both gravity-fed and pressurised systems. Within a gravity fed system water is pumped from the Rainstream Tank to a header tank in the loft. The water is then fed to each appliance by gravity. Pressurised system uses a pump to feed water directly to the appliance or appliances on demand.
