PATENT Low Cost Rainwater Harvesting System For Housing, Schools & Commercial Buildings 386445 TITLE Low Cost Rainwater Harvesting System for Housing, Schools & Commercial Buildings FIELD OF T1119 INVENTION The Low Cost Rainwater Harvesting System relates to the process of capturing and storing rain water and using this stored water for use in WCs, washing machines, car washing and outside yard tap and also to help conserve resources that would have been wasted otherwise.

Over 65% of all mains water is wasted on uses that do not require drinking quality water. Rainwater is also better for your garden and growing vegetables because unlike tap water it does not contain any chemicals due to the absence of chlorine.

BACKGROUND TO THE INVENTION The system provides the benefits of up to 65% savings for residential I commercial & public buildings; huge reduction in water bills; provides oontrol over water supply and adds value to your property.

Our rainwater collecting and storage system is simple and easy to understand, install and operate.

Financial benefits for you — the system is less expensive, the system has low running costs and low maintenance.

The Low cost Rainwater Harvesting system will provide an independent water supply other than drinking water.

STATEMEN '1' OF INVENTION Mains water is expensive and likely to get more expensive in the future. Every House Public! Commercial building; Small Business; Schools; Clubs. can reduce water consumption dramatically by implementing our rainwater harvesting system, instead of your mains water (drinking water) for a variety of uses.

The rainwater harvesting system will create a business — based on a single product, is simple to construct and can be sourced from the local building Low Cost Rainwater llarvcstiug System for Housing: Schools & Conm1crcia1J311i1<1iitgs materials providers while also supporting the local businesses.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be more clearly understood from the following detail drawing, with reference to the accompanying drawing: Figure 1a 8. 1b shows the House Rainwater Harvesting system detail drawing.

DETAILED DESCRIPTION "Low Cost Rainwater Harvesting System for Housing.

Schools & Commercial Buildings” The Low Cost Rainwater Harvesting System includes attic storage tank 150L (1). pump (11), hoppers (6) and 2 x 1000L water tank (14).

Referring to the drawings Figure 1.a illustrates detailed drawings of rainwater harvesting system within a two story standard dwelling house, Figure 1b. illustrate the house plan.

Hoppers (6) are placed a min 8ft or 2.4 m above the ground level. to collect 100% of the rainwater from each downpipe (8) connected to 50mm piping. all piping must be water tight and brought to (14) 2 x1000L water storage tank on ground level.

A pump (6) is placed in the storage tank (1) and water is pumped to the storage tank in the attic (1) and then supplied to the WC‘s (3) I washing machine (4) outside taps (20) lcar washing and watering garden.

A timer switch (24) is placed within the house for power to supply attic tank (1). also a float switch sensor (23) placed within the attic tank. An overflow (10) of 18mm is fitted in case of malfunction.

An on—off valve (19) is placed at WC's (3). washing machine (4). out side lap (20) in case of lack of rainwater. An overflow (10) is fitted at the 2x1000L extra 1000L storage tanks (14) can be added if required, storage tank (14) which in turn takes the access water to the storm water drain.
