General System Principals

The JTP Rain Harvesting garden rainwater harvesting (RWH) system is designed to

collect the water falling on the roof of a property and store it for subsequent re-use for

garden-irrigation or other outside-tap applications. The water supplied is suitable for

these intended, purposes, but ingestion is to be avoided.

The system is supplied on the understanding that the user intends to harvest rainwater

during the generally wetter months between September to May, to provide water for

irrigation purposes during the drier/warmer summer months. If it is intended to use the

system to a different pattern of usage, then we would be pleased to advise accordingly.

As the intention is to have the maximum amount of water available for irrigation during

the summer, it is the user's choice which size of storage tank is selected; this is unlike

full domestic systems where tanks must be sized in accordance with BS-8515.

Similarly, as water is being collected throughout the winter ready for summer use, there

would generally be no need to harvest rainwater from the whole roof; this, together with

the fact that the plumbing arrangements inside the property are not affected, greatly

simplifies installation arrangements and makes retrofitting a cost-effective option.

The water supplied by the system is not subject to hose-pipe bans or water restrictions,

as it is not supplied by the water utility company.

System Performance

The Table below shows the theoretical amount of rainwater that can be harvested each

year; the amount actually harvested will depend upon the size of tank selected, and the

pattern of usage:

700
800
900

50-sq m
22,500

Notes: 1. The numbers in italics show the quantity of water available for collection in litres per year

2. As a broad guide to consumption, a garden sprinkler on full-flow delivers around 500-litres per hour
