General System Principals

The JTP-2600HTc & 2600DPc rainwater harvesting (RWH) systems are designed to collect the water falling on the roof of a property and store it for subsequent re-use for non-potable purposes such as toilet-flushing, clothes washing machines and outside tap.

Although non-potable, the aesthetic appearance of the water supplied is maintained by passing the water through a high-quality filter before entry into the storage tank, storing the water in a stable cool temperature underground, ensuring the water cycles through the tank every 18-days or so, and passing it through a very fine-mesh in-line filter before it is supplied to the services. From the users' perspective, all operations of the system are entirely automatic with continuity of supply being achieved by an automatic mains-water top-up facility which caters for prolonged periods without rain.

All JTP systems are designed to integrate fully and cost-effectively with the overall water management arrangements for projects, including providing appropriate attenuation requirements as part of a combined SUDS/RWH system.

System Performance

The JTP-2600HTc & 2600DPc systems have been designed to conform to the requirements of BS-8515 (the national code of practice for RWH systems).

The systems are also designed to address national water-shortage issues, and to help developers meet the water-consumption requirements of BREEAM assessments, the Code for Sustainable Homes, and Building Regulations Part-G. The design therefore takes into account the size and occupancy of the building, together with anticipated local rainfall; examples of the RWH yield we calculate are shown in the table below:

Notes: 1. The numbers in italics show the anticipated yield of JTP-2600 systems in litres per year

2. For comparison purposes 2-people will use around 28,000-litres of non-potable water per year,

excluding garden irrigation
