» BREEAM Water Leak Detection System [Type WG]

The Aqualeak BREEAM WG 'in-pipe' Water Leak Detection System was specifically designed to meet and exceed the Building Research Establishment's BREEAM Credit Criteria assessment applications, W02 and W03, and will qualify for the granting of the "Credit Point". These criteria are specified for energy efficient buildings where water leak detection is required between the property boundary and the building, and internally within the building. The system is designed to monitor water flowing through the incoming water pipe and if the amount goes beyond the adjustable pre-set limit this product will raise an alarm and [optionally] shut off the water supply. Similarly, our AquaPIR Systems will shut off the water supply in the washrooms to conform to BREEAM criteria W04.

The system comprises of a two-zone WG2 Control Unit which would be linked to two turbine sensors. The first turbine would be fitted just after the utilities water meter and would monitor the water pipe external to the building. The second turbine would be fitted just after the stop-cock inside, and would monitor for leaks within the building. The turbines provide a 'pulse' as water flows through them. Should the adjustable pre-set quantity of pulses/litres be exceeded, the WG system would provide local audio-visual alarms, and the output relay/s would provide a signal to remote alarms or BMS. If required, the system can also shut off the water supply via the optional solenoid valve/s.

The system is fully programmable to detect different leakage rates over set time periods. As the building may be occupied during the day and as the water usage may be constant, the Controller is also provided with an integral timer that can be set so that the System would operate only in 'out-of-hours' periods. The system can then either turn off the water completely at say 6pm, or can be set to alarm/shut off water on the basis of a quantity of water flowing through the Meter. WG Systems are available to suit a wide range of industrial pipe sizes: 15, 22, 25, 30, 40, 50, 65, 80, 100, 150 and 200mm (imperial 1/2" to 8"). 

Single zone WG1 System (shown left) would be used in non-BREEAM applications requiring monitoring of a domestic incoming water supply into the building, for local monitoring of specific area/s and for providing individual shut-off facilities. Smaller domestic systems suitable for 15, 22 and 28mm are also available, with flow sensors rather than turbines, and with simpler more economical control systems. Domestic systems are widely used to monitor flats and houses and to shut off the water if a leak occurs.
