WAT02 BREEAM Compliance
The specification of a water meter on the mains water supply to each building; this includes instances where water is supplied via a borehole or other private source. Water-consuming plant or building areas, consuming 10% or more of the building’s total water demand, are either fitted with sub meters or have water monitoring equipment integral to the plant or area. Each meter (main and sub) has a pulsed output to enable connection to a Building Management System (BMS) for the monitoring of water consumption. If the site on which the building is located has an existing BMS, managed by the same occupier/owner (as the new building), the pulsed water meter(s) for the new building must be connected to the existing BMS.
WAT03 BREEAM Compliance
A leak detection system which is capable of detecting a major water leak on the mains water supply within the building and between the building and the utilities water meter. The leak detection system is: Audible when activated Activated when the flow of water passing through the water meter/data logger is at a flow rate above a pre-set maximum for a pre-set period of time Able to identify different flow and therefore leakage rates, e.g. continuous, high and/or low level, over set time periods Programmable to suit the owner/occupiers’ water consumption criteria Where applicable, designed to avoid false alarms caused by normal operation of large water-consuming plant such as chillers. For an additional credit One of the following types of flow control device is fitted to each WC area/facility to ensure water is supplied only when needed (and therefore prevent minor water leaks): A time controller i.e. an automatic time switch device to switch off the water supply after a predetermined interval A programmed time controller i.e. an automatic time switch device to switch water on and/or off at predetermined times. A volume controller i.e. an automatic control device to turn off the water supply once the maximum preset volume is reached. A presence detector and controller i.e. an automatic device detecting occupancy or movement in an area to switch water on and turn it off when the presence is removed. A central control unit i.e. a dedicated computer-based control unit for an overall managed water control system, utilising some or all of the types of control elements listed above.
Utilities Meter
A water meter provided and installed by a water utilities company in order for them to measure water usage and calculate water bills. This meter cannot be used in conjunction with any water leak detection system due to issues with ownership and accuracy.
