ATWM—Installation & Maintenance
A.
GENERAL INFORMATION
The AT-WM is a pulse water meter, leak monitoring system that has been specifically designed to help achieve the
requirements of BREEAM 2011 (BRE Environmental Assessment Method).The AT-WM system will allow designers,
M&E contractors and developers to achieve the “Credit” available to reduce the impact of water leaks that may
otherwise go undetected. The system is designed to monitor water flowing through a pulse water meter. If the
volume of water reaches the pre-set limit (customer adjustable) the system can isolate the mains water pipe,
therefore limiting the amount of water and leak damage.
