Waterguard SiteGuard

Designed specifically with CAR in mind, this system is a cost-effective way of eliminating the risk of water damage out of operational hours on any construction site.

The Waterguard SiteGuard will automatically shut off the sites temporary water supply when the site is closed, reinstating it when the site reopens.

This system is easily programmable to the sites individual working hours for every day with a daily timer for precise programming of working hours.
