GRP Pump Enclosure with built in Tank

GRP Pump Enclosure with built in Tank
The unit is designed as a single piece item with an internal dividing wall at full height.
One internal section being the wet compartment for the stored water which is accessed via a lid mounted lockable manway.; Beyond the internal dividing wall is the dry side where the booster set is to be positioned. The internal dividing wall has the inlet and outlet connection within it, the overflow, warning pipe and screened spill over weir terminate through the wet side wall to outside and do not therefore normally require any additional pipework.
The dry side is accessed by a large 1600 x 1600mm hinged and lockable door, which is fitted with louvered vents to ensure adequate ventilation. If chosen with the Foundation Skid the whole unit is mounted & fixed too a fully welded galvanised steel skid which allows offloading and movement on site by fork lift struck. The principle is to provide the unit to the booster set manufacturer where the booster and associated electrical equipment can be fitted.
The completed unit can then be delivered to site where once positioned it requires the simple connection of the mains pipework, outlet pipework to the services, and electrical supply, making it a “plug and play” unit requiring minimal onsite installation.

Water Leak Detection Systems

Water leak detection is widely used for a host of different applications and in many different environments. The principle behind this technique for water leak detection is based on the conductivity that exists in water. Using a sensor tape, probe or pad it’s possible to cover large areas that are sensitive to water leaks. Each sensor type has two conductors kept apart by an insulator. As soon as water bridges the gap between the conductors an alarm is triggered.

Water leak detection is the method used to determine a problem with a plumbing system resulting in an escape of water. Water leak detection has become a standard in many industries protecting data centres, comms rooms, plant rooms, WC areas and kitchens.

More recent developments in water leak detection come by way of new systems of communication. It is now possible to connect a text message dialler to a water leak detection alarm panel and have it send a message as soon as leak occurs.


BREEAM Water Leak Detection Systems

BREEAM Water Leak Detection Systems

The LeakSaver has been specifically designed to help achieve the requirements for BREEAM WAT02 (consumption) and WAT03 (major leak detection). By installing a water meter at the boundary to the property and another where the mains cold water enters the building, both external and internal water leaks can be detected by the alarm panel. The system has been designed to allow the readings from the external water meter to be split, one part can be connected to the BMS for monitoring consumption (WAT02) and the other used by the LeakSaver to monitor for water leaks;

Tanks Direct - Water Storage Tanks

  • Our water tanks are made from food grade medium density Polyethylene.
  • Our water tanks are UV resistant and extremely tough.
  • Our water tanks can also be used to hold diesel or heating oil.
  • Our plastic water tanks are translucent making the water level visible through the tank.

OUR BAFFLED WATER TANKS ARE IDEAL FOR WINDOW CLEANERS, since the latest regulations came in window cleaners need to hold a large quantity of water in their vehicles. Car valeters are also using these plastic water tanks to hold all the water they need to supply their pressure washers in their vans.
