Type of works: Supply and installation of Cistermiser Washroom Control System.

One of the car-park toilets at the NEC was not connected to mains sewerage, but discharged into a large septic tank. The car park itself was only used during certain larger exhibitions, and the toilets were only opened when the car park was operational. However, NEC management identified a disproportionately high volume of metered water consumption through this toilet block, coupled with regular bills for emptying the septic tank.

Cistermiser quickly established that, in the Gents toilet, there were no urinal flush controls, and that the uncontrolled auto-flush urinal cisterns were continuously filling and flushing. As there were a substantial number of urinals and cisterns in this particular block, the obvious option of fitting urinal flush controls would involve a number of units and a significant initial cost.

Cistermiser offered its Washroom Control system, which triggers water services and electrical services on automatically when infra-red sensors detect movement within the washroom. It also swiches off during periods of non-use.

A Washroom Control system, tailored to control the services in the toilet block, was retro-fitted quite simply at a lower cost than providing individual urinal flush-controls. Strategically-placed PIR sensors ensured that water and electrical services remained on only when the toilet block was in service. The system also ensures that lighting is only switched on when ambient daylight is insufficient. The system not only brought the water-volume usage down substantially, but also provided urinal flush-control.

There was an immediate and sustained reduction in the frequency of septic tank emptying, and much reduced annual water bills. Electricity costs were also reduced, and the task of switching lights on and off in a remote building on such a large site was also eliminated.

The success of this installation resulted in NEC selecting Washroom Control for installation in a considerable number of other toilets within the NEC complex.
