Improving the efficiency and reliability of water systems

Distributing water on a large scale is a particular challenge in high-rise buildings, and with a trend for designers to build up in urban areas, rather than out, it is an issue that has become a new focus for design engineers.

The need to improve the mechanics of building water distribution systems is driven by two fundamental needs: firstly, the need to increase efficiency, and in doing so, decrease
water wastage; and secondly, to improve the reliability of the installed systems, thereby reducing the ongoing cost of maintenance and repair.

Old-world thinking

Old technology pumps in large industrial
water systems typically use pressure switches calibrated to switch the pump on if the water pressure falls to below a specific point (say, below 50psi) and off if
the pressure exceeds a given parameter (for example, 70psi). This operation is fine up to a point, but it essentially means that the pump is either working at full
speed or not at all, and these surges in demand placed upon a mechanical system may lead to problems with reliability and repair.
