Improving the efficiency and reliability of water systems
07 October 2019
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 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.
