Description: Precise Pressure Control
Rapid urbanization across the globe has led to a marked increase in the demand for water, one of the world’s most valuable natural resources. Water stress, together with climate change, has significantly affected the availability of water to meet rising needs. On top of this, unaccounted for water losses — known as non-revenue water (NRW) — run into tens of billions of liters...

Water leakage falls into two basic categories. The first is background leakage from slow, long-term leaks. The second is burst leakage from sudden large-scale breaks.

The cost and environmental effect of leakage extend beyond the need to replace the water that never gets to the end user. Lost water can affect the environment by eroding soil, creating sinkholes, and damaging roads. Some of the water loss will leak into sewers or directly into a surface water recipient, which means the water is no longer potable. This is particularly serious in areas where the...

Description: Precise Pressure Control
The pressure in mains water supplies is provided by one or more pumps. The pump capacity is selected to achieve the maximum flow or head of pressure required by the utility. However, the average demand can be much lower than the peak. Because the rate of leakage can be directly related to pressure, controlling the pressure to match demand can have a very significant effect on water loss.

Drives can prevent the damage to piping systems that cause leaks and breaks in the first place. This damage results generally from water hammer and surge pressure.

Description: Precise Pressure Control
Water leakage is not just an economic issue, it is an increasingly important environmental issue. However, losses can be mitigated quickly and cost-effectively by regulating the pressure in water distribution networks to minimize the stress on aging infrastructure. Highly controllable variable speed drives offer a cost-effective solution that enables mains pressure to be adjusted to match demand....
