Efficiency and Control
Active pressure control is the most effective strategy to reduce leaks in drinking water distribution networks. By precisely regulating pressure in each hydraulic sector, passive leak losses are minimized, network service life is extended, and energy consumption is reduced.
Marfel has implemented pressure control projects in networks with up to 9,784 water connections, achieving proven flow recoveries of 18.54% — equivalent to 12.78 LPS of water recovered in a single district metering area.
Real case: flow reduction from 81 to 68 LPS — 18.54% recovery
Active pressure control implemented by Marfel in a real network with 9,784 connections demonstrated the following results:
| Parameter | Before Control | After Control |
|---|---|---|
| Maximum Pressure | 4.75 kg/cm² | 2.85 kg/cm² |
| Minimum Pressure | 2.75 kg/cm² | 1.93 kg/cm² |
| Average Flow | 81.073 LPS | 68.39 LPS |
| Flow Recovered | 12.78 LPS — equivalent to 18.54% |
These results show that investment in active pressure control is typically recovered in less than 2 years, while the benefits in leak reduction and network service life extend for decades.
