Utility water applications and instruments used

Water utilities in the UK and Ireland face strict compliance requirements under WRAS, DWI, and Uisce Éireann standards. Operators must maintain water quality, optimise chemical dosing, and monitor flow and pressure without disrupting supply.

This page explores 12 key applications and the technologies that support them, helping utilities achieve efficiency, reliability, and regulatory compliance.

Typical applications

Chemical dosing and metering

Chemical dosing is essential for disinfection, coagulation, and corrosion control in water treatment. Accurate dosing prevents under-treatment, which risks contamination, and over-treatment, which wastes chemicals and breaches discharge limits. UK and Irish utilities rely on precision dosing to meet environmental and drinking water standards. Automated systems reduce manual intervention, improve repeatability, and integrate with plant SCADA for real-time control.

Relevant products:

Longer Peristaltic Pumps (G100, G300, T-S403, KZ10) - These pumps deliver precise volumetric dosing for chemicals like sodium hypochlorite and bisulfite. Their compact design suits skid integration, while RS485 and 4–20 mA control options enable automated dosing.
Key benefits:
- Easy integration with PLC systems
- Compact footprint for confined spaces
- Handles viscosities up to 200 cSt
- High accuracy for low-flow dosing
Fluid metering Dispensing Pumps - Ideal for ultra-precise metering in pilot plants or critical dosing points. Ceramic internals ensure chemical compatibility and long service life.

Key benefits:

Exceptional repeatability
Corrosion-resistant wetted parts
Suitable for aggressive chemicals
Low maintenance design

pH adjustment and neutralisation

Maintaining pH within safe limits is vital for water quality and corrosion prevention. Automated dosing systems ensure consistent pH correction, reducing operational risk and meeting compliance targets. pH control is critical in both potable water treatment and wastewater discharge processes.
