Sewer and wastewater monitoring

Sewer and wastewater network monitoring and management.

Through our group company Detectronic, we help water utilities prevent flooding, reduce pollution, and improve rivers and bathing water through an analytical, innovative, and creative approach to problem solving.

We facilitate real time management of sewerage systems by monitoring wastewater flows and effluent levels at CSO's and other critical points in the network. Combining their online portals with their flow and level monitors create a highly effective sewer network monitoring system.

We provide flood management risk solutions focusing on measuring, recording, reporting, and reacting to wastewater depths and flow rates.


Flow surveys

Our flow surveys determine what is happening in the sewer network using a combination of water flow, velocity, and depth readings. They are often used to detect inflow and infiltration rates, bottlenecks in the sewer system and sewer capacity.

Flow and load surveys

A water flow and load survey can reduce your water bills, help manage compliance, DAF plans and process efficiencies.

Trade effluent services

We offer a range of trade effluent monitoring systems and services to help keep you compliant and can save you money.

CSO monitoring

We work with water utilities to implement comprehensive CSO monitoring and comply with Combined Sewer Overflow regulations through smart sewer network monitoring programs.

Wastewater management

We provide real-time detection and alarm notification, enabling smarter wastewater management and preventing environmental damages, costly clean ups, fines, regulatory penalties and negative publicity.

Flow meter hire

All our flow meters are available to hire on a weekly or on-going basis with all equipment configured to your needs and application.

On-site services

We provide installation, maintenance, calibration and commissioning services for flow and level monitors throughout the UK.

MCERTS monitoring
