Yorkshire Water and tech firm Technolog have pledged to reduce the in-home and environmental risk and impact of sewer flooding across Yorkshire following a successful pilot project, Utility Week reports.

The utility company – which supplies more than five million customers, the millions of people who visit Yorkshire each year, and some 140,000 businesses – will install 35,000 Technolog customer sewer alarms at properties across Yorkshire.

The move follows a successful pilot project involving 5,000 devices in Leeds, Bradford, Sheffield and Doncaster, which won the Institute of Water North Region Innovation award.

Once installed, the customer sewer alarms will monitor water levels within combined sewer gullies using a pressure sensor which sends an alert remotely when an increase in level is identified.

The devices use a wireless network allowing Yorkshire Water teams to identify trends in how sewers are performing, enabling the firm to quickly analyse, identify and proactively respond to increases in sewer levels which are often signs that precede sewage escaping the network onto streets or into people’s homes.
