Thames Water is the private utility company responsible for the public water supply and waste water treatment in large parts of Greater London, the Thames Valley, Surrey, Gloucestershire, Wiltshire, Kent, and some other areas of the United Kingdom. Thames Water is the UK’s largest water and wastewater services company, and supplies 2.6 gigalitres of drinking water per day, and treats 4.4 gigalitres of wastewater per day.
Their 15 million customers comprise 27% of the UK population.
Thames Water estimates that by 2045 there will be a water shortfall of 360 million litres per day in London alone. One of the biggest problems faced by Thames Water is leakage, with 98% of this occurring underground and therefore harder to detect.
Thames Water needed a way to effectively manage its water consumption across their sites in a streamlined and efficient way.
We have been able to help Thames Water tackle these issues in a number of ways. We have been able to supply Thames Water with Walk by/Drive by systems for the meter readings, and in more recent years have supported the trials and implementation of loT Low Powered Wide Area Networks (LPWAN).
We monitor 132 Thames Water sites across London via a LPWAN fixed network and provided hourly consumption data on all meters. These sites include primary schools, retail establishments, government buildings, leisure facilities and prisons with a particular focus on areas with stretched water resources.
By using our technology, Thames Water is provided with live consumption data which has helped them better understand their usage and efficiencies. Our technology ensures Thames Water customers have the correct meter size and real-time consumption data. We are able to highlight and alert wastage and leakage issues within days of installation.
38.5% of meters monitored were showing a high probability of leakage or unknown water useage of 40+ litres per day. Our data was able to alert Thames Water to this an has enabled them to focus on fixing leakage issues effectively.
Our longstanding relationship with Thames Water has not only helped them to save money but has also aided them in becoming more sustainable in their effort to tackle water shortage.
