Thames Water

Thames Water

Thames Water is the UK’s largest water and wastewater service company. It supplies 9 million water and 14 million wastewater customers across London and the Thames Valley. It manages 32,000 km of water mains, 108,000 km of sewers, 100 water treatment works and 350 sewage treatment works.

Thames Water is Probit’s first client and is using AIM for water main and sewer assets to quantify the investment required to achieve levels of service for customers. This feeds into their next five-year planning cycle, in which proposals are submitted to their regulator, Ofwat, to determine the investment companies can make and future bill limits for customers. Asset Investment Manager has also been used for water resource management planning to identify how Thames Water will maintain water supplies over a 25 year period.
