We are licensed to provide these services and currently supply over 1,170 megalitres of water per day. This water is drawn from reservoirs, where it is collected and stored, rivers and groundwater sources. It is treated at our works before it is delivered by a network of pipes to homes and businesses.
In the north east of England, where we also provide sewerage services, waste water is then collected from these properties via the sewerage network and treated at our works before it is returned to the environment as either clean water or sludge which can be recycled as fertiliser or used to generate energy.
Our water and sewerage services in the north east cost an average householder 91 pence per day and in Essex and Suffolk area, 56 pence for a water only service.
The Water Services Regulation Authority (Ofwat), as the economic regulator, sets price limits for companies in England and Wales every five years. 2010/11 was the first year in the current five year investment plan. This regulation is performance based and companies are measured in terms of efficiencies related to operating costs, capital programmes and financing as well as their general operations. The regulated revenue of the company is set by reference to the rate of inflation, measured by the Retail Price Index (RPI), as well as an adjustment factor referred to as ‘k’. The profile of ‘k’ for the current five year period is shown below:
