Within this choice set, the preferred water tariff depends on multiple factors including: the goals of water pricing; the capacity of a water services supplier to allocate its costs, to price water, and to collect revenues from its customers; the price responsiveness of water consumers; and what is considered to be a fair or just water tariff.

In March 2003 Thames Water identified that by 2005 there would be a deficit in water treatment and supply capacity in North London. To address this deficit a new water treatment facility was constructed on 1.5 ha site adjacent to the William Girling reservoir and the A110 road ( 51°38′11″N 0°00′57″W / 51.63629°N 0.01582°W ...

A major part of London's water supply infrastructure, the initial ring was constructed by Thames Water between 1988 and 1993 at a cost of £248 million (equivalent to £638 million in 2023), and when completed, it was the longest tunnel in the UK.
In the United States, the typical single family home uses about 520 L (138 US gal) of water per day (2016 estimate) or 222 L (58.6 US gal) per capita per day. This includes several common residential end use purposes (in decreasing order) like toilet use, showers , tap (faucet) use, washing machine use, leaks , other (unidentified), baths , and ...
Water is abstracted from the River Thames downstream of Penton Hook Weir at up to 200,000,000 imp gal (910,000,000 L; 240,000,000 US gal) [8] and flows via the 1.26 km Laleham Aqueduct to a pumping station (51°24'56.0"N 0°28'36.9"W) at the western embankment of the reservoir. The pumping station lifts water into the reservoir.
