Water Metering

Professor Carmine Ornaghi and Professor Mirco Tonin

Water is a scarce resource. Managing water demand is increasingly important in countries confronted with constraints on water supply due to extended periods of drought, leaks in an ageing supply infrastructure and concerns about the environmental impact of water extraction.

Although the necessity to promote an efficient use of water receives widespread consensus among users, there is no similar consensus on how water metering and tariffs should be designed to reach this goal. In particular, the prospect of paying for water is often seen as a regressive tax at a time when the incidence of energy and water poverty is increasing among households with a low income.

Installing a meter is a necessary pre-requisite for introducing some form of price mechanism to manage water consumption.
