The UK’s water meters, used by households, businesses and businesses for irrigation and for monitoring the quality of water, are due to be replaced in the next five years.
The Met Office has said the replacement will be complete by 2020.
This follows a review of the water supply system by the Office for National Statistics, which found that the supply of water for drinking, heating and domestic use had been “substantially reduced”.
The Met said the changes would bring in more efficient water delivery and better efficiency of water use by water companies.
Water shortages have been widespread and have prompted calls for the UK to be forced to build a water network in order to meet the water demand of the population.
Water for domestic use and businesses will continue to be provided by the National Grid, which supplies water to the country, but the Met Office said it would also provide water to those with water usage of 1.2 million litres per person per day.
There is currently no plan for the replacement of existing meters, but water users can contact the Met to request their replacement.
It is expected that a total of about 2.5 million meters will be replaced, according to the Met.
The government said that the changes are being made to ensure that “the water supply and supply systems for people and businesses are up to date”.
The Government said that it would be working with the private sector to ensure the water metering system is “efficient, effective and cost effective”.
The replacement of the meters will mean that there will be a new system of water meters that will be in place across the UK, but this will take at least four years to implement.
The new meters will require no further funding.
It comes after the Met office reported that a third of all households in the UK had been left without water.
The number of households without water rose to about 2 million in 2015, according the Met, with some areas reporting an increase of more than 10%.
A new report from the UK Water Information Agency found that about half of all water users had not yet been able to get water.
It said that some areas, particularly those in rural areas, were having to rely on the local water utility.
Water usage of households and businesses has risen in recent years, according and estimates from the Met and the Department of Energy and Climate Change.
The increase in water usage, which has increased by 30% over the past four years, is primarily because of the introduction of fracking, a process that involves injecting water deep into the ground to fracture rock.
It has led to more leaks and increased pressure in the ground, causing groundwater to become salty and therefore less able to hold water.
But the use of fracking has also led to a rise in the amount of waste water pumped from the earth into the sea.
