The government has announced a three-year project to accelerate the rollout of broadband and mobile signal in rural areas by feeding fibre-optic broadband cables through the United Kingdom's water pipes.(1) The government says that the scheme could also help to reduce leakage from the public water supply.
To trial what could be a quicker and more cost-effective way of connecting fibre-optic cables to homes, businesses and mobile masts, without the disruption caused by digging up roads and land, £4 million is being made available to innovators.
Digital Infrastructure Minister Matt Warman said as follows:
The cost of digging up roads and land is the biggest obstacle telecoms companies face when connecting hard-to-reach areas to better broadband, but beneath our feet there is a vast network of pipes reaching virtually every building in the country. So we are calling on Britain's brilliant innovators to help us use this infrastructure to serve a dual purpose of serving up not just fresh and clean water but also lightning-fast digital connectivity.
The project will also look to test solutions that reduce the amount of water lost every day due to leaks, which is 20% of the total put into the public supply. It will involve putting connected sensors in the pipes, which will enable water companies to improve the speed and accuracy with which they can identify a leak and repair it. Water companies have committed to delivering a 50% reduction in leakage; this project can help to reach that goal.
The government says that deployment challenges for essential utilities such as water and telecoms are complex and tightly regulated because both are parts of the United Kingdom's critical national infrastructure. The project will consider these regulatory barriers as well as the economic, technical, cultural and collaborative challenges and the impact on consumer bills. Fibre has already been deployed in water pipes in other countries such as Spain.
Any solution used to trial fibre-optic cables in the water mains will have to be approved by the Drinking Water Inspectorate (DWI) before being used. The government has explained that the DWI requires rigorous testing ahead of approving any products that can be used in drinking water pipes.
The government is already considering giving broadband firms access to more than 1 million kilometres of underground utility ducts – including electricity, gas and sewer networks – to boost the rollout of next-generation broadband. The government will soon respond to a consultation on changing regulations to make infrastructure sharing easier.
The Fibre in Water project is due to conclude in March 2024. The final year of the project will explore scaling proven solutions across the country. The deadline for applications to the competition is 4 October 2021.
