Hitchin Mains Improvement

Starting 1st February 2016 for 6 months


Why are we installing new mains in this area?

The water supply to Hitchin flows through a single trunk main. We are going to be installing new pipework between Waitrose in Bedford Road and Windmill Hill Reservoir, to provide a back up to the existing 9 inch diameter pipe. We will also install a new valve and connection pipework on the 18 inch diameter pipe in Wymondley Road, to give us more control on the trunk main.

If we don’t carry out these works, there is a risk that over 5,000 properties could be left without water if there was a burst on this pipe.

We are investing £0.9 million to improve the resilience of the water network in Hitchin. These works are absolutely essential to make sure we continue to provide a reliable supply of water to the community in the future. The work will also improve the water pressure in the western part of Hitchin.

What are we doing to minimise the traffic disruption?

We know this is going to cause disruption to people in Hitchin and the surrounding areas affected. We would like to apologise for the inconvenience caused but the work is essential.

We have been working closely with Hertfordshire County Council, the local Highways Authority to plan this work so we can reduce disruption, as much as possible.

We would like to assure you that the traffic management measures we have put in place are needed to ensure the safety of motorists and our technicians
