Middlewich sewer improvements

We're carrying out improvements to the sewer network in Middlewich, building additional new equipment in the King Street area to store excess storm water. This will help to relieve pressure on the existing sewer system during heavy rain and improve the quality of water within the River Croco. Once conditions allow, the storm water would then be released back into the sewer network - so it can be treated and safely returned to the environment.

  • Across the North West we’re experiencing more frequent, heavy and prolonged rainfall which can overload the sewers. In Middlewich, if the sewer network reaches capacity, the storm water is released and diluted wastewater can overflow and enter into the River Croco.

    The work will improve the quality of the River Croco by capturing these storm spills and storing them temporarily, until they can be returned to the sewer system to be treated.

  • There’s an existing wastewater pumping station located off King Street, Middlewich. We're building a new covered storage tank to hold storm water, a control kiosk, underground connecting pipework and manholes. Once the work is complete the new equipment will be enclosed within a fenced and appropriately landscaped area next to the existing pumping station site. 

    We’ve carried out a range of environmental surveys and groundwork investigations to help develop our proposed solution. These plans also include tree and shrub landscaping around the new equipment on completion of the proposed work.

    We’ve purchased the area of land and will be using a proportion of this to build the new equipment. You can view further details about our work in the overview drawing, site layout planelevation drawings and visualisations.

  • Our customer information centre is now open and the team will be happy to answer any queries you may have about our work to help improve the quality of water in the River Croco. 

    Opening times will be displayed on the notice board at the front of the site.  Please plan your visit as the centre opens at different times each week.

    • Ground work to create the base for the new storm tank involved the installation of 68 concrete slabs - these were installed 15 metres below ground.
    • The tank was delivered in sections and assembled over a two week period.
    • Around 700,000 litres of water was used in the testing phase.
    • Work has now started to install the monitoring and control unit equipment.

    We've created a temporary compound to house site cabins, car parking and material storage area. Access into the site has also been adapted to allow easier access in from King Street, this is a permanent change and will help to reduce any traffic issues with tankers entering and exiting the access.

  • Temporary compound area: During the construction period we have created a temporary compound area to accommodate our team, materials and equipment. 

    Construction activity: This type of work will require the use of machinery which will create noise and vibrations. There will be additional traffic on the local road network as we receive deliveries. An integral part of our planning included the development of a traffic management plan to ensure disruption to the local community and road network is minimised as much as possible.

    Wash, flush…carry on as normal: Don’t worry, you will still be able to use all your existing appliances or facilities that take away the used water from your home or business just as you usually would while the work is carried out.

  • We're making improvements to the sewer network in Middlewich, but problems in the sewers can often be caused by flushing wet wipes down the loo or pouring fats, oils and grease down the sink.
