Mountfield sewer network improvements

We’re building a multi-million pound environmental scheme in Mountfield which will allow our customers to connect to a main sewer for the first time.

Most of the properties in the village are served by private facilities in the form of cesspools or septic tanks, which need to be maintained and emptied regularly to protect the environment.

Why we are doing this

Some years ago, Rother District Council found evidence of pollution in the watercourses and areas of land within the village and this was traced back to defective or poorly performing cesspools or septic tanks. It then applied to have us build a public sewer system to protect the village and improve its environment.

Our scheme

Our scheme will be delivered in two phases. We’re building a 1.9km sewer network, which will run through the village and under the railway crossing. We’re also building a pumping station. The second phase includes a wastewater treatment works in Solomons Lane. 

We’re delivering the improvements in two phases to ensure we have an effective solution and minimise disruption, while delivering best value for our customers. For our treatment works to operate effectively and efficiently - to guarantee a continuity of bacterial treatment – there is a minimum volume of wastewater which must flow through it. For this reason we will monitor the numbers of connections being made so we’re ready to go ahead with the second phase as flows approach the required level.    

In the meantime, we’re delivering the first phase, which includes all the sewer pipes, and, adjacent to Solomons Lane, a reception tank, the fencing, roads and landscaping of the treatment works site and car park. This means all the necessary infrastructure will be in place for the treatment works, when we come to build it.

The reception tank will be incorporated into the treatment works when we come to build it. For now, the tank will store the flows from the new sewers and we’ll use tankers to transport the waste to an existing works nearby where it will be fully treated.

Frequently Asked Questions

  1. Why have you been unable to complete the rail crossing? 
    • Having found an unmarked service when we started work on the agreed route for where the sewer would cross the railway line, we were unable to continue as originally planned.

      A revised planning application following a new route has been submitted to Network Rail for their approval.

      This route also requires new land access agreements to be to put into place, which we are currently working on.
  2. What about the homes to the south of the railway? 
    • Due to the delays to us constructing the sewer across the railway, we will be unable to accept any connections requests from the properties to the south of the railway until this has been completed.

      We will still progress the necessary infrastructure work to the south of the railway, so that these properties will have to option to connect once the sewer crossing point is in place. We will advise these residents once we are in a position for them to connect, if they wish to do so.

      There are also a number of homes (formerly owned by British Gypsum) on Eatenden Lane that are currently served by a private wastewater treatment works which is unconnected to our system. Having investigated the possibility of providing connection points for each of these properties, we have decided to continue with the original design agreed with Rother District Council.

      Instead, this means we will be providing one connection point for all these properties, allowing for possible connection to our network in the future. This connection point will be completed once land access is agreed.
  3. What is happening at the treatment works site? 
    • The first phase of work includes a building a reception tank for sewer flows, fencing, access roads and landscaping for the treatment works site and car park. The reception tank will then be incorporated into the treatment works, when we come to build it as part of phase two.

      For our treatment works to operate effectively and efficiently – guaranteeing a continuity of bacterial treatment – there is a minimum volume of wastewater which must flow through it. The reception tank will allow us to collect and remove sewer flows for treatment from those who have chosen to connect once the network is completed.

      Will we be monitoring the number of local connections and generated flows, so we are ready to go ahead with the construction of the treatment works when flows approach the required levels. Before any work can start on the site we need to make some alternations to the access.

      As this includes some work in the highway, we are currently working with East Sussex County Council to get the required agreements in place. We are hoping to be able to start work in mid-late August.
  4. Will there be any further road closures?  
    • Once we have approval to progress with the alternative rail crossing, we will need to put in a road closure on Eatenden Lane, as agreed with East Sussex County Council Highways team.

      We will also need to implement minimal traffic management on Solomans Land and Church Lane for a short period of time, while we construct the entrance for the treatment works and pumping station. The timings of these will be dictated by when the required approvals are in place.
  5. How will I know what’s going on? 
    • We are committed to ensuring that residents are kept up to date with progress of the scheme.

      Regular letters have been sent to residents and there are two liaison officers available to speak to residents who have any queries. This liaison will continue until the scheme is completed.
