Improvements in your area

We're currently carrying out the following long-term improvements.

New water main in Greenwich

We’re laying a new water main to transport water across East London, running from Deptford to the Greenwich Peninsula. Around 4km in length, this new water main will serve both existing and new customers in the area.

Where will you be working?

The path of the water main will take it across Greenwich Park, and then along:

• Park Row
• Trafalgar Road
• Old Woolwich Road
• Lassell Street
• Banning Street
• Pelton Road
• Christchurch Way
• Telcon Road
• Tunnel Avenue
• Millennium Way
• Blackwall Lane

The water main will then connect into our existing network by the O2 at Tunnel Avenue and at Millennium Way.

When are you working?

The first part of the water main will be laid across Greenwich Park, from Croom's Hill to Park Row access gate. This first phase is scheduled to take place between 6 September 2021 – 28 February 2022.

The whole water main will take approximately 30 months to complete.

How will this work affect me?

We’ll do everything we can to minimise any disruption to you while we complete this work. Temporary road closures may become necessary to ensure we can operate safely. We’ll keep you informed as work progresses - please continue to check back here for further updates.

Our work in Dartmouth Park

We’re carrying out upgrade and improvement work to Dartmouth Park Reservoir. This will also fix the problem with paths cracking in the park.

When we’re working

We’ll start at the end of June 2021 for about nine months. We’ll be working Monday to Friday from 8am to 6pm.

How you’re affected

Throughout our work the east side of Dartmouth Park will be closed, between the Dartmouth Park Hill entrance, the children’s play area and the park entrance on Poynings Road. The area of park off Bickerton Road will remain open. The basketball and games court will only be accessible from Bickerton Road.

The children’s play area will be removed. We’re working with Islington Council to provide a new play area once our work is complete. This will include replacing some play equipment.

We’ll do our best to limit disruption from noise and vehicle movements. Your water supply won’t be affected by this work.

Biomethane installation at Deephams Sewage Treatment Works

This project will allow us to use the leftover gas from our sewage treatment process to heat local homes with renewable energy. It will also be a big help in our plans to become a carbon negative business by 2040 with the first milestone: net zero 2030.

Where will you be working?

The installation will involve some minor work in a small area in the southeast corner of the site, near one of our site gates on Ardra Way.

When are you working?

Our work to install and test the unit will take around 8 months to complete. We’ll start work in August 2021 and be finished in spring 2022.

Our usual working times will be between 7.30 am and 4.30 pm on weekdays. We’re not intending to work any weekends during installation. However, there may need to be some weekend working between January and March 2022, when we test the new equipment.

How will this work affect me?

We’ll do everything we can to minimise any disruption to you while we carry out this work. Although we are working close to the southern boundary of the site we don't expect our work to affect any of our neighbours.

The work may cause a slight increase to traffic in and around the site and along Adra Way. However, construction traffic for this project will be unlikely to pass through the main site entrance on Pickett’s Lock Lane.

Protecting water supplies from Seven Sisters Road to Myddleton Avenue

Since 19 October 2020, we’ve been working hard to rehabilitate 600m of our 36-inch water mains between Seven Sisters Road and Finsbury Park Road in Hackney, London. We’re using a technique called ‘relining’ which involves pulling 600m of new pipework through the current pipe to reline it.

We recently sent customers living in affected areas letter informing of a delay to our work and outlining the improvements we're making, along with how we'll be working to minimise disruption.

Please always check here for the most up-to-date information.

Upgrading Beckton Sewage Treatment Works

We’re upgrading the site to ensure it can treat the sewage of up to 4.4 million customers and accommodate flows from the Thames Tideway Tunnel, which is due for completion in 2024.

We expect the work to start in March 2021 and to be completed by the end of March 2023.

How will the work affect me?

We'll carry out our works on site between 7am and 7pm Monday to Friday and 7am and 1pm on Saturdays. We may occasionally need to work outside these hours to complete a specific activity, but this will be kept to a minimum and we don't anticipate this affecting local residents.

There may be some increased site traffic into the site and along Eric Clarke Lane. We'll manage this via the A14 and Jenkins Lane.

How can I learn more? 

Look at our information pack for more details. We’ll write to keep businesses and residents in the area updated with any changes to our work.
