Improvements in your area

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 on our site at Mogden Lane.

We’ll then export this gas into the local gas distribution system. In order to do this, we’ll be building a new 1km biomethane export pipeline from our Waste Water Treatment site on Mogden Lane to the local natural gas distribution system on Chertsey Road.

When are you working?

Our work to install the export gas pipeline will take around a year to complete. We’ll start work in Summer 2022 and be finished in spring 2023.

Our usual working hours will be Monday to Friday 8am to 5pm. If required, weekend working hours will be Saturday 9am to 4pm and Sunday 9am to 1pm. Works will not take place during any period where there is a major rugby event at Twickenham Stadium. As a result of this it is highly likely that the majority of the works will take place in the summer and early autumn of 2022 in order to achieve our desired completion dates in the Spring of 2023.

How will this work affect me?

We’ll do everything we can to minimise any disruption to you while we carry out this work. The work may cause an increase to traffic as we’ll be working under lane closures you can find out traffic management plans in our information pack.

We're working with SGN on safety-critical water and gas main upgrades on Westhorne Avenue. By doing the work at the same time, we estimate that we'll save 14 days of work in the area.

What are we doing?

• We replacing old water pipes with new stronger ones to reduce leaks and bursts in the area.
• SGN will be replacing old metal gas mains to ensure a continued safe and reliable gas supply for many years to come.

When are we working?

• Joint work starts on Monday 14 February for around two weeks.
• Upon completion of the joint works with SGN, we'll continue to carry out further upgrades on Westhorne Avenue, until the end of September 2022.

Where are we working?

We will be working on Westhorne Avenue between the junctions of Birch Grove and Burnt Ash Hill.

Learn more about the project from our press release.

We’re upgrading Slough Sewage Treatment Works (STW) to increase capacity, enhance performance and improve the quality of water that’s returned to the environment.

This will involve upgrading the existing plant, building new treatment tanks, and putting in new treatment technology.

We’re also building a new below ground outfall pipeline to take some of the treated water and storm flows from the STW to the River Thames.

Environmental Impact Assessment work

We submitted an Environmental Impact Assessment Screening Opinion Request report to Slough Borough Council and Buckinghamshire Council in November 2021.

The report provided details on the assessment of potential environmental impacts in relation to the Sewage Treatment Works upgrade, pipeline and outfall works and concluded there will be no significant environmental effects associated with our work.

The report can be found on Slough Borough Council’s planning website.

In January 2022 we received confirmation from both councils that a full Environmental Impact Assessment for our works is not required.

We’re currently assessing the planning requirements for the scheme, and will provide further details on this in due course.

Why are you carrying out this work?

Wastewater entering the STW is forecast to increase by around 10% over the next 10 years. This means that we need to increase the capacity of the site now to meet the needs of the community in the future.

We also need to improve the quality of the water that’s returned to the environment and reduce flows in the network of ditches that take flows from Slough STW to the River Thames.

What are the benefits of this work?

As well as treating more wastewater as the area grows, these works will:

• Improve the quality of water that’s returned to the environment
• Reduce water industry-related flood risk along local watercourses
• Ensure that environmental flows are retained in the local watercourses
• Reduce odour around Slough STW
• Improve the resilience of Slough STW to reduce pollution risks

When are you working?

We’re developing designs at the moment and expect to start construction early in 2023. We expect the work to be completed and operational by early 2025.

How can I stay up to date?

In early 2022, when our designs are more developed, we'll be holding drop-in sessions for the local community. We’ll be sure to write to local residents and businesses closer to this time with details for these sessions.

You can find out more about the project along with our proposed pipeline route in this information pack.

Please check back here for further updates as the work progresses. If you live in the local area, we’ll be writing to you about upcoming drop-in sessions soon.

If you have any further questions in the meantime, please contact us on 0800 316 9800 and quote reference number BB975460.

Heath Lake is a 2.8 hectare lake within an area of woodland and heath, north west of Crowthorne.

It’s the only acid lake in Berkshire and has historically supported several rare aquatic plants. A designated Site of Special Scientific Interest, it’s owned and managed by Wokingham Borough Council.

The lake and its surrounding woodland provide the local community with superb access to nature, with a variety of walking routes through the lake and nature reserve.

What are you doing?

Housing development around the lake, as well as the five surface water sewer outfalls that now flow into it, have impacted the water quality of the lake. Over the years, silt carried into the lake by surface water and plant matter breaking down on the lakebed have caused a build-up of sediment.

We’re working with Wokingham Borough Council to remove this build-up. This will allow rare plants that have been lost to re-grow and improve the flora and fauna of the lake.

We’re also working to create a plan that will help us maintain the water quality of the lake in future. As part of this effort, we’re planning to install a small number of below-ground silt traps to catch sediment in our surface water sewers before it enters the lake.

We’re also looking at ways to create wildlife habitats and new viewpoints for the local community along the lake edge.

When will you be working?

We expect the work to start in Autumn 2022 and be completed by Spring 2023.

How will this affect me?

We’ll do everything we can to minimise disruption to the local community when we carry out this work.

As work progresses there may be a slight increase in traffic in the local area. We’re looking at ways to reduce the number of vehicles we use to avoid this as much as possible.

During our work on the lake, there may be temporary restrictions on public access around parts of the lake’s edge and in the nature reserve. This is to allow vehicles to access the area safely. We’ll keep temporary access restrictions around the lake to a minimum.

The nature of the work means that there may be times when noisy activity is taking place. We’ll keep the local community updated on our planned hours of activity and do everything we can to minimise disruption.

How can I stay up to date?

Please check back here for updates on our plans as they progress.

We’ll write to residents with details ahead of the work taking place nearer the time. In the meantime, you can find more information in our newsletter.

We held an online presentation for local stakeholders on 11 November 2021. 

If you have any questions about our work, you can email us.

For any other queries about Heath Lake, please contact Wokingham Borough Council. You can give them a call on 0118 934 2016 (select Option 2). You can also send them an email.

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 to our existing network by the O2 at Tunnel Avenue and at Millennium Way.

When will you be 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 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.

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

What are we doing?

Recently, our team have been installing reinforced concrete in the embankment. This will protect the reservoir structure and help prevent further cracks in the park paths. We’re just finishing the work on the drainage and creating new paths.

We’re also working with the council to reinstate the grass, and to redevelop the children’s play area with new equipment and surfacing. Take a look at this video to learn more about what we’re doing.

We aim to finish our construction work by end of May 2022. We’ll then be able to partially reopen the park with a full reopening in late autumn 2022.

Access to the park

We're sowing a wildflower meadow to improve the park for wildlife. To give it time to establish properly, the southern part of the park and the entrance at Poynings Road will remain closed. With good growing weather, we aim to keep this partial closure as short as possible.

The northern end of the park, accessed from Dartmouth Park Hill and Bickerton Road, will be opened to provide access to the newly renovated play area. In agreement with the council, we’ll put up a temporary fence to protect the grass embankment.

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 on our site at Mogden Lane. We’ll then export this gas into the local gas distribution system. In order to do this, we’ll be building a new 1km biomethane export pipeline (under lane closures) from our Waste Water Treatment site on Mogden Lane to the local natural gas distribution system on Chertsey Road.

Whitton Road and Rugby Road

This section of the works will be split into 3 phases:

a) Chudleigh Road junction - outside 159 Whitton Road will be carried out first with manual stop-go boards controlling traffic between the hours of 7am – 7pm Monday to Friday, and then using 3-way temporary traffic lights 7pm – 7am (overnight).

b) Outside 159 Whitton Road - junction with Rugby Road will be carried out by closing the left turning lane into Rugby Road with the existing traffic lights operating as usual.

c) We’ll then be working on Rugby Road under a north bound lane closure which will start on Tuesday 30 August 2022 and be finished by Friday 4 November 2022.

The works will be demobilised by Friday 4 November 2022.

Mogden Lane

Works will resume on Monday 9 January 2023 around the roundabout at the junction of Rugby Road and Chertsey Road for 3 weeks. We’ll be using temporary traffic lights to control the traffic.

The works will be demobilised by Sunday 29 January 2023.

Works will then resume in Mogden Lane on Tuesday 11 April 2023 for 4 weeks with the east bound lane of Mogden Lane closed from the roundabout to just before Beaumont Place.

Chudleigh Road

We’re planning to carry out this section of work over 3 weeks at the end of September 2022 to early October 2022.

A316 Chertsey Road

We’re working with Transport for London to agree dates to carry out the installation of the pipeline crossing of Chertsey Road.

When are you working?

Our work to install the export gas pipeline will take around a year to complete. We’ll start work Monday 15 August 2022 and be finished in spring 2023.

Our usual working hours will be Monday to Friday 8am to 5pm. If required, weekend working hours will be Saturday 9am to 4pm and Sunday 9am to 1pm.

Works will not take place during any period where there is a major rugby event at Twickenham Stadium. As a result of this it is highly likely that the majority of the works will take place in the summer and early autumn of 2022 in order to achieve our desired completion dates in the Spring of 2023.

We’ll do everything we can to minimise any disruption to you while we carry out this work. The work may cause an increase to traffic as we’ll be working under lane closures you can find out traffic management plans in our information pack.

Since 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 a letter informing them 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.

Why relining and not replacement?

We’ve been using these pipes for over 100 years, and they’ve served us well. But we need to carry out this essential work so we can safely transport our world-class water to your taps for the next 100 years.

Pipe replacement can be very disruptive to homes and communities, resulting in long road closures and noisy construction work. We use relining as an innovative alternative to minimise the impact of our work on you and keep water flowing for the future.

Where are you working?

We’re aiming to complete our work over the following two phases:

Phase 1

We started work in October 2020 and have had to extend our estimated completion date to the end of March 2022. During this time, we have successfully relined 500m of the 600m of the water main between 188 Seven Sisters Road and the northern end of Finsbury Park Road. However, in the final stage of the work, we encountered complications which mean that we cannot continue the relining in the same way.

To rehabilitate the remaining stretch of pipe between Blackstock Road and Finsbury Park Road, we will now install 20m of steel liner and reinforce the remaining pipework by relining the joints. This work will be completed by our team inside the pipe.

This new approach has now resulted in a further extension with an aim for our work in phase 1 to be completed at the end of March 2022.

We will continue to have sites in place at:

1 – 11 Finsbury Park Road  

Phase 2

We’re currently reviewing our plans for phase 2 of the project and we’ll write to customers for phase 2 closer to the time to ensure you are kept up to date.

Our work on phase 2 will not start until phase 1 is complete. However, you might see us in the area for short periods of time undertaking some initial survey work and repairs. We’ll write to customers for phase 2 closer to the time to ensure you are kept up to date.

What does this mean for me?

The work will be carried out in two phases. Phase 1 started in October 2020 and completion is now estimated for the end of March 2022. All work on Phase 1 will be completed before work on Phase 2 is started.

Currently in phase 1:

• The parking bays outside 1-11 Finsbury Park Road will be unavailable until the end of March 2022.
• We'll write to those immediately around our sites if we need temporarily suspend further spaces on Finsbury Park Road.

There may be some localised parking suspensions on Finsbury Park Road in the future if we need to get large equipment to and from our site. We’ll write to customers on the road closer to the time if these suspensions are needed.

Throughout our work, pedestrians and emergency vehicles will have full access to all roads. Bin collections will continue as normal.

Our onsite teams will update those immediately around our sites if any changes are required.

Will this work affect my business?

We’ll do all we can to reduce disruption while we work, but we understand your business may sometimes be affected. Learn more about what to do if this happens.

How can I find out more?

If you have questions about our work and wish to speak with someone, please call us on 0800 316 9800, selecting option one and quoting the reference number BB115405. Alternatively, you can also email us.

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.
