Thames Water to build first new sewage works since 2005


 Planning permission was granted by Surrey County Council for a new Guildford Sewage Works.  The new works will be built on brownfield land and replace the existing site which Guildford Borough Council will use for local housing.


This will be the first new sewage works to be built by Thames Water since Reading STW opened more than 14 years ago.


Facilitated by Guildford Borough Council the new state of the art facility will cater for a growing population and eradicate odour while improving the local environment. 


Site of the new plant will have space for future expansion in line with modelled growth and the impact of climate change.

Work begins to transform two major junctions on A320 Woking Road Work to improve traffic flow, reduce congestion and enhance safety at the Woodlands Road and Moorfield Road junctions on Woking Road will begin on Wednesday 25 February 2026. These highways improvements are part of the wider Weyside Urban Village regeneration programme. Both junctions are being upgraded at the same time so the new traffic signals can operate together. This approach will help reduce exit blocking, ease congestion and improve journey reliability along this section of Woking Road. Woodlands Road junction improvements At the Woodlands Road junction on Woking Road, the existing roundabout will be replaced with a signal-controlled four-way junction. Co-ordinating this with the nearby Moorfield Road junction will help manage traffic more effectively and reduce delays, especially at busy times. Moorfield Road junction improvements At the Moorfield Road junction on Woking Road, a series of upgrades will increase capacity and improve traffic flow. A new northbound lane towards Woking will be added and the existing northbound lane will be converted to another southbound lane. Providing two southbound lanes approaching the junction will help to reduce congestion and make it easier for drivers to turn into the Slyfield Industrial Estate. A new signal-controlled pedestrian crossing will also be installed, alongside upgraded footways to improve safety and provide better connections with existing walking and cycling routes. Traffic management measures The scheme will be delivered in phases, starting with the removal of the Woodlands Road roundabout. This work will take place at night from Tuesday 2 March for around six weeks. A lane closure will be in place overnight for safety and lifted each morning to minimise disruption to daytime traffic. Councillor Vanessa King, Lead Councillor for Economy and Place said: “These improvements are another vital step in preparing the local road network for the Weyside Urban Village regeneration scheme. The new layouts will future‑proof the network for new homes and community facilities, while also helping to manage current traffic more effectively. Being committed to becoming a more environmentally responsible borough, we’re also placing strong emphasis on creating safer, more accessible routes for pedestrians and cyclists. “The Slyfield Industrial Estate is a major economic and commercial hub for Guildford, so improving access is essential for supporting local businesses. By delivering the works in carefully planned phases and managing traffic thoughtfully, we can keep the programme running safely while minimising disruption for residents, businesses and commuters.  “This project is ultimately about preparing the area for the exciting transformation ahead and ensuring that the right access is in place as new homes, infrastructure and facilities come forward.”
