Slyfield Sewage Works on the Move

Planning Permission is being sought.

Thames Water plan to relocate the Guildford Sewage Treatment Works (STW) as a like-for-like replacement of the facilities, which treats wastewater for around 120,000 people.  Thames Water expect to submit a planning application to Surrey County Council, as the waste planning authority, in late 2021

The relocated works will take into account new housing developments within the catchment for the STW; and also provide further room for expansion.  The new STW will meet the latest Environment Agency standards particularly for discharged water quality.

The relocated works are planned to occupy approximately 8 hectares to the north east of the Slyfield Industrial estate; with vehicle access from North Moors and Westfield Road.

The STW is being built on the former Slyfield landfill site.  The design will avoid having to remove large quantities of landfill, most structures will above ground level on piled foundations. The STW will be raised slightly compared with current site.

Claimed Benefits

• The move will enable Guildford Borough Council to build 1,500 new homes. as part of the new Weyside Urban Village.
• The new STW will make use of a former landfill site at the northern edge of the Slyfield Industrial Estate, which can’t be used for housing development.
• The new STW will future-proof wastewater treatment capacity to handle the growing population in Guildford.
