Acton Storm Tanks is an existing Thames Water pumping station and storm water tanks site. The surrounding area is predominantly residential, industrial and mixed-use.

The site would be used to receive the main tunnel from Carnwath Road Riverside as well as intercept the existing Acton Storm Relief combined sewer overflow.

Works update


In mid-September we will start our bored piling works in storm tanks 5 & 6. The bored piling requires us to excavate a core within the ground and fill it with concrete to form the pile. They will create a structural foundation underground, enabling us to carry out the works required ahead of our main construction activities. The bored piling will take up to two weeks to complete.

Before piling can begin, the piling rig and the equipment that goes with it will need to be brought onto site. These deliveries are classed as abnormal loads. We will be closing Warple Way on Friday 21 September between The Vale and Canham Road for a short period, anticipated to be between 20.30 and 22.30, to be able to receive the deliveries. Read More

We are currently installing our sprayed concrete lining (SCL) batching plant. SCL will be used to line the drop shaft and requires a very high level of quality control. Prior to the drop shaft construction we are required to carry out some trials on the SCL material that will eventually form the drop shaft primary lining.

Trials will take place on Saturday 20 and Sunday 21 October and Saturday 27 and Sunday 28 October from 8am – 6pm and will be carried out at ground level within a controlled enclosure. Read More

Acton Storm Tanks - How we will minimise disruption

  • Hoarding will be erected along the site boundary
  • The fill material in the existing storm tanks will be compacted using low vibration machinery
  • Movements of vehicles onsite outside standard hours will be restricted
  • Advanced planting on the eastern and south-eastern boundary to form a tree line screen
  • Set limits to control activities, such as noise (Section 61 approval) from LB Ealing
