4Delivery are building a new sewer and pumping stations to move wastewater from Peacehaven, Telscombe, Saltdean, Rottingdean, Woodingdean, Brighton and Hove to the site of a new Wastewater Treatment works at Lower Hoddern Farm, Peacehaven, which is also being built.

A new sewer tunnel

An 11km sewer is being installed by tunnelling at a depth of between eight and 40 metres below ground level. Before tunnelling starts precondition surveys will be carried out on all properties that are directly above the route of the sewer. Shafts are being built along the route to enable local sewer connections to be made.

New pumping stations

4D are also building two underground pumping stations to help move wastewater to the new treatment works.

One pumping station will be on existing Southern Water land at Portobello Treatment works and will be covered with a grassed roof, and has been designed so that it does not affect sea views. The other pumping station will be in a traffic island in the middle of Marine Drive and surrounded by a domed structure which has been designed to integrate with the landscape and minimise the effect on sea views.

Health and safety is our priority

The safety of the public and the workforce is the highest priority. For every safe day worked on site 4D donate money to local charities. For more information about our health and safety record, please take a look at our health and safety page here.
