This was a two-phase scheme, which began in August 2013 and was completed in October 2014.

  • Phase 1 works included the construction of over 450m of rider sewers and the construction of 20 manhole chambers to address localised incapacity within the combined sewer network serving a residential area within the Hebburn area
  • Phase 2 works were awarded under a separate contract. It began in March 2014 and took approximately eight months to complete. It involved constructing a 5,600m3 modular precast concrete gravity storm attenuation tank. This included internal half channels, benching and access manholes to alleviate surcharge within the main trunk sewer as well as two tunnels. The tunnels were built using a trenchless pipe jack technique at 8m deep, 1.5m diameter

The project also required significant landscaping and reinstatement work. This involved removing and re-aligning an existing bund which surrounded the playing fields, plus reinstating field drainage and playing fields over the tank area.
