The Cartland Ripple Flood Alleviation scheme project was a £3million, year-long sewer upgrade scheme in the densely populated area of Stirchley in the South of Birmingham. It ran from January 2014 until March 2015.

We have been working with this client for over 20 years. Amey teams carry out clean water mains renewal and maintenance, as well as delivering sewer upgrades, flood alleviation projects and installing new or refurbishing existing pumping stations.

Regular flooding occurred at the junction of Cartland Road and Pershore Road. This led Severn Trent Water Asset Creation to assess the flooding in June 2009. They found the hydraulics to be complex at this location as the 1650mm Rea Main sewer joins the 900mm Griffins Brook sewer adjacent to the River Rea. In addition, terraced properties are densely packed with individual service connection to each property providing little room for excavation.

The purpose of the Cartland Ripple Flood Alleviation scheme was to alleviate 25 internal and 25 external sewer flooding problems in the area. This was to be achieved by the Amey teams:

  • Installing a kilometre of new, larger sewer pipes in the highway
  • Installing two, new large underground storage tanks
  • Introducing additional highway drainage and road gulleys

The high profile project required extensive stakeholder engagement and customer communication commitments. Before work began in January 2014, the Amey project team devised their own communication pledge to keep customers informed at all stages of the project. The success of this approach has led to it being shared as an example of best practice and learning tool amongst Amey’s network of ‘Customer Experience Leaders’.

Teams working on this year-long project have become so involved with the local community that many of them have used their ‘Amey community days’ to support local good causes.
