A joint venture between Veolia, Costain and MWH

Who We Are

The 4Delivery Joint Venture (JV) has enabled the strengths of three industry-leading partners to combine their expertise in delivering capital investment projects for Southern Water Services over three consecutive Asset Management Plan (AMP) periods since 2005.

Veolia, Costain and MWH formed the 4Delivery (4D) JV at the commencement of AMP4, providing engineering, procurement and construction services in the delivery of over £1.3bn of projects across Kent, Sussex, Hampshire and the Isle of Wight. 

During this time, 4D built an enviable reputation in setting consistently high standards in the safe, timely, reliable and cost-effective delivery of a capital programme, operating both proactively and reactively to the needs of the client through the adoption of four simple yet essential values – respect, agility, innovation and collaboration.

As a result, 4D has become one of the most successful delivery vehicles since the UK water sector was privatised over 25 years ago.
