Our Story

IWJS has a long history of successful change and innovation, adapting to shifts in markets and embracing new technologies. From its humble beginning, the Company has delivered services in many sectors. Most recently, IWJS has been best known for its superior service delivery, innovation, trusted partner approach and ability to invest. Over the years we have cleaned and surveyed thousands of miles of drains and pipelines across the entire UK and have become one of the leading companies within our industry. IWJS’s history dates back to June 1977 when Ken Cooper set up operations from Woolpit, Suffolk. One of his first jobs was cleaning safety kerbs on athletic tracks. It wasn’t long before IWJS were cleaning the council drains (later handed over to Anglian Water) in Essex, Suffolk and Norfolk. Eventually IWJS were doing the same for Yorkshire Water and Welsh Water with IWJS pioneering and dominating the tunnel cleaning industry in the 1970/80s.

2004 – Colchester office opened on Mersea Island, moved to Colchester depot in 2005 and again in 2011 to the current location at Marks Tey.

2010 – IWJS sold to Christopher Stewart. Christopher had been supporting IWJS for Adler & Allen through difficult times, so when the company went up for sale Christopher took the company on.

2011 – IWJS Group formed to manage the acquisition of Aquajet GB and DSSE which continued to operate as separate entities until 2014. This acquisition took the turnover to in excess of £25m.
