David Setford is a Chartered Civil Engineer and a member of the Chartered Institution of Water and Environmental Managers with over 40 years of experience in the wastewater treatment industry. In his first job as Senior Engineer at Southern Water, he spent the next few years designing wastewater treatment schemes before moving into an operations role, where he progressed to East Kent Area Manager, being responsible for the operation and maintenance of dozens of sewage treatment works and several hundred pumping stations.

He is the co-inventor of “Copaclear”, a foam tertiary clarifier licenced by Southern Water in 1988 for marketing by Pipeline Equipment – re-named Copa Products Ltd a few years later.

David joined Copa Products in 1990 as Engineering Manager, his prime role being to manage their growing engineering team, and to develop a process business, their product range in the early years being limited to simple screening systems. He designed the first Copa SAF prototype which was installed and trialled at South West Waters Ponsanooth STW in 1992. As Process Director, he designed his latest generation of SAF units using stainless steel tanks and pipework in the early 2000 s.

Whilst at Copa Ltd, David designed and built dozens of containerised wastewater treatment systems purchased by Halliburton KBR for use by the British Army at Camp Bastion, Iraq.

In 2006 Copa Ltd was acquired by a global company and absorbed into Eimco, then to become Ovivo. David (then Managing Director) left the business in 2007 and after a few years with Conder Ltd and Atac Ltd (where as a shareholder Director he designed their SAF units) set up Setfords Consultants Ltd in 2011, now incorporated as a trading division of Setfords Technology Ltd.

David is now a respected industry expert in SAF technology, and has assisted many Water Plc’s in the writing of their SAF specification and design standards.
