About Us

WMEC are experts in designing and building effluent treatment systems for a wide variety of wastes.  We have clients in over 40 countries and in almost every industry type.

The Sentinel treatment system has been around for many years, treating agrochemical wastes using an optimised flocculation process.  Initially developed in conjunction with ICI in the 80’s as a method of treating washings from crop sprayers, the Sentinel became a worldwide success story.

WMEC was started over 20 years ago as a vehicle for the Sentinel technology.  As our client list grew we had more and more clients coming from non-agrochemical sectors and we found that the Sentinel system was applicable for many different waste streams.

Our continued commitment to research and development has led us to offer not only the Sentinel system of optimised flocculation but also pH Guard, bio and DAF.

WMEC head office is based in Chichester, UK where we manufacture all of our plants for the home and worldwide markets.

We believe that our staff are our best asset and as such have an excellent staff retention rate – some of our members have been with is for over 20 years.  WMEC is a great place to work.

WMEC is owned by two Directors with unparalleled experience in effluent treatment and the worldwide agrochemical market.  They are committed to offering our clients the best solutions possible for their effluent treatment.
