The continued growth in this market, led to the formation in 1965 of Marshall Pump Systems Ltd who continue to specialise in the pump market today.

Our engineering background means we tend to approach problems differently from most water treatment and pump distribution companies in that we look to supply the best product from an engineering point of view..

As Marshalls was working with booster pumps and borehole pumps in the 1970s, it was inevitable that we would be asked about filters and cleaning the water on Private Water Supplies (PWS).

Being engineers we looked for new and effective treatment solutions to the problems of iron, manganese, colour, pH and particulates and we became more and more involved throughout the late 70s and early 80s. During the mid 1980s the registered trade name CleanStream® was born as an umbrella under which all our water treatment products are catered for.

CleanStream continued to grow and the range grew larger and larger with ever more complex problems being solved. To date we have supplied equipment for, or installed, well in excess of 10,000 water treatment plants ranging from a simple tap filter to an entire village scheme.

Industrial, commercial or domestic, we have experience in all applications, large or small, and we have the right solution for your problem.

CleanStream products can be found in thousands of houses up and down the United Kingdom as well as hundreds of household names in the industrial and commercial sector.
