  • Filter bed performance is compromised when moss growth is prevalent.

  • Essential to have a solution suitable for use around people and waterways.
How we helped

Foamstream allowed South West Water to move away from costly, time consuming manual labour practices which were traditionally the way to manage unwanted vegetation growth on the percolating and de-nitrifying filter beds.

By reducing the amount of time needed to treat the filter beds, operators were able to spend more time on other parts of the process.

It was a critical consideration to have an environmentally friendly and sustainable solution when working with the water course, Foamstream fitted this requirement perfectly and allowed the operators to easily and simply treat the filter beds on site.

Foamstream was also used to treat moss and algae around site walkways and on surfaces to help reduce slip and trip risks to employees and visiting personal.

Overall, Foamstream helped reduce costs for South West Water through better allocation of labour, time and reducing the number of times each site needed to be treated.
