Small-scale wastewater treatment

WRS has worked with small- and medium-scale wastewater treatment during many years. Our services include information, education, planning and design of treatment facilities.

We have thorough experience about technologies suitable for single households as well as small municipal treatment facilities. Among our reference objects are treatment facilities with urine diversion, blackwater separation, sand filters, compact filters with artificial filter media, spray filters and reactive filters for the adsorption of phosphorous.

Our references also include bio bed treatment systems, drainable precipitation ponds and energy crop irrigation with wastewater.

The planning tool Open wastewater planning, developed by WRS, in association wiyh VERNA, assists individual house owners as well as municipalities in finding the right wastewater solution.

WRS works with knowledge transfer on robust and ecological wastewater treatment in several countries, including Estonia, Latvia, Lithuania, Poland, China and South Africa.
