Pipelife Finland: Pisara purifying holiday cottage wastewater
It is estimated that wastewater from sparsely populated areas is the second largest source of load to lakes and rivers in Finland.
− Bacteria and diseases spread through wastewater, which also contaminate wells, in the worst case groundwater sources, and eutrophicate lakes and rivers, says Marko Heikkinen, Marketing Manager of Pipelife.
In an urban environment, household water and washing water are treated in onsite wastewater treatment systems, whereas in sparsely populated areas each property owner is personally responsible for purifying their wastewater.
It was noticed in Pipelife’s product development that consumers and installation partners were looking for novel solutions for the treatment of wastewater in holiday cottages and private houses. This resulted in the idea about the Pisara greywater filter. The filter is capable of processing as much as 500 litres of domestic and washing water per day by absorbing it through biofilter discs. The purification process does not require electricity or chemicals.
− Pisara was developed for properties where installation conditions do not allow the use of onsite wastewater treatment systems or the use of underground systems. The system is small and can be transported on a trailer, Heikkinen says.
There is an urgent need for a new type of greywater filter, as there are more than 150 000 holiday sites in Finland that lack effective wastewater treatment systems.
