VillageWaters

The Interreg project Village Waters produced comprehensive knowledge about technical solutions for cleaning waste water in the countryside and successfully made it available to municipal officials, home owners and companies - now they can improve the waste water treatment and comply with EU directives also where large waste water treatment facilities are missing.

 

THE CHALLENGE

Nutrient pollution from scattered dwellings has been underestimated

Waste water treatment in cities has been improved considerably over the past 30 years, while the countryside did not receive much attention. On the EU level, the Water Framework Directive from 2000 and the Urban Waste Water Treatment Directive from 1991 require that waste water from households is treated to remove nutrients before their release to the environment. The national implementation of these directives differs. In some countries, there is a legal obligation in place for all households to clean their waste water. In other countries such as Estonia, Latvia, Lithuania and Poland there is to date no legal obligation for nutrient removal from waste waters for small dwellings, e.g. of less than 2000 inhabitants. The Baltic Sea Environmental Protection Commission HELCOM noted that nutrient pollution from scattered dwellings has been underestimated.

 

People in rural areas need access to information to make sound decisions

It can be anticipated that in the next 5-10 years, the focus will shift from cities to villages, and that all countries will have to become more active to improve the waste water treatment also in the countryside. There is no lack of technical solutions for cleaning waste water on small scales. However, it has been difficult for small municipalities and home owners to select cleaning facilities that fit their local needs and are affordable because the information about such cleaning systems is scattered and usually not directly comparable.

 

HIGHLIGHTS

Life Cycle Assessments reveal all information needed

In the Village water project, researchers from Finland with support of scientists from Poland, Latvia, Lithuania, and Estonia collected comprehensive information about more than 100 different waste water treatment systems from manufacturers, studies and own experiments. They carried out in depth life cycle assessment for each of them. A life cycle assessment reveals not only the costs of purchase, installation and annual maintenance. It provides detailed information, about the cost-effectiveness in terms of removing nutrients, about the greenhouse gas emissions generated and many more relevant parameters.

 

Municipalities test cleaning solutions and pin down their information needs

Nine municipalities tested different technologies available in their respective local settings, from septic tanks to soil infiltration: in Kolgaküla and Valkla (Estonia), Gennarby and Nurmijärvi (Finland), Ainaži and Svētciems (Latvia), Leitgiriai (Lithuania), as well as in Krynica-Zdrój and Sokoly (Poland). The incoming waste water, the outgoing water and the sludge were analysed with respect to nutrients and bacteria they contain, i.e. how efficiently the solutions worked in practice. Their experience is compiled in a report. In each municipality, researchers and municipal officials held meetings with the village communities and collected input on which information they need.

 

Municipalities, home owners & trainers get better information at a few clicks

All information about all technologies currently on the market was compiled in the interactive online Wastewater Solutions Information Tool. The tool now helps municipal staff who issue environmental permits, e.g. in Finland, to assess if certain solutions can be permitted or not. In addition, manufacturers of such solutions compare treatment systems and can easily identify how good their technologies are and at which stages of the life cycle they need to focus their product development to provide more efficient systems in the future. The tool is already used in vocational training for waste water managers in Finland. Within the project platform BSR Water, the tool is also integrated into the Smart Water Hub, on online platform for smart solutions and lifelong learning in water management.
