Small-scale local solutions to reduce nutrient load into the Baltic Sea

The project is aimed at the reduction of nutrient load into the Baltic Sea through the introduction of small-sale wastewater treatment solutions in general and dry eco toilets for individual households in particular. Within the project, 3 pilot demonstration toilets will be established for local communities situated in the Lujskij and Lomonosovskij rural districts on the southern shore of the Gulf of Finland. The most important activities of the project concern public awareness raising for nutrient pollutions and methods for reducing them.

Situation and background

The eutrophication in the Gulf of Finland is still increasing. Sufficient amounts of nutrients originate from diffuse sources such as wastewater from small settlements or individual houses/dachas as well as organic waste and fertilizers from agriculture. More than 3,5 thousend gardening communities exist in the Leningrad oblast/St.Petersburg area and about 2 million people reside there 60-90 days per year. Those are hardly informed about simple solutions and everyday practices, which can help to reduce nutrient load to the natural waters.

Project activities and effects


 The project raises public awareness of opportunities for the reduction of nutrient load from rural households and small-scale agriculture. It introduces local solutions via practical installations on pilot sites and it inspires local policy developments for widening pilot solution applications.


  • Info-kit on challenges and solutions, dissemination on the web, multi-stakeholder seminars
  • Public river watch – investigation of N and P
  • Installation of eco-toilets on two pilot sites
  • Approbation, demonstration of eco-toilets for potential followers and media
  • Analytic report on the project results/prospects
  • Map on nutrient pollution sources
  • Round table on policy development
  • Final press conference

Expected Results:

  • Awareness raised, thousands of people are informed.
  • Pilot ecotoilets&composters are established and functioning as really working facility on the demonstration sites.
  • Many hundreds visitor use pilot installation and make sure in its benefits, became interested in its application in their households.
  • Causes of nutrient pollutions became visible (Map, Analytic report), decision makers are informed about successful approbation, convinced of importance to promote these measures.
