What are the sustainable wastewater solutions for Baltic Sea coastal tourist areas

The publication written by NURSECOAST-II partner Jari Heiskanen from SYKLI Environmental College, addresses one of the region’s most pressing but often overlooked environmental challenges: the surge in wastewater during tourist season. In many small coastal villages, the summer population can double, triple, or even increase tenfold – putting enormous pressure on wastewater treatment systems designed for year-round residents.

When small-scale and on-site systems are overloaded, untreated nutrients and bacteria can reach the Baltic Sea, contributing to algae blooms, poor bathing water quality and damage to coastal ecosystems. The consequences extend beyond the environment, affecting public health, tourism and local economies.

This document draws on pilot studies, Sanitation Safety Planning (SSP) risk assessments and practical experiences gathered across Baltic Sea countries through the NURSECOAST-II project, complemented by national guidelines and expert knowledge. Written in clear, accessible language, it covers sustainable and cost-effective wastewater solutions suited to the realities of small communities, with a focus on climate resilience and environmental protection.
