Cape Cod faces two connected challenges: Nitrogen pollution from conventional septic systems, and a housing affordability crisis worsened by wastewater constraints.

The majority of Cape Cod’s nutrient pollution comes from urine. Sewer expansion is often proposed as the only solution, but it can take years to build, come with high costs to towns, homeowners, and developers, and still may not remove all nitrogen from effluent.

Fortunately, practical and cost-effective wastewater options exist that could complement or replace conventional approaches.

This site was built to help you understand these alternatives and how they might work for our homes and communities.
