Natural Resources

Natural resources encompasses everything from protection of open space to the quality of our air and water. Preservation and conservation of natural resources helps protect the health of Nashua's people, provides healthy habitats for animals, and creates valuable recreational opportunities.

Water Quality

Combined Sewer System Overflows

Combined sewer systems are sewers that are designed to collect rainwater runoff, household sewage, and industrial wastewater in the same pipe. During periods of heavy rainfall, the amount of wastewater in a combined sewer system can go beyond the amount the system can take, causing overflows of dirty, untreated wastewater into nearby water bodies. Reducing overflows is a key strategy in maintaining the quality of Nashua's water.

Conservation Easements

What is a Conservation Easement?

A conservation easement is a legally binding agreement that prevents development on a piece of land forever, protecting the land for specific conservation values, such as water quality or wildlife habitat, while still providing economic benefits for the area in the form of jobs, economic activity and property taxes.
