Over 90% of the water pollution problems in New Hampshire are caused by stormwater runoff from the roads we travel, the buildings and parking lots we visit, and even the homes in which we live. Every single property has the potential to contribute to water pollution. Every property owner can also be part of the solution to water pollution. NHDES created a comprehensive guidance document and a hands-on voluntary program to assist New Hampshire home and small business owners in reducing water pollution.
- New Hampshire Homeowner’s Guide to Stormwater Management Do-It-Yourself Stormwater Solutions for Your Home: A guidance document to help residential homeowners better manage stormwater on their properties. It can also be used by communities as an outreach tool to encourage better stormwater management on private properties.
- Soak up the Rain New Hampshire Program: A voluntary program managed by NHDES with the goal of protecting and restoring clean water in the state's lakes, streams, and coastal waters from the negative impacts of stormwater pollution. The program works with local partners to provide resources and technical assistance to help homeowners install rain gardens, rain barrels, dry wells, and other practices to manage stormwater on their properties.”

Do-It-Yourself Stormwater Solutions for Your Home
The New Hampshire Homeowner’s Guide to Stormwater Management Do-It-Yourself Stormwater Solutions for Your Home was developed to help residential homeowners better manage stormwater on their properties. It can also be used by communities as an outreach tool to encourage better stormwater management on private properties.
This practical guide provides fact sheets with step-by-step instructions to install do-it-yourself stormwater treatment practices, such as dry wells and rain gardens. These stormwater treatment practices, also called low impact development (LID) practices, help protect nearby streams and ponds from stormwater pollution, and help reduce flooding, create wildlife habitat, recharge groundwater, and conserve water resources.

New Hampshire Residential Loading Model **BETA**
The New Hampshire Department of Environmental Services has created a modeling tool for homeowners to estimate their nutrient footprint call The New Hampshire Residential Loading Model.
This model is based on the Center for Watershed Protection’s Runoff Reduction Method. It is designed for property owners to estimate the loading of nutrients, specifically phosphorus and nitrogen, running off of their properties. This model can be used to:
- Calculate a property’s phosphorus or nitrogen “footprint”, which is how much phosphorus or nitrogen a property contributes to the watershed in which it is located.
- Calculate the benefit of installing LID practices on a property.
- Compare the existing and planned future conditions of a property with different stormwater treatment scenarios. For example, to estimate the impact that building a garage or the impact that constructing a rain garden on your property would have on nutrient loading.
- Determine if a property meets a targeted nutrient goal or nutrient reduction for its watershed, if a target goal or reduction has been set.
