Business/Residential Information

In 2001, Pennichuck Water Works developed informational brochures regarding pollution prevention for agricultural and automobile industries within the drinking water supply watershed, as well as non-point source pollution resulting from residential lawn care. A series of informational videos detailing the impacts of stormwater and ways to reduce stormwater pollution were also created. All of these materials are included below, along with guides for completing DIY stormwater improvements at home or at work.
