As the population in the town of Newbury, New Hampshire, grew, facility operators began detecting elevated levels of nitrogen in the effluent and groundwater. This sparked the need for an update to the Blodgett Landing Community Treatment Plant. The Blodgett Landing plant is a 50,000-gpd facility that uses passive treatment, denitrification and dispersal to purify the town’s wastewater. The facility’s limited budget required that any treatment plant upgrade solution be effective and affordable both in upfront cost and ongoing operations and maintenance expenses. Additionally, Newbury’s economic dependence on recreational tourism required a solution that would preserve the area’s natural beauty.

Solution

Several options were explored before town officials contacted Presby Environmental for help. Presby recommended replacing the existing sand filter configuration with a Presby Enviro-Septic system. The system’s compact size and low maintenance requirements made it ideal for the Newbury system and the approach complements the existing Imhoff tank and recirculation.

Result

The Enviro-Septic pipe utilizes passive filtration and naturally occurring soil microbiology, eliminating the use of harmful chemicals or an external power source. The water treatment process is 100% green, enabling Newbury to protect its natural resources. The system also performs well in varying climates  — including freezing temperatures in colder months. The Enviro-Septic product is also a proven technology for removing up to 99% of contaminants, including fecal coliform, TKN, TN, TSS and BOD.

Presby Environmental is a wholly owned subsidiary of Infiltrator Water Technologies, a leading manufacturer of products for the decentralized water and wastewater industries. Presby manufactures the Enviro-Septic, Advanced Enviro-Septic and other wastewater treatment technologies.
