A Safe Septic System for Nearby Waterways

Plumbing and heating expert Richard Trethewey walks us through a system that was designed for a home built near a pond and the ocean

Due to its proximity to a pond and the ocean, our Westerly Ranch House project required a septic system equipped with advanced secondary treatment. The purpose of the treatment is to reduce the ammonia and nitrogen that typically leaches into the ground downstream from the tank. Combined with a traditional septic tank, this system converts nitrogen to gas which is vented through the roof of the house. Our plumbing and heating expert Richard Trethewey explains more here.
