Source

Section 1

  1. No city or town may prohibit the installation of sewage grinder pumps for new residential buildings that:

    1. Are located below grade of a public sewer line;

    2. Are connected to a low-pressure sewer system;

    3. Are located at a distance from a public sewer line that gravity alone cannot effectively move wastewater to the public sewer system;

    4. Must move wastewater vertically;

    5. Are located in a new residential community where geologic site conditions or excessive topography cannot support the expense of a gravity sewer system.

  2. For purposes of this section:

    1. "Sewage grinder pump" means a system connected to a residential building's wastewater system that collects, grinds, and pumps residential sewage into the public sewer system.

    2. "Low-pressure sewer system" means a wastewater system that requires pressure from sewage grinder pumps to transport wastewater.
