This bill introduces new regulations regarding the installation of sewage grinder pumps in new single-family residences across various jurisdictions in Washington State, including cities, counties, water-sewer districts, and public utility districts. Specifically, it prohibits these entities from banning the installation of sewage grinder pumps under certain conditions, such as when the residence is below the grade of a public sewer line, connected to a low-pressure sewer system, or when gravity drainage is not feasible. The bill also stipulates that the property owner is responsible for the maintenance and repairs of the sewage grinder pump, although the local authority may choose to take on these responsibilities.

Additionally, the bill defines key terms related to sewage grinder pumps and low-pressure sewer systems, ensuring clarity in the implementation of these regulations. The provisions emphasize the importance of adhering to the utility provider's sewer system plan and include a mechanism for the sewer provider to perform necessary repairs if the property owner neglects their maintenance duties, allowing them to invoice the owner for the costs incurred. Overall, the bill aims to facilitate the use of sewage grinder pumps in residential construction while delineating responsibilities for maintenance and compliance.
