Bellevue — Ch. 8 Buildings, Housing, and Construction § 8-84
Drainage
Operative Text
Drain outlet fittings from a private swimming pool or spa shall not be connected to a sanitary sewer line. Drainage shall be by gravity or by pumping or siphoning out into the top of a basin or sump located ahead of the storm drain sewer so as not to create a nuisance to adjacent properties or to the curb or gutter located along an adjacent street.
Bellevue § 8-84 prohibits connecting private swimming pool or spa drain outlets directly to the sanitary sewer system. Instead, pool and spa drainage must flow — whether by gravity, pump, or siphon — into a basin or sump that feeds into the storm drain system. The rule also requires that this drainage process not create a nuisance for neighboring properties or cause overflow onto adjacent street curbs or gutters.
Plain English — not legal advice.
Under Bellevue § 8-84, compliant property operators ensure that any private swimming pool or spa is plumbed so that its drain outlets discharge into a basin or sump connected to the storm drain, never to the sanitary sewer. Operators generally verify that the drainage method — gravity flow, pumping, or siphoning — is configured to contain water on-site before it reaches the storm system, preventing runoff onto neighboring lots or street gutters. Routine inspections of drainage equipment help confirm that the setup continues to meet the standard set out in § 8-84.

Bellevue § 8-84 establishes that pool and spa drainage at a rental property must be routed away from the sanitary sewer and managed so it does not create a nuisance for neighbors or the adjacent street. If a tenant observes that pool or spa drainage appears to be improperly connected or is causing flooding or nuisance conditions, they may report the concern to the City of Bellevue's code enforcement or building department. Tenant-rights organizations can also help residents understand how a violation of § 8-84 might relate to habitability or property-condition standards.
