All building sewers shall be constructed in compliance with the Oregon Plumbing Specialty Code, except where higher standards apply within the utility code. (Ord. 15-05 § 2, 2015)
13.44.020 Permit – Required for sewer work.
No unauthorized person shall uncover, make any connections with or opening into, use, alter or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the city engineer. (Ord. 15-05 § 2, 2015)
13.44.030 Permit – Classes designated – Application.
A. There are two classes of building sewer permits:
1. For residential and commercial service;
2. For service to establishments producing industrial wastes.
B. In either case, the owner or the owner’s agent shall make application on a form furnished by the city. The permit application shall be supplemented by any plans, specifications or other information considered pertinent, in the judgment of the city engineer. No permit shall be issued until all required fees have been paid. Permit fees shall be established and revised by council resolution. (Ord. 15-05 § 2, 2015)
13.44.040 Costs of installation and connection.
All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. It shall be the responsibility of the owner, lessee or occupant of a building to maintain the building sanitary sewer or private collection system in a free-flowing and watertight condition, from the structure served to the public sewer. All existing private sewers shall be maintained in a safe and sanitary condition. (Ord. 15-05 § 2, 2015)
13.44.050 Cleanout specifications.
At the connection with the public sewer and the building sewer, there shall be a cleanout of the same material as the service connection pipe furnished by the owner. The cleanout shall extend vertically to within six inches of the finished ground surface and shall be sealed with an approved cap or plug. This riser shall be used for inserting a test plug for water or air testing the building sewer, and as an auxiliary cleanout. Backfilling around the riser shall be done in such a manner as not to damage the pipe. (Ord. 15-05 § 2, 2015)
13.44.060 Separate sewers for each building.
Every building sewer shall be separate and independent of any other building, whether connecting to a public or private sewer. (Ord. 15-05 § 2, 2015)
13.44.070 Private sewer restrictions.
Private sewer lines shall only be allowed where the building or buildings affected are located on a single parcel of land. Private sewers shall be subject to the same design and construction standards as public sewers of the city, and shall be subject to complete review and approval by the public works director. (Ord. 15-05 § 2, 2015)
13.44.080 Leaks and extraneous discharges – Monitoring procedures.
A. New and existing private sewers, building drains and building sewers will be monitored for leaks or discharges of extraneous water. This monitoring may take the form of, but is not limited to:
1. Direct visual observation;
2. Indirect measurement;
3. Tele-inspection; or
4. Air or water pressure tests, smoke tests, or exfiltration tests.
B. If, in the opinion of the public works director, such monitoring shows a sewer to be defective, no further proof is needed for the director to require the sewer to be repaired to current standards.
C. Existing sewer exceeding a maximum allowable infiltration/inflow rate of more than 300 gallons per day per single detached living unit, or 1,200 gallons per acre per day, are deemed unsafe and unsanitary and shall be repaired.
D. Those users who do not comply with these infiltration/inflow regulations shall have a period of time, as determined by the public works director, but not to exceed six months, to reach compliance with the regulations. (Ord. 15-05 § 2, 2015)
13.44.090 Capping and inspection prior to abandonment.
A. Before a moving or wrecking permit is allowed to be issued, evidence must be presented showing the sewer has been properly capped and inspected. No exceptions will be allowed. All building sanitary sewer shall be capped at the public main in an approved manner by the applicant or the applicant’s contractor, and inspected by city forces prior to closure of the excavation.
B. Exception. If adequate proof can be given showing a sewer service is in usable condition and is to be reused, the inspector may allow the service to be capped at the property line. It is the applicant’s responsibility to ensure that no other structure is connected to the sewer service being abandoned. If the line abandoned is serving more than one structure, a service connection for the structure(s) still using the service must be provided. If the city engineer determines that capping at the main will cause undue hazard to the public, or if a street has been recently resurfaced, a variance to this section may be granted to require that the sewer be capped as close to the main as practical. The city will chemically seal the service at its expense. (Ord. 15-05 § 2, 2015)
