The minimum size sanitary side sewer lime shall be four (4) inches. 4. Sizing calculations for the sewer ejector pump 5. Manufacturer's specifications for the sewer ejector pump and backwater valve L_1TEMP1BUILDINGIHAND.0UT 1CODESISANITWSTE]ECT W&DOC Revised 2/05 GENERAL INSTALLATION REQUIREMENTS The following regulations apply to single family dwellings and individual plumbing facilities that are not considered to be public use. For non-residential installation requirements refer to the end of this handout. A sewer ejector pump may be installed on discharge to a building side sewer line or building drain line. A sewer ejector pump discharge line shall not discharge directly into a sewer lateral or sewer main. Where the owner/applicant chooses to install the sewer ejector pump will determine the types of permits and inspections required. Factors that may play a role in the location are. the topography of the site, location of fixtures to be connected, ease of installation, etc. Wherever practicable, all plumbing fixtures shall be drained to the public sewer system by gravity. The permit for a sewer ejector pump is a special approval and shall only be granted when gravity flow cannot be established due to elevation of lowest drain relative to the City sewer_ Only those plumbing fixtures that cannot maintain a gravity flow may be connected to a sewer ejector pump. In all cases the sewer ejector pump shall be sized to handle all connected plumbing fixtures. DESIGN STANDARDS All equipment shall be UL listed and ICBOIIAPBMO certified, and be installed per the manufacturer's installation instructions, except for the externally mounted control panel, electrical power connections, gravity sewer inlet hubs and the pump assembly, which are installed in the field. Design flow rates shall be based on peak water demands of all fixtures flowing into the sewer ejector system as outlined -in Appendix A of the current adopted Uniform Plumbing Code. Exterior hose bibs should not be included in these calculations_ Prohibited Installations t Storm drains (including roof drains) and groundwater collection systems are not permitted to be connected to the sewer ejector pump. ♦ Sump pumps (pumps that transfer seeping groundwater from a foundation crawlspace or basement to a location outside the home above grade) are not permitted to be connected to the sewer ejector pump. DEFINITIONS Backwater Valve: When applicable, protection from backflow of sewage is required by installing an approved type backwater valve (also called backwater device). Building Drain Line: That portion of sanitary sewer line under the house (under slab or within; the crawl space) or within two (2) feet of the exterior wall of the building. This piping is typically Schedule 40 ABS or Schedule 40 PVC DWV. Building Side Sewer Line: That portion of the sanitary sewer line located more than two (2) feet from the exterior wail of the building to the sewer stub at the property line. This piping is required to be ductile iron pipe or Polyvinyl chloride SDR 35 (PVC) pipe. LATEMP\BUILDING\HANDOUT ICODESISANITWSTEJECT B76 -DOC Revised 2/05 Ejector Pump: Ejector pumps are used to transfer domestic sewage from waste lines below the elevation of the sewer main to higher sanitary lines in the house or yard_ Typical plumbing fixtures connected to an ejector pump are toilets, bathtubs, showers, sinks, washing machines, etc. Sewer Lateral: That portion of the sanitary sewer line from the private property line to the sewer main in the street. NON-RESIDENTIAL INSTALLATIONS Pursuant to Section 714.9 of the Uniform Plumbing Code, interior sewer ejector pumps shall be dual pumps when serving any public use occupancy. Public use is defined as plumbing fixtures that are not intended for the private use of a family or an individual. Dual pumps or ejectors are required on public use installations and shall be arranged to function independently in case of overload or mechanical failure. The lowest inlet shall have a minimum clearance to two (2) inches from the high water or starting level of the sump. Public use pumps shall have an audio and visual alarm, readily accessible, that signals pump failure or an overload condition. All other permit requirement provisions shall apply as referenced earlier in this handout. Peer review may be required.. OTHER PERMIT INFORMATION Side Sewer Permit: Extension, alteration of, or connection to, the building side sewer line shall be completed in accordance with the terms of a Side Sewer permit (fee $95). Inspections for this portion of the piping are performed by the City Engineering Inspector (425-771-0220 ext 1326). Plumbing Permit: Extension, alteration of, or connection, to the building drain line, and/or installation of an ejector pump inside the Douse or within two (2) feet of the exterior wall, shall be completed in accordance with a Plumbing Permit under the current edition of the adopted Uniform. Plumbing Code. Additional fees will be required if new fixtures are installed or existing fixtures are relocated. Inspections for this portion of the piping are performed by the City Building Inspector (425-771-0220 ext 1333). *Note, it is possible that both a Side Sewer Permit and a Plumbing Permit could be required on some projects. **Note, if it is discovered that the side sewer line is cracked or damaged, thereby allowing infiltration of rain or ground water, that piping shall be required to be immediately repaired with a side sewer repair permit. ***Note, all contractors doing work in the City must obtain a City business license.
