PART 1 - DESIGN AND CONSTRUCTION REQUIREMENTS

1. GENERAL The City of Vancouver has adopted the submersible lift and pump station described herein as its standard pump station design. The Contractor shall contact S&B Inc. for the SCADA System requirements and integration early in the design process.

Telephone: 425-644-1700 Fax: 425-746-9312 Email: [email protected] Customer Support: [email protected]

Engineers designing pump stations for developments are required to contact the Engineering Division at the beginning of the process to discuss the preliminary design with the Engineering Division and the Operations Division. The Developer shall furnish all mechanical and electrical equipment required for the complete submersible pumping station including two (2) submersible pumps with rails, a third spare pump, flush valve, internal piping, chemical feed station, MCC (wired for a triplex pump setup, see SCADA requirements), level control system, check valves, SCADA, and standby power. Stations with large flows may require three (3) pumps and a fourth spare. Pumps shall be Flygt Pumps supplied with protection relay MiniCas 120 part # 14-40 71 29, or pre-approved equal. Developments located outside of an existing pump station’s original contribution area that propose new flows to the station are required to complete a station operation and capacity analysis. Developments are required to upgrade all related station components to meet current design standards. A preconstruction meeting shall be held prior to beginning construction on any station. Contact the City Construction Manager at (360) 487-7750 to arrange this meeting.

2. SITE CONDITIONS Each pump station shall be placed on a separate lot dedicated to the City of Vancouver. A deed is required to transfer parcel ownership. The lot shall have direct access from the public street, vehicle staging, and a security fence. Design the pump station site to facilitate access and maintenance. Maintenance vehicles must be able to pull directly to the wet well. A minimum turn radius of 46 feet is required to negotiate turns. A turning template is available on the City’s website with the Transportation standards. Standard Plan PS-1.1 shows minimum site plan requirements. The engineer shall use the plan as a guide and is also required to prepare a site-specific plan. Additional space may be required for



2

maneuvering at stations that access busy streets. Structure and other feature locations may also need to be moved to avoid conflicts. The City will also consider proposed modifications to the standard site layout and the electrical structure for aesthetic reasons. Submit such modifications for review prior to submitting development plans for review. Fencing shall be furnished and installed to WSDOT Type 3 L-20.10-03 standard plan, except as noted herein or shown on the plans. In addition, the fence shall be furnished with galvanized caps and extension arms. All fencing materials shall conform to WSDOT Standard Specifications section 9-16.1. Concrete curbing shall be placed at the base of the fence to isolate and contain drainage on the site. There will be no landscaping within the boundary of the pump station property. Exceptions to fencing, landscaping, and irrigation outside of pump station enclosure requirements may be granted for developments wishing to incorporate these elements into their overall site plan. Developers will be responsible for all landscape and irrigation maintenance.

3. SUBMITTALS The contractor shall submit six (6) sets of complete manufacturer's literature on all items of equipment proposed for use in the station. Submit to the City of Vancouver's Construction Services, 520 SE 155th Ave, (360-487-7750), for review and approval prior to ordering any equipment. Submittals shall include, but are not limited to, the following: pumps, including pump curves showing operating conditions and efficiencies; vaults; covers (hatches); chamber ladder; check valves; gate valves; air valves; solenoid valve; RPBA; Hot Box; chemical feed station; floats; Remote Telemetry Unit (RTU), Intrinsically Safe Relay Box (ISR) , Motor Control Center (MCC) including all components (SCADA, ultra sonic level control, flow meters, etc.); explosion proof & low voltage junction boxes ; automatic transfer switch; generator w/ fuel tank & battery charger.

4. CAPACITY CALCULATIONS The engineer shall submit design calculations for the sizing of the pump station. Stations shall be sized for build-out of the basin being served. The criteria used shall be that contained in the City of Vancouver’s Sanitary Sewer Master Plan. Use 75gpcd for residential flows and 800gpad for non-residential flows. The peaking factor is based on the following formula: PF = 2.63 - 0.26 ln (Qaverage

mgd). Inflow and infiltration allowances are specific to the basin. Contact the City’s Engineering Division for I&I allowance within the station’s basin.

5. PUMPS REQUIREMENTS Each pump in a duplex station shall be capable of delivering the expected peak flow of unscreened raw sewage against the total dynamic head (TDH) including static lift, pipe friction, and station losses. Each pump in a triplex station shall be capable of delivering half of the peak flow. If expected flows are not anticipated to reach peak values for several years, a proposal to initially install smaller pumps



3

or impellers will be considered. However, all piping and electrical components shall be sized for buildout. Each pump shall have a maximum allowable speed of 1,750 rpm. Each motor shall have the appropriate horsepower as indicated by the pump manufacturer. Motors shall be 3-phase. All openings and passages shall be large enough to permit passage of a three-inch (3”) diameter sphere and any trash or stringy material which can pass through a four-inch (4”) collection system. Service shall be 480 volts whenever possible. Confirm availability with Clark Public Utilities. A “spare” pump will be required for all stations. This spare pump will include the motor, power cable, volute, flush valve, and impeller. Submit pump curves for the proposed pumps including the Model Number, Series Number, Type, and impeller size.

6. PRE-SEDIMENTATION AND WET-WELL 6.1 Pre-Sedimentation Manhole Pre-sed manholes are required to intercept heavy solids (rocks) and floating materials (rags). Effluent piping assembly and float elevations are designed to pass liquids to the wetwell and to provide overflow. The pre-sedimentation manhole also provides working pump volume. Design the pre-sed manhole, effluent piping, hatch, and safety rail as shown on the Detail PS-1.9A. Account for pre-sed volumes in the pump design calculations. 6.2 Wet-Well The engineer shall design an appropriate wet well. Align inlets from pre-sed manhole perpendicular to a line drawn through the pumps. The minimum wet well diameter for a duplex station (with pumps smaller than 13.5HP) is eight feet (8’). Wet wells serving triplex stations or duplex stations with large motors shall be a minimum diameter of ten feet (10’). All metal components shall be 316 stainless steel. The contractor shall furnish and install the wet well according to the project plans and the City’s General Requirements and Details. Contact City Engineering offices for any wet wells greater than 30 feet deep. See Detail PS-1.9A & PS-1.9B. Prepare and include plan and profile views. Show and note all components. Show and note wet well wall and base thicknesses. Prepare and include flotation calculations if the wet well is to be placed in an area of high groundwater. The wet well shall be sized to accommodate the ultimate flows to be pumped. The wet well capacity shall be adequate to allow the pump motors to cycle at or above the minimum cycle times required by the given motor. This is dependent on the motor type, motor speed, motor horsepower, the shaft load, and the motor starter. NEMA guidelines can be found in the Energy Management Guide for Selection and Use of Single-Phase Motors, NEMA MG 11-1977 (R1997, R2001, R2007), (http://www.nema.org/stds/mg11.cfm#download). The engineer is referred to the Wastewater Pump Station Design Manual prepared by the Bureau of Environmental Services of the City of Portland, and to Chapter 26, Pumping Station Design Second Edition, Editor-in-Chief, Robert Sanks, for more detailed discussions of wet well sizing for constant speed pumps.
