Enterprise Stand-by Generator Replacement Location:

Numerous Sewer Lift Stations

CIP: 378-14

Date: 8/17/2026 Bid Site Walk: 8/26/2026 Bids Due Date: 9/10/2026

Bids to be submitted to: OWASA (jkucera@owasa.org)

Scope of Work

GENERAL SCOPE: As part of an enterprise wastewater lift station stand-by generator replacement program, OWASA is soliciting RFP for replacement of 10 diesel stand-by generators along with ancillary electrical services to facilitate more streamlined operations and maintenance. The scope of work for this includes procurement of the specified generators, permitting, installation of generator, installation of a new automated transfer switch if deemed necessary by the bidder, start-up testing and commissioning. Additional ancillary services have been requested and include installation of an electrical docking station to both facilitate an auxiliary generator connection should the stand-by generator be down and a point for attachment of a load bank.

At each lift station the work includes:

Installing an appropriately sized docking station that will allow both efficient and quick connection of a portable emergency generator in the unlikely event the stand-by generator is down; and periodic connection of a load bank to the run the stand-by generator at least 80% load to prevent wet-stacking. Attachment 1 provides the Trystar variant of the type of docking station, but contractor may propose an equivalent if it performs the same function.

Contractor shall propose and elaborate on provisions for limited SCADA integration that will minimally include: Generator Status, Automatic Transfer Status, Fuel tank levels and power monitoring capabilities. To support this contractor shall articulate in the proposal how this will be provided (i.e. discrete contacts, analog signals, Modbus interface…etc.). OWASA is not looking for actual SCADA integration as this will be performed by others but looking for what inputs are readily available with proposed standard generator sets so that we may better evaluate the proposals.

Contractor is expected, as part of the proposal, to plan work to:

1. Remove current fuel from the existing generator, temporarily store on site, and then use that fuel in the new generator as well as “top off” the tank, if necessary, with fresh diesel fuel as recommended by the manufacturer. If there is excess fuel then Contractor shall notify OWASA and OWASA will remove the rest. Contractor shall provide the volume of fuel storage they are providing with the generator along with the anticipated hours it is expected to last at operational load.

2. Each generator provided shall come with a sound attenuating enclosure.

3. Contractor shall remove the former genset from the site and deliver it to a laydown yard to be specified by OWASA. The farthest it would be is at the OWASA quarry reservoir lay down yard located adjacent to 1807 NC-54 near the intersection of Bethel Hickory Grove Church Rd. (approximately 9 miles from Mason Farm WWTP).

The scope of work is split into 2 phases and indicate which generators are to be replaced and when:

Phase I: Anticipated to be completed between September 2026 and December 2027

Chapel Hill North PS (100 kw) Countryside PS (100 kw) Sherwood Forest PS (40 kw) Manning Drive PS (40 kw) Meadowmont #1 PS (40 kw) Rangewood PS (40 kw) Meadowmont #2 (25 kw)

Phase II: Anticipated to be completed between January 2028 and December 2028)

Heritage Hills PS (125 kw) Lake Ellen PS (80 kw) Oaks #3 PS (50 kw)

Additional details on the requested work are summarized on Attachment 2.

PERFORMANCE REQUIREMENTS:

General Generator Specifications

The Contractor will furnish and install a diesel fueled engine-generator sets that are to be used to provide standby power to operate the pump station in the event of an interruption of power from the utility. The set will be the product of one manufacturer, will be covered by a factory warranty and will be furnished through an authorized dealer responsible for warranty parts and service in the surrounding area of OWASA area for all equipment supplied under this specification. The individual gen sets will be new and Underwriters Laboratories, Inc. approved and labeled, where applicable.

The sets will be rated at least the kilowatt rating as listed on Attachment 2 @ 0.8 power factor for standby power service. The set will be capable of delivering full rated power from 0 degrees to 100 degrees F with all operating accessories.

The following information will be submitted for approval prior to manufacture/procurement of the unit:

1. Certified drawings of the unit and its foundation requirements, including the location and type of all external connections.

2. Complete literature describing all components to be furnished. Include a statement of the production status of all equipment to be furnished.

3. The name and location of authorized parts and service facilities.

Three full sets of documentation including operation and maintenance manuals, circuit wiring diagrams, commissioning/fault finding instructions, overhaul or shop manuals, and repair parts manuals will be provided with the engine-generator set. One set will remain with the engine-generator set and the other two will be turned over to OWASA.

The proposer shall describe in their proposal general information on each of the gensets such as:

Number of cylinders, engine displacement and operating speed Types of diesel fuel required or can be used with the unit Engine starting power (battery system) and how it will maintain charge.

The fuel tank system that will be supplied and related spill prevention features. The proposer shall articulate the type of fuel tank and show how the capacity meets the required run times as indicated in Attachment 2.

The proposer shall describe any value-added options in the proposal that serve maintenance efficiency and reduction in on-site maintenance time.

The proposer shall indicate how the unit provides minimal signals to be captured by OWASA’s SCADA system at each lift station. Minimal inputs should include fuel level, genset running, …………………..

The alternator will provide power at the voltage, phase and wire configuration as provided on Attachment 2. Frequency regulation will be 60 Hz +/- 0.8% for a constant load from no load to 100% load. Voltage regulation will be +/- 1.0% from no load to 100% load. The alternator will be a self-exciting, self-regulating, brushless type with fully interconnected damper windings. The alternator will be provided with a fully rated cooling system and sealed-for-life bearings. Alternator insulation will be class H.

The engine-generator set will be mounted on a heavy-duty steel base frame. The complete engine/alternator assembly will be enclosed in a sound attenuating enclosure rated for minimum 75 dba at 25 feet from the unit.
