PART 1: GENERAL
1.1 Description
Project Name: Doug’s Lynnwood Mazda – “Parking Lot” Stormwater Lift Station
Location: Edmonds, WA
Date: 12/20/17
The following are a few design consideration that Romtec Utilities would like to be clear on:
• Romtec Utilities design this lift station as a duplex (two pump), redundant, alternating system to meet the
required pumping rate of 12 GPM. Each pump is capable of pumping 12 GPM.
• Romtec Utilities is suggesting the use of a 1” SCH 80 PVC force main.
• Romtec Utilities is suggesting that the discharge point for the lift station be 3’ below grade. This allows for
access to the in-well valves and provides additional head to help with the pump selection.
• Romtec Utilities has configured this lift station to operate on 120V/Single phase power
• Romtec Utilities is proposing the use of non-explosion proof pumps for this application.
• Onsite backup power generator to be supplied by the project owner, not Romtec Utilities.
Please review the scope of products and services defined below:
1.2 Overview of Scope
A. Romtec Utilities work shall include designing and supplying the piping, mechanical, and
appurtenances within and adjacent to the wet well as a complete, pre-designed, packaged pump
station as described herein. Romtec Utilities shall be solely responsible for proper integration, supply,
performance, and warranty of all package pump station components provided by Romtec Utilities.
B. Romtec Utilities will provide complete submittal documentation for review including mechanical and
electrical component drawings, data sheets and the layout of the Romtec Utilities supplied
components on the customer supplied AutoCAD site plan.
C. Romtec Utilities will work with the site engineer, reviewing entity, and all other associated parties
through the review, comment, and approval process for the pump station.
D. Romtec Utilities will manufacture and deliver the pump station as described below to the job site for
the contractor. A representative of Romtec Utilities will be present the day the pump station is
installed to provide technical advice to the contractor.

G. The installing contractor is responsible for pump station installation. Contractor work will generally
include site preparation, excavations, backfill, compacted foundation construction, and all mechanical
and electrical component installation.
H. Romtec Utilities does not perform any construction at the site.
1.3 Pump Station Design and Submittals
A. Romtec Utilities will provide the complete lift station design and submittal package for the pump
station for review and comment by the reviewing entity. Romtec Utilities’ submittal will include the
complete lift station design for all structural, mechanical, electrical, and communication aspects of
each pump station.
B. Romtec Utilities will provide the Scope of Supply and Design Submittal in electronic form and we
will work with all parties through review and approval by the reviewing entity.
PART 2: PRODUCTS
2.1 Prefabricated Wet Well and Mechanical
Romtec Utilities will prefabricate the wet well structure and associated interior wet well
mechanical equipment prior to shipment to your jobsite. The following aspects are included as
part of the prefabricated wet well:
A. Romtec Utilities will supply the 4’ diameter precast wet well including the top slab with hatch, base,
and all associated risers.
B. The hatch will be H-20 traffic rated and will include a mushroom cap vent.
C. Each cored hole shall have an associated Kor-N-Seal for each particular pipe size entering and exiting
the wet well to ensure no water leakage outside the wet well.
D. Sealant and tapecoat shall be provided for each section of the wet well to ensure no water leakage
through the joints.
E. Romtec Utilities will provide alignment brackets for proper orientation during installation.
F. Romtec Utilities will be supplying all in-well 1” SCH 80 PVC and 1” flexible plastic discharge piping
and fittings from the pump discharge elbow up and through the wet well structure.
G. The approximate wet well depth from the rim to the base is 16’.
H. The wet well will need to be assembled on site by the installing contractor.
I. The heaviest section is the base slab, at 5,000#.
J. Romtec Utilities will supply a PVC ball and check valves that will be installed in the wet well.
2.2 Pump Package

Romtec Utilities will be integrating the pump package into the wet well structure and control
panel prior to shipment to the jobsite. The following are the associated pump items Romtec
Utilities will be supplying and integrating:
A. Romtec Utilities will supply (2) 1/3HP Ebara submersible pumps with all associated piping, stainless
steel brackets, stainless steel lifting slings, and cord grips.
B. These pumps will be freestanding and will not be fix to discharge elbows or a guiderail system.
C. The pumping rate will be 12 GPM at 17’ TDH.
D. The pumps have been quoted with 20’ power cables.
Note: To meet the required pumping rate of 12 GPM, the operational valves may need to be
used to “throttle” the flow. Romtec Utilities will not supply a pump smaller than the
proposed 1/3HP Ebara pump.
2.3 Level Control System
A. Romtec Utilities is supplying and integrating all in well level sensing for the pump station. This
includes four (4) floats as the level sensing for the pump station.
B. Romtec Utilities will configure the pump station controls to operate on the specified level sensing
devices, and set the levels of the supplied devices at the time of pump station start-up and testing.
2.4 Control Panel
A. Romtec Utilities is designing and supplying the control panel and associated field devices for the
pump station. The control panel will be prewired, factory tested and UL listed.
B. The control panel will be configured with a logic relay controller configured for duplex operation and
will be housed in a NEMA 4 painted steel enclosure. The control panel will have a ‘dead front’ for
separation of operator and electricity.
C. The control panel and pump station are configured for 120V, single phase power.
2.5 Delivery and Installation Services
A. A representative of Romtec Utilities will be present the day the pump station is installed to provide
technical advice to the Contractor.
B. The Contractor shall be responsible for coordinating the required field services with Romtec Utilities.
2.6 Start-up/Testing and Owner Training
A. After installation, pump station start-up shall be performed by the installing contractor under the
supervision of Romtec Utilities’ start-up technician.
B. Start-up to include two (2) days of on-site field service.
