SUBJECT:  Sanitary Sewer Pump Stations Upgrade at Seattle-Tacoma International Airport
(CIP #C102032) 
Amount of This Request:  $1,133,000   Source of Funds: Airport Development Fund 
Est. State and Local Taxes: $69,000     Est. Jobs Created: 7 
Est. Total Project Cost:    $1,133,000 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to complete the design,
advertise for, and proceed with construction of the Sanitary Sewer Pump Station Upgrade project
at the Seattle-Tacoma International Airport (Airport). This request seeks a single authorization
to perform the design and construct the sewer upgrades to complete the work quickly and take
advantage of an existing, competitively bid, indefinite delivery, indefinite quantity contract. The
amount of this request is $1,133,000 and the total projected cost is $1,133,000.
SYNOPSIS: 
Commission authorization is requested to design, advertise and execute construction contract for
Sanitary Sewer Pump Station Upgrade. This project is included in the 2013-2017 capital budget
and plan of finance. 
The sanitary sewer pump stations have not been upgraded with current technology to properly 
control and monitor the whole system. This project will enhance the operation of approximately
twenty-two sanitary sewer pump stations at the main terminal and elsewhere at the Airport.
Many of these pump stations have operated without backup pumping and control capabilities that
are essential to assure risk free operation and maintenance. This project will upgrade all twentytwo
pump stations with reliable controls via the facility monitoring system. 
This authorization requests both design and construction in one request, rather than separately
seeking design first and returning soon thereafter for advertisement and construction as a second
request. Design will take less than two months' time by using in-house technical staff and
outside consultants that are already available via an existing Indefinite Delivery/Indefinite

Quantity (IDIQ) contract that was competitively procured earlier. In addition to streamlining the
request process for this item, the minor risk of a sewage overflow may be mitigated by
expediting this action in a single step.
The design package will be prepared in-house with support from outside consultants (as needed)
using the Mechanical-Electrical IDIQ Service Agreement, which has an ordering period end date
of April 26, 2014. 
The control and monitoring hardware components and software portion of this upgrade project
are a Siemens proprietary system. There is an existing Competition Waiver in place that covers
the Siemens system hardware, software, and system graphics. The project specifications will
include the proprietary system and the equipment will be included in the bid package. The
construction contract will include acquisition and installation of control system proprietary
hardware, software, and system graphics as well as the non-proprietary system elements such as
conduit and wiring. 
BACKGROUND: 
The sanitary sewer system in the terminal areas around the Airport is equipped with pump
stations to pump wastewater into the sanitary sewer. Each of these pump stations has one or
more deficiencies. Several pump station failures have occurred in the last five years, resulting in
sewage overflows and associated potential health and safety concerns. Eleven of the lift stations
do not have modern ultrasonic level transmitters needed to control the pumping operations. 
Other miscellaneous control upgrades are needed on other pump stations to better control and
monitor system performance from the Central Mechanical Plant via the facility control and
monitoring system to allow timely response to a malfunction. 
A good faith survey for regulated materials is a typical required action and will be completed by
an outside consultant and managed by Port Construction Services (PCS). Removal of regulated
materials, if required, will be completed by the construction contractor. 
PROJECT JUSTIFICATION: 
This request will upgrade the existing Sanitary Sewer Pump Stations with an up to date system
that will monitor and control the operation of the pumps; monitor the levels in the sumps; and
monitor and transmit system alarms to the Central Mechanical Plant. 
Project Objectives: 
The upgraded system will decrease the response time to problems for Aviation
Maintenance personnel 
Lower the risk of undetected sewage overflows 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
The Scope of Work includes the following elements: 
Perform field investigation to confirm conditions and prepare design. 
Provide good faith regulated materials survey  design for asbestos removal.

CPE Impact              Less than $.01, but no change from business plan
forecast as this project was included. 
Lifecycle Cost and Savings: 
The impact to ongoing operational costs is negligible. The costs to operate and install the
controls and monitoring system will be offset by the savings in periodic manual monitoring of
the pump stations. In addition the costs of responding to undetected failures will be minimized. 
STRATEGIC OBJECTIVES: 
This project will support our Century Agenda Strategic Objective to meet the region's air
transportation needs at the Airport for the next 25 years by ensuring that the infrastructure is
reliable and well controlled. 
ENVIRONMENTAL SUSTAINABILITY: 
This project demonstrates environmental sustainability by improving Port assets and better
utilizing existing resources. The project will replace existing equipment with new more efficient
systems. Existing materials and system components will be recycled where possible. 
BUSINESS PLAN OBJECTIVES: 
The project will provide a stable, reliable infrastructure that supports the Aviation Division's
strategic goal of operating a world-class international Airport by anticipating and meeting the
needs of our tenants, passengers, and the region's economy. 
TRIPLE BOTTOM LINE SUMMARY: 
This project supports: 
The economy by minimizing Aviation Maintenance response time. 
The environment by minimizing the risk of operationally disruptive sewerage overflows
and by recycling a portion of the materials to be removed and by installing new more
efficient control and monitoring system equipment. 
The community by keeping the Airport operating as efficiently as possible and by
minimizing health risks to workers that could be associated with sewage overflows.

ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1  Leave the pump station controls as is and live with the lack of alarms when
pumps fail or the sewage wet wells overflow. This alternative represents a continuing risk to the
Airport. This is not the recommended Alternative. 
Alternative 2 - Systematically upgrade the most pressing deficiencies of each sewage pump
station. This is the recommended alternative.
