AV-PMG

Introduction
Purpose: Designed to receive and process
wastewater/sewage from aircraft lavatories
Process: Collected from aircraft using
specialized carts (biffy trucks) then
transported to the Biffy Facility
Discharge: From the Biffy Facility into the
airport's sanitary sewer system.
This is the only facility at SEA managing waste
from aircraft operations.

Project Location

Biffy Facility is located east of North Satellite adjacent to Air Cargo Road
3

Project Scope
• Extend useful life of Biffy Facility
• Improve infrastructure, reliability,
and operations
• Bring facility up to fire codes,
standards, FDA & NFPA guidelines
• Provide redundant pump system
and vacuum tank
• Space heating for freeze protection,
ventilation

4

Project Justification
• Porous wooden frame enclosure, does not meet NFPA guidelines
• Inadequate freeze protection, lacks ventilation
• Single pump system and vacuum tanks - End of life and prone to failure.
• Multiple overflow/backflow incidents reported due to failures

Mitigation Plan

Lead Time to Delivery:
VFDs, pumps, vacuum tank lead times are
expected to be 6-12 weeks

Track delivery times and request contractor to get
long lead time equipment submittals approved
first.

Facility Assembled Structure (FAS) Permit
may be required if a prefabricated
structure is proposed for the facility

Coordinate with design team to identify the
applicable permit and inspection requirements
and note them on the plans for the contractor.

Equipment cost escalation due to tariffs

Track equipment costs thru design cost estimates
to understand tariff impacts with certainty.
Evaluate sourcing domestic equipment locally.
