Pretreatment Facilities for High‑Strength Liquid Waste
BlueGate Infrastructure develops and operates private pretreatment facilities for hauled grease trap waste.
BlueGate is a private-capital–backed infrastructure platform focused on the off-site receiving and pretreatment of grease trap waste in U.S. metropolitan areas.
BlueGate facilities condition high-strength waste upstream of municipal sewer systems and discharge only pretreated effluent under permit. This approach complements local wastewater infrastructure and helps reduce FOG-related system impacts.
System Context
An Infrastructure Gap in Grease Trap Waste Management
Fats, oils, and grease (FOG) are a persistent operational challenge for municipal sewer systems and Wastewater Treatment Plants (WWTPs).
Grease trap waste is a leading contributor to blockages, sanitary sewer overflows, and pump station failures, particularly in dense urban areas where food service activity has increased.
At the same time, enforcement of grease trap ordinances has increased collection volumes. Many POTWs, however, were not designed to receive high-strength hauled waste and face capacity, odor, and operational constraints.
Limited receiving infrastructure forces haulers to travel long distances or concentrate loads at a small number of facilities.
Stand-Alone Receiving and Pretreatment, Upstream of the Sewer System
Facilities use engineered, purpose-built pretreatment systems and are located strategically near major waste-generation nodes, while remaining aligned with municipal capacity and permitting requirements.
BlueGate facilities are designed to support existing municipal pretreatment programs and sewer use ordinances.

Positioning
A Defined Role Between Haulers and Wastewater Treatment
BlueGate is independently positioned between grease generators and municipal wastewater systems, allowing WWTPs to retain control over discharge conditions while reducing exposure to high-strength, variable loads.

System Effects
Upstream Pretreatment that Relieves System Stress
There are multiple operational benefits for both haulers and municipal wastewater systems, primarily by improving receiving efficiency, reducing system strain, and physical-chemical pretreatment to remove grease, solids and BOD prior to permitted sewer discharge. Where appropriate, recovered brown grease is removed from the wastewater system and sold offsite as a biofuel feedstock.

Regulatory Framework
Permitted Operations with Municipal Oversight
BlueGate facilities operate under applicable local and state permits. Municipal oversight is maintained through permit conditions and reporting requirements.
Only pretreated effluent is discharged to the municipal sewer
Discharge occurs through permitted connections and sampling manholes
Effluent meets applicable local pretreatment standards
Operations are designed to avoid shock loading and uncontrolled discharges
Monitoring, sampling, and reporting are conducted as required by permit
