Onsite Wastewater System for 400,000 SF Distribution Facility
Location
Boylston, MA
Client
Developer / Civil Engineering Firm
Project Type
Commercial wastewater design
Overview
Robial designed a 4,000 GPD onsite wastewater system for a new distribution facility on a 60-acre site with no sewer access. The final system included septic tanks, a pump station, and a remote pressure-dosed soil absorption system located 1/3 mile from the building.
Challenges
01
02
Extensive site testing (36 test pits over 4 months) to locate compliant soils
Complex site geometry with shallow bedrock and wetland constraints
03
04
Fast-moving construction schedule with multiple consultants and shifting site plans
Long-distance effluent conveyance with power and controls routed back to the building
Our Approach
01
Located and permitted a remote SAS through phased testing and BOH coordination
02
Designed a full Title 5-compliant system with long-distance force main and dosing controls
03
Coordinated closely with MEP, stormwater, and site/civil teams to align grading, utilities, and plan layers
04
Performed construction inspections and start-up calibration to ensure proper operation from day one
The system was approved and is operating as designed. Robial’s design coordination and on-site involvement helped avoid delays, resolve field changes, and deliver a reliable system under complex site conditions.
