Design Investigation – Geothermal Well System

Client: Boston Architectural College (BAC)
Sector: Institutional
Location: Boston, MA
Service: Sustainable Development

The Challenge:

BAC-geothermalBoston Architectural College (BAC) underwent a $14M renovation project that included the city’s first Green Alley, a model for urban centers to revitalize blighted alleys into eco- and people-friendly spaces.  The project included a fatal flaws analysis for bleed water discharge from the system.

The Environmental Services Provided:

SAK Environmental assisted in the design and permitting of BAC’s geothermal heating and cooling system the consisted of eight, 1,500 foot deep standing column wells and one injection well.  SAK reviewed the well construction logs, the geotechnical information, and the design of the subsurface stormwater infiltration gallery.  SAK conducted field testing and computer simulation of groundwater mounding from the alley’s new recharge basin that returns stormwater to the ground that was previously discharged off-site through the city’s stormwater drainage system.  SAK’s fatal-flaw analysis included evaluating discharge options for the systems bleed water, which determined if a physical or regulatory condition to the project is a “game-stopper” to further consideration of a particular discharge alternative.

Summary of Services

  • Sustainable Development
  • Design review
  • Hydrologic analysis
  • Permit review
  • Wastewater Discharge Analysis

The Result:

SAK helped support the BAC’s sustainable initiatives and the city’s first Green Alley become an active part of the BAC’s campus neighborhood, supporting groundwater recharge and energy efficiency on this important project.
