Located on the grounds of the Marathon Detroit Refinery, a new Waste Water and Storm Water Treatment Plant was constructed.  Construction of this plant was done within the refinery battery limits and without any interruption to the owners daily business operations.

Hatzel & Buehler was responsible for the various electrical installations, heat trace and instrumentation.  The Foundation Field Buss controls for this installation were new to the refinery and were incorporated into the owners DCS system.
