Suffolk, MA: Boston combined-sewer dewatering approvals

BWSC identifies drainage/dewatering discharges requiring its permit and states that collected water discharged to a combined sewer, directly or through a storm drain leading to it, requires an MWRA Sewer Use Permit. This is a Boston service-area reference.

Remote plan-based takeoff support; no local office, completed local project or site investigation is represented by this page. Cost, delivery schedule and deliverables depend on the agreed project scope.

What this changes in the bid review

Estimating interpretation: The nearest inlet does not establish an unrestricted discharge point. Build the temporary conveyance and treatment scope around the approved route, and state the excavation-duration assumption separately.

Check the project documents

Mark each item after reviewing its supporting document.Trace the proposed discharge to the actual receiving system.List BWSC and applicable MWRA approvals as separate inputs.Obtain permitted water-quality, treatment and monitoring conditions before defining temporary work.

Clarification to request: Does the proposed dewatering route reach a combined sewer and what BWSC/MWRA conditions apply?
