Parking Garage Drainage: A Bethlehem Guide

2026-01-09

Plumbing Guide

A parking garage collects water from cars, weather, and washing, and it all has to drain somewhere. The drainage system must handle oil, grit, and storm surges without backing up or polluting.

Parking Garage Drainage: A Bethlehem Guide

The drains

Floor drains and trench drains carry water off each level, pitched toward the collection points so puddles do not form.

The oil separator

Because cars drip oil and fluids, garage drains often run through an oil-water separator before the water leaves the property.

The pumps

Below-grade levels need sump pumps to lift the water up to the storm or sanitary system.

The grit

Sand and road salt wash off the cars and settle in the system. In Bethlehem, winter salt can corrode the lines, so material choices matter.

The separator

The oil-water separator needs periodic pumping and inspection, and the record matters for environmental compliance. A full separator sends oil downstream.
