Masonry Cleaning Wastewater
WEP issues permits to accept the wastewater from
masonry cleaning and restoration projects.
Contaminants from masonry cleaning and restoration can
be present in the masonry itself or from airborne
pollutants from vehicle exhaust. Common pollutants of
concern include lead, nickel, and zinc.
Masonry permits require proper collection and
treatment of wastewater. Contractors often install
plastic sheeting to collect and divert the wastewater
to a holding structure before treatment and discharge.
Treatment is typically accomplished by filtration. If
metals concentrations are unusually high, advanced
treatment using chemical precipitation or membrane
technologies may be required. Laboratory analyses are
required to determine the acceptability of the
wastewater for discharge to the sewer system.
