The dye testing procedure works by inserting a powdered dye down a downspout or drain. This causes the water in that pipe to become fluorescent green and enables an inspector to identify where the pipe is emitting its water by checking downstream manholes. The inspector makes note of violations which are then reported back to both the Borough and the property owner.
Before selling property within the Borough a dye test must be performed by a plumber registered and licensed with the Allegheny Department of Health.
A dye test form must be turned into the Borough at least 14 days before the date of sale. If there are no illegal storm or surface water connections found on the property an evidence of compliance will be issued upon payment of a $35 fee. If the dye test reveals the existence of an illegal storm or surface water connection, no evidence of compliance will be issued until the illegal connections are removed and certification of such removal by a registered and licensed plumber is received. A compliant dye test is good for up to two years.
