Dye Testing

Dye testing involves placing a non-staining water soluble dye tablet in the drain or downspout of your property and flushing it with water. The area is then examined for the appearance of traces of dyed water.

Property owners in Pittsburgh who wish to sell their property on or after July 5, 2006, must be in compliance with the Dye Testing Ordinance.   
 
After the test is done it will be determined whether or not the property is located in a combined sewer area or a sanitary sewer area. Upon the results of the property, the property owner must do the following:

  • If it is determined that the property is located in a combined sewer area, no dye test is required and the property owner will receive an Evidence of Compliance Certificate and will be able to move forward with the sale of property.
  • If it is determined that the property is located in a sanitary sewer area, a dye test must be performed and the results must be reported to the Pittsburgh Water and Sewer Authority

If a dye test is required and the property passes the dye test, no further work is necessary. The property owner will receive an Evidence of Compliance Certificate and will be able to move forward with the sale of the property.

If a dye test is required and the property fails the dye test, corrective actions must be taken. After the corrective actions have been made, a subsequent test is required. When the property passes the subsequent dye test, the property owner will receive an Evidence of Compliance Certificate and will be able to move forward with the sale of the property.
