Stormwater Fee

Centre and Herron Stormwater Improvement Project Centre and Herron Stormwater Project in the Upper Hill District

A stormwater fee for Pittsburgh is a notable change. Historically, we have funded our stormwater services from wastewater rates based on water usage. The stormwater fee is based on a property's hard or impervious surfaces. All property owners in Pittsburgh contribute a share proportional to the amount of runoff generated by their property. 

Establishing a fee based on hard surfaces such as roofs, pavement, and asphalt is a more equitable way to charge for stormwater and fund the stormwater projects and initiatives needed to improve stormwater management in Pittsburgh.  

As part of implementing the stormwater fee, wastewater conveyance rates have decreased since the stormwater fee begins to recover the previously included stormwater costs.

Our sewer system was not built to handle increasing amounts of rain due to climate change, and with much of the city paved over, there is nowhere for the water to go. With new stormwater projects under construction and a stormwater strategic plan underway, we are making continuous strides to improve stormwater management in Pittsburgh. However, we cannot continue this work without making certain that our rates reflect the need to pay for the construction of stormwater infrastructure.

Stormwater Credit Program

When it comes to managing stormwater, there are things we all can do to help! 

Our Stormwater Credit Program offers a discount on the monthly stormwater fee. Property owners choosing to manage stormwater on site may reduce their monthly stormwater charge. Installing stormwater management systems such as a rain garden or an underground stormwater system on private property are examples of how a private property owner may earn a credit.
