About the Water Quality Protection Charge

The Water Quality Protection Charge (WQPC) is a part of Montgomery County property tax bills. The WQPC raises funds to improve the water quality of our streams and reduce the impacts of stormwater runoff.

Who Pays the WQPC?

All property owners in Montgomery County pay the WQPC, including businesses, HOAs and non-profit organizations.

The WQPC is calculated based on the potential for a property to contribute to stormwater runoff. Typically, a larger, more developed property produces more runoff, and therefore, receives a higher charge.

The Importance of the WQPC

Stormwater is rain that runs off hard surfaces and carries pollution to our streams. It is one of the biggest water quality problems in Montgomery County.

When left unmanaged, stormwater flows through storm drains to nearby creeks and streams at high speeds and in large volumes. This polluted, unhealthy water damages property, erodes creek banks, harms wildlife, and eventually ends up in the Chesapeake Bay.

Restoration projects funded by the WQPC reverse and prevent the impact of stormwater. They also create jobs and boost the local economy.

Your WQPC Helps Clean Our Waters

The WQPC funds many of the County’s clean water initiatives including but not limited to: restoring polluted and eroded streams, stream monitoring, storm drain cleaning and maintenance, inspection of stormwater management practices, and  protecting water quality and wildlife habitat.
