Highland Reservoir Project

The City of Rochester is embarking on a study to investigate options for addressing the United States Environmental Protection Agency’s (EPA) Long Term 2 Enhanced Surface Water Treatment Rule (LT2) and improving other unique water quality and operational challenges associated with Highland Reservoir.

Project Background

The City of Rochester, through the Department of Environmental Services / Water Bureau, maintains three finished water reservoirs, two of which are open. Highland Reservoir is the City of Rochester’s smallest uncovered finished water reservoir; having a capacity of approximately 26 million gallons.

In 2006, the EPA adopted a regulation known as LT2. LT2 compliance requires public water systems to either cover their uncovered finished water reservoirs or provide treatment to protect against microbial contaminants, such as Cryptosporidium and Giardia.

In 2006 the City conducted a study to identify various alternatives for compliance with LT2. In 2009 the City entered into a Bilateral Compliance Agreement (BCA) with New York State Department of Health (NYSDOH) and the Monroe County Department of Public Health (MCDPH) for compliance withLT2. The BCA obligates the City of Rochester to bring all three uncovered finished water reservoirs into compliance with the LT2 rule by 2023. As a result of LT2 and the BCA, the City of Rochester installed a synthetic liner and floating cover on Rush Reservoir in 2012. 

This new study intends to further evaluate the available compliance alternatives to Highland Reservoir and engage the public to ensure the stakeholders are well-informed about alternatives.
