It outlines that the county has aging infrastructure in need of improvements, including 3 water treatment plants, 100 wells, nearly 8,000 miles of pipes, and 3 wastewater treatment plants. A 2012 report identified $1.1 billion in critical projects needed. Regulatory requirements from the EPA and state legislation adding further needs. The county's capital plan for FY 2013-2019 outlines $12.6 billion for water and wastewater projects to address deficiencies and meet regulatory mandates.
