The East Bay Regional Park District (EBRPD) is designated a special district by the state of California. It is the largest special district in the United States, with over 90 percent of its land protected and operated as natural parklands.
With an annual budget of $140 million and nearly 700 employees, the District is so big that it has its own police department with 62 police officers. There are also ten fire stations and a full-time, on-site helicopter unit. For such a large and widely spread District, effective management of water and waste water is critical. The supply of potable water, and waste water collection and treatment, needs constant monitoring and control across all facilities to prevent problems and avoid any possible environmental issues.
