The Briarcliff Manor Police Department and the volunteer Briarcliff Manor Fire Department are stationed at the Briarcliff Manor Village Hall.^[134][135] The Police Department has 19 personnel—a chief, lieutenant, five sergeants, and twelve patrol officers—and one part-time civilian.^[26] The Briarcliff Manor Fire Department Ambulance Corps provides emergency medical transport with two ambulances.^[136] The village is also serviced by two private EMS providers.^[26]

Consolidated Edison provides electric power and natural gas to the village, and the Briarcliff Manor Department of Public Works supplies water from the Catskill Aqueduct to the village's water system.^[28][137] The department also maintains the sewer system, village vehicles, roads and grounds, operates a recycling center and removes snow.^[138] In 2012 the village tied for fourth place (out of 48 Westchester municipalities) in the percentage of recycled waste (71 percent, above the county average of 52 percent).^[139] The department, primarily rooted in the 1941 sale of Walter Law's Briarcliff Table Water Company, began with a state-mandated street commissioner. The commissioner in 1914 was Arthur Brown; asked by village officials if he needed an automobile, Brown replied that he preferred a horse but would use an automobile if the village purchased it (it did not). The department has about thirty vehicles and employs twenty-nine people.^{[3](p87)[140]}

The department operates the Long Hill Road water treatment plant and village pump stations. The Long Hill Road pump house is the primary water supply for the village with supply capacity exceeding 3.5 million gallons per day (MGD). Briarcliff Manor's average daily water supply demand is 1.45 MGD with a peak demand of 3.5 MGD. Briarcliff Manor has four water storage tanks (at Rosecliff, Farm Road, the former King's College and the Edith May Conference Center) and two pump stations (the Long Hill Road pump house and the Dalmeny Road pump station).^[28]
