The Sewer Services Division of Oakland Public Works is responsible for performing preventive maintenance to over 920 miles of sewer main, ranging from six inches to over 66 inches in diameter. Preventive maintenance consists of closed circuit television (CCTV) inspections, cleaning and performance of minor repairs. Larger repairs are given to the Bureau of Design and Construction for completion. Sewer Services staff also make recommendations to City engineers for complete pipe rehabilitation projects.
The wastewater collection system (sewers) in Oakland conveys wastewater from homes and businesses to the East Bay Municipal Utilities District (EBMUD) treatment plant. Oakland property owners are responsible for the private sewer laterals that connect their homes to the sewer system, including the lower lateral.
The Sewer Services Division has an array of equipment that is used for sewer maintenance, including CCTV units, power-rodding trucks and hydro-flusher trucks. This equipment visually inspects sewer pipes, cleans pipes and clears blockages. Blockages are caused by debris; fats, oils and grease; and tree roots that gather in sewer pipes.
