Precast Concrete Interceptor Vault Top and Section Views

About this detail

An underground precast concrete interceptor vault features dual compartments with 24-inch gastight cast-iron frames and gasketed covers, supported by grade rings of 3-inch, 6-inch, and 12-inch sizes as required. Internal plumbing consists of 4-inch standard pipe and fittings with inlet and outlet connections, plus a 2-inch vent extending above. The top view details the overall dimensions of 9'-6" by 5'-9" alongside lifting loops for handling the heavy precast structure. The side section indicates internal liquid levels referenced to an approximate design groundwater table, maintaining a minimum 14-inch clearance above grade rings.
