Drainage Standard Details Drawing with Trench Drain and Soakaway

 This AutoCAD DWG file presents comprehensive drainage standard details used for building services and infrastructure planning. The drawing includes multiple enlarged construction details such as a typical trench drain with grating cover, floor drain details with P-trap, floor clean-out connection, pressure break manhole, and ramp trench drain arrangement. Detailed sections illustrate sleeve holes through foundation walls with a link seal, pipe bends in stacks, rodding eye access, velocity breaker, sewer gas intercepting trap, FCU and AHU condensate drain connection, and sand trap construction. A complete linear soakaway plan and section are shown with perforated PVC pipes, pea gravel layers of 150 millimetres thickness, geotextile membrane wrapping, and overall soakaway lengths up to 32000 millimetres. Pipe diameters such as 100 millimetres, 150 millimetres, and 160 millimetres are clearly indicated along with slopes like 1 in 120 and minimum cover requirements. All dimensions are in millimetres, and the drawing is suitable for architects, civil engineers, MEP consultants, and builders working on drainage execution using AutoCAD DWG files, complemented by structural and civil reference drawings, such as pump house section and reinforcement layout prepared in AutoCAD DWG format for coordinated construction planning.
