Lesson Overview
Large-scale cold water storage cisterns provide bulk water storage for commercial and multi-storey installations. Correct material selection, warning pipe arrangements, and interlinking methods prevent contamination, structural flooding, and water stagnation.
Learning Objectives
Identify the materials and British Standards used for one-piece and sectional storage cisterns.
Calculate the required dimensions and positions for warning pipes, overflows, and air gaps on cisterns over 1,000 litres.
Apply the correct installation and piping rules for connecting multiple cisterns in parallel and series to prevent water stagnation.
