Further details on product use and design for different applications can be found in Humes’ Concrete pipe reference manual (see www.humes.com.au). Our reinforced concrete pipes benefit from a range of sustainability initiatives, including the use of captured and reclaimed water at our concrete batching plants, a data-driven approach to water

Use our excel formulas in the downloadable spreadsheet templates to make storm sewer design calculations in S.I or U.S. units. The overall procedure for design of the storm water drainage system is discussed, along with the design criteria used for the storm sewer section between adjacent manholes. The rational method is used to calculate the design storm water runoff flow rate.
