SYNOPSIS

Urban drainage and stormwater system design in low-lying and tidal areas involves a number of special considerations.  Because of the difficulties of designing gravity systems in low-lying areas it may be necessary to use drainage gates/ tidal gates, and/or pumped systems. In some locations, there may be advantages in combining a tidal gate or drainage gate outlet with a pumped discharge.  This would allow water to drain by gravity when the tailwater level is low, saving on pumping costs, and to be pumped when the tailwater level is high.  A combined outlet system will be most practical where there is a large range in tailwater levels, typically 2.0 metres or more.  A detailed analysis of the storage and pump requirements will require data on the stage hydrograph of the tailwater, whether it be a river flood or tide cycle, and the calculation should be performed by computer methods.

This short course is intended primarily for drainage designers and others interested in the hydraulic design of stormwater pump stations to provide some basic design requirements and considerations as well as to introduce the design procedure in approaching the problems with hands-on case study in accordance to MSMA2.

Hands-on training using spread-sheet and public domain software will be conducted and all the participants are encouraged to bring along notebook computer for the exercise.

Who should attend:
• Those who are new in pumping drainage for urban stormwater runoff.
• Engineers, foundation professionals who desire to have a basic understanding of stormwater pumping drainage for urban area.
• Those keen to understand the use and application of computational model SWMM.
