Street Drainage and Detention Systems
This workshop is a more advanced and detailed follow-up to the Introduction to DRAINS workshop. It covers all the capabilities of DRAINS relating to piped urban drainage systems, considering analysis as well as design.
Procedures for design of street drainage and inter-allotment drainage are outlined, and issues such as pit inlet capacities and pressure changes are explored in depth. Small detention storages such as those used for on-site detention are explored in greater depth than in the introductory workshop.
The workshop is suitable for civil engineers and related-professionals who have completed the Introduction to DRAINS workshop, or who have working experience of DRAINS. It is presented by Geoffrey O’Loughlin and Benjamin Kus, and runs from 9 am until 5 pm, with 6.5 hours of tuition. The topics covered include:
- An overview of design procedures for piped drainage systems, and the role of analysis,
- Comparing the ARR 2016 procedures with earlier methods,
- Review of a DRAINS pipe system model for design of a street and inter-allotment drainage system,
- Optimisation of the initial designs produced by DRAINS,
- Connections between DRAINS and other design programs, with an example using Advanced Road Design,
- Complex aspects of piped drainage systems, including connecting new pipelines to existing systems, loops and effects of reverse flows,
- Additional features of the premium hydraulic model,
- Detention basin calculations, analysis of detention and retention systems in DRAINS,
- Review of examples of detention system models, and exercises in building models that combine piped drainage with a detention basin,
- Construction and costing issues, and
- A review of problems that may be encountered in pipe and detention basin systems.
Those attending the workshop will be provided with:
- an understanding of design requirements and processes for street and inter-allotment piped drainage systems,
- the ability to set up and interpret DRAINS models of complex piped drainage systems, and
- understanding of detention basin calculations, and application of these in DRAINS.
