About this workshop
This workshop covers the preparation required for developing a drainage design for a nursery site. It investigates the features that can be incorporated into a drainage system design, including associated hydraulics.
Among the skills participants will gain from this workshop is the ability to identify whether to recycle, reuse or dispose of drainage water that comes from irrigation and stormwater. Participants will be able to assess a site for drainage, develop a drainage design and identify the most appropriate options for dealing with drainage water.
Participants who complete the workshop will also benefit from discussion about how water quality impacts upon, and is influenced by, the different reuse options.
Workshop outcomes
At the completion of the workshop participants will be able to:
- Assess a site for drainage
- Develop and apply a checklist to assist in planning for drainage
- Develop an action plan or task list for designing drainage for the site
- Describe the hydraulics associated with drainage system
- Determine the options to incorporate into a drainage design
- Describe the options for dealing with drainage water
- Calculate drainage volumes
- Determine the impact of water quality on reuse options
- Describe the options to maintain water quality
- Determine the regulatory factors that influence water drainage options
