What You Will Do

  • Contact your regional or local water authority.
  • Ask them for information on their water restriction policy.
  • When are water restrictions enforced and how do they affect water users?
  • Focus mainly on the problems experienced by agricultural users.
  • Consider ways that users can minimise their dependence on water access?
  • Write a brief report on your findings and submit with your assignment.
  • Visit a property that uses irrigation.
  • Discuss with the manager the methods that are used to decide when to water and how much ater to use.
  • Is irrigation an important element in the success or otherwise of the property?
  • Choose a drainage system to which you can get access.
  • Remember a drainage system is designed to cope with most situations.
  • They are many examples in your local everyday environment.
  • Some examples might include the guttering on your house or even on your car.
  • Discuss how the system operates and include sketches to show design features.
  • Contact a number of companies that offer computerised and technology solutions to irrigation.
  • Obtain prices and information if possible on appropriate working installations of their product.
  • If possible try a follow up visit at least one (1) operation and discuss the product with a user as well as a retailer. If distance or transport is a problem then you could try writing for this information, which would be suitable for the purpose of this set task.
  • Visit a property that uses large irrigation systems.
  • Enquire about the maintenance of their systems.
  • Consider how is water quality monitored and maintained?
  • Investigate at least two irrigation supply companies.
    • Observe how they service customers.
