The water source

In Consideration 5: Your water source, we looked at how your water source generally falls into two categories – surface water and groundwater. Within the first module, we also looked at the type of water, water availability (max discharge m3/h (gpm)), constraints, and water content (physical and chemical). As such, we will not cover this info here. What is important to note is that your water source, including water availability and water content, will have some impact on almost every component in your irrigation system, along with agronomic considerations. For example, if you source water from a well, and you have high sand content, you will most likely need a hydrocyclone filter.

 

Aeration

If you have dissolved minerals, such as iron and manganese, aeration is recommended. The aeration should occur before the reservoir. 

Settling ponds

The two functions of settling ponds are to:

  1.  Balance the water use required of the pump system.
  2.  Settle some of the debris in the water.

Points to remember:

  • Settling ponds need to be cleaned periodically (from the bottom).

  • The minimum size should be the daily water volume.

  • Normally, 24 hours are required for settling for common conditions. Longer is required if you have more severe conditions, smaller ponds, or if you are using flocculants.
