IRRIGATION: IRRIGATION WATER SOURCES

There are several possible water sources for a home irrigation system. Water can be taken from a city water supply, private well or from an open water source such as a lake or pond. If a city water supply is used or a well with a pump already exists, the system should be designed for the flow rate and pressure available from the existing water source.

If a well is to be drilled and a new pump is to be purchased for the system, the well and pump must be sized in the design process. For a surface water supply the pump must be also sized during the design process.

In Florida, well and pump permits from the local water management district are required in some cases. The local water management district should be contacted for specific information on permitting. In addition, some municipalities require permits and have restrictions on some wells.
The water supply must provide the volume of water necessary to meet the irrigation requirements of the plants within each zone and within the maximum time allotted for irrigation of that zone.

The flow rate of water available from the water source, the water application rate, and the time required for irrigation will determine the number of irrigation zones and the size of each zone.
