Primary/secondary filtration

Almost all irrigation systems will require both primary and secondary filtration.

Primary filtration
Located in the pump shed.
Provides filtration for the overall system before the water goes to the mainline.
As the name suggests – it is the primary filtration for the system.
Usually large, automated media, screen or disc filters, combined sometimes with a hydrocyclone filter.
Secondary filtration
Located in the field – one per block.
Also called a backup filter.
As the name suggests, it provides a backup in case particles pass the primary filtration, or if there is damage in the mainline.
Usually small plastic manual or semi-automatic disc or screen filters (2” – 4”)
