Frequently Asked Excavating Questions

How long will my sub-irrigation/drainage system last?

The longevity of a sub-irrigation/drainage system depends on several factors. The most important aspect to maintaining a long-lasting system is accurate grade control while installing the tile. Incorrect installation will allow the pipe to silt in with sediment and stop the flow of water, essentially ending the life of that particular tile line. Tree roots are another concern. If trees are left too close to the tile, they will grow into the pipe, stopping the flow of water. The maintenance of the outlet is an area of concern, so it is important to have an animal guard and, if needed, a flap gate installed to prevent entry of animals and debris through the outlet. With proper installation and maintenance, a lifespan of up to a 100 years can be expected.

How much water do I need to effectively irrigate with sub-irrigation?

Approximately a third to half the volume is needed versus pivot irrigation. We recommend a pump that can provide 3-4 gallons per minute per acre.
