I have a customer that has an existing "irrigation system". He is currently using impact rotors on pipe stands to water a nursery of small potted trees and he is getting water from a stream next to the property. This is more agriculture based than commercial or residential. The property is located next to a residential area and he needs to plant and water a new hedge row of 500 feet. I would suggest inline drip tubing on city water but the tap fees would be much much more than the system costs. Is it possible to use drip on stream water? He mentioned past problems with debris in the water so certainly filters would be required. Since city water is not an option, what would you recommend?
