Irrigation Design Management - Agricultural Irrigation Manual

Hello, my name is Carlos Pacheco C.I.D Res./Com./Ag. and I have been an irrigation designer since 1997. I have designed and managed many different projects everything from the small back yard hobby farm to large 50 to 100 acre new vineyard installations.

Having designed, installed, and repaired irrigation systems with many different water requirements and application methods. I've had the opportunity to run into many clients who wanted to learn how the system worked, so they could do their own repairs or even build a system of their own.

I then decided to put together this manual to help the average farmer or for that matter anyone to design, install and manage their own system with the confidents of years of experience that they are able to reference in this manual. Not to mention cutting out the costs and difficulty with dealing with contractors.
