My residential irrigation system is currently connected to city provided water. In Georgia, we are in the midst of a total outdoor watering ban (from city provided water sources) and I am lucky enough to have a 2 foot deep creek at the back of my property. I own to the middle of the creek bed and current Georgia law allows me to draw water from creek. With all of this said, I am looking at the feasibility of installing a pump that will supply my irrigation system only (house will remain connected to city water). I was hoping that some of you pump experts could help me select a pump... Here are the specifics: My irrigation system has four zones (3 rotor zones @ 15 gpm and 1 drip zone @ 4 gpm) run on 1" main line (1" valves) and 1" laterals. All four zone valves are in the same location set-up as a manifold. From the point where water would be drawn from the creek to the manifold set-up, there is a distance of 200' linear and 30' of elevation change (the manifold is 30' higher than the creek bed). There is a 10' lift from the creek bed to where I would like to put the pump and then a 20' elevation change on the discharge side of the pump. I would like the pump to be 50' linear away from the creek bed, which would leave 150' linear on the discharge side to the valve manifold. I would like to have about 50-55 psi at the valve manifold in order to get good pressure to the rotors. I was looking at the 1.5 hp Goulds jet pump, but I am not sure if it will work or not. Questions: (1) Is there a pump that will meet my needs? (2) I have read a lot about pump cycling and with a range of 4gpm to 15gpm usage, is this going to be a problem? (3) Will I need to install a pressure tank as well? Thank you in advance for your help. If you need more specific information, I can provide.
