    I need to have a 10,000 gallon cistern installed for an irrigation system. Water will be delivered via tractor trailer. I want to use a submersible pump but I have never installed one in a tank. Can I lay it on its side in the bottom of the tank? I have heard of flow inducing sleeves, does that apply here? If so could anyone explain this ? I have only ever installed pumps in well casings. Thanks

    Yes you can lay it on its side. The shroud is needed to cool the motor, and makes a good place to lay the pump on. You can use a couple extra pieces of 4", 100# sewer pipe after making the shroud to use as a cradle to lay the pump on the bottom of the tank.

    Thanks that is exactly what I am looking for. Was thinking of wiring a simple float switch to shut down the pump in a low water situation. Any recommendations on a switch?

    Just use a Cycle Sensor to cut the pump off if the tank runs dry. Then you don't have any float switch to mount.

    Thanks again. We are getting salt water intrusion as the house is right on a bluff overlooking the bay. The cistern, pump system, alterations to irrigation system is going to cost every bit of $50,000. Not to mention the weekly water deliveries at $600 a piece.

    If I was you, I believe I would invest in drought tolerant landscaping.

    Trickle down economics at its best..

    I like using a 4" abs seal & 4" sch 4PVC for a flow inducer sleeve. Works great/looks & sounds expensive.

    Do you remove the check valve and install one vertically on the drop pipe?

    You can leave the original & put one vertically

    I work with some resorts in Cancun that have salt water intrusion like that. The driller figured out how to cement off the upper section of the well and greatly reduced the salt intrusion, which now works fine for irrigation. Everything else goes through the largest RO system I have even seen. Then we have booster pumps with CSV's to supply the RO water to the resort, just like supplying a little city.
