HI guys.
I am building new (2800 sf home, 2.5 baths) and installing a new well pump. I also have SOME irrigation set up now - only about a acre of dripline. I figure I will irrigate in the evening on a timer. Here is the issue: my state requires fire sprinklers. The sprinkler code requires 260 gallons of water in 10 minutes time (or 26 GPM).
Well specs: 20 GPM well, 202 feet deep, well report says water level is 30 feet.
I am trying to get a straight answer on a good system design.
First, I want to pick the right pump and tank. I would think that I should get a 20 GPM pump - so that I never draw down the water level. That said, what depth should the pump be set at and what HP do I need?
Next, what size tank? And Why?
Next, I would like a CSV. Is this appropriate for me? Where does it go in the whole system?
Finally, I need to make sure this will all work for the sprinkler system design - this all has to get past the code guys. (I want to get the pump NOW and get irrigating while the house build is going on). My hope is that I can rely on (1) the existing tank supply and (2) the 20 GPM incoming water to meet the 26 GPM requirement. In other words, I THINK that I need to have enough tank supply that the 6 GPM that I am losing does not tap me out within the 10 minute requirement. That, to me, means that I would need 60 gallons minimum available in the tank.
Can anyone confirm this thought process - ESPECIALLY with respect to the fire sprinkler.
THANKS
