There are a lot of variables in what you are asking for. First what is the source of your water supply. Generally if you see a water holding tank, say a 1500-2000 gallon it is because there demand is much greater then there supply. There are alot of options but we need to know the source first. When you see large holding tanks often it is because the water supply is to low so by having a tank you can continue to store water while there is no demand. Often ther will be a float switch in the tank to shut of the water supply filling the tank at full capacity and a submersible high output pump in the tank for discharging water at a high volume say 25-40 gallons a minute. From the tank if you were to run 1 1/4 - 1 1/2" p.v.c around the perimeter of the track and mount hose spigots with a large inlet hole say 1" and good 3/4" hoses you should have a $hit load of water available. Hope I wrote this where it can be understood.
