First of all I would like to thank every one on this site for all the great info. Just reading the posts i have learned a lot and respect every one's opinion. Here's the situation - Long time Commercial Account came to me and wanted me to water. They did not want to put in irrigation because every peice of lawn is surrounded by asphalt. He said he didn't care about price if we would just water it. I bought a 16' trailer (from another LCO) that I setup with 2-325 gallon tanks on it, a 3.5 hp briggs/teel that will pump 5000 gph, and 3 25' sections of fire hose and a nozzle to fill/water with. Total, I have about $2300 in trailer, pump etc. I fill from a hotbox (basically a fire hydrant) that is like a mile away. This lawn takes 3900 gallons to water. I can fill, haul and unload 650 gallons in about a half hour. I pay $.002 per gallon for water (748 gal. = $1.50) If we charge $.15 per gallon you would be making $195 per hour. Sound like a fair price? Any advice would be great!
