It will mostly depend on your city water supplier. Big Water takes a separate tap and a larger meter. Some of that expense may come back if the separate meter allows for paying lower sewerage (sometimes, sewerage fees come as a multiple of the meter reading)Thanks. About how much more (A guesstamate in percentage) did it cost over a "run of the mill" system?I've done systems like that, with mammoth overkill capabilities, and in my opinion, they are more praiseworthy in concept than in reality.
Grey said... "In short you want to find out your static pressure (at the outside bib for example), your flow rate, sizes of your water supply line, water meter. After some calculations you would get a value of dynamic pressure available for sprinklers. That pressure would determine maximum spacing of your sprinkler heads and what type of sprinklers to use, i.e. spray heads or rotors covering areas."
Yeah, done that, got very miserable results for what I "want" because my static pressure at the hose bib is regulated by the pressure valve supplying the whole house. That pressure has to remain below 50 psi or else I get water hammer at the farthest faucet (poor plumbing design by the builder ). One would think that 50psi is a good starting point but I only get 5.5 gpm (avg of three 5-gallon bucket tests) from the hose-bib closest to the water meter.
I have just finished the yard measurements and the next step will be to have a separate meter installed (largest supply line diameter that the city will allow for residential -- don't know, will find out). Then I can do the measurements using as much pressure as the city will give and as much gpm that the meter will pass.
I am stuck on building a system with the least amount of zones as possible... I am a stubborn man.
