At the beginning of this project I was informed that a dedicated water meter was required for the fire sprinkler system and a separate dedicated water meter was required for the domestic demand for each townhome. After installing sprinkler systems in 3 buildings another townhome project came up in Addison and the developer and myself met with Chief Robbins and he said that he would consider going to 1 water meter per townhome if ithe calculations would work. Ashton Woods has asked me to see if it is possible to go to 1 - 1 1/2" water meter per townhome at Asbury Circle. Below are the calculations and information: Original flow test: 77 psi Static 62 psi Residual 40 psi Pitot 1061 gpm Flow The 2nd floor of the townhomes has the largest demand - remote area at 55.3 gpm at 65.04 psi at street 13R classified town homes with projected domestic demand: 56 gpm Fire Sprinkler Demand 25 gpm Domestic Demand 5 gpm Safety Factor 86 gpm Total Demand through water meter Plumber is currently installing Hersey Meters, Model - MVR 1 1/2" for fire sprinkler water meter Flow characteristics: Meter Size Typical Operating Range Maximum Continuous Maximum Intermittent 1 1/2" 2 to 100 gpm 70 gpm 110 gpm Please contact me to discuss the proposal to go to 1 - 1 1/2" water meter at Ashton Woods Townhome Subdivision - Asbury Circle for domestic and fire sprinkler demand.
