I'm not sure what area of the country you are in but if it's hilly or mountainous region chances are they could've provided you with flow data from a hydrant located downhill of the actual job site (which could've been the nearest hydrant). For the life of me, I cannot find any 'bucket test' requirement in 13d or R am I going blind or is it a local requirement? -B- On 4/8/08, Ron Greenman <[EMAIL PROTECTED]> wrote: > > Reed, > > No problem.
