Wow that is high. What all goes into the tap fee?
It is different per city/county, tap/permit fees have really big swings these days as cities have begun to use tap fees as an income bucket, like they are doing more with sky rocketing taxes. What the city does as part of the tap per lot (inspecting it, excavation, making connection, meter, etc) will also vary greatly per city. You have to add all those fees + your plumber costs to forecast it.
