We just moved into a new home which has sprinklers throughout. Much to our surprise, we received a separate bill from PWD for $23.79/mo for "Fire Service Charge (Service 42P)". Is this accurate? I'm not sure why we have to pay extra to have sprinklers in our home, on top of our normal water bill? And if that's the case, does that sound like the right service code (42P) as $285/yr just to have sprinklers in our home (which aren't even using any water) seems VERY excessive.
