Need Utility Benchmark Data: What is a reasonable water Bill ?? Help

[Nicolas Vinot]

After I asked my plumber to come to my properties and look for leaks, I came to the conclusion that my quadruplexes have huge water bills (water taxes?) and there is nothing I can do... I live in Grosse Pointe (nice neighborhood close to Detroit). Each of my quads have "fixed" water cost, every 2 months, billing shows (and that's not the water usage line): Detroit sewage: $89.00 Recycling: $16.96 Detroit water: $144.64 Total : $250.60 Per year: $1,503.60 So for 2 quads: $3,007.20. If I don't pay my water bills for a year, it will be a fixed $3,000 tax + tenants' water usage. It goes up quickly... Does that sound normal for 8 units? (2 x 4). Do we have (state by state) benchmark utility cost data I can use to compare my bills to? Nico
