LOL I think I have worse things to worry about wrt my finances. Water/sewer is probably one of the lowest cost items on my budget.
Actually this is a pretty humor filled topic and completely open to puns. I'm sure most people would find this very low on their budget. Currently, I'm on a well and septic, so I don't even have a water bill. But when I go and retire this item may actually be number 2 on my budget. (see the humor there?).
If I retire in the city, the cost in the city I desire is $60 per month for water and sewer and appears to be going up at a rate of 7-10% a year. I plan on going very low electric usage with a super insulated and tight house with heat and electric less than %50 per month on average. If I pay the home off that would leave water at number 2 after food.
I am very interested in water conservation in this respect and have chimed in or initiated several thread on this. If I use a rain collection system and a grey water recapture system along with a humanure toilet I could have a zero water bill. This would equate to 14K less I would need in the stash and about 1/2 year less of work.
If I retire in the country, I would save about 14K off my small house construction budget by bypassing the need for a well or septic field.
So yeah, it is a small thing. But I think an indicator species on how creative and forward thinking mustachians can be.
