We pay flat fee for sewer/water/trash/stormwater/recycling admin, and only water (and by proxy sewer) is metered based on usage. So no go on the dumping 3x per year. And I don't think my neighbors would like the trash out there.
I have noticed that we apparently aren't being good trash producers. Our family of five rarely fills the 96 gallon can in a week, and we often go 2-3 weeks without taking the can to the curb. Other neighbors that only have 1-2 people living in their houses have slam full cans every week. And we have a 1 year old cranking out the dirty diapers!
We recycle plenty, but don't compost. I think the lack of trash production is due to not going recreational shopping every day, and buying mostly non-prepared food items and rarely getting take out. For example, the waste from a single serving frozen tv dinner is more bulk than the waste from a 1 lb box of pasta, a jar of sauce, and fresh veggies. If we composted the veggie scraps, everything else would be recycled and not produce waste.
