Where I live, they base the sewage fees off water usage during the winter. Since few people water their yards then, it mostly takes irrigation out of the equation.
Bonus: it spurs you to think about conservation. When your 3-month wastewater averaging period starts, you know that any water you save will cut costs for the whole year.
Same here and I've thought about this, but the cost savings of doing less winter laundry for example are in the end miniscule. We pay way more for water than for sewer.
