The majority of Solebury is Well Water (and septic systems) so there are no bills for water / sewer. (other than routine maintenance that is) (I'm a resident of Solebury).
Are you referring to one of the newer developments where there is usually a large "shared" well. In those (few) areas you DO have a monthly bill for water usuage (and sewage disposal) and those fees (last I checked) did seem a little higher than some surrounding areas that have "true" Public Water and Sewer Service.
If you are looking in the area, I'd be glad to help answer any questions you may have regarding that.
