The Town of Enfield currently funds the sewer program through a portion of the local property tax. This type of sewer funding system called "Ad Valorem" is difficult to sustain. Each capital sewer improvement project puts pressure on the Town’s budget and the Mill Rate. Investments in sewer upgrades often lose out to the Town's other immediate capital needs, like schools and public safety (police, ambulance and fire). Historically, Enfield has been challenged to allocate the money required to bring the current sewer system up-to-date.
Additionally, a sewer use charge billed directly to each household and business owner based upon their specific water consumption would provide the town with a more equitable means of sharing sewer costs. Households that conserve water would pay less than high-volume sewer users. This change would likely be more attractive to residents, the commercial and industrial community, and it would provide the town with additional external funding resources not available to municipalities that use property tax-based funding systems. For instance, under the property tax model, many joke that your car pays for sewer service.
