Tap & Impact Fees

Our tap and impact fees apply to new connections to our water and sewer systems.  

Impact Fees

Impact fees help fund expansion of water and sewer infrastructure to accommodate growth. Water impact fees are based on the tap size. Sewer impact fees are calculated using Equivalent Residential Units (ERUs) for residential customers and Unit Contributory Loadings (UCLs) for commercial properties.  We do not charge impact fees for dedicated fire service lines.

Sewer Change-in-Use Fee

Businesses opening a new sewer account at an existing location may be subject to a one-time, non-refundable change-in-use fee to fund infrastructure costs associated with higher wastewater flows generated by the change in use of an existing facility or construction of a new facility. 

Tap Fees

They cover the cost of installing a water meter and are based on meter size. The sewer tap fee covers the cost of inspecting sewer connections made by contractors. Dedicated fire service lines are not charged a tap fee.

Affordable Housing Rate

Reduced impact fees for affordable housing are available to qualified applicants. The affordable housing rate waives the $500 engineering services charge included in the water and sewer impact fee structure, allowing a total savings of $1,000 for water and sewer impact fees. Contact the South Carolina Community Loan Fund for qualification criteria.
