System Development Charges FAQ

121766

System Development Charges are one-time charges assessed when customers connect to system. These charges help pay for the sanitary sewer and surface water infrastructure required to meet growth-related needs. The current sanitary sewer SDC fee is $8,860 per equivalent dwelling unit (EDU) for each new sanitary sewer connection throughout the WES Service Area. The current surface water SDC fee is $240 per equivalent service unit.

Adjustments to these rates are made during the budget process and go into effect each July 1.

121766

Based upon the recommendations received from the WES Advisory and Budget Committees, the Board of County Commissioners, whom also serve as WES’ governing body, approves SDC rates. Rates are adopted to offset the impacts of growth on infrastructure while maintaining the competitiveness of local businesses.

121766

SDCs are paid when property owners request new or expanded sewer service connections though building permits issued by cities or the county.  Some of those payments are collected by cities and routed to WES, while some are paid directly to WES during the permitting process. 

121766

Projects that do not increase the use of or impact the sewer system are exempt from SDCs. 

Credits are available for projects that offset the impact of the new connection on the system, such as when commercial and industrial users recycle wastewater and stormwater. 

Waiving SDCs is not an option.

Each year WES goes through a budget process, typically from January through June, to establish rates for the following fiscal year (July 1 to June 30).  Public meeting notices are published, inviting the public to comment on the proposed rates and fees before the budget is adopted. A notice regarding the SDC rates is published as required by applicable law.

Community members are welcome to attend budget committee meetings or to testify at a Board of County Commissioners Business meeting before the budget is formally approved in June.  

In addition, the Commissioners seek feedback from ratepayers, elected officials, developers and business representatives that serve on the WES Advisory Committee.
