RVSS collects sewer system development charges for the three components of the sewer system: the collection system--the sewer into which your property directly ties; the interceptor--the large pipe into which the collection system flows; and the Regional Treatment Plant. If your development is within the city limits of Medford, you will pay the fee associated with the Regional Treatment Plant to Medford and the rest to RVSS. Other systems development charges that you may have paid include those for storm drain, roads, and parks--for which RVSS does not collect.
