Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an engineering agreement with Black & Veatch Corporation for the BWARI (Big Walnut Augmentation/Rickenbacker Interceptor) Biofilter project, CIP 650490-100002. The City of Columbus Sewer Maintenance Operations Center (SMOC) has reported difficulties in operating the existing BWARI Biofilter No. 3 and the BBX facility, located along Alum Creek Drive just south of Groveport Road at the junction/split of BWOAS (Big Walnut Outfall Augmentation Sewer) (a.k.a. BWARI Part 2), and BWOS (Big Walnut Outfall Sewer), Phase 1, (a.k.a. BWO).
The facilities have been in operation since 2007 and the Sewer Maintenance Operations Center staff have maintained these facilities. However, maintenance costs of the facilities are increasing and some of the current issues are beyond their capability.

As a consequence the city will need to evaluate these existing facilities to determine what components should be eliminated, replaced, rehabilitated or modified so that they provide the necessary level of service. Additionally, it is the desire of the City to make the biofilter facility as compatible with the newly-built Downtown Biofilters (at Liberty St. and Short St., and at Neil Ave. and Vine St.) as economically feasible, to simplify its O&M cost by the City’s SMOC workforce. The goal of this contract is to determine the items that need to be replaced/rehabilitated and the design of those repairs.
