Proposed Collector Well 112 (CW112) is to be located south of PAWP on Parcel 34 (east of Parsons Avenue / north of London-Groveport Road / south of Big Walnut Creek). The raw waterline from CW112 will tie into the existing 42” raw waterline from CW106 along Parsons Avenue.
Preliminary and detailed engineering have been accomplished under this contract with Arcadis US, Inc. This modification is for Arcadis US, Inc., to provide Engineering Services During Construction.
