The 'DR' or 'DI' type Developer Relocation Process (DRP) Project Design Checklist is to serve as a guide, for engineers and WSSC personnel, for preparation and review of water and sewer construction drawings. Any questions regarding items contained herein should be referred to the WSSC Project Manager for clarification. References to the applicable page number or section in the WSSC Pipeline Design Manual are provided in columns to the right. This checklist is located on the WSSC website at wsscwater.com / Business & Construction / Development/Construction Services / Developers Forms & Fees / WSSC ePlan Review.
Engineer: Please complete the below checklist. Indicate √ = Checked; X = Not Applicable, O = Outstanding in the second column under DR Checklist Item #
Developer Relocation Projects (DRP): 'DR' Type DRP projects are for the relocation of WSSC water and/or sewer mains by a developer. 'DI' Type DRP projects are for Sewer System Rehabilitation (relining only) by a developer.
**** All 'DR' or 'DI' Type DRP plans are to be submitted and reviewed electronically through the WSSC ePlan Review (ProjectDox) system. ****
This checklist is not all inclusive. The engineer is responsible to comply with the Development Services Code and the DSD Applicant User's Guide.
