Plumbing and Fuel Gas Plan Review Prescreen Checklist for ePlan Review
The Plumbing and Fuel Gas Plan Review Prescreen Checklist is to serve as a guide, for permit applicants and WSSC personnel, for preparation and review of plumbing and fuel gas ePlan review. Any questions regarding items contained herein should be referred to WSSC Intake Staff (301) 206-8650; [email protected] or Plumbing Plans Review staff for clarification. This checklist is located on the WSSC website at wsscwater.com / Business & Construction / Regulatory & Licensing Services / Plan Review Information.
**Beginning July 1, 2019, all plans submitted will be "Prescreened" and subject to the published "Rejection" fee; adhere to all checklist items (in blue); items is red are "rejectable" and subject to the referenced fee.
***Beginning Sept 1, 2019, all projects requiring plans review shall be submitted electronically through WSSC's ePlans Review
ePlan Review Process - To get started, complete a Long Form Plumbing Permit Application (found on the WSSC Permitting Services website) and submit online. Permit Services will verify the address and WSSC water and/or sewer billing account number provided on the application. It is important that the proper contact types are established by the permit applicant. The ‘Principal Master’ is the default contact with full control of the ePlan Review submittal process, unless a ‘Plans Submitter’ contact is designated. The ‘Plans Submitter’ contact type allows the ‘Principal Master’ to delegate the plans review submittal process while still having access to view progress. If a design engineer is to act directly (without a licensee) on behalf of the project they must be designated as the ‘Plans Submitter’ by the permit applicant. WSSC will send an email invitation and provide a project number to the applicant to upload Plumbing and Fuel Gas (PFG) plans into ePlan Review.
For a detailed overview of the ePlan Review process refer to the RSD Applicant Guide linked at the home page of ePlan Review (https://planreview.wsscwater.com/ProjectDox/).
