Sewer Installation & SD1&2

If your project proposes a new sewer proposes a new sewer, DEP will require an SD1&2 which your engineer will create and file for approval.  This application will advise on the size, type, and connection for the proposed sewer. In addition to the new sewer main, it will note if a storm water detention or retention system is required.  Depending on what the application proposes, different regulations will apply in order to obtain permits. Your project coordinator will walk you through this process to expedite permit approval.

DEP Cross Connection

Depending on your project, a new proposed water main may require the installation of an rpz & meter.  If so, your engineer will need to create and file a DEP Cross Connection Letter (Backflow Prevention Letter).  This application will advise on the size and type of service to be installed.  In addition, it will note the size and type of rpz and meter to be installed. This approval will be required to obtain permits whether you have a ground-up project, renovation or DEP is requiring the installation of an rpz.

    The installation process will begin with the installation of the proposed sewer (if proposed). The roadway, sidewalk, and property (if applicable) will be excavated in preparation to install the sewer pipe in accordance to the SD1&2. Upon piping, DEP & DOB will inspect the new service.

    When the inspection is completed the excavations will be backfilled and restored unless a new water service is proposed.  If your project calls for a new domestic, fire sprinkler or combined water service, the excavations will be backfilled to the water main invert in preparation for the tap or wet connection.

    After the new connection is installed, the remainder of the pipe will be installed and inspected by DEP.  Upon completion of the inspection, the excavations will be backfilled and restored.  It’s important to note that these installations should only be performed by highly trained individuals. All the crew at our new construction plumbing company hold the expertise and experience to get your job done.
