Lincoln Area Sewer Separation

Lincoln Area Sewer Separation, Portsmouth, NH

Lincoln Area Sewer Separation located in downtown Portsmouth, NH is the largest pipe project that Severino Trucking has had to date.  The main purpose of this $5.5M project is to separate the storm water system from the sewer system.

In order to do this, 2500 lf of new 30" PVC sewer main will be installed along with 850 lf of 24", 550 lf of 12", 440 lf of 10" and 2200 lf of 8" that will connect six side roads and re-route 1300 lf of cross county sewer that now exists.  One hundred thirty homes will also have new sewer services installed.

The storm water that currently runs into the sewer system will now run in a new drainage system consisting of 1700 lf of 48" RCP pipe along with 4500 lf of new drainage pipe that ranges from 12" to 42".

Not to be left out is the installation of 3800 lf of 12" DI water pipe and 2400 lf of 8" DI water pipe along with almost 4,000 lf of service pipes to the existing homes.

This is a particularly challenging job not only because of the tight quarters, but the depth of the pipe (up to 18') and the 12' of ledge that needs to be removed.  The project began on September 7, 2010 and is scheduled for completion summer of 2012.
