Installation Cost of PE Pipe for a Gravity Sewer
Installation Cost of PE Pipe for a Gravity Sewer
(OP)
I am currently working on the sewer line layout for an 80 acre residential development in South Louisiana and am looking into specifying P.E. 3408 pipe instead of PVC. The architect who did the site layout went with a "Cove" design, so there are winding roads throughout. Using PVC, I came up with a very large quantity of manholes that would be required due to changes in direction throughout the development. To make matters worse, the parish does not allow sewer manholes within the street, so I am forced to work with about 12' between the road and edge of the ROW where these manholes can be placed. I'm thinking with the P.E. pipe I can reduce the number of manholes considerably. However, the cost estimating software I have only has material and labor costs (no equipment costs) for P.E. pipe, and it's actually lower per foot than the cost to install PVC. Does anyone have a general rule of thumb as to how much P.E. pipe costs per linear foot installed? This will be the driving force in specifying the type of pipe to use.
Thanks in advance.
Thanks in advance.

bimr, it will be a gravity sewer.

Other than the cost difference for the materials, one would expect the installation cost would be similar.

"In general, sewers 24 inches (600 mm) or less shall be laid with straight alignment between
manholes. Straight alignment shall be checked by either using a laser beam or lamping.
Curvilinear alignment of sewers larger than 24 inches (600 mm) may be considered on a case by case
basis provided compression joints are specified and ASTM or specific pipe manufacturers' maximum
allowable pipe joint deflection limits are not exceeded. Curvilinear sewers shall be limited to
simple curves that start and end at manholes. When curvilinear sewers are proposed, the
recommended minimum slopes indicated in Paragraph 33.41 shall be increased accordingly to provide a
minimum velocity of 2.0 feet per second (0.6 m/s) when flowing full."

The local sewer agency would have to accept the piping material. If I was in their place, I would not accept it as it is too flexible.
To avoid wasting your time, you should run these questions by the local sewer agency.

The additional effort and labor required to remove the internal beads is minimal.
