HDPE pipe has proven to be the pipe of choice in many industrial applications because of its non-conductivity, extreme strength, durability, flexibility and resistance to chemicals and corrosion. These qualities of high-density polyethylene offer engineers and contractors a significant design and installation advantages over traditional pipe materials.

Sustainability, service life, and lifetime costs – HDPE pipe and fittings meet the highest industrial and environmental standards today while offering tremendous long-term value to your customers.

It is made of 3 or 4 slotted corrugated pipe, surrounded by NDS poly-rock, and wrapped in a geotextile fabric. It's durable, crush-proof and has a 100-year lifespan. The NDS French Drain has been designed to take water out of the soil and pipe it to a safe discharge point like an NDS Flo-Well or Pop-Up emitter. ERW Slotted Steel Pipe.

Objective
A Florida power plant employed a salt water condenser system made from PVC pipe. Because of the extreme UV environment, the system became inefficient at most couplings and joints due to leaking, cracking and high maintenance costs.

Solution
The solution was to replace the entire condenser system with HDPE pipe and components. The ability to weld all pipe and fitting joints allowed the integrity of the entire system to be far superior to the previous glued PVC system.

Most importantly, HDPE pipe’s resistance to UV proved to be a superior material for this unique environment. The ease of use plus the low material cost was a factor in determining a high return on investment with HDPE.

Result
The ability to join HDPE to other materials proved to be a time and cost savings for the customer. With HDPE, the leakage due to previous bad fittings and abrasion was eliminated immediately. The total return on investment was also greatly improved when the longevity and near-maintenance-free feature of HDPE was considered. HDPE proved itself to this customer and to the power industry as a material of choice for replacing worn and outdated condenser systems.

Section 61 Drainage Facilities—General

4-6101 General

The requirements in Section 61, “General,” of the Standard Specifications include general specifications for constructing drainage facilities. These requirements and the guidance in this section apply to other drainage sections of this manual. This section provides inspection guidelines for:

• Culvert and Drainage Pipe Joints
• Alternative Culverts
• Alternative Slotted Pipe
• Concrete Backfill for Pipe Trenches
• Temporary Culverts

When the Bid Item List includes items for alternative pipe culvert, the contractor chooses from the list in Section 61-3, “Alternative Culverts,” of the Standard Specifications.

Refer to the following sections of this manual for inspection guidelines of the culvert type selected by the contractor:

• Section 4-51, “Concrete Structures,” for reinforced box culverts.
• Section 4-64, “Plastic Pipe,” for high-density polyethylene or plastic pipe.
• Section 4-65, “Concrete Pipe,” for reinforced concrete pipe.
• Section 4-66, “Corrugated Metal Pipe,” for corrugated steel pipe and pipe arches; or corrugated aluminum pipe and pipe arches.
• Section 4-67, “Structural Plate Culverts,” for structural steel pipe, arches, and pipe arches; or aluminum plate pipe, arches, and pipe arches.

When the Bid Item List includes items for alternative slotted pipe, the contractor chooses from the following types:

• As shown in Section 64-3, “Slotted Plastic Pipe,” of the Standard Specifications, or equal.
• Slotted corrugated pipe.

For inspection guidelines for slotted plastic pipe, refer to Section 4-64, “Plastic Pipe,” of this manual. For inspection guidelines for corrugated pipe, refer to Section 4-66, “Corrugated Metal Pipe,” of this manual.

4-6102 Before Work Begins

Before work begins, do the following:

• Review the special provisions and contract plans to determine the different types of culvert that may be used and the locations where alternative culverts may be installed.
• Review the special provisions and contract plans to determine the different types of slotted pipe that may be used and the locations where alternative slotted pipe may be installed. Do not mix different types of slotted pipe.
• Verify that Form CEM-3101, “Notice of Materials to Be Used,” includes all materials. Refer to Section 6-202, “Responsibilities for Acceptance of Manufactured or Fabricated Materials and Products,” of this manual for additional information.

4-6102A Culvert and Drainage Pipe Joints

Ensure the contractor submits test results or a mathematical analysis of the joint materials for joint systems specified as watertight.

4-6102B Concrete Backfill for Pipe Trenches

Concrete backfill for pipe trenches must comply with specifications for minor concrete, except the concrete must contain at least 380 pounds of cementitious material per cubic yard.

When rapid strength concrete is to be used as concrete backfill, ensure that the contractor submits the mix design and test data at least 10 days before excavation of the pipe trench. Review the mix design, test data, and cure time required for the concrete mix to attain 500 psi (pounds per square inch) compressive strength.
