The document is the ADS 3000 Triplewall® Sewer & Drain pipe sell sheet.

The smooth inner wall of ADS 3000 Triplewall is co-extruded with a corrugated structural core, which is laminated with a smooth white outer wall for unprecedented strength-to-weight ratio.

Applications include residential drainage, sump pump outlet, curtain drains, retaining walls, irrigation, downspout runoff, foundation/footer drainage, septic leach fields, agricultural drain outlets and parks/golf courses.

The pipe is available in 10’ (3 m) lengths and diameters are 3” and 4” (75 and 100 mm) with three different hole patterns.

The pipe is constructed with bell-and-spigot end for soil-tight joints and the outer layer provides additional resistance to effects of extended exposure to the sun’s heat and ultraviolet radiation.

The pipe provides strength and is flexible to withstand freeze/thaw conditions and continuous subzero conditions without cracking or shattering. It is corrosion resistant to acids, alkalis and salts and has many fittings options.

The specification includes pipe requirements, joint performance, material properties and installation information.

ADS 3000 Triplewall pipe has a smooth interior and exterior that meets ASTM F810 requirements and the Manning’s “n” value shall not be less than 0.009.

The pipe joints are bell and spigot and the bell ends are integrally formed on the pipe at one end to form a soil-tight connection.

The material properties are high-density polyethylene conforming to the minimum requirements of cell classification 444410C or E as described in ASTM D3350. The material formulation shall include recycled polyethylene.

Installation shall be in accordance with ASTM D2321 and ADS recommended guideline with the exception that minimum cover in traffic areas shall be one foot (0.3 m). For leachfield applications, installation shall be in accordance with ASTM F481 and as regulated by regional, state and local agencies. Proper authorization for specific applications and designs should be obtained prior to installation to ensure suitability in certain locales. Contact the local ADS representative or visit adspipe.com for a copy of installation guidelines.
