Scope

This technical information applies to the selection, installation and maintenance of MUNICIPEX reclaim pipe. MUNICIPEX reclaim pipe is intended to transport reclaimed water from the water treatment facility to the point of use. Be sure to consult your local regulations and the pipe and fitting manufacturer when selecting any piping systems for reclaimed water systems. Codes may vary significantly depending on location.

This guide gives technical information about MUNICIPEX reclaim pipe to specifiers who are selecting the appropriate piping material for new or replacement reclaimed water piping installations.

This guide gives direction to appropriately licensed installers who have a working knowledge of federal, state/provincial and local regulations. Persons using this guide must have an understanding of the principles and practices for installation of underground plastic piping systems.

This guide gives technical information about MUNICIPEX reclaim
pipe to utility managers who are responsible to maintain or modify reclaimed water lines.

It is the responsibility of the designer, the specifier and the installer to check the prevailing local codes and to verify the technical information provided within this guide is appropriate for a particular installation.

Understanding MUNICIPEX reclaim

MUNICIPEX reclaim is the REHAU trade name for our specially formulated crosslinked polyethylene pipe, also referred to as PEXa pipe. REHAU manufactures MUNICIPEX reclaim pipe in a state-of-the-art North American plant using a high-pressure peroxide extrusion method, which enhances temperature and pressure capabilities, as well as long-term strength. Fig. 1: MUNICIPEX reclaim pipe

The high degree of crosslinking in the REHAU PEXa process results in a durable, yet flexible, pipe with enhanced temperature and pressure capa- bilities, including long-term hydrostatic strength and improved resistance to slow crack growth. The capabilities of MUNICIPEX reclaim pipe make it superior for reclaimed water.

Refer to AWWA Committee Report Design and Installation of Crosslinked Polyethylene (PEX) Pipe Made in Accordance With AWWA C904 for addi-tional information on design and installation of PEX reclaimed water lines.

Industry standards

MUNICIPEX reclaim pipe meets or exceeds the following standards:

• Manufactured to SDR9 copper tube sizes (CTS) according to ASTM F876, AWWA C904 and CSA B137.5
• Certified to AWWA C904 Crosslinked Polyethylene (PEX) Pressure Pipe, 1/2 in. (13 mm) Through 3 in. (76 mm)
• Certified to CSA B137.5 Crosslinked Polyethylene (PEX) Tubing for Pressure Applications
• Certified to NSF/ANSI Standard 14 (cNSFus-rw) for reclaimed water applications
• Certified to PPI TR-3 Category 3306 for long-term hydrostatic strength, chlorine and UV resistance
• Tested in accordance with ASTM F2023 for chlorine resistance
• Tested in accordance with ASTM F2657 for UV resistance

Pressure ratings

MUNICIPEX reclaim pipe is pressure-rated for continuous use at:

• 160 psi @ 73.4°F (1,100 kPa @ 23°C)
• 100 psi @ 180°F (690 kPa @ 82°C)|
• 200 psi @ 73.4°F (1,380 kPa @ 23°C) based on a 0.63 design factor* These temperature/pressure ratings are based on an extrapolated time-to-failure prediction as defined in ASTM D2837, Standard

Test Method for Obtaining Hydrostatic Design Basis for Thermoplastic Pipe Materials. See PPI TR-3 for further explanation of these continuous-use pressure ratings.
*See REHAU Technical Bulletin 239 (TB239) for clarification.

Corrosion resistance

MUNICIPEX reclaim pipe is non-metallic. As a polymer pipe it resists corrosion in soil or aggressive water conditions. PEX pipes have been tested extensively with aggressive water conditions (pH as low as 6.5) and have been found to be resistant to corrosion over decades of service. In addition, MUNICIPEX reclaim pipe resists scaling and internal deposits. The corrosion of metal fittings is dependent on the conditions of the soil and water. Therefore, the appropriate fitting material should be selected based on environmental conditions and the application.

Fig. 2: Corrosion build-up in metal pipes Fig. 3: No internal deposits in PEXa pipes

Erosion resistance

PEX pipes have been tested with water velocities greater than 12 feet per second (3.65 m/s) without erosional effect on the pipes. If flow velocities greater than 12 feet per second are necessary, contact REHAU for further information.

Chlorine resistance

MUNICIPEX reclaim pipe can be used for chlorinated reclaimed water subject to the following conditions:

• The pH of the water is 7.0 or higher
• The free chlorine concentration is 4.0 parts per million (PPM) or lower
• Water temperature is 140°F (60°C) or lower
• Water pressure is 80 psi (550 kPa) or lower

According to ASTM F2023 the extrapolated time-to-failure of MUNICIPEX reclaim pipe at 73.4°F (23°C) far exceeds the requirements within the standard. Please contact REHAU for further information on chlorine resistance.
Additionally, according to Statement A from the Plastics Pipe Institute
(PPI), PEX pipes are also resistant to chloramines, which are found to be less aggressive to PEX pipes than free chlorine. According to PPI State-ment A, “…it is the position of PPI BCD that chloramines are less aggres-sive than free chlorine to PEX pipes. Testing of oxidative resistance using free chlorine, in accordance with ASTM F2023, will provide a conserva-tive estimate of the time-to-failure for PEX pipes when used with the disinfectant chloramines.”

Chemical resistance

MUNICIPEX reclaim pipe is resistant to a wide range of chemicals. However, while most chemicals may not harm MUNICIPEX reclaim pipe, chemical concentration, temperature, pressure and other parameters can influence the lifetime of a pipe. If you have questions regarding chemical compatibility, contact your REHAU regional sales office.

Permeation

Buried pipes
Certain organic (e.g., hydrocarbon) compounds such as fuels, solvents or other possible contaminants may permeate through plastic pipes, damaging the pipe’s integrity. This issue affects all types of buried pipes, whether they be iron, copper, PVC, PE or PEX. Even metal pipes use gaskets made of elastomeric materials which may be susceptible to per-meation by light hydrocarbons with smaller molecular sizes. Therefore, piping engineers must take special care when installing reclaimed water lines through contaminated soil, regardless of the type of pipe material. If contamination is suspected, a chemical analysis of the soil or groundwa-ter must be performed to determine the contaminant and its compatibil-ity with MUNICIPEX reclaim.

The plastic piping industry provides the following techniques for dealing with suspected contamination of soil or groundwater:

• Surround the pipe with good clean soil of Class I or Class II material to allow the suspected contaminants to dissipate into the envelope of the surrounding soil. The US EPA guidelines prohibit the reuse of excavated hydrocarbon contaminated soil in the envelope of bedding or backfill material.
• Sleeve the pipe in suspected areas
• Reroute the pipe around the contaminated area

WARNING! Do not install MUNICIPEX reclaim pipe in contaminated soil or groundwater conditions. Contaminants may damage the pipe’s integrity resulting in pipe failure.

Building penetrations
Some builders and municipalities require reclaimed water pipes to be sleeved when entering buildings. When MUNICIPEX reclaim pipes are sleeved, the space between the pipe and the sleeving must never be filled with any liquid chemical, including pesticides or termiticides. The annular gap between the pipes at the ends should be filled with silicone, latex or polyurethane expanding foam to help prevent pathways for pests and the mistaken application of harmful chemicals in the space between the pipe and the sleeving. Use only sealants that are compatible with MUNICIPEX reclaim pipes. Do not use petroleum-based sealants. See also Technical Note 39 from the Plastics Pipe Institute (PPI).

WARNING! Applying pesticides or termiticides between MUNICIPEX reclaim pipe and sleeving is strictly prohibited. Contaminants may damage the pipe’s integrity resulting in pipe failure.

Installation inside buildings
Where MUNICIPEX reclaim pipes are installed inside buildings for water supply, installers must not spray on or allow contact with organic chemi-cals, petroleum distillates, termiticides or pesticides. Any application that results in pooling or puddling of a liquid chemical on MUNICIPEX reclaim pipe is prohibited. Certain contaminants may damage the pipe’s integrity resulting in pipe failure.

WARNING! Applying harmful chemicals to MUNICIPEX reclaim pipe is strictly prohibited. Contaminants may damage the pipe’s integrity resulting in pipe failure.

UV resistance
All PEX pipes have specific UV sensitivity and must be protected from excessive UV exposure before, during and after installation. MUNICIPEX reclaim pipe has a maximum exposure limit to sunlight of up to one year and must not be permanently installed in direct sunlight, either outdoors or indoors. If installed where sunlight exposure is possible, MUNICIPEX reclaim pipe must be sheathed in an opaque, UV-blocking conduit, such as REHAU flexible convoluted polyethylene (PE) sleeving, for protection. MUNICIPEX reclaim pipe is shipped in protective packaging such as boxes. The pipe must be kept in the original packaging until time of installation, and can not be stored outdoors. Any unused pipe must be stored in UV-blocking packaging, such as the original boxes, to prevent excessive exposure. Follow all installation and storage instructions found on packaging.
NOTICE: Excessive UV exposure may cause MUNICIPEX reclaim pipes to fail, resulting in property damage and loss of water pressure. Fig. 4: MUNICIPEX reclaim coil Fig. 5: Flexible PE sleeving

Freeze resistance

Due to the lower thermal conductivity of PEXa compared with metal pipes, heat transfer through MUNICIPEX reclaim pipe is reduced. This may delay freezing of the water inside the pipe while the ground around it is below 32°F (0°C). However, water inside a pipe surrounded by frozen earth can eventually freeze. Therefore, it is a good design practice to in-stall all reclaimed water pipes, including MUNICIPEX reclaim pipe, below the frost line.

If allowed to expand along its entire length, MUNICIPEX reclaim pipe will not split when frozen. If portions of the pipe are encased in a solid mass such as concrete or hard-packed clay, then expansion of the pipe evenly along its length may be prevented, and the pipe may break if frozen.

If water in the pipe does freeze, it can be thawed as follows:

1. Thawing can be performed using available hot water injection equipment, which uses hot water to melt ice inside the pipe. This is usually performed at moderately warm temperatures. It is important to remember that the maximum water temperature allowed for thawing is 200°F (93.3°C). After thawing, MUNICIPEX reclaim pipe can immediately be put back into service.
2. Thawing can also be performed by applying hot air to the pipe. Use a hot air gun to heat frozen areas of the pipe, ensuring that the temperature of the pipe does not exceed 200°F (93.3°C). Ice should thaw long before this temperature is reached. As an alternative, a hair dryer or a warm rag may be use to thaw ice inside the pipe.

NOTICE: To avoid possible damage to pipe which could result in property damage and loss of water pressure, do not use an open flame or electric resistance thawing device to thaw MUNICIPEX reclaim pipe.

Jobsite handling

As a crosslinked high-density polyethylene material utilizing REHAU PEXa technology, MUNICIPEX reclaim pipe has greater environmental stress crack resistance than non-crosslinked polyethylene pipe (such as HDPE). This improves resistance to cracks caused by notches or scratches. While this provides a measure of safety against accidental rock impingement or scratches, REHAU recommends industry-standard installation procedures for polyethylene reclaimed water pipes. Refer to AWWA Commit-tee Report “Design and Installation of Crosslinked Polyethylene (PEX) Pipe Made in Accordance With AWWA C904” for additional information on design and installation of PEX reclaimed water lines.
When handling MUNICIPEX reclaim pipe on the jobsite, follow these general guidelines:

• MUNICIPEX reclaim pipe is shipped in UV-resistant packaging. Keep the pipe in the packaging until time of installation. Store unused pipes in the original packaging to prevent overexposure to direct sunlight.
• Open packaging with care to prevent cutting or nicking the pipes with box cutters or knives.
• When moving coils of pipes, avoid dragging on rough or sharp objects that could cut or notch the pipe. Pipes with notches more than 10% of the pipe wall thickness must be cut out and repaired according to an approved method.
• Avoid contact with petroleum products and other chemicals such as solvents and glues.
• The minimum bend radius for MUNICIPEX reclaim pipe is 5 times the pipe OD (outside diameter). To prevent kinking, bend pipes slowly, especially in cold weather.

CAUTION! Coils of MUNICIPEX pipe are tightly wound and may spring open quickly when straps are cut. To reduce the risk of injury, stand clear when opening coils and cut straps carefully.

Preparing the trench

Proper preparation of the trench bottom is an important step in laying MUNICIPEX reclaim pipe correctly. Ensure the trench bottom is smooth and free of large or sharp stones, rocks, boulders, construction debris or frozen material to avoid damage to the buried pipes.
Where suitable soil conditions exist and the trench bottom soil can be graded without difficulty, MUNICIPEX reclaim pipe may be installed directly on the prepared trench bottom. The trench bottom must provide continuous support, and be free of hollows, lumps, rocks, debris or other hard materials which could damage or kink the pipe. Any irregularities must be leveled off and/or filled with tamped material.

1. Excavation in loose rocky soil
   To provide a uniform bed for MUNICIPEX reclaim pipe, installers may over- excavate the trench bottom at least 6 in. (15 cm) below grade and restore to grade with USCS Class I or Class II granular material,tamped to at least 90% Standard Proctor Density. See 4.4 for detail on materials.

2. Excavation in solid rock
   The trench bottom must be graded with Class I or Class II granular material, minimum 90% Proctor Density, to a thickness of at least 6 in. (15 cm).

3. Unstable trenches
   Unstable soils such as mud, soft clay or peat should be stabilized in accordance with instructions from the engineer. This may require over- excavation to a depth of 12 in. (30 cm) below pipe grade, followed by refilling the trench bottom with imported granular material that will provide stable support.

4. Embedment materials
   Suitable materials based on Unified Soil Classification System (USCS):

   • Class I: Angular, 1/4″ to 1 1/2″ (6 – 38 mm) graded stone, including a number of fill materials of regional significance, such as coral, slag, cinders or crushed shells.
   • Class II: Coarse sands and naturally occurring gravels with maximum particle size of 1 1/2″ (38 mm), including variously graded sands and gravels containing small percentages of fines, generally granular and non-cohesive when wet or dry. Soil types GW, GP, SW and SP are included in this class.

Making connections

For reclaimed water lines and underground applications, it is the responsibility of the installer to ensure fittings selected meet jurisdictional codes.

Fittings
MUNICIPEX reclaim pipe is a Copper Tube Size (CTS) SDR9 pipe that can be used with AWWA C800 compression joint brass valves and fittings for underground connections. These connections must be made with a plas-tic or stainless steel insert inside the pipe to allow proper compression at the joint. These inserts are available from waterworks wholesalers.
By using these inserts, MUNICIPEX reclaim pipe can be attached to compression joint connections in the same manner as type ‘K’ copper or CTS SDR9 polyethylene tubing.

Fig. 6: Compression joint valves Fig. 7: Pipe inserts, metal or plastic

Before connections are made, inspect pipe and remove all dirt and foreign matter from the interior and ends of the pipe. Follow fitting manufacturer’s instructions for assembly of compression joints. See Appendix A.

Ensure there is no angle or misalignment where pipe connects with compression joint connections. MUNICIPEX reclaim pipe must connect straight into each joint, and there must be no stress on the connection. Bends in the pipe must be no less than 10 pipe diameters from any fitting or valve.

Alternatively, other approved PEXa fittings, such as a cold-expansion compression-sleeve fitting system, may be used for connections to valves, saddles, taps or meter housings (check local codes and approvals). Follow fitting manufacturer’s instructions for assembly of compression-sleeve fittings.

Tools
No special tools are required for MUNICIPEX reclaim pipe connections when using AWWA C800 compression joint connections. Standard pipe wrenches may be used with these connections, as per the manufacturer’s instructions. Fig. 8: Standard tool and connections

Cutting pipe
MUNICIPEX reclaim pipe must be cut squarely using an approved plastic pipe cutting tool, such as those sold by REHAU. Do not use a hacksaw or knife to cut MUNICIPEX reclaim pipe, as a rough cut may prevent a secure connection.

Fig. 9: Plastic pipe cutter

NOTICE: Using a hacksaw or knife to cut MUNICIPEX reclaim pipe may cause a rough or jagged cut and an improper connection with the fitting, resulting in a leak, potential property damage or loss of water pressure.

Gooseneck

At the connection between MUNICIPEX reclaim pipe and the reclaimed water main, MUNICIPEX reclaim pipe should leave the main at a 10 to 20° angle above the horizontal, to prevent stress on the connection. This will result in a ‘gooseneck’ in the pipe that should be at least 4 ft (1.2 m) long. It is not required to use the higher 45° gooseneck common with copper service line.

Fig. 10: Angle MUNICIPEX reclaim pipe 10 to 20° above horizontal at connection to main

Placing MUNICIPEX reclaim

Transport and install pipe carefully to prevent damage. Do not drop or dump MUNICIPEX reclaim pipe into the trench or drag MUNICIPEX reclaim pipe over sharp objects.

Snaking pipe

MUNICIPEX reclaim pipe should be laid with sufficient slack to accom-modate contraction of the pipe due to cooling, or expansion of the pipe if it was colder than normal ambient soil temperature when installed. This is accomplished by snaking MUNICIPEX reclaim pipe in the trench, with side-to- side offset of approximately 1% of the length of the pipe between connections for every 18°F (10°C) of expected temperature change. Snaking will also allow the pipe to expand gradually over a larger area if it expands, rather than at one specific point. See Table 1 for recommended offsets.

MUNICIPEX reclaim pipe will expand or contract approximately 1 in. per 10°F temperature change per 100 ft pipe length (5 cm per 10°C per 30 m pipe length).

Example:
50 ft length of pipe cools from 90 to 60°F after installation: Temperature change = 90 – 60 = 30°F
Contraction = 30°F x 50 ft x 1 in./10° x 100 ft = 1.5 in. contraction of length

Minimizing waste
MUNICIPEX reclaim pipe has consecutive footage marks printed on the pipe to assist with determining the length of installed pipe and the amount remaining on a coil. With careful planning, this helps to reduce pipe waste and the requirement for couplings.

Repairing kinks
MUNICIPEX reclaim pipe is more flexible than non-crosslinked HDPE pipes and will resist kinking even at temperatures well below freezing. However, if MUNICIPEX reclaim pipe is bent too tightly and kinked, it can be repaired without cutting.
To repair a kink, carefully heat the kinked area with a hot air gun until the kink disappears and the pipe becomes round (approximately 275°F [135°C]). Then remove heat and let the pipe cool before moving it. Fig. 11: Repair kinks using hot air
To prevent deformation of the pipe, there must be no pressure or stress on the pipe during heating. Small bubbles or wrinkles may appear on the purple UV shield – this is normal. Kinking can be pre-vented by bending the pipe more slowly in cold temperatures.

NOTICE: Do not use an open flame such as a torch to repair kinks, this may overheat the pipe and cause permanent damage. Overheated pipes may fail prematurely resulting in property damage and loss of pressure.

WARNING! Do not heat pipe that is under pressure. Pipe that is heated while under pressure can expand and burst, resulting in injury.

Backfilling trench

Backfill
Cover the installation of MUNICIPEX reclaim pipe with backfill as soon as possible to help protect the pipe from shifting, UV exposure, or damage by other construction trades.
Since MUNICIPEX reclaim pipe is resistant to impacts, abrasion and cracking, the excavated native material can be reused for the pipe em-bedment zone as per ASTM D2774 and to backfill the remainder of the trench.
Unless otherwise specified, trenches under pavements, sidewalks or roads should be backfilled and compacted to at least 90% Standard Proc-tor Density. In traffic areas, MUNICIPEX reclaim pipe must be installed per local code requirements. In addition, the installer should follow good installation practices as defined by AWWA, AASHTO, and PPI for under-ground piping applications.

External loads

• The effects of distributed earth loads with MUNICIPEX reclaim pipe which is properly installed are negligible.
• Loading caused by construction activities and traffic should be pre-vented by using a minimum cover of 24 in (60 cm) of proper backfill material, compacted to at least 90% Standard Proctor Density.
• Concentrated loads must be avoided to prevent damage to the pipe and/or reduction in water flow.

Installing MUNICIPEX reclaim using Horizontal Directional Drilling

Horizontal Directional Drilling (HDD) is becoming a more commonplace method of pipe installation. HDD is allowed with MUNICIPEX reclaim pipe. Even though it is resistant to scratches, MUNICIPEX reclaim pipe must be installed using industry-standard HDD techniques for HDPE polyethylene pipes of the same sizes.
Note: The Typical Safe Pull Stress for MUNICIPEX reclaim pipe is approximately 2,000 psi (13.79 MPa) at 73.4°F (23 °C) for 30-minute duration. Exceeding this stress could cause deformation (stretching) of the pipe. Specifiers and installers are advised to refer to the following publications for recommendations on Horizontal Directional Drilling techniques:

• American Society of Civil Engineers (ASCE), Manual of Practice 108 Pipeline Design for Installation by Directional Drilling
• The North American Society for Trenchless Technology (NASTT), Mini-Horizontal Directional Drilling Manual
• The Plastics Pipe Institute (PPI), Handbook of Polyethylene Pipe, Chapter 12
• American Water Work Association (AWWA), M55 Manual of Water Supply Practices, Chapter 8
• The Plastics Pipe Institute (PPI), TR46 Guidelines for Use of
  Mini-Horizontal Directional Drilling for Placement of High Density Polyethylene Pipe

Working with installed MUNICIPEX reclaim

Locating buried MUNICIPEX reclaim
Available methods for locating buried MUNICIPEX reclaim pipes include metallic detection tape or copper tracing wire, as required by the respon-sible municipal authority. Tracer wire may be secured to MUNICIPEX reclaim pipe with nylon ties. Do not use adhesive tape to attach a tracer wire to the pipe.
NOTICE: Do not use adhesive tapes on MUNICIPEX reclaim pipe. Certain adhesives may cause the pipe to fail prematurely, resulting in property damage and loss of pressure.

Using squeeze-off technique
The water flow in MUNICIPEX reclaim pipe may be stopped using a me-chanical line squeeze-off tool designed for PE gas pipes. This technique is safe due to the high degree of crosslinking in MUNICIPEX reclaim pipe and the flexibility of the pipe. Fig. 12: Pipe in squeeze-off tool Fig. 13: Closing pipe

Using a squeeze-off tool to temporarily stop the water flow through MUNICIPEX reclaim pipe will not cause permanent damage or deforma-tion to the service line, and is the fastest and cleanest way to temporarily stop flow through the pipe, such as when replacing a curb stop or other shut-off valve. Fig. 14: Pipe after removal of tool Fig. 15: Re-rounding pipe

The thermal memory of MUNICIPEX reclaim pipe allows the pipe to
re-round itself almost completely to its original shape, depending on temperature and time. To completely re-round the pipe, simply rotate the same squeeze-off tool 90° and push on the pipe. With less down time, the water line is back in service quickly. MUNICIPEX reclaim pipe can withstand this mechanical crimping without permanent damage or deformation.

For questions about these instructions or about MUNICIPEX reclaim pipe specifications, contact your regional REHAU sales office.
