HDPE/CMP Pipe Systems
HDPE and CMP Pipe Systems for Stormwater Conveyance
Durable HDPE and CMP pipes deliver reliable stormwater conveyance with long service life.
Nexterra’s HDPE and CMP Pipe Systems provide proven reliability and performance for stormwater conveyance and storage infrastructure. Trusted for decades, these materials combine the best of flexibility, corrosion resistance, and structural strength to meet demanding municipal, industrial, and transportation project needs.
Proven Materials, Modern Solutions
For over fifty years, High-Density Polyethylene (HDPE) has been chosen for water conveyance projects for its high tensile strength, resistance to impact, and thermal stability. HDPE’s flexibility allows it to accommodate shifting soils and heavy loads, reducing cracking risks and maintenance needs. Its recyclable design advances environmental responsibility, lowering life-cycle costs.
Corrugated Metal Pipe (CMP) brings a century of structural strength and durability to drainage, culverts, bridges, and foundation applications. Available in various steel thicknesses with corrosion-resistant coatings, CMP delivers long-lasting performance under extreme soil pressures and traffic loads.
Together, these options deliver hydraulic efficiency and structural resilience across diverse stormwater conveyance projects, from sewers and culverts to detention and retrofit installations.
HDPE Pipe Advantages
- Lightweight design accelerates installation and lowers labor expenses
- Smooth interior minimizes sediment buildup and maintains flow
- Resistant to corrosion, chemicals, and root intrusion
- Flexible walls maintain integrity in unstable soils
- High strength-to-density ratio balances durability with economy
- 100% recyclable for sustainable construction
CMP Structural Benefits
- Multiple steel gauges for customized load-bearing capacity
- Galvanized and aluminized coatings extend lifespan
- Proven durability over decades under rigorous conditions
- Performs reliably in deep burial and heavy loading
- Trusted choice for transportation infrastructure and long-term projects
Upstream and Downstream Integration
Nexterra’s pipe systems integrate effortlessly into comprehensive stormwater management networks. Upstream, runoff collected from impervious surfaces is guided via engineered gutters into HDPE and CMP pipes designed to reduce flow velocity and sediment transport, protecting infiltration and conveyance systems.
Downstream, these pipes connect with erosion control products, hydrodynamic separators, underground detention basins, and biofiltration systems. This integration extends detention times, improves pollutant removal, enhances groundwater recharge, and supports low-impact development (LID) goals while maintaining watershed health.
Structural and Hydraulic Excellence
Nexterra’s HDPE Pipe Systems offer exceptional durability and hydraulic performance with service lives typically exceeding 50 years. Featuring smooth interior walls for optimized flow and reduced clogging, HDPE pipes adapt flexibly to soil movement and load shifts which helps prevent cracking and infrastructure failure. These pipes resist corrosion, chemical attack, and root intrusion, making them ideal for a wide variety of municipal, industrial, and transportation stormwater applications where resilience and longevity are paramount.
Corrugated Metal Pipe (CMP) Systems deliver robust structural strength and proven longevity, with typical service lives approaching 100 years. Manufactured in multiple steel gauges with corrosion-resistant coatings, CMP resists extreme soil pressures and heavy traffic loads often found in culverts, detention basins, roadways, and foundation drainage. CMP’s engineered design maintains hydraulic efficiency in demanding environments while providing the necessary rigidity to support enduring infrastructure. Both HDPE and CMP pipes meet strict compliance requirements including MS4, TMDL, and various transportation standards, contributing to sustainable stormwater management through infiltration enhancement and runoff reduction.
Key performance benefits include:
- Exceptional service life supporting long-term infrastructure investment
- Hydraulic efficiency through optimized flow and clog resistance
- Structural resilience adapting to challenging soil and load conditions
- Compliance with rigorous environmental and transportation standards
- Promotion of green infrastructure principles through runoff reduction and infiltration
This blend of durability, performance, and regulatory alignment offers contractors and engineers a reliable foundation for stormwater management projects requiring proven, lasting solutions.
