Channel Poly Bayoutlets & Crossings
Poly Outlets, Risers & Crossings
Modern, Reliable Solutions for Efficient Water Management
At W&P Pumps, we supply and install a full range of polyethylene (poly) outlets, risers, screw-downs, and lockdown flaps for agricultural irrigation and flood irrigation systems.
Designed to outperform traditional concrete bay outlets and checks, poly outlets offer a modern, cost-effective, and more durable alternative for today’s irrigation operations.
Why Choose Poly Outlets Over Concrete Bay Outlets?
While concrete structures were once the standard for irrigation systems, poly outlets offer major advantages that can significantly improve the efficiency and longevity of your water management infrastructure:
Lightweight and Easier to Install
Poly outlets are far lighter than concrete, allowing for faster, easier installation without heavy machinery. This reduces labour and installation costs, and enables quicker project turnaround.
Flexibility and Ground Movement Resistance
Poly is far more flexible than rigid concrete. It can absorb minor ground shifts and soil movement without cracking or breaking, ensuring your infrastructure remains watertight and functional for many years.
Superior Corrosion and Chemical Resistance
Unlike concrete, poly outlets are not affected by soil acidity, water quality, or chemical exposure. They are highly resistant to corrosion, rot, and erosion — even in aggressive environments.
✔ Reduced Maintenance Costs
Poly systems require minimal maintenance over their lifespan. No cracking, spalling, or expensive patch repairs like you might encounter with aging concrete structures.
✔ Customisable to Your Needs
Poly outlets can be tailored in size, fitting type, and flow control options to suit your specific irrigation layout, flow rates, and management preferences.
✔ Cost-Effective Over the Long Term
Although initial costs are competitive, the real savings are seen over the long term — with lower maintenance, longer service life, and faster installation translating into a much lower total cost of ownership.

Lockdown Flaps — Secure, Reliable Water Control
Lockdown flaps are a critical addition to any bay outlet or pipeline termination.
Our poly lockdown flaps are designed to:
Prevent backflow during flood events or channel surges.
Reduce the risk of debris entering the pipeline system.
Provide secure, automatic closure without the need for constant manual intervention.
Handle high flows while maintaining minimal flow resistance when open.
Built from high-grade materials, our lockdown flaps are UV-resistant, corrosion-proof, and made to handle the tough conditions of Australian irrigation systems.

Screw-Down Risers & Bay Outlets — Fine Control at Your Fingertips
Screw-down risers (also called riser bay outlets or screw-down valves) are a popular choice for operators wanting precise control over water delivery into bays or channels.
Advantages include:
Easy manual control of water flow height and volume.
Strong seal for stopping water flow completely when required.
Durability under constant pressure and exposure.
Adjustability for managing variable crop watering needs.
Our poly screw-down risers are robust, lightweight, and built for long service life with minimal maintenance, even under frequent use.

Poly Crossings — A Better Way to Build Checks and Driveways
Replacing concrete checks and crossings with poly crossings brings major benefits:
Faster Installation: Pre-manufactured poly culverts or crossings can be installed quickly without large formwork or curing times.
Reduced Erosion: Smooth interior surfaces reduce scouring and water turbulence.
Flexibility: Poly pipes flex slightly under load and movement, reducing the chance of cracking compared to concrete.
Lower Cost: Installation and maintenance costs are significantly lower over the lifespan of the structure.
Custom Solutions: Crossings can be easily scaled to required flow capacities and fitted with wing walls, headwalls, or flap gates if needed.
Poly crossings are an excellent choice for farm traffic, machinery, and flood control, providing safe, reliable access while protecting your irrigation network.
