Stone Traps
A Smarter Way to Manage Farm Wastewater
Built for New Zealand farming conditions, Bowers Precast Concrete Stone Traps are a robust and effective solution for removing stones, sediment, and debris before they reach your drainage or effluent systems.
Available in Standard and XL sizes, our stone traps are manufactured from high-strength precast concrete for reliable, long-term performance.
Trusted by agricultural professionals for:
- Protecting pump stations and effluent systems
- Reducing downstream blockages and contamination
- Supporting sustainable farm drainage practices

Sized for Farms Big and Small
Whether you’re managing a compact dairy shed or a large-scale operation, Bowers offers two practical options. The Standard trap suits smaller farms or lighter runoff, while the XL version is designed for higher volumes and heavy debris flow. Choose what fits your land best, with confidence in both.
