A regional municipal modernization program aimed to replace aging asbestos and cast iron drainage infrastructure with modern corrugated HDPE pipe. Two regional contractors independently identified the need for dedicated production capacity to serve municipal authorities.
Both manufacturers selected corrugated HDPE as the material of choice due to superior durability in cold climates and lower long-term maintenance costs compared to concrete and metal alternatives.
Both contractors evaluated several production systems and converged on the SL600 for:
The first contractor signed their contract in Q1 2023 and received their SL600 in Q3 2023. The machine has been in production since November 2023.
The second contractor signed in Q2 2023 and received their unit in Q4 2023, beginning production in February 2024.
Facility A:
| Metric | Target | Actual |
|---|---|---|
| Daily Output | 1,200 m | 1,240 m |
| Product Diameter | 300–600mm | 300–600mm ±1.5mm |
| Defect Rate | <0.5% | 0.25% |
| Machine Uptime (annualized) | 90% | 92% |
Facility B:
| Metric | Target | Actual |
|---|---|---|
| Daily Output | 1,200 m | 1,210 m |
| Product Diameter | 300–600mm | 300–600mm ±1.8mm |
| Defect Rate | <0.5% | 0.35% |
| Machine Uptime (annualized) | 90% | 91% |
Combined, the two facilities produce 450,000+ linear meters annually, supplying the region with premium drainage pipe for municipal projects valued at €12+ million annually.
Both contractors report strong customer satisfaction and repeat orders. Facility A is now planning a second SL600 for 2025.
