UMich CSS benchmark model
Vacuum tubing benchmark
Use acreage and tap density to sketch a conservative vacuum tubing system before you draw the real layout.
Calculator
Based on the UMich CSS model: square sugarbush, uniform tap density, 5/16 inch laterals, and leakage load per 100 taps.
Benchmark output
A conservative sizing estimate, before field routing and terrain checks.
Mainline estimate
2,640 ft of mainline
Lateral estimate
3.4 mi of lateral tubing
Pump load estimate
at 1.25 CFM per 100 taps of leakage
How it works
The model treats the sugarbush as a square with uniform tappable tree density. It estimates tap count, groups taps into laterals, sizes a practical number of mainlines, and applies the common 1.0-1.5 CFM leakage load per 100 taps. Treat the result as a planning benchmark, not an as-built design.
Upgrade to Sapline's tubing planner
The in-app tubing planner tool lets you map mainlines and laterals, save designs, and compare field layouts.
