Description
The Klein Porto-Tower® KPT-120 is the original portable, completely self-contained water storage tower — an industry icon invented and patented by Klein Products in 1965 (U.S. Patent #3,106,171). Engineered for high-volume water recovery on demanding job sites, the KPT-120 keeps water distribution equipment working where it belongs, eliminating costly downtime caused by water truck round trips to remote fill stations.
With a capacity of 12,000 U.S. gallons and a discharge rate of up to 3,000 gallons (11356.2 L) per minute, this tower dramatically increases the productivity of water trucks, wagons, and compaction equipment on road construction, earthwork, dust suppression, and large-scale grading projects. One person can set it up in under 10 minutes — no crane or support equipment required.
Key Features
- 12,000-gallon water storage capacity — enough to keep multiple water trucks running continuously without waiting
- Discharge rate up to 3,000 gallons (11356.2 L) per minute — fills a standard water truck in under 2 minutes
- Completely self-contained — 5.5 HP (4.1 kW) air-cooled gasoline engine powers the hydraulic erection system; no external power or support equipment required
- One-person hydraulic setup in under 10 minutes — raises from towing position to full operating height at the push of a button
- Highway legal — tows as a conventional trailer with air brakes, dual 11-22.5 tubeless tires on 10-hole accuride wheels, and ICC-compliant running lights with seven-connector plug
- 10-inch discharge downspout with quick-opening/quick-closing valve and heavy-duty polyvinyl sock for fast, controlled water transfer
- 4-inch high-volume fill line for rapid tank refilling from hydrants or water trucks
- Meets current DOT standards — fully compliant for over-the-road transport

Applications
The KPT-120 excels wherever high-volume, continuous water distribution is required:
- Road construction and base compaction — maintain optimal moisture levels across large fill areas without water truck delays
- Dust suppression on haul roads and mine sites — provide a constant, high-flow supply point for dedicated water wagons
- Large-scale earthwork and grading — support continuous compaction operations without interrupting production cycles
- Mining and aggregate operations — high-discharge rate supports the heaviest production environments
- Emergency and remote water supply — self-contained design deploys rapidly wherever a stable water source is needed
