AXL-T in-pipe hydro turbine
An inline rotor that harvests energy from water already flowing under pressure in a municipal main. No diversion. No new civil works. Just a valve-station retrofit that produces clean power for decades.
How it works in a municipal main
Most water districts carry pressurized water from a reservoir down to users. That pressure has to be reduced before it hits residential plumbing. Today, the common method is a pressure-reducing valve (PRV) that simply wastes the energy.
The AXL-T replaces or complements the PRV. Water flows through a shrouded rotor that extracts energy, pressure drops to the target setpoint, and a generator converts the rotation into grid-quality AC. Output is tied to the local utility or used behind the meter to power the water-district facility itself.
Why municipalities pick it up
- Uses infrastructure already in the ground.
- Installs during a planned shutdown window.
- Revenue or offset starts on day one of commissioning.
- Zero impact on water quality or supply reliability.
Use case: BC water districts
A mid-size BC water district with a 600 kPa head drop at a single PRV station typically sees 40 to 90 kW of continuous recoverable power. At BC Hydro commercial rates, that is a meaningful offset against the facility load and in many cases exportable to the grid. Payback windows are project-specific, but the hardware itself is engineered for a 25-year field life with annual inspection.
