Israel’s Innovative Approach: Turning Everyday Water Pipes into Sources of Clean Electricity
In a country where water scarcity has long driven technological ingenuity, Israel has pioneered a remarkable solution to generate renewable energy from an unlikely source: the ordinary pipes that deliver water to homes, farms, and cities. Known as in-pipe or conduit hydropower, this technology installs compact turbines directly inside existing municipal water pipelines, harnessing the natural flow and pressure of water to produce electricity without building dams, disrupting ecosystems, or requiring vast new infrastructure.
How the Technology Works
Municipal water systems maintain high pressure to push water uphill or over long distances, ensuring reliable delivery. Traditionally, excess pressure is reduced using valves that dissipate energy as waste heat. In-pipe hydropower replaces or complements these valves with small, specialized turbines. As pressurized water flows through the pipe, it spins the turbine blades, driving a generator that produces electricity. This power can be fed into the local grid, used to operate nearby infrastructure like streetlights or sensors, or stored for on-site needs.
Crucially, the system only utilizes surplus pressure, leaving water flow rate, volume, and quality unchanged for consumers. The turbines are designed to handle variable flows common in urban networks, making them adaptable and low-maintenance.
Origins and Early Developments
The concept gained prominence in Israel over a decade ago through Leviathan Energy, founded by Dr. Daniel Farb. In 2012, the company introduced the Benkatina Turbine—a compact device named after an ancient Jewish high priest known for innovative water mechanisms. Engineered for underground pipes, the Benkatina could generate 20–60 kilowatts per unit and was piloted in collaboration with Mekorot, Israel’s national water carrier. Early tests demonstrated its viability, with installations in Israel and exports to regions like the Philippines.
This innovation addressed dual challenges: reducing pipe leaks caused by excess pressure (a global issue costing billions annually) while capturing otherwise wasted kinetic energy.
Recent Expansion and Real-World Impact
By the mid-2020s, Israel has scaled up deployment of these “smart pipes” across multiple municipalities. Tiny turbines embedded in distribution networks now quietly power public facilities, streetlights, digital monitoring systems, and smart-city infrastructure. In water-stressed areas, this decentralized approach contributes meaningfully to local energy needs, easing strain on the national grid.
Individual units produce modest outputs—typically in the kilowatt range—but when installed at thousands of suitable sites, the cumulative effect is significant. Municipalities report practical benefits: brighter, more reliable public lighting; reduced energy bills for local governments; and enhanced grid resilience. The technology integrates seamlessly with Israel’s advanced water management systems, including desalination plants and the National Water Carrier.
Broader Advantages and Global Potential
This form of hydropower stands out for its minimal environmental footprint. Unlike traditional dams, it avoids flooding land, altering river ecosystems, or displacing communities. It’s cost-effective, retrofitting existing infrastructure rather than demanding new builds, and particularly suited to urban or arid regions.
Driven by necessity in a water-scarce nation, Israel’s advancements exemplify pragmatic climate solutions. As cities worldwide face rising energy demands and the need for sustainable alternatives, this pipe-based approach offers a replicable model—especially for developing countries with limited resources for large-scale projects.
While not Israel’s sole hydropower effort (larger pumped-storage facilities exist for grid balancing), in-pipe technology highlights how everyday infrastructure can double as a clean energy source. In an era of escalating climate pressures, innovations like these prove that sustainable power can flow from the most unexpected places.
