Uses the kinetic energy and water-hammer effect of a continuously flowing source (stream, river, spring with sufficient fall) to lift a fraction of that flow to a higher point, entirely without electricity, fuel, or lubrication, some documented installations have run continuously for decades. Genuinely site-dependent: needs a reliable flowing water source with roughly 10%+ slope and a real fall height between source and pump; not usable without one.
Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.
Flowing water source (stream/river/spring) with sufficient fall/slope on site
No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
