Many farmers use their irrigation pumps to fill reservoirs, but these units are generally set up to supply high pressures rather than the high volumes needed to fill a reservoir, says Northamptonshire-based Briggs Irrigation.
Its answer is a purpose-built reservoir pump-set powered by a four-cylinder JCB diesel engine.
Features include a water level sensor that gives the option of linking engine speed to water levels in the watercourse. That means that as water levels in the stream or river rise, the pump automatically increases extraction rate (within the term of the extraction licence).
The first unit, installed at a new reservoir near Newmarket, has an output of 100-400cu m/hr.
