Irrigation
Sir,—Some of your correspondents overlook one. important fact when they advocate pumping water from wells for irrigation. This is the generation of electricity to run the pumps. If the Central Plains were to be irrigated entirely by pumps the electricity required could be up to 10 times the capacity of the Coleridge power station. If this were needed, dams and power stations at the gorges of both the Rakaia and the Waimakariri rivers would probably not be sufficient to provide the power required. Is this the type of development that they would support in preference to taking a portion of the flow of the Rakaia river for irrigation on the Central Plains?—Yours, etc.,
D. G. WATSON. March 2, 1982.
