More than a hundred army engineers laid 24 pipelines stretching for 124 kilometers connecting artesian wells in the western part of the peninsula with the Crimean canal.
Ukraine’s attempts to cut off water supplies to Crimea caused significant droughts last summer, but now Russia has rushed to compensate for the deficit.
Before joining Russia in March, Crimea was recieving up to 85 percent of its water needs through a canal stretching from the Dnepr River.
Kiev closed the floodgates of on April 26 last year and built a dam that blocked freshwater supplies.
The Crimean authorities have repeatedly asked Kiev to negotiate water supply contracts.
But Kiev is keeping up the pressure on Crimea whose agriculture sector is fully dependent on irrigation supply.
