[인도] 극심한 물 부족으로 담수화 과제 착수

인도는 소수의 가동용 담수화 플랜트를 보유하고 있지만 심각한 물 부족으로 인도 정부는 물 공급을 강화할 수 있는 방법을 다시 생각하게 되었다.

용수 공급량은 2001년에서 2050년 사이에 1인당 거의 50% 감소 할 것으로 예상된다.

결과적으로 지구 과학 연합의 하쉬 바르단(Harsh Vardhan) 장관은 당국이 담수화 과제를 전개시킬 것이라고 밝혔다.

히누스탄 타임즈(Hinustan Times)는 바르단(Vardham)의 말을 인용하여 “담수가 마르고 있는 강을 보유한 남쪽에서는 반드시 해야 한다. 담수 요구량이 너무 커서 사람들이 생존 할 수 없다.”고 말했다.

물 부족은 인도의 많은 지역에서 흔한 도전이 되었다. 지하수 공급은 격감하고 도시는 개인 물탱크와 병물에 의존한다.

INDIA TO EMBARK ON DESALINATION “MISSION” AMID CRIPPLING WATER SCARCITY

India has less than a handful of operational desalination plants but a dire water shortage is forcing the country to rethink how it can bolster water supplies.

Water availability is set to drop by almost 50 percent per person, per year between 2001 to 2050.

As a result, Harsh Vardhan, union minister of earth sciences has said that the country will be developing a desalination mission.

The Hinustan Times quoted Vardham as saying: “In deep south where the rivers have run dry desalination is a must. Freshwater requirement is so huge that people cannot survive.”

Water scarcity has become a common challenge in many parts of India, with groundwater supplies depleted and cities reliant on private water tanks and even bottled water.

Data from the World Bank predicts that by 2020, at least 21 Indian cities will run their groundwater supplies dry.

Local reports show that Tamil Nadu is witnessing its worst drought in 140 years, with the four main reservoirs – Poondi, Red Hills, Cholavaram and Chembarambakkam – now empty.

India has had some experience with desalination but on a relatively small scale compared to other nations.

The Nemmeli reverse osmosis (RO) desalination project provides 100,000 m3/day in Chennai and was developed in a joint venture led by engineering firm VA Tech Wabag. The client is the Chennai Metropolitan Water Supply and Sewerage Board.

Meanwhile the 100,000 m3/day Minjur RO desalination plant has been carried out by Indian infrastructure firm IVRCL on a design, build, own, operate and transfer basis over a 25 year period.
