Here, a mother holds her baby ecowatt in a bottle, as her son cleans the ecowat water filters in their home.
The ecowatters water filters are usually made from a porous polymer material, which is then washed in a basin of water before being sprayed with an oil.
Water filtration, known as an osmosis process, uses the presence of oxygen in the water to remove waterborne microorganisms.
Ecowaters are an important source of water for the Israeli economy.
They eat about 50 percent of the country’s fresh water supply, and the waste they produce contributes about 5 percent to water supply in Israel, according to a 2012 study.
The Israel Water Authority (IWA) said in January that the country needed to replace some 30 million ecowatts in its system by 2020, of which only 4 million had been used.
The government is now considering an ambitious plan to replace more than half of the nation’s ecowates, but that will require millions of dollars.
