2. History of research projects
As shown in Table-1, with regards to water purification technology, research started in 1991 with
Pilot Plant for MF/UF Membrane (MAC21), then went on to Pilot Plant for NF Membrane (Advanced-
MAC21). Next came R&D on High-Efficiency Water Purification Technology (ACT21). Following that
there was R&D on Sustainable Water Purification Technology (e-Water), which finished the fiscal year
before last, and now we have the 5th project, R&D on the Establishment of Advanced Water Purification
Technology for Safe and Palatable Water (e-Water II). Pipeline technology research and development
projects also began in 1996, and after finishing research on a water service system without receiving tank
