Centennial Technology participates in governmental research program for the protection of marine Environment in Lake Shihwa. CT made a contract with Ministry of Maritime Affairs and Fisheries (MOMAF, http://www.momaf.go.kr/eng/main/main.asp) in March 31, 2006. Packaged wastewater treatment system installed in Wooem island and KORDI will be operated and tested by CT. Nonpoint pollution treatment system at Sinkil stream will be also operated. The experience of facility management would give us much benefit to gain experience in these area.
