Our history

SECA (Services Camerounais d'Assainissement S.A.) was created in 1974 at the initiative of the HYSACAM Group

Having its Head Office in Douala, SECA has for 47 years collected and transported hazardous and non-hazardous waste. Active on the Cameroonian market, SECA works with some public and private bodies in transporting industrial and hazardous waste, both solid and liquid.
