WE ARE SPECIALISTS IN OILY WATER SEPARATION
OUR HISTORY
Michael McLachlan, Managing Director of MACSEP first became involved with oil-water separation in the mid 1980’s when he managed the Environmental Division of Forgan Jones Company Ltd and was responsible for the “Sepa” agency in New Zealand.
in July 2007 Michael McLachlan acquired the assets of the New Zealand subsidiary Sepa Waste Water Treatment (NZ) Ltd and incorporated a new company Sepa NZ Limited. Sepa NZ Limited was a 100% New Zealand owned and operated company.
Sepa NZ Ltd traded under the name Sepa NZ Ltd up until February 2012 when Sepa NZ Limited was renamed MACSEP Limited.
