Part of our core business is the provision of operating and maintenance services in the water and wastewater industries. We have established ourselves as one of the leading Design-Build-Operate (DBO) contractors in Hong Kong in water and wastewater. At their peak, our Operation and Maintenance (O&M) teams have operated 53 municipal sewage facilities and provided maintenance services for over 100 such facilities simultaneously, all in Hong Kong. We design wastewater plants from the perspective of our end-users’ requirements. Based on the design objectives of wastewater facilities, we are able to bring performance to an optimum level through our expertise in operations and maintenance. We have established robust supply chains with equipment manufacturers and suppliers to provide after sales services and spare parts for the electrical and mechanical (E&M) equipment needed for operation and maintenance.
