Heerema Marine Contractors (HMC) is a global contractor in the international offshore oil and gas industry. Because of the strategic importance to the offshore industry of the harbour city of Porto Amboim (Angola), HMC is also active in Angola. Heerema Porto Amboim, a subsidiary of HMC, has 150,000 m2 of storage space and technical facilities here. Pipelines are one of the things produced In this yard, which has a production hall, a number of offices, toilets and a canteen with kitchen facilities. There is substantial poverty in the Porto Amboim region and living conditions are poor with, for instance, open sewers and a lack of sanitation and safe drinking water. As one of the major employers in the area, Heerema invests in the local community in various ways. Furthermore, Heerema is committed to social responsibility and health, safety and the environment in the workplace.

PureBlue delivered a decentralised biological water treatment plant to Heerema Porto Amboim in 2010. The package plant was fully assembled in the Netherlands and transported by ship to Angola. The unit purifies the wastewater from toilets, showers and the kitchen. The effluent quality meets European standards. The treated effluent is reused as rinsing water in the toilets. Besides wastewater purification, sludge drying beds have been built that are used by employees to grow papayas and tomatoes. The crops flourish due to the nutrients from the sludge and to being watered with the effluent water. PureBlue provided workers with on-site training on the technical and technological operation of the wastewater treatment plant.
