The electricity, gas, telecom and water companies are facing a big challenge. The markets in which they operate are slowly completely opened up for competition. Within this context, Grontmij offers specific solutions to local development agencies, energy suppliers and telecom companies.

Purification techniques for adequate process water and good drinking water
For the production of drinking-water, the choice of source, optimisation and reuse are key issues, for both now and the future. It requires a constant evaluation of cost and sustainability. For water companies, it is a continuous challenge to produce high-quality drinking water. After all, ground water and surface water, the raw materials for drinking water, are increasingly threatened by medicine residues and other toxins. Improved purification techniques are required to meet the demand for good drinking water.

Grontmij has many years of experience with regards to process technology, design and policy. We offer water companies a multitude of experience and techniques, including oxidation by means of UV radiation and hydrogen peroxide, and improved membrane techniques.

Sustainable energy generation
Sustainable energy is energy that is not at the expense of natural resources or of the global food production. Sustainable energy is unlimited energy. Important types of sustainable energy are bio-energy, wind energy, solar energy and heat-cold storage. For example, Grontmij advises on creating small-scale and large-scale wind farms and we are involved in the licensing. In addition, our experts realise projects of biogas valorisation, energy recuperation from waste geothermic installations and heat networks. Grontmij advises on the economic feasibility and other factors that impact the success of a project. In doing so, we pay a lot of attention to the public support and understanding of the project with local residents and decision makers.
