Our clients are water authorities and water users that realize that effluent re-use is becoming an increasingly important measure to secure business continuity.

Estimated global water infrastructure market size

On a global level, municipalities consume an average of 10% of fresh water, industry consumes an average of 20% of fresh water, and the agrisector consumes an average of 70% of fresh water available. However, with increased industrialization in developing and emerging countries, this balance will likely shift towards an increasing share of the industry’s fresh water consumption.

Governments around the world are developing incentives to encourage municipalities, industry, and the agrisector to maximize water recycling and effluent re-use, in order to meet the growing demands for clean water, and to protect and conserve our natural water sources.

Unique Selling Points

But how best to assess all the available options for water recycling and the cross-sector re-use of effluents? And how best to maximize the quality of the water infrastructure investment decisions? That is where our model comes in. The model takes available water resources and landscape features into account, and matches water supply to water demand from the municipalities, industry, and the agrisector. The model identifies the optimal effluent re-use scheme to meet all demands for water at river basin level. We look at grey and green water treatment, water storage, and water transport solutions.

Key challenges in the development of cross-sector effluent re-use schemes are of technical, economic, relational, organizational, and political nature:

  • Technical challenges
    How to best match the supply of different water sources to the (growing) demand from different water users? And what is the best combination of water treatment technologies to maximize the value of the effluent re-use scheme?
  • Economic challenges
    How best to assess the business case for effluent re-use on system level as opposed to individual technology level? How to ensure CO2 targets are not exceeded? And how to ensure the investment proposition is robust in the face of changing regulations?

  • Relational challenges 
    How to counter inaccurate arguments, or how to address concerns put forward by different stakeholders on the potential risks of effluent re-use? And how to ensure that all stakeholders benefit from the water re-use scheme? How to create win-win solutions?
  • Organizational challenges
    How to support the organization’s longer term vision and growth plans, and how to validate or improve the organization’s existing investment plans ? How to support the organization in the management of in-house business critical knowledge?
  • Political challenges
    How to create constructive dialogue between the public and private sector on the development of water related policies and regulations (e.g. related to wastewater discharge fees or differentiating water pricing systems)?

Our model addresses all of these challenges. Contact us for more information!
