Sustainable Water Solution

A new sustainable source of water, beneficial to the water-stressed Flemish Region, in line with the Blue Deal

Project Overview

Proposed Dockwater Desalination Plant

  • Project to produce fit-for-purpose process water and demineralized water
  • New sustainable source of water, beneficial to water-stressed Flemish region, in line with the Blue Deal
  • New process water distribution network, increasing supply reliability at the Port of Antwerp
  • Dockwater reduces the environmental impact of the Port, offers customers a long-term supply of lower-cost water, and improves the availability of drinking water in the community
  • Project enhances the competitiveness of the Flemish region

Environmental Benefits

Dockwater will produce fit-for-purpose process water at a centrally located facility in the Port of Antwerp

Local source of process water which:
  1. Decreases industrial customers drinking water consumption by 98%
  2. Decreases aggregate water consumption by 14%
  3. Decreases water treatment chemicals by 70%

Dockwater is a new source of water, which will reduce freshwater stress in the Flemish region, creating water independence. Dockwater will also use 100% renewable energy.

Once up and running, Dockwater intends to work with industrial customers and make use of their effluent wastewater as Dockwater’s source water, closing the loop and creating a circular water economy.

Environmental Impact

Dockwater significantly lowers the environmental footprint of industrial activity

For a typical Dockwater industrial customer, improved water quality will reduce the environmental footprint of their operations:
  • Drinking water consumption reduced by 98%
  • Chemical footprint will be reduced by 70%
  • Operating costs for cooling towers reduced by more than 25%

Through higher quality process water, aggregate water consumption in the port will decrease by up to 3.7 m3 per annum, or the equivalent to the consumption of 80,000 residents.

Drinking Water Consumption (m3/h)
3,000 60 98% Reduction Drinking Water Dockwater
Chemical Consumption (ton/yr)
788 225 71% Reduction Drinking Water Dockwater

Six Tenets of the Blue Deal

The Blue Deal calls for increasing the security of the water supply through off-grid solutions and creating an innovative, circular water economy that reduces aggregate consumption, which Dockwater addresses.

Public administrations lead by example and ensure appropriate regulation

In order to structurally combat water scarcity, we need to intervene on the causes: we need to reduce water flow to our environment by reducing the need for surface water and groundwater.

Raising awareness and encouraging individuals to infiltrate (rain) water

With “Operation Breaking Stone,” the Blue Deal seeks to raise awareness how every square metre of stone replaced by green today helps. Further, the Blue Deal will push for regulation to reduces additional pavement and encourages the planting of tress and water-permeable green areas.

Increasing security of supply

Launch projects to increase both the availability of water for the drinking water supply and to expand the production capacity of the drinking water itself. Protect existing sources of water.

Circular water use as a rule

We need to prioritise "water saving", limiting water demand as much as possible; the cheapest water ultimately remains the water you don't need, and develop tariff structures that encourage rather than inhibit users from investing in reuse and "off-grid" concepts with a guarantee that access to the network remains possible when necessary

Investing together in innovation

Make our water system smarter, more robust and more sustainable through technological innovation, awareness, and incentive programs.

Agriculture and nature as part of the solution

The measure with the highest impact, experts say, is to hold back the water for longer and allow more to infiltrate. This principle has already been included in the coalition agreement. An increased use of water conservation in the open space is an important measure to prevent dehydration and replenish groundwater resources.

Value Proposition

To the Port and the Region
  • The Port of Antwerp represents 8,3% of Flanders’ GDP and is key for the local economy
  • Dockwater provides the best long-term solution to water independence at the Port of Antwerp
  • Dockwater will increase the competitiveness of the Port and the local economy
To the Residents
  • Dockwater will increase the availability of drinking water
  • Dockwater will avoid drinking water consumption corresponding to the daily consumption of over 500,000 people
To our Customers at the Port
  • Dockwater will provide high quality and high reliability process water, which itself will lead to operational benefits that save the environment and money
  • Through an “off the drinking water grid” solution, Dockwater will ensure the Port of Antwerp has continuous access to water supply amid changing regulation of drinking water supply
