MSc thesis subject: Spatial mapping of (domestic) wastewater availability for re-use

Currently, there is much interest in sustainable resource management. An important aspect of this management is to investigate the possibilities to exchange resource flows, such as water, nutrients or materials, between users. In many cases outflow resource streams of one user can be re-used by other users to reduce the total amount of resources needed. The eco-industrial park of Kalundborg is an example of resource exchange at an industrial scale. At Kalundborg the excess heat of a power plant is used to heat homes and a fish farm.

In order to re-use resource flows, one must analyse and match the demand and supply of resources. To that end, detailed information is required about quantity, quality, time, and location of these resources. GIS tools can be of great help for this analysis when investigating the availability of resources over larger areas.

In the Water Nexus project (see http://www.waternexus.nl) we work on a specific case to match the demand of water for industrial facilities with the local supply in the region of Zeeland. DowDupont is a large chemical company which uses 16 million m3 of water per year. Currently the water comes from Belgium, the Biesbosch, and from the waste water treatment plant of Terneuzen. DowDupont wants to source more of its water locally and is therefore searching for alternative supply sources. In this MSc thesis we investigate the local availability of (domestic) wastewater which could be used as a supply source after (limited) treatment.

Objectives

The goal of this MSc thesis is to:

  • Develop a model/methodology to analyse and map the availability of domestic wastewater streams for industrial reuse
  • Quantify the supply of resource flows (waste water)
    Develop a widely applicable model (not limited to the Zeeland case)
  • Optionally calibrate and validate this model

Requirements

  • For this thesis we are looking for a student with a background in GIS, and who wants to apply his/hers knowledge and skills to sustainable resource management. The thesis will be supervised by two groups: Environmental Technology and Laboratory of Geo-information Science and Remote Sensing.
