Graduation day at Summer School

August 23 marked the end of two intensive weeks of learning, networking and having fun for our course students, who has left Låsby with their diplomas in hand, ready to go influence the future water industry. 27-08-2019

By 3PM on August 22nd, the students of our Advanced Water Cycle Management Course had submitted their concluding work at Aarhus University’s web portal. The following afternoon, they finally presented their solutions to a small committee.

At the finish line, the mix of guiding theory backed by semi-practical tasks has proven a very successful way of planning a summer school – both for the students and for the Danish companies involved.

Moving away from “silo mentality”

Half-way, the course was divided onto three thematic tracks of Groundwater, Water Distribution and Wastewater. When the students were handed their task, which was specific to the track they had chosen, it was no prerequisite that the groups should consult with each other across the tracks. However, in line with the course concept of thinking sustainability into every single step, it came natural to the groups to make sure that their solution was actually feasible, and that all points in the chain were considered. Some did so by scheduling project meetings with other groups, to collect and highlight the most important knowledge. As one of the students explain:

“Our task is specific to groundwater, but if we are to think about implementing a specific solution, we cannot just plan to drill wells here and here, and pump up this much water; the water will have to be distributed, so we also need to know what the customer demands are, and so on. We need to know the full circle.” – Shane Carrohan, Ph.D. student at DTU Miljø.

Turning waste streams into value streams

This way of considering the ‘full circle’ also included to rethink the whole collaboration of industries in an area, to make sure that processes are built and optimised in the most sustainable way. As an example, one of the groups presented a ‘Future Industrial symbiosis’, where a wastewater treatment plant was analysed in relation to the local farming and tanning industries, and the multiple ways they can benefit from each other.

Smart water usage and data based decisions

Another group considered the issue of flodding vs water scarcity. To avoid flodding, rain water can be collected through infiltration ditches and stored in a retention basin, ready for use in periods of water scarcity. Additionally, by the use of a run-off river hydropower plant, the water can generate electricity for the pump that will, later on, carry it to where it can be used. To optimise water management, the group divided their city into district metering areas. This way, they were able to manage pressure within the water network, and to obtain a leakage detection program. This allowed them to reduce lost revenue by 64 %, covering a 13 % cut in water losses and almost a 50 % cut in average water pressure

Focused efforts and important field insight

This knowledge-sharing across different topics within the water sector, and the introduction to so many of the big Danish companies involved is mentioned as one of the main reasons to joining the course. Also, Shane mentions the unique location in Låsby; a small town in cosy and beautiful settings, but with limited entertainment within short reach. This offered great opportunities to socialise and network, and there was no time wasted on transport. A good match, as the course plan was very intensive, so this allowed the students to stay within this ‘bubble’ of learning.

Shane, who found the course while searching online, describes how he chose the course as it was the only available which included multiple fields, it was a complete ‘package’ including housing, transport etc., and further explains: “I would recommend it based on the course content, whether or not you are already experienced within the specific field of choice, but also because you get practical experience including introduction and training in i.e. relevant software programmes.”

Learning from each other

The students arrived from all parts of the world, which brought a lot of value to the knowledge sharing process. According to Shane, the different cultural backgrounds were a huge gain to the group work, and contributed with so many views in both the product and solution selection, which otherwise would have been missed; such as considerations about specific environmental settings, protection against theft of products, and so on. This also emphases the fact that the companies involved are also gaining a lot from a course like this, where their solutions and products are viewed and analysed from multiple angles. Friday night, the committee awarded prizes for the most innovative idea, the best teamwork and the best overall proposal to the tasks given.

Teaming up for future water solutions

The second week of our Summer School 2019 has been kicked off, and students are now putting their new water skills to the test.
