IWA World Water Congress - Glasgow 2026 - Meeting the World!

Marsh Industries Ltd have been exhibiting and taking part in the wider workshops, forums and seminars at the IWA World Water Congress in Glasgow, Scotland.

Proceedings began on the Sunday with an Opening Ceremony at the SEC Armadillo. A thought provoking keynote speech “Respecting the Role of Water in the Earth System” delivered by 𝐏𝐫𝐨𝐟𝐞𝐬𝐬𝐨𝐫 𝐊𝐚𝐭𝐡𝐞𝐫𝐢𝐧𝐞 𝐑𝐢𝐜𝐡𝐚𝐫𝐝𝐬𝐨𝐧 of the University of Copenhagen, Denmark. Recognising the importance of water and its interconnectedness with the wider environment and our shared future.

The ribbon was then cut open to unveil the exhibition hall and give Michael Harrison, Stuart Thompson and Mark Bishop of Marsh Industries their first opportunity to meet with the ~7,000 delegates and visitors attending the IWA over the 5 day duration of the congress.

Over the course of the week we met with visitors from all corners off the world. From Greenland at the top through the Americas, Africa, Australasia, Europe and Asia. All with a common desire to do the right thing in their home location for the betterment of the environment.

Our thanks go to the Foreign, Commonwealth & Development Office (FCDO) for bringing an Indian delegation to meet the team on the stand and explore opportunities for off-mains drainage. We were supported by Dharmendra Nayee from our partner DND Construction Technicals in the UAE in this activity. Helping to quickly identify next steps for progression.

With the biannual global event taking place in Glasgow, it also gave an opportunity to catch up in person with many of our UK contacts and discuss ways in which we can work together.

Seminars and Workshops

Outside of the main exhibition hall, a daily programme of seminars, workshops and forums took place centring around the core six themes of the congress.

This provided an opportunity to continue to support the pressing issue of delivering Rainwater Management solutions in the UK. With sessions titled "From Drain to Gain" and “Managing Rainwater Where it Lands”. With sessions led by George Warren from Anglian Water and Matt Wheeldon of Wessex Water.

Dr. Julia Buckley lent government support to the topic and updated on the aim to make rainwater harvesting and greywater reuse a mainstream requirement in UK buildings, particularly new developments, rather than leaving adoption entirely voluntary. A significant case study from Belgium in particular showed what can be achieved. With domestic usage reduced to 80 litres per person per day in the Flanders region by implementing widescale rainwater harvesting. It was good to catch up at the congress with fellow champions of this topic Matt Hull ACIM, Stuart Stevenson and Lutz Johnen.

Whilst the climate is changing in the UK. There is the opportunity to learn from countries that have already encountered these conditions ahead of the UK. The “Millenium Drought” in Australia providing many learnings that can be utilised in the UK. With a multi source strategy being key.

To help bring the level of “energy” required to lift drinking water to a typical toilet cistern the Stoltman Brothers showed what it takes to lift this weight and show how rainwater management can be introduced to remove this requirement.

The Industrial Water forum gave an insight into the direction of travel for the much required need for increased water reuse in these settings. With less than 15% of industrial water being reused. The need to encourage companies to look at water in as a utility spend in the same way Gas and Electricity are considered was also noted. With the “cost of kit” to be considered against an eventual “cost of no water”

Alongside case studies of water reuse and redistribution in Morocco and the potential in Scotland. Looking at sustainable approaches to this topic.

Marsh Industries Ltd broad product range enables us to offer solutions in this field for domestic and commercial sewage treatment, oil water separators, pump chambers, condensate tanks, storage and rain water management.

We look forward to building on the momentum from the IWA Congress to support these key topics.
