Episode notes:

This bonus episode expands on Episode 6 with three facility-level examples of water resilience in practice. While each begins with a different physical risk, all demonstrate the importance of translating climate assessment into engineering, operational, and business continuity decisions.

The first case examines recurring river flooding shaped by reservoir releases, coastal tides, and local topography. C. Rajadurai explains how flood modelling can be overlaid with critical assets to identify vulnerability and recovery time, helping facilities prioritise electrical systems, transformers, and other equipment for elevation, protective walls, or pumping.

The discussion then turns to extreme rainfall and water scarcity. Site-specific stormwater modelling can reveal whether ageing drainage networks remain adequate, while diverting roof runoff to groundwater recharge can reduce flooding without rebuilding the whole system. Diversifying supply through rainwater collection and treated municipal wastewater also reduces reliance on a single groundwater source and strengthens business continuity.

Guest quotes:

C. Rajadurai:

“Source diversification is not only a water management strategy; it is part of business resilience and the business continuity plan.”

C. Rajadurai:

“Climate risk assessment becomes valuable when findings reach engineering drawings and planning teams, translating risk into on-the-ground implementation.”

Episode 6 of Rethinking EHS, Season 3 focuses on water-related infrastructure resilience and how organisations can prepare for more frequent and severe climate-induced water risks.

Across the UK, India and Switzerland, the discussion shows that resilience challenges take different forms — from surface-water and coastal flooding to drought, intense downpours, glacier melt and slope instability. A recurring lesson is that infrastructure can no longer be planned as isolated assets or designed only around historical climate records; connected systems and cascading failures must be considered.

Looking ahead, the guests emphasise proactive, pre-event planning: integrating climate risk assessments into asset management, combining engineered and nature-based solutions, improving forecasting and monitoring, learning across regions, and mapping supply-chain exposure. The goal is not simply to withstand the next event, but to keep essential services operating, recover quickly and remain fit for purpose over the full design life.

Guest quotes:

Alex Perryman:
“So I'd say in the UK we're talking about the whole spectrum, like too much water, too little water and everything in between and the quality of it, the availability of it, how efficiently we use it and how we reuse it even as a resource.”

Michalis Lellis:
“Climate conditions are changing and infrastructure that was once considered resilient may no longer provide the same level of protection in the future.”

This bonus episode expands on the themes discussed in Episode 5 by providing a practical example of how energy resilience strategies are implemented at the local level.

The discussion focuses on Switzerland's requirements for large energy consumers, organisations that exceed defined thresholds for electricity or heat consumption and are therefore subject to specific obligations to improve energy efficiency and reduce emissions. The guests explain the regulatory pathways available, including target agreements, energy audits, and cantonal agreements, highlighting how requirements can vary across Switzerland’s 26 cantons.

Ultimately, the case study reinforces a central theme of the series: global challenges require locally informed solutions, and energy resilience depends on balancing regulatory compliance, operational efficiency, and long-term sustainability goals.

Guest quotes:

Mariarosaria Gagliotti:

“By meeting the definition of a large energy consumer, the company is obligated to take action, implementing reasonable measures to optimise energy consumption.”

Sofiane Kessouar:

“The LEED certification provides a framework for designing, constructing and operating highly efficient and cost-saving green buildings.”
