Engineers examine drinking water management strategies: Climate change, economic sustainability can impact water distribution systems Sustainability

While residents in California are still dealing with damage from last month’s floods — after years of devastating droughts — UBC Okanagan engineers are looking at better ways to manage the delivery of safe drinking water to homes.

Things to consider include a changing climate, costs and sustainability.

Dr. Haroon Mian, a Postdoctoral Research Associate with UBCO’s School of Engineering, says municipalities and water utilities all have drinking water management strategies to ensure the water they provide is safe and plentiful. However, a natural disaster, a breach in the supply or contamination at the treatment plant can put water supplies — and human health — at risk.

“Freshwater is essential to sustain ecosystem health and our survival,” says Dr. Mian. “But Earth’s once plentiful freshwater resources are now under increasing pressure due to population growth, urbanization and climate change.”

As water supplies become more threatened, not only is providing safe water a priority, but suppliers must also ensure that doing so will have low environmental and economic implications.

“The quality of drinking water is contingent on several important attributes such as water extraction, treatment, delivery, cost and the disposal of used water,” says Dr. Mian who conducts research in UBC’s Life Cycle Management Lab. “Those factors can all be impacted by climate change. And they have a significant environmental influence in terms of natural resource depletion, waste generation and greenhouse gas emissions.”

Dr. Mian and his fellow researchers have developed an integrated assessment framework that combines water quality with lifecycle assessment techniques. Working with data from small and medium-sized communities, they provided a way to assess the long-term applicability of water systems that can provide safe drinking water to people.

According to Dr. Mian, the framework provides a different lens into a more holistic view of drinking water management and its components.

“We measure factors such as water quality, changes to the environment and potential costs to determine performance data and benchmarking, thereby providing important tools to ensure these systems experience long-term effectiveness and sustainability,” he adds.

By considering these key factors, water can flow to a community at a reasonable cost while conserving natural resources and …
