Innovative Strategies for "One Water" Management: Enhancing Efficiency and Sustainability

"One Water" management is crucial for maximizing resource efficiency and improving planning through a holistic approach to managing stormwater, wastewater, and drinking water. It emphasizes focusing on local water supplies, and integrating energy and water utilities. Key discussions include the challenges of conservation under current rate structures, climate change adaptation technologies, and the necessity of green infrastructure for stormwater management. Collaborative efforts by organizations such as the Water Environment Research Foundation aim to address institutional barriers, promote cost-effective solutions, and communicate effectively with stakeholders.

Presentation Transcript

  1. “One Water” Management Currently very siloed - capture efficiencies, improve planning, & save money Waste water Storm water Drinking water

  2. “One Water” Management Currently very siloed - capture efficiencies, improve planning, & save money Groundwater recharge with recycled water Wastewater reuse Stormwater capture & reuse Nutrient recovery from the waste stream

  3. Other hot topics • Investments in “local” water supplies (as opposed to sourcing them from long distances, as L.A. does) • Recovery of energy/water/nutrients from the waste stream • Greater interaction between water and energy utilities (water utilities generate waste water for cooling that energy utilities need, while energy utilities could be helping to power/heat water facilities). • Difficulty pursuing conservation, as existing rate structures often mean lower water use => lower revenues.

  4. The Box Us Investments in watershed services

  5. “Green infrastructure is just for stormwater.” “Watershed planning is more of a stormwater issue.” “Drinking water protection isn’t really possible any more in most places.”

  6. One water company’s views on climate change “Our priorities regarding climate change are • Harden systems via relocation and barriers against disasters; • Build supply flexibility in terms of increased storage; and • Tech-based adaptation (GPS markers on infrastructure like pipes was the example provided).”

  7. The Utility Perspective • Thinking about stormwater regulatory requirements • Weather volatility • Efficiency and conservation …lots of risk aversion

  8. “I think people are willing to think about green infrastructure for stormwater because stormwater is a ‘new’ problem and so there aren’t really many firmly entrenched solutions. It’s also relatively low-cost and scalable, so it’s more feasible to demonstrate.”

  9. Next steps? • Water Environment Research Foundation, the Water Environment Foundation, and the Center for Neighborhood Technology convening a working group on institutional barriers to ‘One Water’ including economic/financial barriers • Engineers were very interested in our cost-curve work and the green infrastructure database – appetite for cost and performance data and tools to better understand ROI on green infrastructure • Communication and language to the “One Water” audience
