In the early 2000’s, two Orange County agencies faced some challenges. The Orange County Sanitation District (OCSD) needed to replace on ocean outfall for treated sewer water that would cost millions of dollars.
Brown Bag Seminar Series
Bring your lunch and join us for a range of presentations on water-related topics of interest.
Access to the WRRC’s Brown Bag series now routinely includes offsite listeners through live webcasts via Goto-Webinar and in-house video coverage.
The slide presentations of most seminars are also available for viewing on the website.
The Sonoma County Water Agency, located in California about forty miles north of the Golden Gate Bridge, supplies drinking water to 600,000 residents in Sonoma and Marin Counties and provides wastewater and flood control services.
In early November, Tucson Water unveiled a plan that could bring life back to the long-dry stretch of the Sana Cruz River through downtown Tucson. Taking advantage of reclaimed effluent, effluent that now is sent downriver far from the City, Tucson Water hopes to return flow to the river within two years.
Science can be thought of in two mutually incompatible ways: (1) science-as-knowledge, serving as an authoritative basis for action, and (2) sciences-as-process of inquiry, serving as a continually updated guide to action. There is mounting evidence that overemphasis on (1) is increasingly contributing to failures for the betterment of humankind.
Low-Impact Development is a concept that began in Prince George's County, Maryland in 1990, as a practical alternative to traditional stormwater management practices. Low-Impact Development (LID) includes a series of land engineering and development features that minimize infrastructure, control stormwater runoff near its origin, and help recharge aquifers, watersheds, and other groundwater sources; in addition to playing an important role in Smart Growth, Green Building, and helping with compliance of the Clean Water Act.
Ensuring that a readily available supply of water that has an acceptable quality for health, livelihoods, and production continues to be a challenge across the world. This challenge is made greater by increasing demands on water supply, increasing variability in water supplies due to climatic change, and increasing construction of large-scale water infrastructure. Political boundaries crossing watersheds further complicates matters.
Given the many pressures on food, energy, and water (FEW) systems, it is essential that strategies for development and sustainability recognize the inter-dependencies among them. Interactions between FEW sectors and secondary effects of some decisions complicates planning on local and regional scales. Quantitative support to inform decision making is invaluable to provide supporting knowledge/information to expose benefits and costs of infrastructure development and policy implementation for Arizona's FEW systems.
To meet the needs of the greater Tucson metropolitan area, Tucson Water is exploring potable reuse as a means to diversify and expand their water portfolio. To this end, a six-month pilot test of an innovative and sustainable potable reuse treatment scheme was conducted under a tailored collaboration project between CH2M, Tucson Water, and University of Arizona.
Speakers: Beth Kleiman will present, "The Water-Energy Nexus Dimension of the Central Arizona Project System Use Agreement" and Surabhi Karamelbar will present, "When the Turbines Stop Turning: Examining the Impacts of Drought on Power Production at Hoover Dam and Its Consequences for Entities in Arizona"
