Past Events
Seasonal to Sub-Seasonal (S2S) Precipitation Forecasting
Date: December 5, 2017
Time: 10:00 am - 3:00 pm
Location: Orange County Water District
18700 Ward St, Fountain Valley, CA 92708
What's Important About S2S Forecasting?
There is a recognized need to improve weather forecasting beyond current capabilities. Operational weather models can forecast precipitation events about 2 weeks out, but water managers need more information to make long-term plans for storing and distributing water supply. Precipitation projections for longer time horizons, up to a year, would be of great benefit to water professionals in intensively managed environments such as California and the Western states, where periods of prolonged drought alternate with intense rainfall events. As our capabilities for longer term projections improve, so will the effectivness of strategies to manage water infrastructure including dams, flood storage, and reservoirs.

Workshop on Non-Potable Onsite Water Systems
The Water Environment & Reuse Foundation (WE&RF) and NWRI and partner organizations organized the Workshop on Non-Potable Onsite Water Systems, held November 8, 2017, at TreePeople, in Los Angeles, California. The purpose of the workshop was to engage attendees on the current state and future direction of onsite non-potable water systems. Presentations highlighted findings from the National Blue Ribbon Commission and others. Discussion topics included water quality guidelines, regulations, permitting, treatment system design, economics, operation of onsite systems, and opportunities for centralized utilities.

2017 NWRI Clarke Prize Conference
"Research and Innovations in Urban Water Sustainability"
Date: October 20, 2017
Location: Irvine Marriott, Irvine, CA
The 2017 NWRI Clarke Prize Conference brought together scientists and experts from across the water community to discuss the most innovative research and technology developments happening today in urban water sustainability.
Held on October 20, 2017, in Irvine, California, the conference featured presentations by the NWRI Clarke Prize Laureates, representatives from local water and wastewater utilities, and academics from various universities. The talks focused on managing and advancing sustainable water treatment technologies.
The result was an extended discussion on water resources that included theoretical concepts, basic science research, practical applications, and case studies. The highlight of the event was the Clarke Prize Award Ceremony and Lecture in honor of Charles N. Haas, Ph.D., the LD Betz Professor of Environmental Engineering and Head of the Department of Civil, Architectural, and Environmental Engineering at Drexel University in Philadelphia, Pennsylvania, and the twenty-fourth recipient of the NWRI Athalie Richardson Irvine Clarke Prize for excellence in water research.
Trained in both engineering and microbiology, Haas used his cross-disciplinary education to explore the disinfection and inactivation of pathogens in water since receiving a doctorate in Environmental Engineering from the University of Illinois at Urbana-Champaign in 1978. At that time, public health agencies and regulators did not have a practical or effective scientific method to inform whether treatment processes were adequately eliminating the risk of exposing the public to pathogens in municipal water supplies. They instead relied on limited approaches, such as testing water for indicators of such contamination and/or the absence of reported waterborne disease outbreaks, to determine that water treatment plants were achieving their goals in reducing or eliminating pathogens.
More than 120 people attended the conference, representing universities, consulting firms, government agencies, manufacturing firms, water and wastewater utilities, and others.

Short Course on UV for Wastewater and Water Reuse
Held: March 2008
Location: Orlando, Florida
Partners: International Ultraviolet Association, WateReuse Florida, Carollo Engineers, Black & Veatch
Purpose: To provide the tools and resources needed to help utilities implement cost- and performance-effective UV systems as a reliable treatment technology for waterborne pathogens in wastewater and recycled water.
Brief Summary:
Over 90 participants came together at the UV workshop to learn more about implementing cost- and performance-effective ultraviolet (UV) disinfection systems.
A simple, low-cost, and highly efficient technology, UV disinfection uses high levels of radiation to disinfect water and wastewater, damaging the genetic structure of waterborne pathogens, such as bacteria, viruses, and protozoa, and rendering them non-infectious.
Topics included the following:
- The public health relevance of disinfection.
- Certification processes and certified UV reactors.
- Capital costs and operation costs.
Also featured were manufacturer equipment displays, and the opportunity to join in roundtable discussions about UV technology and the different types of resources and suppliers that were available to support UV systems.
