On-Demand Training:
Fundamentals of Water Recycling

Recorded: March 1 - 2, 2023

Print

Available water supplies have not been able to keep up with population growth in many parts of the southwest United States. Reclaiming and recycling wastewater has been one response over the past half dozen decades in these areas, along with other parts of the world that share a similar climate, like Spain, Australia, and Israel. However, global climate change has broadened the need to develop this resource to other parts of the U.S., even in states that have historically not experienced water shortages.

Fundamentals of Water Recycling will cover the basics of the entire “water recycling” process, from wastewater collection and treatment to distribution of the product water to end-use. The course will focus on municipal recycled water programs, rather than individual industrial on-site reuse or single-family home “graywater” systems. Attendees will be exposed to water quality and availability considerations, distribution system development, reuse site requirements and best management practices, and customer relations, finishing up with a discussion of potential problems with developing a recycled water program and previously successful strategies and solutions.

Learning Outcomes

Upon completion of this course, participants will be able to successfully:

  • Identify the water recycling process from treatment to end-use
  • Determine the need/viability of recycled water in their local area
  • Evaluate recycled water quality for applications in their local area
  • Determine the social, economic, and environment benefits to their local area
  • Review the initial layout of a recycled water distribution system
  • Identify and mitigate potential reuse site compliance issues
  • Perform a cross-connection site test and ensure backflow is prevented
  • Discuss and address the potential customer issues that might arise
  • Identify physical, regulatory, institution, economic and public acceptance issues and apply appropriate solutions
  • Gain an overall assessment of the entire process to be able to adequately communicate to various project stakeholders

Instructor

Referred to by many of his water recycling colleagues as the “Guru,” Earle Hartling has dedicated his entire professional career to the advancement of water reuse, not only for his agency but for the industry in general. He has been involved in just about every facet of water reuse, including planning and feasibility, regulatory development and compliance, legislation, contracts, external funding, report production, and on-site supervisor training. Since taking over the Sanitation Districts’ water recycling program in 1981, the number of that agency’s reuse sites has increased from 11 to over 900 and the volume of recycled water usage from 35,000 acre-feet a year to over 100,000, just about 75% of the available supply. The amount of revenue generated by this program has increased to nearly $8 million per year, with an additional cost recovery of over $1.6 million per year.
