Risk & Resilience and Emergency Response Requirements for Water Utilities: What does this mean for you?

6-15-2021

The United States Environmental Protection Agency has announced that community water systems that serve more than 3,300 people are required to complete a risk and resilience assessment and develop an emergency response plan by June 30, 2021. (This is according to Section 2013 of America’s Water Infrastructure Act of 2018.) Are you prepared?

What is a Risk and Resilience Assessment?

According to the EPA, risk and resilience assessments “evaluate the vulnerabilities, threats and consequences from potential hazards.” These must be reviewed every five years and resubmitted to the EPA. They include elements such as natural hazards and malevolent acts; resilience of water source treatment, and distribution system infrastructure; monitoring practices; security and resilience of financial, electron...

Part 1: AFT Arrow

By Matt Steiner & Jen Murphy

Many utility ratepayers are currently struggling with economic security. At the same time, energy costs are rising and the impact of uncertain material and equipment markets is driving project costs up and making capital planning less predictable. As such, it is important that as engineers that we leverage all available tools to optimize each project’s capital and operational costs. Almost just as important is sharing what we learn with not only our colleagues, but the wider engineering community.

The Aeration systems at Resource Recovery Facilities (Wastewater Treatment Plants) account for 30 to 80 percent of a plant’s energy usage, making them typically the single largest source of energy use within the facility. They’re also the most complex and capital intensive systems within a plant. This integral system, which ... (more)
