Portland’s Approach to Rehabilitation of a 100-yr-old Brick Outfall

Centralized collection—using large diameter interceptors, trunk lines and transfer sewers—has frequently been the backbone of a wastewater collection system for centuries. In the United States, many large diameter sewers have been in service well past their design life, and consequently, we’re seeing more headlines in the local newspapers of sinkholes, pipe collapses and overflows taking place when these aging sewer systems fail. CH2Mer Daniel Buonadonna shared a case study on the City of Portland's strategy for rehabilitating one of its oldest brick sewers at the Water Environment Federation's Technical Exhibition and Conference (WEFTEC) this week.

Global Experience with Coastal Resilience

Coastal communities are facing unprecedented challenges as populations continue to increase at unprecedented rates, and more people are moving to coastal cities. Today, according to the United Nations, more than half the world’s population live in coastal zones and three quarters of large cities are on the coast. With present day flooding and coastal erosion hazards set to be exacerbated by future climate change, the risks facing coastal populations and infrastructure will increase. Aging flood and coastal protection infrastructure is further exacerbating these challenges, as structures reach the end of their useful life, and no longer offer the standard of protection they are designed for. In today's Access Water blog, CH2M Global Technology Leader for Water Resources and Ecosystem Management Adam Hosking highlights these trends taking shape in coastal communities and discusses our integrated approach to implementing multi-dimensional coastal resilience solutions to protect people and property in coastal communities around the world.

New Guide Available to Help Water Utilities Handle Drought

Extreme weather events can wreak havoc on utilities. Whether getting too much water at once, resulting in floods, or not getting enough, resulting in drought, the availability of water is unpredictable at times. Therefore, making sure utilities are prepared is the first step to managing these situations. Check out today's Access Water blog to learn more about a Drought Response and Recovery Guide for Water Utilities, produced by the U.S. Environmental Protection Agency. The Guide provides worksheets, best practices, videos and key resources for responding to drought emergencies and building long-term resilience.

Investing to make water and wastewater utilities more resilient

Two CH2Mers were featured in the United States Environmental Protection Agency's (EPA) recent video, “Don’t Get Soaked: Invest in Emergency Preparedness, Prevention and Mitigation Activities,” which highlights the benefits of investing in preparedness, response and recovery activities at utilities.

Achieving Excellence in Maintenance, Operations, and Reliability by Implementing Best Practices

Srinivas Jalla, along with other CH2Mers, will be attending and presenting on best practices in asset management and more, at the 2016 Utility Management Conference, being held in San Diego, California, February 24-27. Over the last eight years, Gwinnett County Department of Water Resources, in Atlanta, Georgia, USA, has worked to improve maintenance and reliability and is leading the way for other utilities. Check out today's Access Water blog to learn more about Gwinnett County's MORE (Maintenance, Operations, and Reliability Excellence) program.
