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.
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.
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.
The City of Omaha is in the process of implementing a $2 billion Long Term Control Plan to control combined sewer overflows (CSOs). While significant portions of the controls are structural, including tunnels, tanks, treatment systems and sewer separation, the City is also including Green Infrastructure projects. Read today's Access Water blog or join CH2Mers Patricia Nelson and Tom Heinemann, along with Jim Theiler with the City, on Wednesday, for an update on the program at this year’s WEFTEC.
