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.
Disruptive and game-changing approaches are needed to allow today’s wastewater treatment plant to evolve as a water resource recovery facility (WRRF) of the future. During a workshop at WEFTEC on Saturday, Samuel Jeyanayagam will explore the many uses of carbon at a WRRF including production of energy, volatile fatty acids for nutrient removal, and marketable chemicals.
Today, CH2M is proud to join elected officials, drinking water and wastewater providers, community leaders, business and labor groups, policy experts, advocacy organizations and infrastructure experts for Imagine a Day Without Water, a day specifically designated to educate the public about the water infrastructure crisis currently facing the United States.
CH2M's Mike Matichich and Mark Mittag discuss how collaborative funding builds new economic opportunities for the city of Detroit. The Detroit Future City Strategic Framework, highlighted in their blog, is an ambitious initiative aimed at creating vibrant, open spaces and thriving neighborhoods throughout the city of Detroit.

A Flight Simulator for Treatment Facilities: The New Frontier for Modelling Complete Treatment Plant Operations
Jason Curl, CH2M's Global Service Team Leader, Software Applications and Integration, and Matt Deavenport, CH2M's Global Technology Leader for Dynamic Simulation, talk about dynamic simulation software, which leverages powerful computational capabilities and is founded on industry standard hydraulics, controls and water quality calculations. Dynamic simulation software can be used to help mitigate and manage challenges with water conveyance and treatment infrastructure. In today's blog, Jason and Matt highlight CH2M’s Replica™ software, one tool that can be utilized to evaluate the abundant operational data that exists and fully understand the changing water quality, hydraulics and controls in an operational facility.
