A recent study by University of Waterloo researchers highlights the environmental benefits of a $450 million wastewater treatment upgrade in the Region of Waterloo, Ontario. By analyzing more than a decade of data, scientists discovered that aquatic ecosystems in the Grand River downstream from the Kitchener and Waterloo facilities have grown increasingly similar to the healthier upstream environments. These infrastructure improvements, which introduced fully nitrifying activated sludge systems, successfully slashed the amount of ammonia discharged back into the waterway.
To measure the river's recovery, the research team focused on benthic macroinvertebrates — tiny, pollution-sensitive animals that live on the riverbed and form the foundation of the aquatic food web. Researchers emphasized that a rigorous monitoring program initiated in 2009 was vital for tracking these changes.
Hawaii Water to Study Reuse Plant Feasibility in Kapalua
Hawaii Water Service has selected Carollo Engineers to conduct a feasibility study for a new decentralized wastewater treatment plant in Kapalua. Currently, the area's wastewater is transported through the Hawaii Water system and treated at the County of Maui’s Lahaina Wastewater Reclamation Facility. If constructed, the new decentralized plant would produce recycled water, providing the community with a valuable, drought-resistant supply for irrigation.
The study is expected to be completed in the fall of 2026. It will identify potential sites for the facility and evaluate advanced treatment technologies to improve efficiency, while also analyzing regulatory requirements, land needs and projected operations and maintenance costs.
Amazon Plans $12 Billion Data Center Investment in Louisiana
Amazon has announced plans to invest $12 billion to construct new data centers in northwest Louisiana. Amazon expects the buildout to create 540 full-time positions, along with additional support roles for electricians and HVAC technicians.
While data center developments often face community pushback due to massive water requirements, Amazon has pledged to mitigate the environmental impacts. The company says it will establish a $400 million fund dedicated to the area's water infrastructure and stated that its water usage will be restricted to cooling and other essential needs.
