Water Supply and Treatment

Water Supply and Treatment

Recognized leadership in safeguarding drinking water supplies and treatment, to keep communities thriving

To sustainably deliver safe and reliable drinking water to its customers, utilities must address a variety of old and new challenges. These challenges include water supplies threatened by over-reliance, contamination, and climate change impacts. Today’s public is more educated on water issues and regulations are getting stricter.

Brown and Caldwell works in partnership with our client to address these challenges by providing industry-leading expertise and vast experience with water supply planning, treatment, storage, transmission, and distribution system design and construction. We excel in identifying, developing, and implementing innovative water management and treatment strategies, from planning through project completion, to deliver solutions in source control, water characterization, process design, pilot testing, optimization, startup/commissioning, and operations training.

Planning and Responding to Wildfire Impacts

The combustion process during fires releases organics, inorganics, and nutrients that were bound in the watershed covering and soil, making them available to mobilize during rain events. During the first few rain events following a fire, extreme turbidity spikes are common. Long term impacts of these changes to the watershed—which can impact water quality for five or more years—are particulates, increases in organics, and nutrient loading. The increase in organics can drive up disinfection byproducts and the nutrients, can lead to harmful algae blooms.

This helpful guide includes helpful steps to plan for the impacts of wildfires on a watershed.
