More and more municipalities must consider the impacts of evolving climate conditions to prevent catastrophic damage to water and wastewater infrastructure. Others must alter or diversify operating protocols to maintain service under threat of drought or other extreme conditions. Hazen and Sawyer has helped many municipalities identify and prepare for a range of possible climate conditions and develop cost-effective strategies for protecting public health and the environment.
New York City commissioned a study from Hazen and Sawyer to identify and quantify the impacts of increased precipitation, sea level rise, storm surge, and temperature on the City’s wastewater collection and treatment systems. The study produced valuable vulnerability and
adaptation data that has since been used to revise the City’s design guidelines, emergency action plans, and capital improvement projects.
Hazen and Sawyer conducted an analytical study to determine the potential effects of sea level rise and storm surge impacts at Miami-Dade Water and Sewer wastewater treatment facilities. Adaptation strategies were also considered for all of the wastewater
We performed a comprehensive analysis of demand patterns for the City of Phoenix (AZ), which identified key influences on long-term water efficiency and the conservation potential that could be
realized under acute water shortage conditions in order to improve the City’s long-term planning policies.
Utility owners in South Florida are
now actively mandating hurricane
resistance to be designed into their
treatment facilities. Hazen and Sawyer has assisted several municipalities in designing and constructing better hurricane resistant treatment facilities.
Hazen and Sawyer led an extensive analysis of alternatives for expanding Raleigh’s water supply for future growth and increased resilience to climate variability. The project revealed that reallocation of existing regional storage could provide needed supply, while avoiding construction of a new reservoir.
Hazen and Sawyer can provide a full range of services including planning studies, design, and construction and program management to assist communities with climate adaptation solutions. If it is determined that new facilities are needed, we can also design and oversee construction of dykes and levees, green infrastructure, water supply infrastructure, water reuse/reclamation facilities, and/or desalination facilities.
Whether you need to combat the effects of sea level rise and flooding in a coastal community, address decreased supply of clean drinking water from drought or turbidity events, or protect infrastructure and the environment during large precipitation events through stormwater and wastewater management, we can help.
