Water and wastewater engineering consulting
We combine technical excellence with creative thinking to ensure public safety and uninterrupted water supply operations.
When it comes to the consumption and disposal of public water supplies, ensuring public safety and continuous operations are essential. But achieving these goals efficiently and effectively can seem impossible when challenges — like aging infrastructure, regulatory compliance, climate change, emergency conditions, limited funding, and emerging contaminants — continually appear. You need a water and wastewater engineering partner who can not only quickly step in to address your challenges today, but knows how to plan for future challenges that haven’t yet emerged.
At Haley & Aldrich, our experienced scientists, engineers, construction, and remediation experts combine technical excellence with creative thinking to find the right solution for your water and wastewater engineering challenges. Our heritage of technical excellence and innovation allows us to design an approach at the start of a project that will save costs during construction. Many water and wastewater improvements are sited in poor soils, near waterways and wetlands, and the seasoned geotechnical and environmental engineers at Haley & Aldrich have the expertise to address the most challenging problems with technically sound and practical solutions.
What also sets Haley & Aldrich apart is our ability to look ahead and consider challenges that could emerge down the road. We continually assess potential project risks, and either remove or quickly address them as they are identified. The result? You’re able to efficiently and effectively operate your essential system without disruption.
