Water and Wastewater Engineering Services Designed for Reliability and Constructabilty
Reliable Water and Wastewater Infrastructure Engineered for Long-Term Performance

Water and Wastewater Systems That Work
Windsor provides water and wastewater engineering services for municipalities and public agencies responsible for protecting public health and maintaining essential infrastructure. From treatment improvements and pump stations to utility upgrades and system planning, we design solutions that function reliably under real-world conditions specific to your site.
How We Work
Understand System Operations:
We meet with owners and operators to define performance goals, regulatory requirements, site constraints, and operational priorities.
Validate Assumptions Early:
We confirm constructability, phasing, and cost considerations, engaging contractors when appropriate to reduce downstream risk.
Coordinate and Document Clearly:
We integrate civil, structural, I&C, and mechanical considerations early and maintain rigorous QA/QC review.
Stay Engaged Through Construction:
We remain responsive during construction to resolve field issues, clarify intent, and protect long-term system performance.
Our Services
Water & Wastewater system Planning & Master Planning
We support system planning and master planning efforts that align long-term infrastructure needs with phased, buildable implementation.
Pipeline, Pump Station, & Treatment Facility Design
We design pipelines, pump stations, and treatment facilities that are durable, maintainable, and aligned with long-term operational performance.
Wastewater Collection & Conveyance System Improvements
We improve collection and conveyance systems to increase capacity, reduce risk, and support reliable system performance.
Stormwater & Wastewater System Integration
We design integrated systems that coordinate stormwater and wastewater infrastructure to improve performance and reduce system strain.
Regulatory Permitting & Environmental Compliance
We coordinate with regulatory agencies to support clear permitting pathways and maintain compliance throughout project delivery.
Infrastructure Funding Strategy & Grant Support
We support funding strategies and grant applications to help advance infrastructure projects from planning through implementation.
Construction Administration & Engineering During Construction
We support construction with field coordination and engineering oversight to ensure systems are built as intended.
Design-Build Delivery for Water & Wastewater Infrastructure
We support design-build delivery by coordinating closely with partners to align design, schedule, and construction outcomes.
