Reliable Wastewater Infrastructure for Growing Communities

LAN designs wastewater treatment plants that balance operational performance, long-term reliability, and future capacity.

Designing Wastewater Facilities That Perform

Wastewater treatment plants must operate reliably for decades while adapting to evolving regulations, population growth, and changing operational needs.

LAN’s wastewater practice brings together process engineers, hydraulic specialists, and infrastructure designers who focus on practical solutions that improve plant performance and long-term system reliability.

Our teams collaborate closely with plant operators and utility staff to ensure designs support efficient operations while minimizing disruptions during construction.

LAN has designed and upgraded treatment facilities ranging from 0.1 million gallons per day (MGD) to 320 MGD, including both new plants and complex rehabilitations.
