Water/Wastewater

Supporting a Wide Range of Projects

Identifying an appropriate and efficient means to maintain and upgrade water and wastewater infrastructure in an environment of constrained budgets, heightened environmental concerns, and ever-increasing regulatory scrutiny is a challenge faced by many utility owners and operators today.

EA has more than three decades of experience providing engineering and compliance management solutions for the full range of infrastructure systems involved in drinking water treatment, storage, and distribution; wastewater collection and treatment; residuals management; and stormwater collection, discharge, and/or treatment. As a result, EA provides expertise in managing the entire project life cycle for these systems, including comprehensive studies and evaluations, design of new and upgraded utilities and facilities, and full-service program and construction management services. Our focus is to identify practical solutions to address system inefficiencies.

Maximizing the Value of Our Water Resources

From the conservation, protection, and management of potable water sources to the evaluation and design of drinking water treatment and distribution systems, EA provides comprehensive consulting services for the water/wastewater industry. To support our clients in their decision-making process regarding system evaluations, operations, and proposed improvements, we draw upon our extensive planning experience developing and implementing distribution system models utilizing a variety of widely accepted applications. Our modeling experience includes evaluating security and system vulnerability, optimizing disinfection contact time, and minimizing disinfectant byproduct formation, in addition to traditional hydraulic modeling for capacity analysis and assessment of water storage.

Managing the Collection and Treatment of Wastewater

EAs broad range of wastewater collection and treatment expertise includes Capacity, Management, Operations, and Maintenance consultation; biological nutrient removal and enhanced nutrient removal processes; and toxicity identification evaluation and toxicity reduction evaluation studies. In addition, we offer extensive regulatory negotiation and environmental compliance experience, as well as an extensive knowledge of the municipal infrastructure planning processes. EA is a proven leader in all aspects of collections systems management, including planning, design, inspection and testing, infiltration and inflow studies, evaluation, rehabilitation, installation, and compliance.
