Water Resources

Our communities face a wide range of water resource challenges that transcend political boundaries and require regional watershed-based solutions with interrelated and integrated holistic approaches. Wright-Pierce provides creative solutions to complex water resource challenges with combined expertise of civil, water, wastewater, stormwater and water quality engineers and hydrologists as well as planning, economic, public participation and decision-making specialists.

Stormwater Improvements
Bristol, Rhode Island

Wright-Pierce’s approach to stormwater improvements at a regional school site considered ease of maintenance and educational opportunities. Stormwater best management practices, including low impact development features, were designed and implemented as part of this project.

Marsh Restoration
Old Orchard Beach, Maine

A flooding assessment identified deterioration of a coastal marsh as a factor, due to reduced tidal flushing resulting in invasive species growth. A strategy was developed for controlling invasive plant growth which included various mitigation measures.

Pond Dredging
Enfield, Connecticut

This project is part of a long-term mitigation strategy to reverse the effects of sedimentation induced by development within the watershed. Elements included coordination with state and federal regulatory agencies for maintenance dredging in support of water quality enhancement.

Bridge Replacement
Harpswell, Maine

Replacement of a coastal short-span bridge to enhance fish passage and increase tidal flushing within an adjacent marsh to inhibit invasive freshwater plant growth. Construction was timed to minimize impact to aquatic species, and traffic was maintained or rerouted until completion.

Reservoir Dam Inspection
Bethel, Connecticut

Connecticut dam safety regulations require owners to have a professional engineer perform inspections. Wright-Pierce works with the Town of Bethel to perform inspections and submit reports to the CT DEEP.

Dam Rehabilitation
Smithfield, Rhode Island

This dam rehabilitation included assessment, design, permitting, and construction administration for repair and replacement of spillways, supports, walkway, and control gates. The project overcame challenges of site constraints, seasonal level variations, and construction sequencing.
