Water Supply Engineering | Wastewater Treatment

Approximately 87% of Americans receive their potable water from a public water system. Any design or upgrade of these critical systems requires a wide range of engineering disciplines. Aquarion has planned, designed, and implemented numerous water projects, including:

• water system feasibility studies and assessments
• water system and water main design
• process and treatment system design
• pump or booster station design.

Aquarion is a top choice for specialized water engineering services such as potable water system analyses (including SDWA impact studies), corrosion control assessments, user fee studies, and privatization studies.

Aquarion serves industries, municipalities, government agencies and private organizations in New England and throughout the United States. We also provide international environmental consulting services regarding the evaluation of existing water treatment facilities.

Water Supply Engineering Case Studies
Comprehensive System Facilities Plan—Friendship, Maine
When petroleum hydrocarbon contamination was detected in a local aquifer, Aquarion Engineering Services was contracted by the Town of Friendship to complete a Comprehensive Facilities Plan for the Friendship Community Water System. Our plan allowed an increased in the pumping rate from the well without drawing in a contaminant plume or salt water located nearby. In addition, Aquarion designed backup power for the station, assessed the impact of the Safe Drinking Water Act, and modified the system’s wellhead protection zone.
Vulnerability Assessments—New Hampshire, Massachusetts, and Connecticut
Aquarion completed six vulnerability assessments (VAS) for water systems located in New Hampshire, Massachusetts, and Connecticut. We applied the Risk Assessment Methodology for Water Systems (RAM-W) that was developed by Sandia National Labs. The medium-sized water systems being studied serve populations ranging from 7,400 to 20,900 people.
  
Water Intake Structure Modifications—Lebanon, New Hampshire
The infiltration galleries of the Lebanon water treatment facility were frequently fouling due to silt deposition in the Mascoma River and the majority of flow was entering through the auxiliary intake screen. Aquarion identified the auxiliary intake as a hydraulic limitation of the treatment facility by performing a hydraulic analysis and developing a hydraulic model of the treatment plant.

To remedy the faulty treatment facility, Aquarion engineers designed several modifications to the water intake structure that ultimately increased flow capacity through the facility. The modifications included an additional auxiliary intake, upgrading screens to reduce icing in the winter, and the installation of a water level telemetry system to monitor headloss from the river. Construction of this upgrade was completed in September 2000.
