Ingenuity and State-of-the-Art Upgrades Drive Award-Winning Improvements

The City of Concord embarked on a state-of-the-art chemical process upgrade to its water treatment plant (WTP) for improved safety and water quality, as well as greater efficiency. In service since 1974, the Concord WTP, a 10 million gallons per day (MGD ) conventional filtration treatment plant , which treats a New Hampshire surface water supply, was due for an upgrade. Our role was to evaluate its existing chemical feed process, design improvements, and oversee the construction administration of this high profile project.

It’s All About the Process

Recent chemical process improvements at Concord’s Water Treatment Plant (WTP) included replacing aging components to ensure code and safety requirements, providing secondary spill containment, as well as increasing the overall efficiency and modernization of the WTP’s chemical storage system. This included a new chemical room, replacement of bulk storage tanks, as well as installation and startup of a new generator.

Using 3D designs, we engineered the new chemical feed systems to fit perfectly within the footprint of the existing chemical room. This design method was instrumental in driving collaborative conversations, and helping operators to visual the final product. By connecting every phase of the design process through a single 3D digital model, we could test and optimize the final chemical system design. This was critical to driving innovation, achieving a higher quality end product, reducing project duration, and increasing overall client satisfaction.
