This holiday season don’t let fats, oils, and grease (F.O.G) sneak down your sink!

Holiday favorites like turkey drippings, bacon grease, melted butter, and leftover frying oil belong in the trash and not the pipes.

Please dispose of F.O.G properly to help protect our environment and waterways.

In observance of the holidays, our Administration Office will be closed on December 25 and January 1.

Happy Holidays from all of us at CMSA!

We’re hiring!

Our pilot project with Beyond the Dome (BTD) is well underway!

BTD's technology uses an Ultra-Super Critical Water Oxidation process to break down organic materials to produce water, electricity, minerals, and carbon dioxide gas.

The pilot system operates under high pressure and temperature, and is located in a storage container between our solids handling building and digesters. During the pilot test period, CMSA will provide power, recycled water, and dewatered biosolids to the BTD equipment.

The Primary Clarifier and Chlorine Contact Tank Coating and Concrete Rehabilitation Project is complete!

The Project's scope of work included blasting and recoating steel launder mechanisms, resurfacing and coating deteriorated sludge hopper concrete, repairing deteriorated concrete surfaces, replacing failing coatings, and applying new waterproof deck coating to prevent water intrusion.

Congratulations to our very own Bob Stiles, who was just promoted to Lead Mechanical Technician!
