Prestressed Concrete Tank Applications

Oval Wastewater Process Tanks

CROMS’s oval wastewater process tanks feature multiple compartments and robust construction to ensure durability, longevity and optimal performance. Our unique design/build approach covers your entire scope of needs for wastewater infrastructure.

Oxidation Tanks

Oxidation ditch treatment systems typically consist of single or multi-channel configurations with ring, oval, or horseshoe-shaped basins. The structures are designed and constructed in accordance with the applicable portions of AWWA Standard D110 using the Type II wall configuration– shotcrete with an embedded steel diaphragm.

As a result, these tanks are known for their outstanding concrete crack control, watertightness, appearance, longevity and minimal maintenance requirements.

Bionutrient Removal Tanks

Bionutrient Removal Tanks (BNR), designed according to AWWA D110 standards, are typically reinforced concrete tanks with prestressed wire to ensure structural integrity.

These tanks feature multiple compartments to facilitate the sequential removal of nutrients. The robust construction ensures durability, longevity, and optimal performance in wastewater treatment.
