Atmospheric Water Tanks (Underground)

Mass Tank fabricates large capacity steel Underground Atmospheric Water Tanks from 500 to 57,000 gallons. These tanks are fabricated either in our shop or can be field erected. Atmospheric Storage Tanks are commonly used for drinking water, fire protection, agriculture, rain water, leachate, waste water and can also be used for additional materials.

Standard on all Mass Tank manufactured Atmospheric Water Tanks are 24” manways, NPT fittings, NSF 61 interior liner for potable and non- potable water.  Optional, based on the tank size and recommendation of Mass Tank engineers, are nylon hold down straps with turnbuckles.

Mass Tank underground water tanks are also available with FRP exterior clad for additional corrosion protection which extends the Mass Tank warranty for 30 years.
