We manufacture these Frac Water Tanks to the highest standards and build them right here in Canada out of our Medicine Hat, Alberta facility.  We’ve deployed and set up a number of our tanks for clients with oil plays in Saskatchewan, Alberta, Manitoba, North Dakota, Texas and in many other places including various sites throughout the Duvernay and Bakken formations.  We can custom make one for you in sizes ranging from 4400bbl – 57000bbl  and deploy and set it up anywhere you need it. Our bolted connections between panels ensure secure storage versus competitors that use cheaper pin type connectors that are unreliable.  Contact us today and we’ll be happy to find a solution that fits your needs!  We also offer buy, rent or lease options!  Please call 1-855-5CALROC (225762), use the quick contacts at the bottom of the page or use our contacts page if you have any questions.
