Open Top Vertical Bulk Storage Tanks

Open top vertical bulk storage tanks are vertical vessels with flat bottoms and cylindrical side walls with flared top lips. These tanks are roto-molded from natural, translucent (white), medium density polyethylene (MDPE) with UV inhibitors. Other colors are available.

Customers choose these modestly priced open top storage tanks for applications where easy access to the liquid surface or contents is important. These tanks are free standing – they do not require a support stand.

These poly tanks are suitable for holding many liquids, at densities up to 1.7 in indoor or outdoor service. Typical uses:

Collection tanks

Temporary liquid storage tanks

Holding tanks

Surge tanks

Balance tanks

Chemical supply tanks

Day tanks

Batch tanks

Open top tanks can also serve as secondary containment for vertical tanks of smaller diameter.

Every open top bulk storage tank is equipped with an outlet bulkhead fitting on the lower side wall. Customization allows you to single source a tank with accessories. Just tell us what you need.

Open top tanks can also be used to provide instant containment for smaller diameter vertical storage tanks where regulations require containment (see photo).

Standard open top bulk storage tanks are usually available from stock in most sizes. Colored tanks, thicker walls and specially configured tanks are available on short lead times.
