The next step we will convert our tanks into a combination tank/bin which we call,"the bin effect." On the top deck of the tank we install three 8" equipment covers. When all three of these covers are opened up the holding tank can now be operated as a bin. This allows us to clean and scrub the tank entirely when needed, vacuum out the bottom of the tank as well as install equipment we require inside our tanks such as heaters, check valves, strainers, plumbing etc.
Our final touch to our exceptional tanks is the installment of two aluminum CALLAHEAD signage plate's one depicting contact information and the other gallonage of the tank.
The CALLAHEAD fresh water holding tanks are the lowest profile tanks available at a maximum height of either 12" or 16" allowing them to fit under almost any office trailer. Available in 10 different sizes giving us the ability to accommodate just about any size job even when there is limited space available.
Designed and created by CALLAHEAD, our fresh water holding tanks are unsurpassed in the portable sanitation industry. We perfected these tanks to provide your porcelain toilet with guaranteed fresh running water. These fresh water holding tanks are available exclusively from CALLAHEAD and nowhere else.

CALLAHEAD's waste water holding tanks were designed specifically for our porcelain toilet systems. We began this process back in 1986 by researching blank black waste tanks. Once we found the thickest strongest polyethylene tanks available we purchased multiple sizes in both dimensions and gallonage (see size chart below).
With 10 size variations between height and gallonage, we began to customize each tank to fit our requirements for the porcelain toilet systems. These low profile tanks are designed to lay flat on the ground so they may fit under just about any office trailer's crawl spaces. However, when polyethylene tanks are laid flat in this position the top deck of the tank will naturally concave due to lack of upright support. To avoid this natural occurrence we customized the tanks by installing two 4" x 4" wooden supports to eliminate our tanks from collapsing. Next, we put a 3" PVC female thread fitting in each corner of the tank along with 3" caps with cables attached to the caps to prevent loss. This process allows plumbing hook-ups to the tanks.

The next step is to turn our black waste holding tanks into a combination tank/bin. We call this the "bin effect". We installed 3 black 8" twists on the equipment covers so when all of 3 of the covers are open the holding tanks essentially becomes a bin.
There are several benefits of having our tanks operate as a bin in addition to thorough cleanings which includes equipment installation inside the tanks of our heaters, filters, check valves, pumps etc. These 8" twist equipment covers also have cables attached to prevent loss.
The final install in the creation of our waste water holding tanks are the placement of CALLAHEAD's prominent aluminum plates on top of the tanks. One plate displays our contact information and the other the gallonage of the tank. A major feature of our waste water holding tanks is the fact that they are extremely low profile standing only 12" or 16" in height. These low profile tanks can fit under the majority of office trailers and essentially eliminate the need for sewer or cesspool hook-ups.
CALLAHEAD's design of our waste water holding tanks for the porcelain toilet system is like none other in the portable sanitation industry. We thought of every detail when creating these tanks from its operation, odor control, cleanliness and very importantly its ability to fit virtually under just about every trailer's crawl space. This allows nearly every office trailer to have the greatest porcelain toilet system in their restroom that is only available from CALLAHEAD.
