If you need help finding a tank that will work for you please call, fax or email us with your dimensions. We have over 1,000 molds to choose from. It is important that you give us your max dimensions so we can narrow the search to your needs.

Not all sewage tanks and water tanks are created alike. Our manufacturer provides over 1,000 tanks that are created from prefabricated molds and can lay in any configuration you need them. This ensures your ability to customize your fitting size and placement. They are polyethylene, roto-molded (rotational molded) tanks. This means they do not have seams that are known to weaken, crack and leak due to pressure and age. With the Roto-molding process the tanks are a sturdy 3/8" thick and can withstand a lifetime of permeation free use.

Lets get started.

What we need from you:
-The dimensions of the tank you require. (Remember to leave yourself room for fittings -approx 3-5 inches)

-The tanks are of a seamless construction and can be installed in any direction.
-After we find a tank with as close to, if not the exact dimensions you require, we would then require a drawing of the tank with the placement of fittings.
-All basic fittings are included in the price of the tank. This includes: Inlet, Outlet and Vent.

-Additional cost for fittings would include: Diptube for discharge and an access port.

All tanks take up to 2-3 weeks for delivery.

NO DISCHARGE ZONE NOTICE - WASHINGTON STATE

November 2016: The EPA has reviewed Washington State's petition and has determined that a no discharge zone (NDZ) can be established for Puget Sound. The EPA found that there are adequate facilities in Puget Sound for vessels to pump out their sewage with this initial determination and are accepting public comments. EPA will prepare a final determination after the public comment period of 30 days.

What does this mean to recreational boats? There are about 2,000 to 4,000 recreational vessels in the Puget Sound area that have a federally-approved treatment system called a Type I or Type II Marine Sanitation Device (MSD) These systems will have to be isolated or the MSD be removed and add a holding tank. Any vessel that has a marine toilet must have a holding tank under the NDZ.

Here is the Proposed No Discharge Zone Map
