Todd Water & Waste Tanks

Todd Water & Waste Tanks: Marine-Grade Holding Solutions Built Saltwater Tough

When it comes to reliable onboard fluid management, Todd Marine Products has earned a well-deserved reputation among boaters who refuse to compromise. Their lineup of Water & Waste Tanks stands out in the marine industry for a combination of smart engineering, dual-use flexibility, and rigorous compliance with federal standards — all at a competitive price point.

SURPASS® Polyethylene Construction

Todd tanks are manufactured from SURPASS® polyethylene, and meet or exceed US Coast Guard (Type III CFR 177.1520) requirements. This premium-grade material is the foundation of Todd's durability claim: these tanks are tough and durable, and will not emit waste odors or change the taste of fresh potable water. Each tank is a tough, one-piece rotationally molded polyethylene design with female threaded NPT (National Pipe Threads) openings — a construction method that eliminates seams and weak points that can fail under the constant vibration and movement of a marine environment.

Dual-Use Flexibility: Water Tank or Holding Tank

One of the most practical aspects of Todd's water and waste tank design is its inherent versatility. Each Todd tank comes with the necessary pre-drilled and threaded openings so that it can be configured as either a water tank or as a holding tank. This flexible configuration makes these tanks viable solutions as FDA-approved water supply or wastewater holding tanks. Standard tanks include two 1½" fill/drain ports and two ½" vent/supply ports — which enables use as a sanitation holding tank or for potable water storage. Boaters simply swap out the pre-installed plugs to configure the tank for their specific application.

Compliance You Can Count On

Constructed of one-piece molded durable polyethylene, Todd tanks comply with FDA regulation CFR 177.1520 and meet Coast Guard standards. This dual compliance matters for both safety and peace of mind — whether you're storing drinking water for an extended offshore cruise or managing waste onboard in regulated coastal waters. All openings are female NPT (National Pipe Threads) and are located in the same relative position on one end of the tank, making installation straightforward and consistent across the product line.

Holding Tank Design Details

Todd separates their holding and water tank variants with thoughtful engineering differences. Holding tanks feature a heavier wall thickness than water tanks , providing extra structural integrity where waste containment demands it most. Each tank comes backed by a one-year warranty, and Todd also offers companion fitting kits — including straight pipe-to-hose and 90-degree adapter kits — to make installation as clean and leak-free as possible. Flexible hose connectors should always be used when connecting to the tank, as rigid or hard pipe connections void any and all warranties.
