Custom Holding Tanks for Marine Vessels (Freshwater, Grey Water & Wastewater)

Many larger boats have a clean water system and a wastewater system. Clean water is also known as potable or fresh water; Wastewater is known as black water or gray water.

If there’s a marine or RV tank available in stainless steel, or aluminum, we can fabricate the same shape and size container out of lighter-weight plastic materials, including:

Polypropylene
PVC
Polyethylene
