100 Gallon First Flush Tank | Poly-Mart Logo

Poly-Mart First Flush Tanks are used for larger rainwater harvesting applications needing to divert quantities of water close to or in excess of 100 gallons. If you think about the time that goes by in between rain storms, roofs can get dirty from dust blowing in the wind, various pollens from plants and trees, leafs, sticks, acorns, bird & squirrel droppings, etc. Poly-Mart Rain Harvesting First Flush Tanks are installed to wash your roof top by collecting the first bit of dirty water coming off of your roof in your First Flush Tank. Once it’s been filled, the water coming off of your roof will be clean. With proper plumbing, the rainwater will bypass the First Flush Tank and flow into your primary storage tank(s).

Today, large Rain Harvesting First Flush Systems are generally made out of 4″, 6″ or 12″ PVC pipe. Systems using 12″ PVC pipe to create the flush chamber can be costly and/or unattractive.  20 feet of 12″ PVC pipe holds roughly 115 gallons of water and the pipe itself is expensive. Poly-Mart First Flush Tanks offer a more aesthetically appealing option at a faction of the cost.  These tanks are designed for above ground use and are available in eleven different colors!
