Poly-Mart RWH First Flush Tanks

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. Today, large rain harvesting First Flush Systems are generally made out of 6″ or 12″ PVC pipe. Systems using 12″ PVC pipe to create the flush chamber can be very costly and tend to be unattractive. 20 feet of 12″ PVC pipe holds roughly 115 gallons of water and is expensive. Poly-Mart First Flush Tanks offer a more aesthetically appealing option at a faction of the cost! Pricing Does Not Include Shipping Charges. Our tanks and containers are too large to ship UPS or FedEx. Shipping our 100 to 500 gallon tanks in quantities of 2 to 5 can decrease your shipping costs (per gallon) as shipping 1 tank can sometimes carry a very similar price as shipping 2 to 5! If you would like to place your order online, a tank specialist will reach out to you the following business day with a freight quote prior to capturing your funds online. Or you can Request a Freight Quote by clicking here or calling us Toll-Free at 866-822-0022 for a fast and easy freight quote!
