Rainwater Collection Tanks

Poly-Mart's Rainwater Harvesting Tanks are a trusted industry-leading product assembled specifically for collecting and utilizing rainwater.

Harvesting natural precipitation adds to the availability of water in drought, allows you to care for your lawn and garden regardless of local restrictions or utility surcharges, and helps to mitigate flooding during storms. As an added benefit, rainwater's zero hardness and neutral pH extend the life of appliances by avoiding the buildup of scales and corrosion—all with a resource already provided from nature.

Watching rain fall to the ground and into a storm drain is a frustrating sight for people who appreciate conservation. Capture that water with rainwater collection tanks from Polytank-Mart.com. Whether you're looking for 150- or 1,000-gallon rainwater harvesting tanks, we have the sizes and features that you demand. Three outlets adorn your tank so that you can deal with overflow or a controlled withdrawal through a garden hose. Our rain collection barrels also come in a variety of colors. Green, black and gray will match with nearly any outdoor decor where the tank resides.

Poly-Mart rain harvesting tanks are designed to protect and store the water. A strainer at the entrance point keeps pests and debris from contaminating these rainwater storage tanks. Simply clean out the strainer on occasion to maintain the system. Water your backyard or crops or wash a car with the rainwater. There are no limits to the usefulness of these tanks.

Who should harvest rainwater?

Rainwater Harvesting Tanks

“More [rainwater collection systems] are being installed by the urban home gardener seeking healthier plants, the weekend cabin owner, and the homeowner intent upon the ‘green’ building practices – all seeking a sustainable, high-quality water source.”
The Texas Manual on Rainwater Harvesting, 3rd Edition, Texas Water Development Board, 2005 (PDF / 2.42 MB)


Rainwater Collection Systems are appropriate for almost any environment but are particularly valuable to drought-stricken areas. Every 1,000 square feet of roof space has the potential to capture about 600 gallons of water per inch of rain.

Before deciding on the total capacity of tank(s) you want, determine how much rainfall you have the capacity to collect. View a quick reference chart, or if you need more precision, utilize the Texas AgriLife Extension Service's three-year calculator (.xlsx format).

For standard tanks, Black and Dark Green limit the most light from entering the tank to prevent algae growth, but we offer a premier line of SunShield Tanks boasting zero light penetration in all colors.

*All Tanks of all colors are BPA-Free and manufactured with resin that complies with U.S. Food and Drug Administration regulation 21CFR 177.1520 (1) 3.1 and 3.2 for storage of potable water
