Rainwater Collection Tanks

Flexible Pillow Tanks for Rainwater Collection

Question: Hello, I am in need of pillow rainwater collection tanks. I am planning a rainwater collection system for the upcoming spring/summer. I was hoping these tanks could be used to supply my watering needs, such as my surrounding trees and gardens. My problem is finding a tank that can be used in both hot and cold temperatures. Ideally I would need something that could handle -20 F to 110 F.

Answer: Collapsible pillow tanks are an excellent choice for grey water/rainwater collection systems. These tanks can be made in any capacity from 1 to 210,000 gallons and often feature a low profile for convenient storage around your home or facility. In addition to size, there are a couple of different reasons why this tank might be able to work well for the situation you have described.

Pillow Tank Fabrics

Fabrics used on these pillow tanks are extremely versatile and are often implemented in extreme temperature ranges. Tank fabrics have been rated to handle temperatures between:

  • Low: -58 F
  • High: 180 F

When used for rainwater, tank fabrics also have the option of featuring an inner lining that is FDA approved for potable water. This helps equip the tank for the potential of inside liquids being used for drinking water.

The flexible Storage Tank can easily be constructed in sizes anywhere from 1 to 210,000 gallons, including the specific capacities you have mentioned of either 500 or 1,000 gallons.
