200-Gallon Slim Tank
The 200-Gallon Slim Tank provides 200 gallons of rainwater storage in a plastic (lldpe) container measuring 60" tall x 48" wide x 16" deep. Priced between $200 and $400 ($1.00-$2.00 per gallon of capacity), this tank is an affordable entry point for homeowners new to rainwater harvesting.
About the 200-Gallon Slim Tank
Slim-profile tanks are designed to fit against walls, fences, or along the side of a house where space is limited. At 200 gallons, this tank stores nearly four times the water of a standard barrel while maintaining a footprint of only about 16 inches deep. The vertical design means water pressure at the spigot is better than barrel-style containers, reducing the need for a pump. These tanks work well for urban and suburban homes with limited yard space. The slim profile also makes them less visually intrusive than round tanks. Most models come in neutral colors that blend with siding or fencing. They are a popular upgrade for gardeners who have outgrown a single rain barrel but are not yet ready to invest in a large cistern.
Installation Guide
Installing a 200-Gallon Slim Tank is a straightforward DIY project that most homeowners can complete in under an hour. Position the barrel on a level, stable surface near a gutter downspout. A raised platform (concrete blocks, a purpose-built stand, or a wooden platform) elevates the barrel and improves water pressure at the spigot — every foot of elevation adds about 0.43 PSI of pressure.
Cut your downspout to the height of the barrel inlet and attach a downspout diverter or flex-elbow to direct water into the barrel. Ensure the overflow fitting is connected and directed away from your foundation. Install a mesh screen over the inlet to keep debris and mosquitoes out. In cold climates, disconnect and drain the barrel before the first hard freeze to prevent cracking.
Tools and Materials Needed
- Hacksaw or reciprocating saw for cutting the downspout
- Downspout diverter kit or flex-elbow connector
- Level surface or platform (concrete blocks, paver stones)
- Garden hose for the spigot connection
- Overflow hose or PVC fitting directed away from foundation
- Mosquito-proof mesh screen for the inlet
Best Uses for the 200-Gallon Slim Tank
The 200-Gallon Slim Tank is ideal for container garden watering, potted plants, flower beds, car washing, and general outdoor cleaning. Its compact size makes it perfect for urban and suburban homes with limited yard space. You can connect multiple barrels in series for increased capacity without the cost and complexity of a dedicated tank system. Most homeowners place them near their primary garden area for convenient access.
