Is This System Right for You?

This 1,500-gallon underground cistern is designed for non-potable applications — irrigation, toilet flushing, outdoor washing, and fire suppression. It is not rated for drinking water. If you need a potable system, see our 1725-Gallon Cabin Kit (For Drinking Water).

Sizing Guide

• Roof catchment area: Best suited for roofs up to ~2,000–3,000 sq ft depending on your annual rainfall
• Rainfall rule of thumb: 1" of rain on 1,000 sq ft of roof yields ~600 gallons
• Ideal for: Cabins, tiny homes, residential irrigation, off-grid properties, and supplemental water storage
• Not sure if 1,500 gallons is enough? Contact us — we'll help you size the right system for your roof area and usage

Frequently Asked Questions

• Do I need a permit? Rainwater harvesting regulations vary by state. Most states allow it freely; some (like Colorado) have restrictions. Check your local regulations or contact us and we'll point you in the right direction.
• Can I daisy-chain multiple tanks? Yes — tanks can be linked for larger storage capacity. Contact us for a custom system design.
• How deep does the tank need to be buried? The Norwesco low-profile tank is designed for shallow burial. Depth depends on your frost line and site conditions — our team can advise during your included phone consultation.
• Is professional installation required? Not required, but recommended for excavation and plumbing connections. Many customers DIY with our layout drawings and phone support.
