Large Cisterns (300 gal and up)
When you want serious storage—enough to irrigate the lawn, top off livestock troughs, or run a pressure-washer without tapping the meter—step up to a 500-, 1,000-, or even 2,500-gallon tank system.
Why go big?
- Storm efficiency. A single 1" rain on 1,000 sq ft of roof yields ~630 gal. A large cistern captures that volume instead of watching it overflow after the first barrel fills
- Weeks of drought reserve. A 1,000-gal tank can water a 400 sq ft garden for 8–10 restriction weeks—no hose bib required.
- Foundation relief. Diverting thousands of gallons into storage keeps clay soils drier at the slab edge.
- Rebate-friendly. Many Texas utilities offer bill credits or cash incentives once capacity exceeds 300 gal.
