Rainwater & Storage • Est. CapEx: Low-cost / Locally fabricated

Technical Overview¶

An ancient, durable method for constructing watertight brick cisterns using Roman cement (a natural hydraulic lime mortar) that lasts for centuries. Ideal for off-grid and permaculture homesteads seeking non-concrete, non-plastic storage.

Key Specifications & Engineering Parameters¶

Parameter	Specification
