Precast Concrete Underground Cistern¶

Rainwater & Storage • Est. CapEx: $19,000 USD • Lifespan: 20 Years (Standardized)

Technical Overview¶

Large-capacity residential and commercial water storage system manufactured from factory-cast reinforced concrete sections sealed on-site to form a load-bearing underground reservoir. Engineered for installation beneath driveways and high-traffic surfaces, with service life exceeding 20 years.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Rainwater & Storage
Capital Cost (CapEx)	$19,000 USD
Power / Energy	100% Gravity / Zero Power
Target Scale	Community Scale
Standard Lifespan	20 Years (Standardized)
Technology Maturity	Commercially Available
Primary Mechanism	Reinforced concrete sections are joined with rubber or synthetic gaskets and sealant to create a watertight vessel. The concrete matrix maintains high internal alkalinity and excludes all light, creating a dark, cool environment that suppresses bacterial and algal proliferation, while allowing suspended particulates to settle.
