Centreline)¶

Sand Dams & Civil Works • Est. CapEx: $1 USD • Lifespan: 7–15 Years

Technical Overview¶

Engineered earthen structures for storing mine tailings (waste slurry) using upstream, downstream, or centreline construction methods. These are critical for mining operations to impound tailings safely, with modern designs incorporating soil mechanics and seismic stability.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Sand Dams & Civil Works
Capital Cost (CapEx)	$1 USD
Power / Energy	Electric / Motorized
Target Scale	Household (5–10 people)
Standard Lifespan	7–15 Years
Technology Maturity	Commercially Available
Primary Mechanism	Starter dam built first, then raised progressively using tailings or borrow materials. Upstream dams rely on tailings for support (cheaper but less stable), downstream dams require more material but offer higher stability, and centreline dams maintain a fixed centerline for balanced performance. Internal drains and impervious cores control seepage and prevent liquefaction.
