Building a DIY Water Cistern: Essential Tips and Guide for Preppers

What is a Water Cistern?

A water cistern is a large storage container designed to collect and store water, typically rainwater, for later use. This sustainable solution for preppers can serve multiple purposes, from providing drinking water and irrigation to ensuring a reliable backup during municipal disruptions. Building a cistern allows preppers to secure an independent water source, reducing dependency on public utilities and enhancing overall resilience.

Step-by-Step Guide to Building a Water Cistern

Select an Optimal Location that Maximizes Rainwater Capture

Choose a site adjacent to roof structures to effectively collect rainwater runoff.
Determine the Required Size Based on Household Needs

Calculate daily water consumption to decide on volume, factoring in potential drought periods.
Gather Necessary Materials Like Liners or Tanks

Ensure all tools are high quality to prevent future maintenance issues.
Excavate the Site and Lay the Foundation

Dig to the appropriate depth and lay a stable base with concrete or gravel.
Install the Cistern and Connect the Inlets and Outlets

Securely attach all connections to facilitate proper inflow and outflow.
Secure and Cover the Cistern to Prevent Contamination

Use a sealed lid and additional barriers to keep water clean and safe from debris.

Maintaining Your Water Cistern

Proper maintenance is crucial for ensuring long-term functionality:

Regularly inspect the cistern for leaks, cracks, or other damages.
Ensure filtration systems are clean and functional.
Monitor water levels to prevent overcrowding or overflow.
Check systems for debris blockages and clear them promptly.
