How to Build an Underground Water Cistern: A Complete Guide

In times of emergency, having a reliable source of water is crucial. An underground water cistern can serve as an effective solution for emergency water storage. This comprehensive guide will outline the steps needed to build a DIY water cistern, ensuring you are prepared for any situation.

Why Build an Underground Water Cistern?

Building an underground water tank offers numerous benefits, including:

• Sustainability: It allows for rainwater collection, reducing reliance on municipal sources.
• Space Saving: An underground system takes up less surface area compared to above-ground options.
• Emergency Preparedness: It ensures water availability during droughts or natural disasters.

Step-by-Step Guide to Building Your Underground Water Cistern

Follow these steps to create your DIY underground water storage tank:

Step 1: Planning and Regulations

Before you start digging, check local water storage regulations. Consult your local government to ensure your cistern complies with all necessary codes. Consider the size of the cistern based on your household needs and potential rainfall.

Step 2: Choose the Best Materials

Choosing the right materials is crucial for constructing a durable cistern. Here are some recommended options:

• Concrete: Highly durable and resistant to leaks.
• Plastic: Lightweight and easier to install but may have a shorter lifespan.
• Fiberglass: Resistant to corrosion and easy to maintain.

Step 3: Digging the Cistern

Once you have your materials, it's time to dig. The hole should be at least several feet deeper than the height of the cistern to ensure stability. Use a shovel or hire a backhoe for larger projects.

Step 4: Installing the Cistern

Carefully lower the cistern into the hole. Ensure it is level and surrounded by gravel for drainage. This will help prevent water from accumulating around the tank, which could cause structural issues.

Step 5: Connecting the Water Filtration System

A water filtration system is essential for maintaining the quality of the water stored in your cistern. Connect a filtration system that can handle the volume of water you expect to collect, ensuring safe drinking water during emergencies.

Step 6: Rainwater Collection System

Install a rainwater collection system that directs water from your roof into the cistern. This could include gutters and downspouts connected to a first-flush diverter to reduce debris entering the tank.

Step 7: Cistern Maintenance

Regular cistern maintenance is vital. Check for leaks, clean debris from the collection system, and inspect the filtration system. It's advisable to conduct maintenance at least once a year.
