Quick Answer
Eco-friendly options for cistern construction do exist, using materials like recycled plastic, earthbags, and rammed earth. These alternatives reduce waste and minimize environmental impact. Concrete cisterns can also be made more sustainable by using locally sourced materials and incorporating recycled aggregate.
Sustainable Materials
When building a cistern, it’s essential to consider the environmental impact of the materials used. One option is to use recycled plastic, which can be made into durable and leak-proof cisterns. For example, HDPE (High-Density Polyethylene) plastic sheets can be used to line cisterns, reducing the need for conventional concrete or steel.
Buried Concrete Cisterns
For those who prefer traditional construction methods, buried concrete cisterns can still be made more sustainable. Using a slipform paver, it’s possible to build a 10,000-gallon cistern in just a few days, minimizing labor costs and environmental impact. Additionally, incorporating recycled aggregate, such as crushed concrete, into the concrete mix can reduce waste and conserve natural resources.
Innovative Techniques
Another approach is to use innovative techniques like earthbag construction or rammed earth. These methods use natural and locally sourced materials, such as soil or gravel, to build a cistern. Earthbag cisterns can be made using polypropylene bags filled with soil or gravel, which are then stacked and stabilized with barbed wire or chicken wire. This approach reduces waste and minimizes the need for imported materials.
