If you're living in Canada, have you considered rainwater harvesting? After all, Canada has an average precipitation of over 530 mm of rain per year, and some cities get significantly more than this. However, you need to pick the right cistern to make the most out of this ancient practice.


Cisterns are for your water storage and can be above or below ground. There are several considerations when choosing a cistern, such as the material. One of the best options is a concrete cistern for collecting rainwater.


Here is everything you need to know about concrete cisterns for rainwater harvesting.


Using Precast Concrete Cisterns for Rainwater Harvesting

Rainwater harvesting is a sustainable practice that has gained popularity in recent years, and for good reason. It allows you to collect and store rainwater for various purposes, such as landscape irrigation, flushing toilets, and even drinking water in some cases. One essential component of a rainwater harvesting system is the storage vessel, and precast concrete cisterns offer a durable and eco-friendly solution for this purpose. In this blog post, we'll explore the benefits of using precast concrete cisterns for rainwater harvesting.


What Are Precast Concrete Cisterns?

Precast concrete cisterns are large, watertight containers made from high-quality concrete. They are manufactured off-site in controlled conditions, ensuring uniformity and quality. These cisterns are designed to efficiently collect and store rainwater for later use. Let's delve into the advantages of choosing precast concrete cisterns for your rainwater harvesting needs:


1. Durability and Longevity

One of the most significant advantages of precast concrete cisterns is their exceptional durability and longevity. Concrete is a robust material that can withstand harsh weather conditions, extreme temperatures, and UV exposure without deteriorating. Unlike some other materials, concrete cisterns won't corrode or rust over time, ensuring a long lifespan for your rainwater harvesting system.


2. Eco-Friendly

Concrete is an environmentally friendly choice for rainwater cisterns. It is made from natural materials, and its production has a lower environmental impact compared to other materials like plastic. Additionally, concrete cisterns can be recycled or repurposed at the end of their service life, minimizing waste.


3. Low Maintenance

Precast concrete cisterns require minimal maintenance. Unlike some other materials that may require regular cleaning or inspections, concrete cisterns can largely be left untouched. This makes them a hassle-free choice for homeowners and businesses looking to harvest rainwater without ongoing maintenance efforts.

4. Pest and UV Resistance

Concrete cisterns are pest-resistant, preventing insects and rodents from entering and contaminating your stored rainwater. Additionally, they are UV resistant, so you don't have to worry about the sun's rays degrading the material over time.


5. Excellent Insulation Properties

Concrete has natural insulating properties, which helps regulate the temperature of the stored rainwater. This can be especially beneficial if you plan to use the harvested rainwater for purposes like irrigation, where temperature fluctuations can impact plant health.


6. Customizable Sizes

Precast concrete cisterns come in a range of sizes to suit your specific needs. Whether you have limited space or require a large storage capacity, there's a concrete cistern option for you.


Conclusion Incorporating precast concrete cisterns into your rainwater harvesting system is a sustainable and durable choice. These cisterns offer longevity, low maintenance, and environmental benefits that make them an ideal solution for those looking to harness the power of rainwater for a greener and more eco-friendly future. Consider precast concrete cisterns as a reliable component of your rainwater harvesting setup and take a step towards sustainable water use.


Why Homeowners Should Consider Getting a Cistern for Rainwater Harvesting

Rainwater harvesting is becoming increasingly popular among homeowners, and for good reason. It's an eco-friendly practice that not only conserves water but also offers numerous benefits for households. Let's delve into the compelling reasons why homeowners should seriously consider getting a cistern for rainwater harvesting, supported by some enlightening statistics:


1. Water Conservation and Cost Savings

According to the U.S. Environmental Protection Agency (EPA), the average American family uses more than 300 gallons of water per day at home. However, nearly 30% of this water is used for outdoor purposes like irrigation.

A single inch of rainfall on a 1,000 square-foot roof can yield around 600 gallons of water. By harvesting rainwater for outdoor use, homeowners can significantly reduce their reliance on municipal water supplies, leading to substantial cost savings.


2. Mitigating Water Scarcity

The United Nations reports that by 2025, an estimated 1.8 billion people will be living in regions with absolute water scarcity. Climate change and population growth are exacerbating water scarcity issues worldwide.

Rainwater harvesting helps alleviate the pressure on local water sources, reducing the risk of water scarcity in communities. By collecting rainwater, homeowners contribute to a more sustainable water future.


3. Environmental Benefits

According to the American Rainwater Catchment Systems Association (ARCSA), the average American household can collect about 40,000 gallons of rainwater per year from a 1,000 square-foot roof. This reduces the demand on traditional water sources and helps protect ecosystems.

Rainwater harvesting reduces stormwater runoff, which can carry pollutants into rivers and streams, negatively impacting aquatic life. By capturing rainwater, homeowners play a role in preserving local water quality.


4. Drought Resilience

Droughts are becoming more frequent and severe due to climate change. According to the National Oceanic and Atmospheric Administration (NOAA), the U.S. experiences an average of 10-20 drought events annually, causing billions of dollars in damages.

A cistern filled with harvested rainwater provides homeowners with a backup water source during droughts or water restrictions. This can help maintain landscaping and gardens, preserving curb appeal and property value.


5. Return on Investment (ROI)

Installing a rainwater harvesting system, including a cistern, can provide a solid ROI over time. The savings on water bills and potential rebates or incentives offered by local governments can make the initial investment worthwhile.


6. Sustainable Landscaping

The U.S. Environmental Protection Agency (EPA) estimates that landscape irrigation accounts for nearly one-third of all residential water use, totaling nearly 9 billion gallons per day.

Harvested rainwater is an ideal source for irrigating lawns, gardens, and plants. Homeowners can maintain lush and healthy landscapes while reducing the strain on municipal water supplies.


In conclusion, homeowners should seriously consider getting a cistern for rainwater harvesting as it offers a sustainable solution to water conservation, cost savings, and environmental protection. With the global water crisis.
