Harvesting Rainwater
*best for health
Harvesting rainwater is one of the purest and most sustainable ways to secure a reliable water source while promoting health and environmental stewardship. Rainwater, naturally soft and free from many of the chemicals and additives found in treated municipal supplies, offers a cleaner and more natural option for hydration, personal care routines and household use. Its minimal mineral content reduces the risk of scaling in plumbing systems, and when properly filtered and stored, it provides a safe, refreshing water source that supports overall well-being.
Beyond hydration, using rainwater can lower exposure to contaminants found in surface or groundwater sources, contributing to healthier skin, hair, and even garden produce grown with this pure resource. For these reasons, rainwater harvesting stands out as a healthy, eco-friendly choice, although its suitability depends on its source, quality, and how it is managed.
Natural Purity
Minimal Chemical Treatment: Rainwater is naturally distilled through the evaporation process, meaning it is free from many of the chemicals and additives found in municipal water supplies, such as chlorine and fluoride.
Low Mineral Content
Rainwater collected directly from the sky, as a rule, contains far fewer inorganic health disrupting minerals, compared to regularly supplied municipality chemical ladened tap water. In effect, this means rainwater can supply maximum healthful hydration while also being gentler on skin and hair.
Environmental Benefits
Reduces Demand on Municipal Systems: Using rainwater for drinking, personal and domestic cleaning, irrigation, flushing toilets, or other non-potable uses helps reduce the demand on local water supplies and sewage systems.
Conserves Potable Water: By using rainwater for non-potable purposes, we conserve treated potable water for drinking and other essential uses.
Cost Savings
Lower Water Bills: Collecting and using rainwater can reduce reliance on municipal water, leading to lower water bills.
Reduced Energy Costs: If rainwater is used for irrigation or landscaping, it can help reduce the energy required to pump and treat water.
Gardening & Agriculture
Better for Plants: Rainwater is typically softer and contains fewer salts and chemicals than tap water, which can be better for plants. It helps maintain soil structure and health.
Nutriment Rich: It often contains nitrogen and other nutrients beneficial to plant growth, which can enhance soil fertility.
Reduced chemical Exposure
Fewer Additives: By using rainwater, we avoid exposure to chemicals often used in municipal water treatment, such as chlorine and chloramines, which can be beneficial for people with sensitive skin or allergies.
Self-Sufficiency & Resilience
Independance: Harvesting rainwater allows for greater self-sufficiency, particularly in areas with inconsistent municipal water supply or during drought conditions.
Emergency Supply: It provides a backup water source during emergencies or natural disasters, ensuring a continuous supply of water when municipal systems may be disrupted.
Quality Control
Direct Monitoring: With a well-maintained rainwater harvesting system, communitarians can monitor and control the quality of the water, ensuring it meets our standards for use.
Considerations for Using Rainwater
While rainwater has many benefits, there are also important considerations to ensure its safety and effectiveness:
Contamination Risks: Rainwater can be contaminated by pollutants in the air, roofing materials, or storage systems. Proper filtration and treatment are essential for making it safe, especially for potable uses.
Storage and Maintenance: Rainwater systems require regular maintenance to prevent algae growth, insect contamination, and other issues. Proper storage tanks and filtration systems are crucial.
Overall, rainwater can be a valuable resource when managed correctly, offering environmental, economic, and personal benefits.
Rainwater Harvesting System Set-up
1. System Plan
– Determine Required Quantity: Decide how the rainwater will be used (e.g., primarily drinking water and bathing.)
2. Collecting Rain Water
– Roof & Gutter System: The most common method is to collect rainwater from your roof. Ensure your roof is made of non-toxic materials, as some roofing materials can leach chemicals.
– Gutters & Downspouts: Install gutters along the edges of your roof to channel rainwater into downspouts. Make sure they are kept clean and free from debris.
3. Directing Water to a Storage Tank
– First Flush Diverter: To improve water quality, install a first flush diverter that diverts the initial runoff, which may contain contaminants from the roof.
– Storage Tank: Choose a storage tank that suits your needs. Tanks can be made of plastic, metal, or concrete and come in various sizes. Place it on a stable surface and ensure it’s sealed to prevent contamination.
4. Filtering and Treatment
– Filters: Install filters to remove debris and particulates from the collected rainwater. You can use mesh filters on the gutters and more advanced filters before the water enters the storage tank.
– Treatment: For Drinking water, further treatment is necessary. Common methods include UV sterilization, carbon filtration, or chemical treatments. For non-potable uses, basic filtering might be sufficient.
5. Distribution System
– Pipes and Hoses: Set up a distribution system to move water from the storage tank to where it’s needed. This can include pumps, pipes, and hoses.
– Use: Depending on your needs, you may use the water for irrigation, washing, or other purposes. Make sure to keep non-potable water separate from potable water systems.
6. Maintenance
– Regular Checks: Clean gutters, filters, and the storage tank regularly to prevent blockages and contamination.
– Inspect for Leaks: Regularly inspect the system for leaks or damage and repair as needed.
7. Safety & Other Considerations
– Avoid Contamination: Ensure all components are made from safe materials and are properly maintained to avoid contamination.
– Monitor Water Quality: Regularly test the water quality if you’re using it for potable purposes.
By following these steps, the communal unions can set up effective rainwater harvesting systems that provide significant health, environmental and cost benefits.
