Regulations can vary widely, with some regions encouraging rainwater harvesting, while others have restrictions in place. Additionally, consider the environmental impact of your system. Ensure that it includes features to prevent mosquito breeding and that overflow and runoff are managed responsibly to avoid soil erosion or water contamination. By adhering to legal guidelines and environmental best practices, you can create a system that not only serves your needs but also protects the ecosystem you call home.
Assessing Your Water Needs
Calculating Daily Water Usage
To ensure a reliable water supply for your wilderness home, it’s crucial to calculate your daily water usage accurately. Start by considering the basic needs: drinking, cooking, bathing, laundry, dishwashing, and toilet use. For example, drinking and cooking may require 3-5 gallons per person per day, while a navy shower with a low-flow showerhead might use 5-10 gallons. High-efficiency washers can use 10-25 gallons per load, and hand washing dishes may require 2-5 gallons. If you have a composting toilet, water usage is zero, but low-flow toilets use 1-5 gallons per flush. Don’t forget to include water for pets, cleaning, and any livestock, which could be 5-10 gallons per day for larger animals. By adding these figures, a single person practicing conservation could use 20-40 gallons per day, with additional family members adding 5-10 gallons each.
Factors Influencing Water Demand
Several factors can influence your water demand. The number of residents, presence of guests, water-based appliances, and personal habits all play a role. Livestock and gardening needs can significantly increase water usage. Additionally, the efficiency of water fixtures and the implementation of water-saving practices can either raise or lower your overall demand.
Planning for Seasonal Variations
Seasonal changes can affect water availability and needs. During dry seasons or droughts, water conservation becomes even more critical, and usage may need to be restricted. Conversely, in wet seasons, you may have an abundance of water. It’s essential to track your water usage and adjust your collection and storage strategies accordingly. Consider the average rainfall in your area and plan for periods when water may be scarce.
Emergency Reserves and Storage Solutions
Emergencies can disrupt your water supply, so it’s wise to have reserves. A good rule of thumb is to store at least a two-week supply of water for each household member, including pets and livestock. For storage solutions, rain barrels are a simple and efficient option. A 55-gallon barrel can be filled with just 0.3 inches of rain from a 300-square-foot roof area. Larger cisterns or tanks with a capacity of 2,500 gallons or more ensure ample reserves and can be placed above or below ground. Remember to include overflow features in your system to manage excess water during heavy rainfall and to prevent water from stagnating, which can attract mosquitoes and promote algae growth.
In conclusion, assessing your water needs involves careful calculation of daily usage, understanding the factors that influence demand, planning for seasonal variations, and ensuring you have adequate emergency reserves. By taking these steps, you can design a rainwater collection system that meets the needs of your wilderness home.
Components of a Rainwater Collection System
Catchment Areas: Roofs and Gutters
The foundation of any rainwater collection system is the catchment area. In most residential settings, this is typically the roof of your home. The material of your roof can affect the quality of the water collected; thus, it is important to consider non-toxic materials that do not leach chemicals into the water. Gutters are then installed along the roofline to channel the water down into the conveyance system. It is essential to have a leaf guard to prevent debris from clogging the system and a first flush diverter to ensure the initial runoff, which may contain contaminants, is separated from the water that is stored.
Conveyance Systems: Downspouts and Piping
Once the rainwater is collected from the roof, it needs to be transported to the storage tanks. This is done through a series of downspouts and pipes. The conveyance system should be designed to minimize leaks and reduce maintenance. It is also crucial to ensure that the materials used for piping are suitable for potable water if the collected rainwater is intended for drinking.
Storage Options: Tanks and Cisterns
Storage is a critical component of a rainwater collection system. Tanks or cisterns can be made from various materials, but it is vital to use food-grade containers that have never been used to store chemicals or fuels. The size of the storage system will depend on your water needs and the amount of rainfall your area receives. Tanks should be covered and preferably opaque to prevent algae growth, and placed on a stable, level foundation to ensure proper functioning.
Filtration and Purification
Before rainwater can be used for drinking, it must be filtered and purified to remove any contaminants. Filtration systems can range from simple mesh filters to remove debris to more complex systems that eliminate pathogens and chemicals. Purification methods such as UV light, chlorination, or reverse osmosis may be necessary to ensure the water is safe for consumption.
Delivery Systems: Pumps and Faucets
The final step in a rainwater collection system is the delivery of water to the point of use. This can be achieved through gravity if the storage tanks are elevated, but in most cases, a pump is required to provide adequate water pressure. The delivery system should be integrated with your home’s existing plumbing to allow for easy access to the rainwater for household tasks, irrigation, or emergency use.
By understanding and carefully planning each component of a rainwater collection system, you can ensure a reliable and efficient supply of water for your wilderness home. With the right design, your system will not only provide water security but also contribute to sustainable living and water conservation.

The catchment area, typically a roof, should be large enough to capture sufficient rainwater for your needs. Consider the size, slope, and material of your roof, as well as the average rainfall in your area. A steeper slope will aid in water runoff, while materials like metal or slate are more efficient for water collection than absorbent materials like green roofs.
Sizing Your Storage Tank
The size of your storage tank is critical and should be based on your calculated daily water usage, the catchment area’s size, and the local rainfall pattern. To avoid running out of water during dry spells, your tank should be large enough to store water collected during periods of heavy rainfall. A general rule of thumb is that 1 inch of rainfall on a 1,000 square-foot roof can yield approximately 623 gallons of water. Use this as a starting point to determine the tank size that will meet your needs throughout the year.
Choosing the Right Materials
Selecting materials that are durable, non-toxic, and suitable for potable water (if intended for consumption) is essential. For gutters and downspouts, materials like PVC, aluminum, or galvanized steel are commonly used. For storage tanks, options include polyethylene, fiberglass, or stainless steel. Each material has its advantages and potential drawbacks, such as UV sensitivity or susceptibility to cracking, so choose based on your environmental conditions and budget.
Integrating with Existing Plumbing
Integrating your rainwater collection system with existing plumbing can be complex and may require professional assistance. If you plan to use the water indoors, consider how you will connect the storage tank to your home’s plumbing system. This may involve installing a pump to provide adequate water pressure and ensuring that all components are compatible with your existing pipes. It’s also important to include backflow prevention to keep rainwater from contaminating your potable water supply.
