What to Consider
Capacity
When selecting a rainwater collection barrel, assess your water needs and usage patterns. Consider the size of your garden, frequency of watering, and any other purposes for which you intend to use collected rainwater, such as cleaning or irrigation. This helps determine the appropriate barrel capacity to meet your requirements without overflow or frequent refilling.
Also take into account the average rainfall in your area. A larger capacity barrel is advisable for regions with higher rainfall or prolonged dry spells between rain events, ensuring a sufficient supply during periods of scarcity. The size of your roof is another thing to factor in, particularly if you live in a wet climate.
Larger capacity barrels may be heavier and more challenging to maneuver, requiring additional support structures and careful placement. Penny Crispin from the Snohomish Conservation District says sizes can vary drastically to fit individual needs. “Some barrels are as small as 25 gallons, and others can hold over 100 gallons.” On average, most people will do fine with 40 or 50 gallons of capacity.
Materials
Most rain barrels, including PVC, polyethylene, and polyethylene resin varieties, are crafted from high-density plastic. This material is favored for its resistance to rot and rust, lightweight nature, and affordability, making it the most popular choice for its ease of cleaning and transportation. However, remember that plastic may degrade when exposed to sunlight, potentially affecting longevity.
Stone and clay rain barrels offer more than just aesthetic appeal; their natural properties make them ideal for rainwater collection. While they may capture smaller amounts of rainwater than other materials, their durability and insulation qualities ensure water stays cool and protected from sunlight, preventing algae growth. Their porous nature allows gradual water percolation into the soil, promoting better hydration for plants.
Wooden barrels offer a rustic look and blend well with garden surroundings. However, wood requires regular maintenance to prevent rot and decay, making it less practical for long-term use without proper care.
Features
Depending on the intended use of the rain barrel, there may be features to look out for while shopping. Standard features for rain barrels include spigots or taps for easy access to water, overflow spouts, and screen filters that are placed over intake openings to precent debris, leaves, and insects from entering the barrel. Most rain barrels also have child safety locks and some offer linking systems to connect multiple barrels for more capacity.
State and Local Restrictions
Lastly, consider regulatory restrictions or incentives related to rainwater harvesting in your area. According to Crispin, rainwater collection is regulated in some states due to issues such as water rights, the reduction of downstream water, and natural infiltration when rainwater is harvested. On the other hand, some states encourage and even provide incentives for installing rain collection systems. Check with your state regulations and programs before you install rainwater collection.

FAQs about Rain Barrels and Rain Water Collection
Is collecting rainwater legal?
Collecting rainwater is legal and even encouraged in many places as a sustainable water conservation method. However, some regions have regulations governing rainwater collection due to concerns about water rights, property rights, and potential impacts on local water systems.
Research specific laws and regulations regarding rainwater collection in your area. In places where regulations exist, obtaining permits or adhering to specific guidelines may be required. Consulting local government authorities or water resource management agencies can clarify the legality and requirements for rainwater collection in your area.
How long can water be stored in a rain barrel?
The duration water can be stored in a rain barrel depends on temperature, exposure to sunlight, and the presence of contaminants. On average, stored rainwater remains suitable for non-potable uses like watering plants or washing for several months. However, algae growth can occur more rapidly in warmer climates or during summer months, potentially affecting water quality.
Regular maintenance, like cleaning and keeping the barrel covered, can help mitigate water quality issues. Using opaque barrels and proper filtration can prolong water quality. If you intend to use stored rainwater for drinking or cooking, follow local guidelines and regularly test and treat water.
Can you drink water from a rain barrel?
Drinking water from a rain barrel should only occur when the water has been treated and tested for safety. Rainwater, while relatively clean when it falls, can pick up contaminants from various sources as it flows into the barrel, including debris, bird droppings, pollutants from roofs or gutters, and even bacteria or algae growth within the barrel itself. Consuming untreated rainwater can pose health risks due to potential contamination.
If you wish to drink water from a rain barrel, implement proper filtration, purification, and testing procedures to ensure its safety. Boiling, UV sterilization, or specialized filtration systems can make rainwater potable. However, consulting local health authorities or water quality experts for guidance on treatment methods and regulations is advisable.
How fast does a 50-gallon rain barrel fill up?
How fast a 50-gallon rain barrel fills up depends on the intensity and duration of rainfall and the size of the catchment area (such as the roof). In areas with heavy rainfall or large catchment surfaces, a 50-gallon rain barrel could fill quickly during a significant rain event, potentially within a few hours.
It may take longer to fill in regions with lighter or infrequent rainfall. Gutter size, roof pitch, and the efficiency of the collection system also influence the filling speed. Monitoring the barrel during rain events can provide a better understanding of its fill rate under local conditions. Adding multiple barrels or increasing the catchment area can enhance water collection capacity to better meet your needs.
How often should I drain my rain barrel?
Drain and refresh the water in a rain barrel periodically to prevent stagnation and maintain water quality. Algae and bacteria growth can occur more rapidly in warmer climates or during the summer, requiring more frequent drainage and cleaning (every few weeks). Draining may be less frequent in cooler or less rainy seasons (every few months).
Regular inspection for debris, sediment buildup, and signs of contamination can help determine when draining is necessary. It is also recommended that the barrel be drained before winter to prevent freezing damage.
How to Maintain Your Rain Barrel
Maintaining rain barrels and cisterns requires regular attention for optimal performance and water quality. Follow the maintenance steps outlined below for the best results.
- Install a “first flush” diverter, which Crispin explains makes maintenance easier and improves water quality by diverting the initial runoff.
- Visual inspections should be conducted regularly, particularly after heavy debris accumulation, to ensure clear water intake and overflow. Clearing leaves and debris from intake screens and diverters is essential for uninterrupted flow.
- Gutters should be cleared of debris annually, especially if trees overhang the roof. Trimming overhanging branches reduces the likelihood of clogging.
- Check seals on spigots and overflow fittings for leaks, sealing with waterproof silicone if necessary.
- Consider winterizing rain barrels with insulation or storing them in freezing climates to protect components. For occasional freezes, leaving the spigot dripping can prevent freezing.
- Annually, rinse barrels or cisterns with a hose or power washer and clear the bottom of debris.
