Plastic Drums and IBC Totes for Rainwater Collection

Rainwater collection is becoming a practical option for homeowners, farms, gardens, landscaping companies, and businesses looking for better ways to reuse water. Instead of allowing rainwater to flow directly into storm drains, many people collect it from rooftops, downspouts, or outdoor surfaces and store it for later use.

For many non-potable applications, plastic drums and IBC totes can offer a practical storage solution.

Plastic drums can work well for smaller rainwater collection needs, while IBC totes provide a larger-capacity option for users who need to store more water. Both options can support water conservation, reduce reliance on treated municipal water for outdoor use, and help make better use of natural rainfall.

However, choosing the right container matters. Rainwater collection systems should be planned carefully, especially when using used or reconditioned containers.

What Is Rainwater Collection?

Rainwater collection, also known as rainwater harvesting, is the process of collecting and storing rainwater for later use.

In many basic systems, rainwater flows from a roof into a gutter, moves through a downspout, and is directed into a storage container such as a rain barrel, plastic drum, or IBC tote.

Collected rainwater is commonly used for non-potable applications such as:

Garden watering
Landscaping
Lawn care
Outdoor cleaning
Dust control
Irrigation
Greenhouse use
Washing tools or equipment
Some agricultural uses

Rainwater collected in barrels or totes should not be assumed safe for drinking, cooking, bathing, or food processing unless it has been properly treated and tested according to applicable requirements.

Why Use Plastic Containers for Rainwater Collection?

Plastic containers are popular for rainwater collection because they are durable, lightweight, and resistant to corrosion. Compared with some metal containers, plastic drums and IBC totes are easier to move, easier to handle, and less likely to rust.

Plastic containers can also be practical for outdoor storage when they are properly selected, installed, and maintained.

For rainwater collection, important container features may include:

Durable plastic construction
Suitable capacity
Secure lid or cover
Outlet valve or spigot
Overflow option
Stable base
Easy connection to hoses or downspouts
Protection from debris, pests, and sunlight

The right container depends on how much water you need to collect and how the water will be used.

Plastic Drums for Rainwater Collection

Plastic drums are a common choice for smaller rainwater collection setups. They can be used as rain barrels for gardens, landscaping, and general outdoor water storage.

A plastic drum may be a good option when the user needs a manageable container size and does not require large-volume storage.

Plastic drums can be useful for:

Backyard gardens
Small greenhouses
Outdoor cleaning
Residential landscaping
Small farms
Community gardens
Seasonal water collection

One of the main advantages of plastic drums is their size. They are easier to place near a downspout, beside a garden, or in a small outdoor area.

For rainwater use, the drum should have a secure lid or covered opening to help keep out debris, insects, animals, and contaminants. Screens or filters may also be added to reduce leaves and other material from entering the container.

IBC Totes for Rainwater Collection

IBC totes are a larger-capacity option for rainwater collection. A standard IBC tote holds approximately 1,000 litres, or 275 gallons, which makes it useful for users who need to collect and store more water.

IBC totes may be a good option for:

Larger gardens
Farms
Greenhouses
Landscaping operations
Nurseries
Industrial yards
Facilities with outdoor cleaning needs
Agricultural water storage
Larger rainwater harvesting systems

Because IBC totes include a protective cage and pallet base, they are practical for bulk storage and can be moved with suitable equipment when empty or properly handled.

IBC totes also usually include a bottom valve, which can make it easier to connect hoses or dispense water. This is helpful for irrigation, filling watering cans, or transferring water to another system.

Plastic Drum vs. IBC Tote: Which One Is Better?

The best option depends on the volume of water needed and the available space.

Plastic drums are often better for smaller spaces and lighter use. They are easier to position and may be suitable for a single downspout or small garden.

IBC totes are better when more capacity is needed. They can collect and store a much larger volume of rainwater, making them useful for farms, commercial properties, greenhouses, and larger outdoor applications.

Option	Best For	Main Advantage
Plastic drum	Small gardens, homes, light outdoor use	Compact and easy to place
IBC tote	Farms, greenhouses, larger properties, bulk storage	Larger water capacity
Multiple drums	Medium-size garden systems	Flexible setup
Multiple IBC totes	Larger water storage systems	High-volume collection

For many users, a plastic drum is a good starting point. For larger operations, an IBC tote may provide better storage capacity and efficiency.

Important Safety Considerations

Rainwater collection is useful, but it should be done carefully.

Rainwater can pick up contaminants from roofs, gutters, animals, dust, leaves, and other outdoor surfaces. Because of this, collected rainwater should generally be treated as non-potable unless proper treatment, testing, and local requirements are followed.

For most simple rain barrel or IBC tote systems, collected rainwater is best used for non-potable outdoor applications.

Businesses and homeowners should avoid using untreated collected rainwater for drinking, cooking, bathing, washing food-contact surfaces, or food processing.

If rainwater is intended for potable use, users should consult local regulations and qualified water treatment professionals.

Why Previous Contents Matter

When using a plastic drum or IBC tote for rainwater collection, the previous contents of the container are very important.

A container that previously held chemicals, oils, solvents, cleaning products, or unknown materials may not be suitable for rainwater collection, especially if the water will be used around gardens, animals, or food-producing plants.

For rainwater collection, users should avoid containers with unknown previous contents.

If the container is used or reconditioned, it should be selected carefully based on the intended use. For sensitive applications, a new container may be the better choice.

At Wenplastics, customers can review available options and choose containers based on their application, volume needs, and suitability.

Key Features to Consider

Before using plastic drums or IBC totes for rainwater collection, consider the full setup.

Secure lid or cover

A secure lid helps reduce debris, pests, and accidental access. This is especially important around children, pets, and wildlife.

Screened inlet

A screen can help keep leaves, insects, and other debris out of the container.

Overflow system

An overflow outlet helps direct excess water away from buildings, foundations, and walkways when the container becomes full.

Spigot or valve

A bottom spigot or valve makes it easier to access the water and connect a hose.

Stable base

The container should be placed on a firm, level, and stable surface. Water is heavy, and a full drum or tote can create serious weight and stability concerns.

Opaque container

Opaque containers can help reduce light exposure, which may help limit algae growth inside the container.

Easy maintenance access

The container should be easy to inspect and clean when needed.

Installation Tips for Rainwater Collection

A rainwater collection system does not need to be complicated, but it should be installed thoughtfully.

Useful tips include:

Place the container near a downspout
Use a stable and level base
Keep the container covered
Use a screen or filter at the inlet
Include an overflow outlet
Direct overflow away from the building
Check valves and fittings regularly
Clean gutters and screens as needed
Empty or winterize the container if freezing conditions may damage it
Avoid placing the container where it can tip, shift, or block access

The Capital Regional District recommends looking for rainwater containers that are durable, rot-resistant, opaque, and equipped with features such as kid-, pet-, and pest-proof covers, hose valves, and screens or filters to keep debris out and help prevent mosquitoes.

Rainwater Collection and Water Conservation

One of the main benefits of rainwater collection is water conservation.

Using collected rainwater for gardens, landscaping, and outdoor cleaning can reduce the use of treated municipal water for tasks that do not require drinking water quality.

This can be especially useful during dry seasons, watering restrictions, or periods of high outdoor water demand.

For businesses, rainwater collection can also support sustainability goals by making better use of available water resources.

Applications for Homes, Farms, and Businesses

Plastic drums and IBC totes can be used in many rainwater collection applications.

Homes and gardens

Homeowners may use plastic drums as rain barrels for watering flowers, shrubs, lawns, and ornamental plants.

Farms and agriculture

Farms may use IBC totes for larger water storage needs, irrigation support, equipment washing, or other non-potable outdoor uses.

Greenhouses and nurseries

Greenhouses and nurseries may benefit from larger rainwater storage systems to support plant care and reduce reliance on municipal water.

Landscaping companies

Landscaping businesses may use collected rainwater for irrigation, outdoor cleaning, and plant maintenance.

Industrial and commercial facilities

Facilities may collect rainwater for non-potable outdoor cleaning, dust control, or landscape maintenance.

Plastic Containers and Sustainability

Plastic drums and IBC totes can support sustainability when they are used responsibly.

These containers are durable and can often be reused for suitable applications. When a container can no longer be used, the plastic material may also be recoverable depending on the condition and previous contents.

Using plastic containers for rainwater collection can support environmental goals by:

Reducing water waste
Encouraging reuse
Supporting outdoor water conservation
Reducing demand for treated water in non-potable applications
Giving suitable containers another practical use

This connects directly with circular economy principles: keeping useful materials in service for longer and reducing unnecessary waste.

When to Choose a New Container

A new plastic drum or IBC tote may be the best choice when the application requires a clean, unused container or when the user cannot accept uncertainty about previous contents.

New containers may be preferred for:

Sensitive garden applications
Greenhouses
Nurseries
Schools or public areas
Applications near animals
Situations where previous contents are unknown
Customers who want maximum confidence in container history

For many rainwater collection projects, especially those involving garden or agricultural use, knowing the container history is important.

When Reconditioned Containers May Be Suitable

Reconditioned containers may be suitable for some non-potable rainwater collection applications, depending on their previous contents, cleaning process, condition, and intended use.

They can provide a practical and cost-effective option for applications where the water will be used for non-food, non-potable purposes.

However, users should always confirm suitability before using reconditioned containers for rainwater collection. Containers with unknown or unsuitable previous contents should be avoided.
