Are Slim Line Water Tanks a Good Choice for Narrow Side Access Areas?

A narrow strip between a house and boundary fence might seem like wasted space, but it can sometimes provide the perfect location for rainwater storage. For properties with limited outdoor space, slim line water tanks offer a practical alternative to wider, conventional tank designs. Their elongated profile allows them to sit closer to walls and fences while making use of areas that may otherwise be difficult to utilise.

For properties where collected rainwater needs to be moved efficiently around the site, water pumps tanks systems can also form part of the overall planning process. The pump configuration, tank location and intended water use all need to work together to create a practical setup.

The Side Access Problem

Imagine a typical Melbourne home with a narrow passage running between the garage and boundary fence. There is enough room for people to walk through, but not enough width for a large round water tank.

Moving the tank further into the backyard isn't ideal either. It could take away valuable garden space or interfere with entertaining areas.

This is where a narrow-profile tank can change the equation.

Instead of asking, “Where can a large tank fit?”, homeowners can ask, “How can the available space be used more effectively?”

Why Shape Matters

Traditional round tanks can require considerable floor space because of their diameter. Slim-profile tanks are designed differently, with their shape allowing them to occupy narrower sections of a property.

This can make them particularly suitable for:

• Narrow side passages
• Areas beside garages
• Boundary-side spaces
• Compact courtyards
• Residential properties with restricted access

The available width, height and length of the installation area still need to be considered before selecting a tank.

But Will It Actually Fit?

This is where measurements become important.

A side access area may look suitable from a distance, but small details can affect whether a tank can be positioned and maintained effectively.

Consider the available:

Width — Is there enough room for the tank without restricting access?

Length — Can the tank extend along the property without interfering with doors, gates or pathways?

Height — Will its height work beneath eaves, windows or other structures?

Access — Can the tank be transported to its intended position?

Connections — Is there suitable space for plumbing, outlets and other components?

A tank should not simply fit into the space; it should remain accessible and functional once installed.

What About Water Usage?

The right tank size also depends on what the stored water will be used for.

Someone collecting water primarily for garden irrigation may have different requirements from a household using rainwater for toilets, laundry or other applications.

A larger tank isn't automatically better if the property cannot accommodate it comfortably. Conversely, choosing a tank that's too small may limit the benefits of collecting rainwater.

The ideal capacity is therefore influenced by available space, roof catchment, rainfall patterns and intended water use.

When space is limited, choosing the right tank design can turn an awkward side passage into a valuable part of a home's rainwater collection system.
