Start with Your Sydney Property and Project

Sydney water-tank projects vary enormously. A narrow Inner West home, a new BASIX development, a Northern Beaches property, a commercial site in Western Sydney and an acreage block near the metropolitan fringe can each require a very different tank solution.

The Tank Factory offers a comprehensive range of Australian-made Duraplas poly tanks and Kingspan Aquaplate steel tanks, giving Sydney customers practical choices across a wide variety of capacities, footprints and applications.

The Tank Factory is the online sales division of Duraplas Industries. Our Australian family-owned parent company has manufactured tanks in NSW since 1984, allowing you to purchase Duraplas poly tanks through the manufacturer’s own sales division.

Our role is to help you compare the available options, prepare the selected tank and fittings, and coordinate delivery to your nominated Sydney address.

Browse Our Complete Water Tank Range

Existing Sydney Homes and Restricted Spaces

For many established Sydney properties, the available space determines the tank before capacity does.

Useful areas may include:

• a narrow side passage beside the home;
• space behind a garage or shed;
• an area beneath a raised deck;
• a suitable section of yard or driveway for an underground tank; or
• a wider rear or side area suitable for a round tank.

Slimline Water Tanks for Sydney Homes

Duraplas slimline water tanks make productive use of spaces beside houses, garages, sheds and boundaries.

The range extends from approximately 450 to 5,000 litres, with several combinations of length, width and height. A taller upright model can provide useful storage within a shorter wall space, while a lower and longer model may fit more comfortably beneath windows or eaves.

This flexibility makes slimline tanks especially relevant for homes throughout the Inner West, Eastern Suburbs, North Shore, Northern Beaches, Sutherland Shire and established suburban areas where space is valuable.

Underground and Underdeck Tanks

Duraplas underground water tanks provide useful rainwater storage while retaining the usable area above the installation.

The Lattice underground range includes 3,000-litre and 5,000-litre models for the applicable under-yard and suitable trafficable installations.

Underdeck tanks are available in capacities from approximately 1,000 to 5,000 litres and can make effective use of suitable space beneath raised structures.

These products can be incorporated into a renovation or landscaping project by coordinating the tank dimensions, access opening, excavation, drainage and plumbing before installation work begins.

BASIX Water Tanks for Sydney New Builds and Renovations

For a new home or applicable renovation, the BASIX certificate provides an important starting point for tank selection.

The certificate may identify:

• the minimum rainwater tank capacity;
• the roof area to be connected;
• garden or outdoor-tap use;
• toilet-flushing connections;
• laundry connections;
• swimming-pool or spa top-up; and
• other water-efficiency commitments applying to the project.

Providing the BASIX certificate with your enquiry allows our team to compare the documented capacity with the available Duraplas and Kingspan tank options.

Tank location should also be considered early in the design. The most useful position generally balances:

• the available roof catchment;
• the distance to the fixtures being supplied;
• space for the pressure pump and pipework;
• access for future inspection and maintenance; and
• the route available for tank delivery.

Further information is available on our rainwater tanks for BASIX page.

Engineered Sydney Developments and On-Site Detention

Rainwater reuse storage and on-site stormwater detention perform different functions within a hydraulic system.

A Sydney development may require one tank or a connected group of tanks to provide:

• rainwater storage for household or landscape reuse;
• on-site detention storage;
• a combination of reuse and detention volumes;
• specific overflow or discharge levels;
• manifold or balance-line connections; and
• a specified detention outlet or flow-control arrangement.

For these projects, the engineer’s hydraulic drawings and site plans should guide the tank quantity, capacity, fitting heights and connection arrangement.

Our team can review the supplied plans against the tanks and fittings available from the manufacturer. Where the proposed tank arrangement differs from the approved hydraulic design, an updated or written approval from the issuing engineer provides a clear basis for quotation and manufacture.

This process helps keep the supplied tanks aligned with the documented project requirements and supports a smoother path through installation and certification.

Larger Sydney Properties, Businesses and Acreage

Where more ground area is available, round poly water tanks generally provide excellent capacity and value per litre stored.

The Duraplas round range extends from compact 360-litre tanks through to large 34,000-litre models.

Popular larger capacities include:

• 5,000 litres for gardens, sheds and supplementary household water;
• 10,000 litres for larger homes, nurseries and semi-rural properties;
• 22,700 litres for substantial household, acreage and commercial storage; and
• 34,000 litres for sites with suitable space and delivery access.

The 22,700-litre tank is available in upright and squat configurations. This provides a choice between a narrower, taller footprint and a wider, lower tank profile.

Multiple tanks can also be connected to create a larger storage system. Your plumber or hydraulic adviser can determine the balance-line diameter, overflow arrangement and pump configuration required for the intended use.

Poly or Steel: More Choice for Sydney Properties

Duraplas poly and Kingspan Aquaplate steel tanks each provide useful options for Sydney projects.

Duraplas Poly Water Tanks

Duraplas poly tanks are manufactured in Australia and are available in round, slimline, underground and underdeck configurations.

The polyethylene tank body is resistant to corrosion, making poly tanks a practical choice for coastal, harbourside and general metropolitan environments.

Round and slimline Duraplas rainwater tanks include an applicable 20-year manufacturer’s warranty, comprising 10 years repair or replacement followed by 10 years pro-rata, subject to the published warranty conditions.

Kingspan Aquaplate Steel Water Tanks

Our Kingspan Aquaplate steel water tank range includes:

• round tanks from approximately 1,000 to 27,000 litres;
• slimline tanks from approximately 1,000 to 8,000 litres;
• Modline tanks from approximately 1,000 to 7,000 litres; and
• square tanks from approximately 1,000 to 7,000 litres.

Steel tanks provide further choice where a corrugated finish, particular footprint or Aquaplate construction is preferred.

Duraplas poly tanks and Kingspan steel tanks are manufactured and delivered under separate arrangements, so a project using both tank types will involve separate product scheduling and delivery.

A Simpler Way to Narrow the Range

Our experienced team can help you move from a large online range to a practical shortlist.

1. Measure the Available Space

Confirm the maximum available:

• length;
• width;
• overall height; and
• inlet height where this affects the gutter fall.

Allowing additional clearance around the nominal tank dimensions supports plumbing, airflow, inspection and future maintenance.

2. Confirm the Intended Water Use

Let us know whether the tank will supply:

• gardens and outdoor taps;
• toilets or laundry;
• pool top-up;
• a commercial or nursery application;
• a BASIX commitment;
• an engineered stormwater system; or
• a broader household or rural water reserve.

3. Provide Any Applicable Project Documents

BASIX certificates, hydraulic plans, site plans and fitting schedules allow the proposed tank and fittings to be checked against the documented requirements.

4. Compare Suitable Tanks

We can then help identify practical round, slimline, underground, underdeck or steel options for further consideration.

5. Confirm Fittings and Delivery Access

Once the tank is selected, the outlet and overflow positions, delivery postcode and site-access details can be confirmed before the order proceeds.

Useful Standard Inclusions

Duraplas rainwater tanks are generally supplied with:

• an inlet strainer basket;
• a 90 mm overflow fitting with mesh protection;
• a WaterMark-approved 25 mm brass outlet; and
• a 25 mm ball valve.

Alternative outlet sizes and additional fittings are available for selected tanks and applications.

Round tank outlets and overflows can generally be positioned at the nominated structural fitting locations. Slimline tank fittings are positioned at the suitable rounded ends of the tank.

Your plumber can confirm the most practical fitting positions for the planned pipework before manufacture.

Water Tank Delivery Across Sydney

Duraplas poly tank delivery is available throughout Greater Sydney, subject to the selected tank, delivery postcode, route and property access.

Our delivery area includes many locations across:

• the Northern Beaches and North Shore;
• the Hills District and north-western suburbs;
• the Eastern Suburbs and Inner West;
• Western Sydney;
• South Western Sydney;
• the Sutherland Shire and southern suburbs; and
• selected metropolitan-fringe and semi-rural areas.

Sydney deliveries can involve suburban streets, loading restrictions, narrow driveways, steep blocks, overhead services and limited turning space. Sharing these details before delivery helps the team plan the most suitable vehicle and unloading approach.

Access Information That Helps

Please advise us about:

• street, driveway and gate width;
• parking or loading restrictions;
• driveway gradient and surface;
• trees, branches, balconies, eaves and powerlines;
• tight corners and turning space;
• retaining walls, stairs or changes in ground level; and
• the proposed unloading area.

The property owner determines the access available beyond the front boundary. On arrival, the driver will assess that access and select the safest practical unloading point for the vehicle, product and people assisting.

Duraplas delivery vehicles generally require approximately 3 metres of clear width and 5 metres of clear height. Where a truck-and-trailer combination is required, the complete vehicle may measure approximately 19 metres overall.

The required number of adult, able-bodied assistants depends on the tank model and is shown on the applicable product page and in our poly water tank delivery guide.

Where movement beyond the practical unloading point requires additional labour or lifting equipment, the property owner can coordinate this with a suitable local contractor.
