Rainwater Tanks for Coffs Harbour Homes, Farms and Businesses

The Tank Factory offers a broad selection of rainwater tanks for properties throughout Coffs Harbour, the Coffs Coast and surrounding Mid North Coast areas.

Our range includes round, slimline, underground and underdeck Duraplas poly tanks, together with round, slimline, Modline and square Kingspan Aquaplate steel tanks.

The Tank Factory is the online sales division of Duraplas Industries. Duraplas remains an Australian family-owned manufacturer and has been producing tanks since 1984. This gives customers the practical benefit of purchasing through the manufacturer’s own sales division, backed by established regional operations and long-term product support.

Local Support from Duraplas Coffs Coast

Duraplas has an established Coffs Coast outlet at 311 Pacific Highway, Coffs Harbour. This local presence supports the coordination of Duraplas poly tank deliveries throughout the region and provides a practical connection between customers, the sales team and the regional delivery operation.

The Coffs Coast outlet forms part of the wider Duraplas network serving the NSW coast. Delivery availability, freight and timing depend on the selected tank, postcode, current delivery schedule and property access.

Choosing the Right Tank for Your Property

The most suitable tank is determined by more than storage capacity alone. Before selecting a model, consider:

• the available length, width and height;
• the roof area that can be connected to the tank;
• the intended use and expected demand for the water;
• the location of downpipes and stormwater connections;
• space for a pump, pipework and maintenance access; and
• the delivery route into or beside the property.

Tank dimensions are nominal and can vary slightly through the manufacturing process. Allowing additional space around the tank also makes plumbing, inspection, airflow and future maintenance easier.

Round Poly Water Tanks

Round poly water tanks generally provide the greatest storage capacity for the available purchase price. The Duraplas round tank range extends from compact 360-litre models through to large 34,000-litre tanks.

Popular capacities include 5,000 litres for residential and garden use, 10,000 litres for larger properties and 22,700 litres for substantial household, rural and commercial storage requirements.

The 22,700-litre Duraplas round tank is one of the most frequently selected larger tanks in the range. It provides substantial storage while retaining a practical above-ground footprint for many acreage, farming and larger residential properties.

Where greater storage is required, several tanks can often be connected to form one system. The balance lines, overflow arrangement, pipe sizes and hydraulic layout should be confirmed by the customer’s licensed plumber or relevant project professional.

Slimline Poly Water Tanks

Slimline poly water tanks make productive use of narrow areas beside homes, garages, sheds and commercial buildings.

The Duraplas slimline range extends from compact household tanks through to 5,000-litre models. Different combinations of width, length and height are available, allowing customers to select a shape that makes effective use of the available site.

For example, some customers may benefit from a taller upright tank with a shorter length, while another property may be better suited to a lower and longer design.

Underground and Underdeck Water Tanks

Duraplas underground water tanks provide useful storage while preserving the usable area above the installation. The Lattice underground range includes 3,000-litre and 5,000-litre models designed for the applicable under-yard or trafficable installation method.

Underdeck tanks provide another space-efficient option for suitable raised homes, decks and structures. Available capacities extend from approximately 1,000 to 5,000 litres.

These projects benefit from early planning between the property owner, excavator, plumber and any relevant engineer. Customers arrange excavation, lifting equipment, installation and plumbing through their selected qualified contractors.

Kingspan Aquaplate Steel Water Tanks

Our Kingspan Aquaplate steel water tank range provides further options in round, slimline, Modline and square configurations.

Round steel tanks extend to approximately 27,000 litres, while slimline and compact steel configurations are available for properties requiring a different footprint or finish.

Kingspan manufactures and delivers the steel range under separate freight, warranty and site-access arrangements. Poly and steel tanks included in the same project may therefore arrive on different vehicles and delivery dates.

How Much Rainwater Can a Coffs Harbour Roof Collect?

Coffs Harbour has strong rainwater-harvesting potential. The Bureau of Meteorology’s operating Coffs Harbour Airport station records mean annual rainfall of approximately 1,728 millimetres across its available record commencing in 2013.

As a general calculation, 1 millimetre of rainfall falling on 1 square metre of connected roof represents approximately 1 litre of potential catchment before allowing for first-flush diversion, gutter overflow, evaporation, splash and other collection losses.

For example:

150 m² of connected roof × 1,728 mm of rainfall = approximately 259,200 litres of theoretical annual catchment.

This does not mean a property needs a tank of that capacity. A practical tank size balances:

• the water that can be collected;
• the frequency and volume of water use;
• the available installation space; and
• the desired reserve between rainfall events.

Our rainwater catchment calculator can assist with an initial comparison.

Useful Applications for Stored Rainwater

Depending on the plumbing arrangement and applicable local requirements, stored rainwater may support:

• garden and lawn watering;
• vegetable gardens and orchards;
• car and outdoor-area washing;
• toilet flushing;
• cold-water laundry connections;
• swimming-pool top-up;
• nursery, landscaping and horticultural use;
• stock and rural water requirements; and
• selected business and commercial applications.

Regular use creates storage space for the next rainfall event. For many urban properties, a well-used smaller tank can provide excellent practical value, while larger tanks offer greater reserve capacity for acreage, rural and higher-demand applications.

Coffs Harbour Rainwater Tank Registration and Plumbing

City of Coffs Harbour has specific requirements for rainwater tanks installed on urban properties connected to the reticulated town-water supply.

The City currently requires the property owner to submit an urban rainwater tank registration form at least 10 working days before work begins.

The City’s current policy also requires:

• installation work to be completed by a licensed plumber;
• tank outlets and rainwater pipework to be clearly labelled;
• overflow water to discharge to an approved City stormwater collection point;
• appropriate backflow protection at the water meter;
• the tank and supporting structure to comply with the applicable manufacturer or designer requirements; and
• the tank location to remain clear of City water, sewer and stormwater assets and easements.

Property owners should review the current City of Coffs Harbour rainwater tank information and confirm the requirements applying to their property before installation work begins.

Preparing an Above-Ground Poly Tank Base

A Duraplas above-ground poly tank requires a level, stable and uniformly compacted base supporting the complete tank footprint.

Depending on the site, the tank may be installed on:

• 75–100 mm of correctly prepared and retained fine crusher dust of approximately 3 mm aggregate size; or
• a suitable level reinforced concrete slab prepared for the tank and site conditions.

The base should extend beyond the complete footprint of the tank. The overflow should also be connected and directed away from the tank and its base so rainfall and overflow water are managed without eroding the supporting material.

Customers and installers should review the applicable water tank installation guide before preparing the site.

Water Tank Delivery Around Coffs Harbour

Duraplas poly tanks are delivered throughout Coffs Harbour and many surrounding Mid North Coast locations. Freight and delivery arrangements are confirmed according to the tank model, postcode and access conditions.

The property owner controls the access available on the property. Before delivery, customers can help the regional delivery team by providing accurate information about:

• the driveway width and surface;
• gate openings;
• overhead trees, branches, powerlines and structures;
• steep, soft, wet or uneven ground;
• turning and reversing space; and
• the proposed unloading area.

On arrival, the driver assesses the safest and most practical unloading point based on the access made available, the delivery vehicle, the selected tank and the assistance present.

Duraplas delivery vehicles generally require approximately 3 metres of clear width and 5 metres of clear height. A truck-and-trailer combination may measure approximately 19 metres in overall length.

The required number of adult, able-bodied delivery assistants varies according to the tank model. The applicable requirement is displayed on the individual product page and in the poly water tank delivery guide.

Where onward movement or precise final positioning requires additional labour or lifting equipment, the property owner can arrange this separately with an appropriate local contractor.
