WELCOME TO THE WORLD OF SEPTIC TANKS

Domestic septic systems generally fall into three different categories, as stipulated by your local council, depending on soil types, available area for absorption and sensitivity of the area. These are usually confirmed by a geotechnican, in accordance with council guidelines.
  • Septic Tank with absorption trenches.
  • Septic Tank connected to Collection Wells for approved contractor pumpout.
  • An onsite domestic wastewater Treatment System. 
We are agents for ’Bioseptic’ a compact two tank sewage treatment plant, that produces clear odourless water to irrigate your garden. Please refer to the heading Bio-Septic Wastewater Systems below for more information.
We manufacture a wide range of Septic Tanks and Collection Wells, to suit local Council requirements in different areas for different size dwellings. We are fully accredited with “NSW Department of Health” for our whole product range of septic tanks and collection wells. We are also fully licensed for Product Certification as a Quality Assured Product in line with the Australian StandardsMark.
All our septic tanks come standard with baffles, sealed lids, inlet and outlet fittings, caps and access lids. We generally try to work in with your drainage contractor or builder as to excavation timing so we can place the tank directly into the prepared hole, ready for backfilling. The hole should be at least 300mm wider than the tank diameter for ease of craning in. The base should be level and screeded with fine soil or sand, and the depth of the hole should allow for the tank to protrude 100mm higher than the surrounding finished ground level to stop surface water runoff entering the tank.
As our tanks are watertight they can float like concrete boats (after heavy rain) if the hole is not backfilled or the tank is not filled with water. Where ground water is a possibility and flotation may occur, we recommend pouring approximately 1-2m3 of concrete around the base of the tank before backfilling. When backfilling, no sharp rocks or stones should be used so no damage occurs to the tank wall or inlet and outlet pipework. Where pedestrian traffic could fall into the hole, safety barriers should be erected by the builder or contractor around the excavation area, the barrier will be repositioned (if taken down) by us for access/to place the tanks.

As a rough guide our Septic Tank range can be used as follows:
Tank No 1 - Our ‘3050’ - Capacity 3,050 Litres
This is our smallest septic tank and can manage up to a 3 bedroom dwelling.
Tank No 2 - Our ‘3500’ - Capacity 3,500 Litres
This tank can adequately manage a 3 to 4 bedroom domestic dwelling with 2 bathrooms.
Tank No 3 - Our ‘4600’ - Capacity 4,600 Litres
This tank can adequately manage larger dwellings.
Tank No 4 - Our ‘Squat 3550’ - Capacity 3,550 Litres
This is a shallow tank, as the name suggests (930mm) which can be used in areas of solid rock or high water table areas where standard deeper tanks and not suitable.
Absorption Trenches - If approved by local council, length of absorption trench varies between councils. The absorption trench needs to be located below the septic tank so the greywater can flow into it.
Collection Wells - If approved by local council, the greywater flows from the septic tank directly into the collection well (or wells) depending on volume required, Council will advise on minimum holding capacity needed. This greywater is then pumped out on a regular basis by an approved contractor. The installation and guidelines are the same as for septic tanks, the main difference being there is no baffle installed and no outlet.

Our Collection Wells are available in the following sizes:
  • 3,750 Litres
  • 4,750 Litres
  • 5,550 Litres
  • 3,600 Litres (Squat Tank)

BIO-SEPTIC WASTEWATER SYSTEMS

Aussie Precast Products are agents for “BioSeptic” Wastewater Systems. BioSeptic is well-known for providing quality environmental and economical wastewater systems.

THE BIOSEPTIC PROCESS

The BioSeptic system is a compact sewage treatment plant, which treats and recycles wastewater directly on the property. It safely processes all household wastewater and recycles clear odourless water to irrigate the garden.
 
The BioSeptic process begins when all wastewater from the kitchen, toilets, bathrooms and laundry drains into the septic tank. The solid waste settles in the septic tank and naturally occurring anaerobic bacteria slowly break it down.
 
The wastewater overflows into the aeration tank where air is diffused into two separate aeration chambers to create aerobic bacteria. These quick acting bacteria reduce the sewage to carbon dioxide and water. Because aerobic bacteria breathe oxygen there is no odour. Finally, a small amount of chlorine is added to kill any pathogens that have survived the aeration process. The treated water is then suitable to irrigate the garden.

 BIOSEPTIC SYSTEMS

Performa (1500 Litres/Day) – This is our most popular system, and the one most people need with a capacity of 1500 litres per day.

Please contact our office should you need something larger as BioSeptic have larger systems available to suit any need and are used to working with larger/commercial premises.

INGROUND CONCRETE WATER STORAGE TANKS

We manufacture a range of inground concrete water storage tanks up to 10,000 litres capacity. Our tanks are designed to be buried in the ground, which keeps the water cool and the tank out of sight which is especially important in small back yards where space is at a premium and never a problem in fire prone areas. Our water tanks come standard with inspection hatch in the lid and an inlet and outlet.

TANK SPECIFICATIONS

  • Manufactured in 40mpa fibre reinforced concrete with pedestrian lids
  • All tanks made to AS 1546.1:2008 specifications
  • All tanks have 100mm minimum air gap
We generally try to work in with you as to excavation timing so we can place the tank directly into the prepared hole, ready for backfilling. The hole should be at least 300mm wider than the tank diameter for ease of craning in. The base should be level and screeded with at least a 50mm bed of sand and the depth of the hole should allow for the tank to protrude 100mm higher than the surrounding finished ground level to stop surface water runoff entering the tank.

As our tanks are watertight they can float like concrete boats (after heavy rain) if the hole is not backfilled or the tank is not filled with water. Where ground water is a possibility and flotation may occur, we recommend pouring approximately 1-2m3 of concrete around the base of the tank before backfilling. When backfilling, no sharp rocks or stones should be used so no damage occurs to the tank wall or inlet and outlet pipework. 


MAINTENANCE 

Regular maintenance is essential to ensure consistent water quality. Maintenance of the tank and the quality of the water supplied from the tank is the responsibility of the owner. The procedures undertaken should be primarily be to keep all components clean to minimise the risk of water contamination. Therefore the rainwater collection areas inlet screens and first flush devices should be checked regularly for build up of rubbish.

CATTLE GRIDS

We manufacture a range of cattle grids. We deliver and can position directly where it needs to go with our crane truck, if the area has been prepared and we have good site access. The grid comes as a complete unit, ready for installation. They are suitable for on-farm use, e.g. grazing properties where traffic consists of medium tractors, milk tankers, stock floats.

All our grids come standard with:

  • Duragal steel construction (mild steel not recommended in coastal areas)
  • Duragal steel with or without winged sides with infill triangle—needed for stock security
  • Fully engineered, 40mpa high strength steel reinforced, precast concrete base and hold down bolts
Our standard cattle grid is designed to carry 10 ton per axle load limit. 
Our heavy duty cattle grid is designed to carry 14 ton per axle load limit.
cattle grid

Cattle grids come in two sizes: 

3.4m Wide 2.1m Across 500mm Deep (Depth of excavation needed)
4.0m Wide 2.1m Across 500mm Deep (Depth of excavation needed)

Site Preparation

Always install grid slightly above road surface and build up road surface to the grid. This stops water run-off from the road way entering the grid. If possible it is a good idea to drain the grid, this is not possible in some cases. The grids do not need to be installed level if the road way is not level, in other words follow the slope and grade of the existing road way.
