There are numerous  types and sizes of septic tanks ranging in size, shape and construction materials.

Our basic charge is the same for average septics but the disposal charge {this is set by SA Water} will vary depending on the size of the septic.

Most tanks are made of a single cylindrical tank. They usually have a baffle 1/2 to 2/3 the way down the length of the tank with a couple of small holes half way up the baffle wall. If you are on a STED scheme the water then goes through to the sewer. If you are not on a STED scheme the water usually goes through to a soakage pit down hill a little or through a reuse system. When the septic is left to long between cleans sludge can flow into the soakage pit, lining it and vastly reducing the amount of liquid that can soak away. This problem usually comes to light towards the end of winter when you end up with sewage coming out of inspection pipes or the top of  the septic. If you have a reuse system the sludge can block sand filters with some systems and build sludge up around pumps in other systems.

 What do they look like ?

Concrete tanks

Small septics are generally 1750 lt and usually consists of a cylindrical  tank with one concrete lid on top. Typically they will look like this.

1750 septic broken lifters

1750 lt septic with broken lifting rods

 

Old square tanks are very common around older properties and are usually {not always} around 2000 lt.

They are usually around 2.5 to 3 mt long and have 3 or 4 very thick large concrete lids on top. I suggest you do not walk on top of these lids as they are not as strong as they look. If you are shifting a lid for pump out I suggest that the 3rd lid  away from the entrance is the best bet as you can often get to both sides of the baffle with one lid removed.

The most common tanks are 3000 lt and consist of a cylindrical tank approximately 2m long with two concrete lids, with wires for lifting, covering most of the length of the tank.

4000 lt tanks with 3 small lids with {swift lifts} are also common in this area and are approx 2 mt long also.

5000 lt tanks are uncommon but are sometimes found in areas of high usage and look almost identical to the 3000 lt tanks.

Biocycle

These are a recycle system that allows you to reuse the grey water for gardens etc. They are a little more to clean out due to the high volume of water in the units and the lack of access to clean out the sludge. Common around this area they are a round concrete tank with a blower and pump mounted on top. Health department recommend cleaning every 4 years.

Polly Tanks

Mostly 3000 lt

There are several types of polly septics around and they do have an issue in cleaning buried septics as some have stamped on them to only half empty while others ask you to half fill them again if they are buried.

The most common type has two lids that have 4 small luggs around lid. These lids clip over the openings and need a lot of room around them to be able to get a crowbar under the luggs.

There are a couple of other polly septics around that have a single lid which is often screwed down to the top.

 

What they don’t look like

Although not impossible for these to be the access point for your septic, these inspection lids usually cover inspection pipes. There may be one either end of your septic tank or they may be in the inlet or outlet line to the tank.

    Hi there,
    Could you tell me the price of pumping out an Ozzi Clean septic tank please. At the moment it is situated in the ground at Charlton Gully. We just need it pumped out around maybe mid to end of February so that the tank can be dug up & relocated to Cockatoo Rd Boston, not far from the Golf Course on Flinders Hwy. It’s not blocked or anyhing…just needs relocating.

    I look forward to your reply with a rough quote. I would assume at a later date you would like to see it before giving a fixed quote.

    Many thanks,
    Marion
