Septic Tank Emptying Costs – Read This and Save Money

If you have a septic tank or a sewage treatment plant, you will need to get it emptied regularly. This will prevent septic tank problems occurring.

Septic tank emptying costs

Septic tank emptying intervals vary depending on the size of the septic tank. As a rule, a septic tank should be emptied when the sludge level is approximately 25% of the depth in the sludge chamber. You can check to see when your septic tank needs to be emptied by checking the sludge level yourself with a dipping stick. Alternatively, you can get your local septic tank emptying company to check the sludge level.

The septic tank emptying cost will vary depending on the company you use. By using a local company for your septic tank emptying it will typically keep your costs low. It is important to always use a licensed waste collection company for your septic tank emptying. Using an unlicensed company can result in significant fines.

It is important to note that septic tank emptying after heavy rainfall will require you to immediately refill your septic tank with water. Otherwise, an empty tank can get damaged by the pressure from the surrounding wet soil or the water table. By filling it with water again immediately, the water in the tank counteracts this groundwater/soil pressure. So, septic tank emptying after rainfall is OK, but just be sure to fill with water.

Septic tank sizing

Your minimum septic tank size is determined by Environment Agency design criteria.

The septic tank sizing calculator is as follows;

Septic tank size = [P x 150L] + 2000L

P = the number of people in the house.

So, for a 6 person house the septic tank sizing calculator is as follows;

6 persons x 150L + 2000L = 2900L

This is the minimum size of septic tank you should use.

Septic tank emptying will need to be more frequent for a small septic tank when compared to a large septic tank. The septic tank emptying intervals do not change whether you have a plastic septic tank or a concrete septic tank.

A septic tank is an effective way of dealing with your sewage and wastewater in an area with no mains drainage network. A septic tank can deal with all sewage generated from within the four walls of the house. Only roof water or storm water should be prevented from entering the septic tank.

Fats, oils and grease

Many types of waste like fats oils and grease [FOG] should also be prevented from entering your septic tank. Many septic tank emptying companies will not want to empty your septic tank if it is full of grease, as they may not have a license to collect greasy water. This can result in an increase in your septic tank emptying costs. So, it is important to always have a grease trap through which your kitchen wastewater should pass.

After your septic tank emptying, always check to make sure the lids of your septic tank are secure. As a septic tank without a good lid can pose a danger. It is recommended that your septic tank should be located in a fenced off area.

Included in your septic tank emptying cost is often a report of a septic tank inspection. Septic tank emptying after work and reporting can include an assessment of your tank. This can include confirmation that the baffle wall is in place and intact, confirmation that all T-pieces are in place and confirmation that there is no water ingress along joints.

Why empty your septic tank

Emptying your septic tank is an essential part of your home maintenance work. While your septic tank is underground and out of sight, failure to empty your septic tank regularly can result in major issues. These include pollution of neighbouring lands, backed up sewers preventing you from using the toilets, and soakaways or percolation areas becoming totally blocked with sludge. So, while a septic tank emptying cost is not cheap, the possible issues that can be caused by a failing septic tank are serious. Septic tank replacement costs far outweigh those of getting your septic tank emptied.

The final point to note is that septic tank emptying and sewage treatment plant emptying must be done by a professional. This is due to the health and safety risks involved with working around septic tanks. You should know the make and model of your septic tank or sewage treatment plant. Always keep a copy of the manual at home. This manual should be shown to your septic tank emptying company so that they can read the manufacturers recommendations to make sure no damage is done during septic tank emptying.
