What Is a Septic Tank Emergency?

Septic Tank Emergency

A septic tank is one of the most out of sight and out of mind elements of your home. They are typically installed underground in your backyard, but are often located in the front if you don’t have enough space in the back. Since they are not seen, you probably don’t even think about them. Some people don’t realise they have a septic tank. A septic tank is different from a municipal line because when you flush your toilets or run water through your sinks, the waste goes into a tank instead of to a sewage treatment facility. Once in the septic tank, the waste separates into three distinct layers.

Three Layers

A layer of scum rises to the top; this consists of oils, fats, and anything else that floats. The bottom layer is a layer of sludge, which is the solid materials. The middle layer is water. There is a drain pipe that is installed into the septic tank. The drain pipe is designed to reach below the layer of scum on top but not so far that it picks up the sludge on the bottom. The water from the middle will be drained out of the septic tank and into a drainfield. The drainfield is an area under the garden which is filled with a filtration material such as sand. The water from the septic tank is filtered through the drain field. It is also normally treated with bacteria that composts it. Then, the nutrient rich water is released into your garden. That’s why the area around your septic tank often has the greenest grass. A septic tank emergency happens when you neglect your septic tank cleaning in King’s Lynn.

Cleaning the Tank

The average person produces about 100 gallons of waste every year. Therefore, a family of four will produce 400 gallons of waste a year, and therefore, they’ll need to clean their 1500 gallon septic tank every four years or so. If that does not happen, the layer of sludge will often rise up and block the drain valve. In other cases, the layer of scum on top will become thick enough that it blocks the inflow pipe. Either way, you’ll end up with blocked pipes and a septic tank emergency.

If the inflow valve is blocked, the sewage will begin to back up into your house. You’ll probably first notice that your fixtures are not draining as fast as they should. You might also smell a strong odour of sewage near your drains.

If the drain pipe is blocked, the middle layer of water will not effectively drain out of the septic tank, which means the tank will fill up prematurely. Many different things can happen when a tank fills up prematurely, one of the most common being that you will begin to see the sewage rising up in your garden. You might not even know what it is at first. If you see water puddling up in your garden when it has not been raining, it is likely that you have septic tank issues.
