Tips to be a Successful Septic Tank Owner
The average household septic tank system should be inspected at least every three years by a professional septic tank company. Residential septic tanks are typically pumped every three to five years.
Four major factors influence the frequency of septic tank pumping:
•Size of Household
•Total wastewater generated
•Volume of solids in wastewater
•Size of septic tank
What happens when a septic tank company is coming to inspect your septic tank:
When you call a Union City septic tank company, they will inspect for leaks and examine the scum and sludge layers in your septic tank.
It is important to keep maintenance records on the work performed on your septic tank system.
Your septic tank includes a T-shaped outlet which prevents sludge and scum from leaving the septic tank and traveling to the drainfield area. If the bottom of the scum layer is within six inches of the bottom of the outlet, or if the top of the sludge layer is within 12 inches of the outlet, your septic tank needs to be pumped.
To keep track of when to pump out your tank, keep a diary of the sludge and scum levels found by the septic professional.
The licensed plumbing company should note repairs completed and the septic tank condition in your system’s service report. If other repairs are recommended, hire a Union City professional septic tank company soon.
Septic Pumping Is Really A Fact Of Life
Septic tanks are designed to hold human biological waste material right until bacteria break it down into gases, solids and water. The tank itself is usually made from concrete, but can also be built from non-degradable materials. It is very important to take proper care and maintain your septic system so that they work properly at all times.
Septic Systems And Their Problems
Some of the most common problems in septic systems are the following:
• Use Of Strong Chemicals: Toxic chemicals such as gasoline, motor oil, solvents, pesticides and other chemical products that are put into the drain harm the nearby soil, making it unfit for the growth of plants. They also destroy the bacteria needed to break down the waste in the tank.
• Flushing Down Non-Biodegradable Items: These items never break down naturally and only fill up space. It only ups the liquid levels in the tank and causes clogging.
• Too Much Water In The Tank: When there is too much water in the tank, the waste does not get a chance to break down, and this eventually blocks the distribution tubes.
• Use Of Too Much Detergent: Overuse of detergents cause a lot of problems with your pipes and tanks as the excess residue can stick to the sides and corrode the pipes.
These are just some of the common problems and preventive measures that you need to keep in mind when it comes to your septic tanks.
Septic Tanks - Ensuring Water Quality
Septic Tank Sewage Treatment Systems
These provide a very crude method of treating sewage for properties which are not connected to mains drainage. Many septic tank systems throughout the world are never maintained and so do not work properly and pollution control laws exist to try to limit the amount of environmental and health risks they cause. These laws are getting tighter, and minimum standards have been put in place for new or replacement septic systems. In many cases you will need to install a sewage treatment plant system instead. Always get the sewage system checked by a wastewater system expert prior to purchasing a property in order to prevent a pollution problem.
Types of Septic Tank Systems Available
There are various types of septic tank systems. They consist of an underground septic tank in differing shapes and sizes, which then connects to a secondary soil treatment system, usually a land drainage system in the form of a soakaway or drainfield, or a mound soakaway.
How a Septic Tank works
Raw sewage and wastewater from baths, kitchens, etc. discharges into the tank, where the solids are separated from the liquid waste. Fats and oils float to the top of the tank and form a crust layer. Faeces and food scraps sink to the bottom of the tank and form a sludge layer. Anaerobic bacteria which are natural colonisers in the tank "digest" this sludge by up to 70%.
The dirty septic water flows out of the tank to a soakaway or drainfield. Baffles or 'T' pipes in the tank hold back the floating crust and prevent it from entering the outlet of the tank. In order that the sludge and crust layers do not become too deep, septic tanks should be emptied annually. This also prevents a higher and higher concentration of suspended solids washing out into the soakaway. Solids can block the air spaces in the soil drainage system, creating a drainage problem and the septic tank effluent will not be able to soak away or be treated by the natural soil bacteria.
Variations in Septic Tank systems
Traditional septic tanks comprise of two rectangular chambers: the first one being 2/3 of the whole and the second 1/3, usually built in brick or concrete. Strict design rules are in place and septic tanks must be designed in accordance with BS 6297 1983. The inlet pipe into the first chamber ends in a 'T' pipe which travels down the at least 450mm (18") below top water level (TWL), and the chamber must be a minimum of 1500mm (5'-0") deep from TWL. This first stage chamber is usually twice as long as it is wide. The pipe from the first chamber into the second chamber consists of an 'H' pipe and the bottom of the pipe is a min. of 300mm (12") below TWL in the first chamber and 450mm (18") below top water level (TWL) when it enters the second chamber.This second stage chamber is usually square. The outlet pipe from the second chamber of the tank also consists of a 'T' pipe with the bottom of the pipe 300mm (12") below TWL.
Site Conditions and Installation
Most sites in the UK are not suitable for septic tank systems. Either the soil contains too much clay or is too porous, or the winter water table or bedrock is too near the surface. If the soil is clay, then it will not soak the septic effluent away and if it is too coarse it will not retain the effluent long enough for treatment. You could consider a non-electric sewage treatment plant instead. Sometimes, it is possible to adapt a septic system to suit a basically unsuitable site, but this requires careful planning and design by an expert. As a general rule, if the site has either insufficient soil depth, or the wrong type of soil, it is not suitable for a septic system. Always contact your Building Inspector before deciding on a septic system.
The size of a septic system, both the tank and the soakaway area, is determined by the number of bedrooms in the house and porosity of the soakaway soil. A septic system cannot work if it is overloaded, so always bear in mind any plans you may have for extending the property before you decide on the size of the septic system. Increasing the size later results in a ruined garden.
Finally, always check with the Environment Agency and you local Building Control before deciding on a septic system in [post_name]. They will have a very good idea as to whether it is likely to work in your area and could save you thousands of pounds in replacing an unsuitable septic installation.
