All You Need To Know About Septic System Installation

We have seen a recent spurt in commercial and industrial properties with no access to the public sewage system.   Waste water is one of the biggest pollutant causing health hazards. This waste water has to be treated and handled systematically. The Septic system is an onsite water management and treatment system that is commonly installed in residential and commercial properties.

Waste water management systems are of two types:

1)      Gravity fed

2)      Alternative system that includes aerobic treatment unit

Before you begin the septic system installation, remember to get all the relevant permits as required by your state, city or county.

Preliminary check list

Before you design your onsite septic system, you must consider the size of your land, the depth of the water table during different season, bedrocks, access for maintenance and future replacement options.

A septic tank is usually 12 feet X 8 feet, though it can be of a different size depending upon the number of people. The drain field is usually two lateral 150 feet long and 10 feet apart for most homes.

Only after you have got the clearances, it is worth installing the wastewater management system.

A guide to septic tank installation

1. Embedment material, fittings, hand saw and glue.
2. Place the pipeline from the home/building to the septic tank pit.
3. The flow of wastewater in a gravity fed system must flow downhill. As no mechanical discharge method is used, gravity works to discharge the waste from the tank.
4. Else a pump and a distribution box needs to be set up for a mechanical septic tank system.
5. A concrete aerobic divided tank and perforated pipes that are embedded in the gravel are used in this system.
6. Excavate a large hole to set the concrete tank below the ground level. The lower section of the tank receives all the effluents after a bacterial breakdown which is further broken down before it is drained into the leech field.
7. The upper section of the concrete tank receives all the wastewater and effluents from the house or building
8. The drop in the pipe from the home to the septic tank is calculated as: length of the sewer line from house drain X 1/4th inch drop per foot = drop in pipe level in inches. A little more pipe drop is convenient and practical too
9. Inspect the septic tank for damages. The tank should be water tight so it does not contaminate the drinking water
10. Place the perforated pipe in the drain field with the end cap
11. Get the system inspected by the authorities. Once it is approved, cover up the area with as per the regulation of the health department
12. In case of the alternative septic tank, install a pump chamber after installing the septic tank. This chamber hosts the electric pump which is used to move the effluents from place to place and ultimately to dispose it into the drain field

Drainfield

The most common types of drainfields are rock drainfield system and chamber trench drainfield system. Excavate a trench that contains the distribution system. The trench should be excavated in a soil that is dry and crumbly as wet soil decreases the capacity for the soil to absorb the wastewater.

The trench should have almost no slope, though a 3 inch per 100 feet drop is acceptable. Place gravel at the bottom if required, place the perforated pipe and cover it with loose rocks, which should be absolutely free of fine material. Make sure that the perforated side of the pipes is not facing down.

If you are installing a distribution box, then one more trench will be required. Do remember to check as per the local regulations. The distribution box must lie undisturbed.

Note:

Contact the utility companies before you start digging.

You may set up the septic system, but septic tank field maintenance is very crucial for efficient working of your wastewater management system. Plumbing companies like Dyanamerican offer septic service that includes installation, inspection and maintenance of the septic system.

Availing septic services of professional reduces your repair and replacements costs as well as eliminates the health hazard due to water contamination.

Septic Tank – Construction, Operation And Maintenance

Septic systems are on-site wastewater management systems. These are common in industrial as well as residential properties. This septic system is developed when there is no access to a public sewage system. The waste water from commercial and residential units is collected and transferred into a septic tank where it accumulates. This grey water is treated to decompose the grease and solid settlements after which the effluents are disposed off safely.

Design and introduction to a septic tank

A septic tank is basically a tank that allows solids to settle to the bottom and the scum to float on the top. This is decomposed and eventually leached into the field after the effluents are filtered.

The basic requirement a home owner must understand is:

• The size of the tank depends on the number of bathrooms as every county has its own norms to check the leach field capacity
• The tank must be at a lower level than the house and the leach field lower than the septic tank
• The septic tank must be at least 200 feet away from any water source
• There should be no heavy equipment movement over the pipe connecting the septic tank to the field or the leach field

Septic drain field maintenance

·         Depending on the usage, the tank should be pumped every 1-4 years

·         There should be no heavy objects on the leach field

·         No items should be introduced directly into the septic tank

What not to drain into the septic tank

• Non degradable items like grease, chemicals, cigarette butts, eggshells, bones, napkins
• Do not over use water

Tips

It is advisable to use a trash compactor as it helps to keep disposal use to a minimum.

Why septic system and its maintenance is critical?

• Replacing or repairing the septic system is a very expensive affair.  A new system can cost up to $ 3000 while a routine inspection and pumping will cost around $ 100.
• Improper handling and disposal of wastewater proves to be a health hazard. A failed septic system contaminates the water sources like the well and the ground water as well, which poses a great danger to health when combines with human waste.

Conclusion

A well designed and properly installed septic system cuts out on the cost as well as eliminating the possibility of water contamination which prevents a health hazard. Septic system problems do not show up instantly, it is a slow process which results in complete failure of the system if ignored.
