How to Design a Home Sewer System
Home sewer systems are needed for those who live in the country or others who want their own home sewer system. But, many are confused on how to begin such a project. There is much to consider such as the size and location of the tank, construction permits, equipment, labor needs and rules to follow. So, before attempting this project, here are some key steps that will help ensure that the job is completed safely and effectively. Does this Spark an idea?
Things You'll Need
- Septic tank
- Construction permit/license
- Measurement for placement of the tank
- Backhoe
- Surveyor's site level or hosepipe filled with water from a datum point
- Sewage Pipes
- Drain rods
- PVC pipe
- Inspection chambers

Plan, evaluate and get permission from your local city authority on where to place the septic tank and where the route of the waste pipes should be. Contact your city hall to be placed in contact with the correct city personnel. Then measure where to place the tank. Be aware that the sewage pipes need to be as straight as possible and ensure that inspection chambers are at short intervals. Also, avoid making the pipe runs too steep. Then, using a backhoe, begin digging for the septic tank. You can either do this yourself or have someone do this job for you. Because it is a physically demanding job, it is advised to have a professional do the job.

Once the hole has been dug, it will be time to put in the septic tank. Be sure that the tank is level with the ground and ensure that the bottom of the tank is surrounded by gravel or rock to keep it level and secure. Then, connect the tank to your home's plumbing system. A PVC pipe is often used for this procedure. Ensure that there are no leaks in the pipes; this could cause pollution and void the system.

Once all of the hookups have been completed, an inspection will be needed. Your next step will be to put in your material, making sure not to damage any pipes that are in the ground. Field pipes often have small holes in them. So, when covering the holes makes sure that the holes are not plugged up.

Fill up the hole around the tank. Be careful not to put a heavy load of dirt on top of the tank because a large load of dirt could crush the tank. Fill the sides of the tank first and while filling in the dirt, carefully tap the dirt into the ground and along the sides of the tank to make sure that the tank is in solid and secure. Be careful not to cover the hatch---the hole on top of the tank. This hole is there in case maintenance is needed.

Fill the tank with water. There are usually guidelines from the manufacturer on how much water to put in. Once the water in the tank has been done, put the tank hatch cover on, put grass seed on the dirt and you're done.

Tips & Warnings
Find out from your local authority the rules that apply to your area. In addition, if in doubt about how your new drainage system is supposed to work, consult the Building Control Department. When designing your sewage system, make sure that all pipe work can be reached by drain rods. This is important in case there is a blockage. It is also necessary that the drain route be as straight as possible. Inspection chambers are also important in case any changes occur in the level or direction of the flow, so that drain rods can be put in easily.
