Septic tanks are used in areas where waste water treatment is
not available. Usually in rural areas, septic tanks are installed, which use
two types of systems. They are gravity fed or aerobic treatment units that are
the alternate systems.
Installation of the gravity fed system
1. Assemble the
backhoe tractor, trencher, shovel, dummy level rod, PVC pipe, glue, fittings,
hand saw, coarse file and embedment material
2. Obtain required
permits that include a test report to determine the size and type of drainage.
This test is usually done by the local health inspector and is governed by the
local regulations
3. Plan the flow
to go downhill so no mechanical device is used to discharge the water.
You will need a concrete aerobic divided tank and perforated pipe
embedded
4. Excavate a
large hole to set the tank which comes in two pieces. One section receives the
effluent where it is broken down by bacterial activity while the second section
breaks it down further before it flows into the field
5. Hold the pipe
steady by embedding the pipe in gravel. The pipe should have no slope
6. After
inspection, cover the tank as per the health regulations in your area
Installation of alternate septic system
1. Excavate the
ground to set up the pump chamber which moves the effluent
2. Get a licensed
electrician to install the electrical part
3. Draw the layout
of all the sewers, locations and depth of all the tanks so as to route the
effluent lines. Get the septic tank plan approved by the local health authority
4. After inspection,
cover the pressurized lines
Tips and tricks
·
Aerobic bacteria have to be added periodically
·
Every step of installation requires inspection and approval by
the health department
·
Either you can use sand or gravel to embed the perforated pipe
as the pipe moves and can cause damage
·
Ensure that the perforated pipe is not turned downwards and put
the end cap on each line else water may enter the pipe and overflow from the
leech holes
·
Check with the local authorities if you can use this water for
irrigation or other purposes
