My building has septic tank on its southeast corner.
I have no manhole cover, i.e, upward/eastward/westward/northward access to my septic tank, it's all covered.
I can access it through south wall only. So both input and output (200 mm capped pipe to allow tankers to suck the septic) is on the same side which is south.
I'm trying to make a hole in the south wall, (it's the only way) and take the filtered water to percolation tank so that water can be drained easily and I don't have to pay for septic tanker lorry once in two months.
To take the filtered septic water we can use baffle filter but it's quite vertical in and it would have to be placed inside septic tank and sealed with cement from south side wall.
But after sometime if baffle filter gets clogged, I will have to get rid of the cement coverings from the south wall and take out the filter and clean and keep it inside again.
I'm wondering if I could have some kind of standard inline filter which is outside of the building south wall. It would then be easy for me to clean in case if it gets clogged.
Can someone recommend me a wise idea to deal with my circumstance?
Can I place vertical baffle filter horizontally to the pipe outside of the south wall? Would it work properly?
I mean to say there is a room on the north wall so I can't break the floor and break the north wall of septic tank. Beyond east wall I don't have any land left , on the west there is another room .. so I can't take drain pipe from septic tank there as well. South wall is road facing side so I can take drain pipe from there only. Besides the septic tank inlet is also on the south wall, Ideally I should be having 2 brick walls from south to north inside septic tank so the water than arrives in Northen most chamber will be free from scum or sludge and I should be taking water from here to cess pit. But my septic tank has only one chamber. I want to have a filter outside the south wall which is effective and I should be able to clean the filter once in 6 months.
Here is an excerpt from Government code for areas where there's no Sewage Treatment Plant or Public Sewage line is not there.
A septic tank system is a typical on-site treatment facility that consists of a septic tank and a soak pit and employs two technologies: the first is anaerobic treatment and the second is the methods of letting treated sewage penetrate the ground. It shows stable performance, provided that the water temperature is kept suitable to digestion and the soil has good permeability. Part A: Engineering 9 - 2 CHAPTER 9: ON-SITE SANITATION However, the septic tank reduces BOD up to 50%, so if underground penetration is impossible due to high groundwater levels, rocky strata, non-availability of land for soak-pit, another method must be employed to hygienically treat sewage passing through the septic tank such as anaerobic filter and contact aeration. When this system is applied to an urban area with high population density, care must be taken not to have a negative effect on the surrounding environment.
