About our plumbing calculators
Where there is no sewer line, a house needs two things underground: a septic tank for the toilets and a soak pit or trench to take the water away. Both are hard to fix once the yard is paved. These calculators size each one from the Indian Standard IS 2470, show every step, and say where the code hands over to your engineer.
