Civil Engineering - Waste Water Engineering - Discussion

@All.

It's crucial to consider factors like population size, per capita water usage, and soil permeability when sizing a septic tank. As mentioned, the CPHEEO guidelines provide a comprehensive approach to these calculations.

To further enhance the efficiency of septic systems, integrating biological solutions can be beneficial. Teamone Biotech offers eco-friendly biofertilizers and microbial products designed to improve the breakdown of organic matter in septic tanks. Their products help in reducing sludge accumulation and enhancing the overall performance of the system.

Implementing such solutions can lead to more sustainable and effective wastewater management practices.

Clarify me, if I am Wrong.

* Effluent is wastewater from the septic tank, it does not include Solid (sludge) and Oil (Scum).

* In rural areas On-site effluent disposal systems may be used in specific soil types and climatic conditions, such as high rainfall or high water table, including evapo-transpiration beds or mounds, sand filters, and soakage wells.

So, Option (A) could be the Correct Answer.

Option D is the right answer. Since the effluent of ST donot contains suspended solid, moreover one cannot be discharged it into an open drain : a provision of soakpit, biological filters and other dispersion trenches are provided so that the remaining putrescible matter can be absorbed into the ground which later on gets filtered. Whereas option C is objectionable to its own paradox content.

Yes, B is the right option, I too agree.

If the effluent of a septic tank is fit for discharge into any open drain then why need soak pit.

So the answer is (b).

Acco. To me, the effluent of the septic tank contains high BOD, odor, suspended impurities, etc.

@Kajol is right (according to SK Garg).

According to me, B is the correct answer.

The answer should be B. Because the effluent of septic tank contains high level of BOD. Thus subsurface irrigation method by absorption trenches, cess pool are used.

Yes, it seems that B is correct.
