The answer can be yes but ...

The answer can be yes but also not. I start with not. I privilege the individual but especially biological cleansing for three reasons: it gives a sense of responsibility the users of the habitat who will want to have a biological water to sprinkle their vegetable garden it is of financial costs largely lower than that of the collective cleansing financial damping can be done over a small period what is with dimensions social the very interesting one. Yes but. any connection with a collective increases the cost of general treatment of waste waters. it will also increase the cost of the palliative treatments (treatment of muds) If the performance épuratoire of the biological process is of 98%, that of the collective is quasi worthless close to zero certain establishments of the process can be made on the collective to precisely reduce it its costs of infrastructure and management. but that must be done with much reserve. Conclusion the individual cleansing is largely more advantageous with everyone.
