We really need now to speed up for both septic .
For the septic (which is actually a biochemical tank, not a simple septic) , I still need to know :
• If it can take black and grey water
• Where is the sludge store inside the tank ?
• If we need a prepond. But from today, we decided that we will use a pre-pond (small tank before septic) to collect underground the sewage water, then we will need a sub merged pump (for black water) that will send the sewage water to the septic that we will locate overground (easier to sset up, connect and maintain)
