Can you replace a fluid pump tank with a septic tank?


I am working on an existing flush toilet that has a septic tank (1500gal) and pump tank (1000); the fluids goes by pressure to the sewer line. The existing toilet needs to be replaced with a new building, my question is can I remove the septic tank and pump tank and replace with a 2000gal septic tank, without the pump tank? or I need to add the pump tank since the existing has….any idea…

I believe you have a STEP (Septic Tank Effluent Pumping) and you need the pump it was built that was for a reason. but just to be sure contact the sewer, water or wastewater department and ask them. Don’t remove it with out getting permission from them. Tom

How do I clean the Fuel pump, filters and tank cleaning on a 95' plymouth neon?

    You appear to have town sewer so I don’t know why you would need a septic tank. Septic tanks provide some basic biological treatment of the sewage before the effluent is discharged usually through trickle beds into the surrounding soil and are required where town sewers are not available. I suspect that originally there was only a septic tank and trickle bed but as development spread town sewer became available so someone installed the additional tank and pump. I’d contact the town engineer and discuss the situation but I don’t see any reason why you could not replace the septic tank and pump tank with one suitably sized pump tank.
