Septic Tank Cleaning in Carcavelos

About our service in Carcavelos

When a tank in Sassoeiros, Rana or Lombos goes through the summer without trouble and starts to overflow with the first heavy rain, the explanation is rarely how much the household uses. It is parasitic water. It gets in through open joints, through an unsealed cover collecting run-off from the yard, through a downpipe that someone, in good faith, ran into the foul chamber instead of the surface water drain, or through the ground itself when the water table rises and the structure is no longer watertight. The effect is always the same: the tank loses usable capacity, retention time disappears and the soakaway receives liquid it should never see. So here, emptying without investigating is just postponement. Our visit starts with a complete empty, vacuuming the crust and the sludge at the bottom and washing the walls, but the decisive moment comes straight afterwards: with the structure empty and dry we watch whether water comes in when nothing is being used. Whether it does, and where from, changes everything that should happen next. We also check the cover and its frame, because in sand and salt the metal frames corrode quickly and stop seating, and a cover that does not seal is an open door for rain. We leave in writing what we observed, clearly separating what is cleaning from what is repair. Sandy ground has one further consequence on the soakaway side. Soil that drains well in summer can be saturated when the water table rises, and the drainage field stops accepting flow even in good condition. That is why in Carcavelos it makes sense to plan the empty for late autumn, before the heavy rain, rather than waiting for the first sign of an overflow. At houses near the beach, many of them seasonal lets with occupancy concentrated in summer, we deal with whoever manages the property and fit the calendar around it. The waste goes to a licensed treatment plant, with the disposal record handed over.
