Septic Tank Cleaning in Alvalade

About our service in Alvalade

Few Lisbon neighbourhoods have aged as coherently as Alvalade, and that applies underground too. The plan called for blocks with shared planted courtyards, and the internal drainage of each group was laid at the same time, with inspection chambers and, in several cases, retention structures that fell out of use once the municipal connection was complete. Seventy years on, the trees shading the backs of Avenida da Igreja and São João de Brito have sent roots towards the permanent damp. The result is familiar: slow drainage on the lower floors, a smell in the courtyard on warm days and, sometimes, a cover that no longer opens because it ended up under soil and root. What we do starts with locating. We compare the original layout with what is visible on the ground, probe for the cover where it has vanished under the lawn and confirm what the chamber receives before any suction. Then we empty it with the tanker and wash the walls, which usually reveals the real cause: a root through a pipe joint, an inlet no longer in use, a badly sealed opening from an old branch. We say what we see, even when that means admitting that cleaning alone will not do it and that the answer involves cutting roots or replacing a length of pipe. The third aspect is human. Alvalade has a settled, older resident population, in buildings where decisions take time because they involve people who have lived there for decades. We work well in that setting provided one thing is in place: someone who authorises the work and opens up the courtyard. We agree the time in advance, arrive identified, avoid noise first thing in the morning and leave the courtyard as we found it, with no loose soil trodden across the pavement. The waste travels in our own vehicle to a licensed treatment plant and the disposal record is available for the building's files.
