Tonttiviemärit

Tonttiviemärit, also known as property drains or lot sewers, are the underground pipes that transport wastewater from a building or property to the main public sewer line or an individual treatment system. These systems are crucial for the hygienic functioning of any building, removing sewage and greywater safely away from the premises.

The ownership and responsibility for the maintenance of tonttiviemärit can vary depending on local regulations and agreements. Typically, the property owner is responsible for the section of the drain that runs from the building to the property boundary. Beyond the property line, the responsibility usually falls to the municipality or a water utility company.

Common issues with tonttiviemärit include blockages, root intrusion, and pipe damage due to age or ground movement. Blockages can be caused by accumulated grease, food waste, or foreign objects. Tree roots seeking water can infiltrate pipes, causing cracks and significant blockages. Older pipes, often made of materials like clay or cast iron, are more susceptible to deterioration and failure.

Regular inspection and maintenance are recommended to prevent costly repairs. Techniques such as CCTV camera inspections can identify problems within the pipes before they become severe. Minor blockages can often be cleared with drain cleaning equipment, while more significant damage might require pipe relining or replacement. Ensuring proper disposal of waste, avoiding pouring grease down drains, and being mindful of nearby tree roots are preventative measures property owners can take.
