Domestic water must still be boiled in the area of ​​Etelä-Tammelan Vesihuolto Oy.

The boil water advisory issued in the Etelä-Tammela water supply area due to a burst pipe continues as a precautionary measure. The boil water advisory was issued yesterday, August 27, 2025. All drinking water and water used for cooking must be boiled for at least five minutes in the Etelä-Tammelan Vesihuolto Oy area.

Determination of intestinal bacteria is in progress

The South Häme Environmental Health Department has taken water samples from the area's water supply network. No Escherichia coli or coliform bacteria, indicating water contamination, were found in the water samples taken yesterday, August 27, 2025. The determination of enterococcal bacteria of intestinal origin is in progress, which is why the cooking advice continues. New water samples have been taken today, Thursday, August 28.

Due to pressure fluctuations, water discoloration has been observed widely in different parts of the water supply network. Pressure fluctuations have also affected the network outside the boil-water advisory area, at least in the vicinity of Papinsillantie and in Kydö. Water should be run abundantly until the water becomes clear. If there is no water or the water does not become clear after abundant running, the resident should contact the South Tammela water supply. The boil-water advisory is in effect until further notice. Water can be used normally for washing, washing dishes and doing laundry if the water is clear.

You can check the cooking advice area on the map found on the Tammela municipality website (pdf)..

The new bulletin will be published on Friday, August 29, 2025.
