VIRUDHUNAGAR: Residents of ward 21 of Virudhunagar town have complained of sewage mixing with drinking water supplied through pipeline. The residents fumed that drinking water was being supplied only two times a month in the town. And even that little water was not usable for any purpose, a resident said. Stating that chikungunya broke out in the area few months back, they fear of falling victim to diarrhoea due to water contamination. The problem was prevalent in Marimuthu lane, Ramasamy lane, Andichiamman lane, Poosari lane and Kuppaiah lane, they said. The ward councillor, N. Thangapandiammal, said she had complained about the issue to the administration two months back. But no concrete action has been taken so far.
