Residents of Delta 1 reported foul-smelling water and illnesses including diarrhoea, vomiting and stomach ache. The Greater Noida Authority said Wednesday’s preliminary checks found no evidence of sewage mixing in potable water, but detected a faulty household connection and a pipeline leak. Water samples collected during evening supply hours are being tested; results are awaited. The authority said the damaged pipeline was repaired and the situation was normal.

On Thursday, teams from the Dadha community health centre in Dankaur surveyed 158 households and identified seven residents with health issues: one diarrhoea case, one vomiting case, two fever cases and three cases of cold and cough. Workers distributed 10 ORS packets per household. The Delta 1 RWA said around eight to 10 residents had symptoms lasting four to five days. The sector has six residential blocks and an estimated 20,000 residents; a similar water-contamination issue reportedly affected another block four to five months earlier.

ACEO Sunil Kumar Singh visited the sector. CEO N G Ravi Kumar ordered random water-quality testing citywide, including industrial, commercial, IT and institutional areas. Residents were asked to report water concerns to 9205691408 or 8937024017.
