Reservoir leaking

We are experiencing a water leak from a reservoir across the road from us. We had this issue from 2018 and the reservoir had to be emptied and fixed. The leak started again early September this year 2025. We have been in contact with eThekwini municipality and had visits from 3 contractors and the ward 18 Councilor. But nothing has been done. We are busy with laying paving, and our contractor cannot continue with the paving while the water is still leaking.
