Ghaziabad Nagar Nigam — Overflow of sewage

I am the resident of sector -9, mawai, Vijay nagar ghaziabad. I am facing the issue of the overflow of severage for last 20 days.I already complain to nagar nigam and the parashad of the ward 58.but i I did not get any resolution yet.the concern team visit at the location and see the issue and said they need the pressure pump vehicles but due to narrow road it's not comes in and the other option they need to construct the new severage.but they did not start the work in any of the option. I request to nigam please get it resolved as soon as possible
