Municipal Corporation Gurugram [MCG] — Improve the quality of water

I am resident of Laxman Vihar phase 1 Street No.4B, Gurgaon.It has come to the notice that contaminated water is being supplied for the last 7 days. It may not be used for drinking and bathing. Although, I have been trying to submit a complaint for water grievances for 3-4 days on the main website of MCG (mcg.gov.in) but everytime I try to submit the application it shows server error. So, kindly issue directions to the concerned authorities to improve the quality of drinking water immediately.
