Termination of tenancy due to hidden fault of the premises

Hi, I only recently rented a small 1 BR in Mirdiff Ghoroob gated community. However, it has been brought to my attention a constant presence of unbearable sewage smell at night time which disturbs my sleep almost every night. I spoke to the property and maintenance office and only realised that the stench is not caused inside the community but by the closeness of the sewage plant treatment.

I am afraid I cannot get used to living in such an environment especially since I suffer from respiratory allergies. I already filed a complaint to the municipality but nobody came to resolve it. I feel I am stuck and doomed because the agency failed to mention this ongoing problem which was unfair and unethical.

Can you please help?

Thank you. Lana
