Pallavaram Municipality — Water stagnating and bad odour

In front of my house one construction is going on and all the workers are staying there itself. They don’t have toilet facilities and we are getting very bad smell like urine motion etc and water is getting stagnated inside their premises which causes lot of mosquitoes since 20 or more people are taking bath there itself . Kindly look into this issue and resolve it asap. Thankyou
