GHMC — Drainage overflow as Drainage was construction was not completed on time

Drainage in our colony has been overflowing and reaching homes since the construction of new drainage system was started, despite multiple complaints and follows up's the issue hasn't been resolved, the previous drainage system was working fine until they attempted to improve which resulted in even more issues, now the water reaches to our houses and recently the newly half completed drainage cover just blow up because of the force of the water coming from a long way the drainage was stuck as it was not cleaned for quite few days and it has been like that since months and when someone approaches the GHMC office no one responds on it and it has been since many years and no one seems to be fixing it even though we pay taxes, why construct new projects and plan them when you cannot fix the existing one which are becoming a burden day by day, flooding days like Bangalore are coming soon, better move away somewhere out of the country until our countries systems get them fixed, fed up with the government work.
