A building owner is seeking advice after a ground floor resident installed a new water tank without consent, increasing the total to five tanks for four floors. This, combined with an overflowing tank causing a nuisance, has created a problem. While amicable resolution is advised, options include complaining to the local civic body, as installing such tanks often requires permission due to structural and safety regulations. If discussions fail, reporting to water supply agencies, police, or the municipality is suggested, along with consulting a local lawyer.
