Problems by municipality

HI, I AM RAJENDRA FROM OOTY, THE NILGIRIS DISTRICT. MY PROBLEM HERE IS DUE TO IMPROPER MAINTENANCE OF DRAINAGE BY MUNICIPALITY. LET ME EXPLAIN YOU THE SITUATION HERE. THERE S EMPTY LAND WHICH IS 300SQ.FT OF AREA. THIS LAND WAS OWNED BY MY GRANDFATHER AND HE IS NO MORE NOW. ACCORDING TO HIS WILL THE LAND IS TRANSFERED TO ME BY MY GRANDFATHER. BUT HERE THE MUNICIPALITY HAS LAID DRAINAGE THROUGH THIS LAND 10 YEARS AGO WITHOUT ANY PERMISSION FROM US. DUE TO NIL MAINTENANCE THE PIPES OF THE DRAINAGE ARE BROKEN. THE DRAINAGE WASTES OF MORE THAN 60 HOUSES WHICH WAS RUNNING THROUGH THIS DRAINAGE IS NOW SEEPING IN TO THE BUILDING WHICH WE ARE RESIDING AT PRESENT. I HAVE INFORMED SEVERAL TIMES REGARDING THIS TO THE MUNICIPAL AUTHORITIES, NO RESPONSE FROM THEM. SO PLEASE SUGGEST ME A SOLUTION FOR THIS PROBLEM. THANK YOU.
