Law against neighbour irresponsible behaviour

Hello sir / madam Their is leakage of water from neighbour house..the same leaked water is passing through our gate and whole area is become a dranage kind with faul smell and moaquitos around as well and whole of the area been green in color because of fungus. We have proved several times to neighbours who happen to be tentants staying. And they happen to tell their owner about the same whereas their owner is not ready to taken any action and claims this water leakage is from our house with no proof with him. To justify my side i have following points like - * previous day night i happen to took bath around 9.30pm and checked their was no leakage. * next day morning around 4 am my husbund has returned from chennai and he took bath at 4.30 am still no leakage * also we had put clothes in washing machine at 5.00 am even aftér the washing machine stopped their was no leakage. * after 7.30 am to 9.00 am only their was leakage of soap water wereas none of us from house had taken bath ..my father in law takes bath aroud 10 am We have continuously clarified these points and the neighbours owner doent want to agree and been very irresponsible..i have kid at home and unable to even keep the main door open because of faul smell and mosquitos... With no option, need to understand if their is any law to file a case futher against this issue...please advise. Please email me....
