Legal remedy for damage to irrigation waterline by neighbour

The owner of my adjoining agricultural land had converted his farmland to residential plots and has sold them. As we were using a common irrigation pipeline half of which is buried and the remaining half is an open 3' canal, my neighboring farmland owner agreed not to touch or modify the irrigation water line. Recently one of the purchasers of the plot commenced escavation activity for their house construction and damaged the underground pipeline and a small distribution tank. This was done even after my repeated plea not to carry out the escavation as it might damage the buried water line. However they did not listen and finally damaged the pipeline and destroyed the distribution tank. Now I'm put to hardship as I cannot irrigate my farm. I took this case with police and they had asked the site owner to fix the pipeline and water canal. But the owner of the site is in no mood to accept it. I seek your advice on how to proceed on this. Should I lodge a criminal conspiracy complaint?
