The borewell has been used ever since atleast 3 hrs a week (in parts 30 min at once max), however i observe that sometimes i get a slight brown water.. like small mud particles mixed with water, also it smells slightly oily.
Please advice what should be done to cleanup the water that i get clean and odorless water consistently
