Now-a-days technology and science go hand in hand, fertilizing each other by providing explosive synergy. the engineer can choose the appropriate software as per requirement from innumerable variety of software’s of different discipline of civil engineering. Engineer can go through the design process many more times fluently due to more efficient and rigorous results instantly. Moreover Research means not to find or create something new at the door every time, but sometimes research means those things which have not yet been noticed, but they are of equal important. Through this concept, we decided to take this topic. The paper provides an overview of important software’s which are used in the environmental engineering discipline of civil engineering. Due to the software application in engineering field efforts and time for complicated operations and calculations is reduced with efficient results. And there are several environmental software which are existing in market produced by relevant companies which enables user to achieve desired target with principle to improve the natural environment. We contribute the description of these software’s along with their applications in environmental engineering.
