Study the Feasibility of Use of Grey Water in Concrete

Grey water is potentially less contaminated waste water. Taking scarcity of water into consideration various global agencies are suggesting reuse of grey water for different purposes. Water is one of the major ingredients of concrete and most used material in constructional practices. The grey water available from domestic sources is being used for gardening purpose. As discharge of grey water within the urban area is huge and as good as 60 % of per capita domestic water supply. The possible use of Treated Grey Water for construction is investigated in our study. Samples of grey water are collected from various domestic sources and are subjected to aerobic treatment and then after they are tested to check their suitability for construction purpose. For this help was taken from environmental department in order to do suitable aerobic treatment to the grey water. Thus a method was devised by the environmental department for low cost aerobic treatment of sampled grey water. This becomes the base line for our project work as we received aerobically treated grey water from the environmental department which is further used for our comparisons with underground water. Both of them were found suitable for use in construction purpose. Investigation is then carried out to study the comparative effect of both water samples on the strength of concrete. Concrete cubes of grades M-25 were cast using Under Ground Water (UGW) and Treated Grey Water (TGW) and tested for various tests. The comparative results of tests on concrete were found to be almost similar.
