Abstract
Mumbai is the financial, commercial and entertainment capital of India, facing bigger challenges in accommodating its over growing population day by day. The Mumbai City has population of 18.4 million over its 634 km2 area, ie. Almost 350 ft2/person. This enormous rise in population density has restricted the development to expand vertically. This also, results in growth of major slums, which is almost 62% of the population dwelling in slums. Subsequently, the authorities is in need of a large scaled Slum Sanitation Program, which utilize the scarcely available land for construction of Community Toilet Blocks with involvement of NGO’s and social experts like Tata Institute of Social Sciences. In this paper an attempt has been made to rehabilitate a G+2 public Toilet Block constructed in very densely populated slum along the hill side of Eastern Mumbai Suburb. The structure is recently constructed on the top of 9 m high retaining wall which has faced an incident of failure of old rubble retaining wall, during course of heavy rains at a rate 100mm in an hour. It caused the soil below the foundation to slip off partially. It was indeed a challenging job to retrofit and stabilize the Structure with best possible technology in the critical site as well as climatic conditions. The short-term as well as long term solution was recommended with the limitation of time and the availability of space. The paper presents, the approach to achieve, durable, sustainable - Structural and Geotechnical Solutions, for Rehabilitating the said (G+2) Structure and the 9m high retaining wall.
