Provision of Staged Onsite Wastewater Treatment Units at Environmental Floors of Multi-storeyed Building with Hydraulic and Structural Feasibility

Abstract

In the present day context of urban areas in Indian climate, looking at the statistics of the operating efficiency of existing mechanically operated water treatment plants run by local governing bodies and even when huge costs are incurred in their maintenance, it is necessitated that an efficient wastewater treatment system suitable in Indian climatic conditions and that too efficient, self-operating with minimum interference and at a low-cost construction, operating and maintenance cost. Decentralized onsite and naturally operating treatment methods are much efficient, cost-effective and feasible for Indian context. In current research, Effective positioning and modeling of the non-mechanised, gravity-based wastewater treatment system is carried out at refuge floor which is coined to be proposed as “environmental floor” for G+32 storeyed residential building. Comparative analytical study for structural and seismic response of both the structures (with and without environmental floors) is performed to check feasibility of the treatment system and quantify the benefits arising from it. It is observed form obtained results that the system can be adopted as an ultimate sustainable solution for wastewater treatment in cities where otherwise a lot of unhygienic conditions prevail if centralized treatment plants are not efficiently working.
