Abstract:- In India the rivers are getting polluted due to mixing of untreated wastewater into the river directly. Due to mixing of untreated wastewater and the non-availability of proper treatment system in villages it is necessary to reuse the treated wastewater for farming and other application and it is necessary to avoid the direct discharging of untreated wastewater into the rivers. The wastewater samples were collected from nalahs, river upstream and downstream for analyzing and comparing the quality with respect to pH, COD, BOD, TDS, TSS and total coliform. Based on the analysis report it has been observed that, due to directly mixing of untreated wastewater from village into the Dudhganga river, the concentration of COD and BOD in downstream is observed to be at increased level with respect to upstream concentration. An integrated approach is needed to manage the water and wastewater treatment so that water supply is kept clean and wastewater is recycled for beneficial use in agriculture with the use of low-cost treatment like in-situ nallah treatment with use of elephant grass and canna indica. Adopting such in-situ treatment with using natural resources is important to make the Zero Liquid Discharge villages in Maharashtra as well as in India to conserve the rivers.
Keywords: Sewage water treatment, River pollution, Low-cost treatment, Village wastewater management, In-situ treatment.
1. INTRODUCTION The state of Maharashtra which is located in the western region of India, is characterized by its diverse landscapes, rich cultural heritage, and rapid urbanization. Within this dynamic milieu, the management of wastewater poses a significant challenge, particularly in rural areas where infrastructure and resources are often limited. One such region grappling with wastewater management issues is the village of Siddhanerli situated in the district of Kolhapur. The objective of this research paper is to comprehensively assess the wastewater management practices in Siddhanerli, evaluate the repercussions of untreated wastewater disposal into the Dudhganga river, and propose viable, low-cost treatment methods tailored to the community's needs. By undertaking this study, aimed to shed light on the critical issue of wastewater management at the grassroots level and provide actionable insights for sustainable solutions. The review of existing wastewater management practices in Siddhanerli will serve as a foundational step in understanding the current scenario. This analysis will encompass an examination of the infrastructure, policies, and community practices related to wastewater disposal and treatment. Additionally, it will highlight any gaps or inefficiencies in the existing wastewater management system that contribute to environmental degradation and public health risks. Subsequently, the evaluation of the impact of untreated wastewater disposal into the river will illuminate the ecological and social consequences of this practice. By assessing water quality parameters, ecological health indicators, and community perceptions, we aim to quantify the extent of pollution and its ramifications on both the environment and human wellbeing. Drawing upon the findings from the initial assessments, the research will then focus on identifying suitable lowcost wastewater treatment methods tailored to the specific needs and constraints of the community. Emphasizing simplicity, affordability, and effectiveness, these methods will be evaluated based on their technical feasibility, scalability, and socio-economic implications. Finally, the research endeavors to facilitate coordination with the gram panchayat, the local governing body, for the effective implementation of the wastewater management scheme. Through stakeholder engagement, capacity building, and participatory decision-making processes, we aim to foster community ownership and ensure the long-term sustainability of the proposed interventions. In summation, this research paper seeks to address the multifaceted challenges of wastewater management in the rural context of Maharashtra, with a specific focus on Siddhanerli village located in Kolhapur district. By undertaking a holistic approach encompassing assessment, evaluation, identification, preparation, and coordination, we aspire to contribute towards the realization of a cleaner, healthier, and more sustainable environment for present and future generations.
