Thank you. We are very keen to implement the proposed idea on-ground and share our experience and the lessons learned widely.

Firstly, we mobilize the community and secure their buy-in. The work is undertaken in phases - one street at a time. This allows us to organize resources and people's participation without getting into difficult and complex processes. As you may have noticed, these are small-bore, shallow sewer lines and  do not require deep trenching. There is enough scope to review and innovate on the conventional engineering approach for sewerage - this has been our experience. There are several key players involved. We collaborate with various partners and agencies including the city authorities who provide key inputs in the project.  The cluster septic tank (CST) receives the blackwater. We have further refined the DEWAT system and have added a bio-filter (kind of modified 'constructed wetland') at the finishing end of the CST and are recycling the wastewater for gardening/agricultural purpose.

Thanks for the interest in our proposal.
The Centre for Urban and Regional Excellence (CURE) is a development NGO based in Delhi. CURE mobilizes communities to plan and implement innovative water, sanitation and slum upgrading solutions for WATSAN facilities and services and better health practices. Among others, our activities include: provision of sanitation facilities including home based toilets, localized solutions that provide customized household toilet networked to existing trunk infrastructure; decentralized sewage treatment in slum and resettlement colonies which do not have city sewer services. This includes cluster septic tank attached to simplified sewer system connecting home toilets with a decentralized treatment system; water treatment plants as business enterprises for providing safe drinking water, and micro-enterprise based community solid waste management. CURE has been able to leverage state resources for additional infrastructure, facilities and services. CURE has also developed digitized slum maps for Delhi, Agra and two other cities using participatory processes and a mobile‐based application to track and benchmark services for accountability. This has been shared with the urban local bodies for planning, managing and monitoring the provision of municipal services. We have successfully implemented the Cluster Septic Tank (CST) system - planned and constructed through people’s participation in Delhi and Agra. It has three parts: home toilets, a shared septic tank and a Decentralized Waste Water Treatment System (DEWAT). The idea was to provide slum residents a viable and improved alternative to the poorly built and unsafe open toilets or the rudimentary pit latrines with improved home toilet and safe Fecal Sludge Management. Although pit latrine is one of the technologies otherwise proposed as a sanitation solution, it has major issues for densely built up slum settlements including creating hollowness below poorly built residences in close proximity to one another, environmental and groundwater contamination, foul smells, attracts flies and mosquitoes and has other public health issues. As part of providing improved sanitation, we have nurtured community leadership to take ownership, raise community resources, liaison with the sanitation enterprises, oversee construction and operate O&M plans. The immediate impact of the CST have been restoration of the slum dweller's dignity. It has also triggered housing upgrades, as the poor invested in making their temporary homes into permanent ones. A community credit fund has been designed for the poor households to borrow money at low interest rates or act like a bridge fund for the households who were unable to organize their contributions. Donor/CSR funds were also used for constructing the CST.  Since we have presence in Delhi and Agra it will allow us rapid on-ground mobilization. Being already engaged in these cities, we have a fair knowledge about them, the settlements and their forward and backward linkages. This will allow us to quickly identify the area of focus and mobilize the communities. Existing relationship with the concerned authorities and urban local bodies will allow to gather the necessary approvals and coordinate with them. We expect to put together all the logistics and human resources necessary to undertake market assessments within a short timeframe, initiate the research to identify affordable sanitation products and service that can be produced and sold locally and move forward to develop the business model.
Please let us know if additional information is required. We also look forward to your valuable comments and suggestions.
