An example of a combination of solutions can be explained through one of the Ganga states of India, Uttarakhand. The Urban Uttarakhand State Development Agency collaborated with the National Institute of Urban Affairs (NIUA), the Asian Development Bank, the Indian Institute of Technology - Roorkee, and other partners to upgrade the sanitation infrastructure. The study focused on how left-out households in the city and peri-urban areas can coexist with networked sanitation. Interim and intermittent steps are employed to use the current and proposed treatment sites to co-treat faecal sludge and septage (FSS) with sewage in Dehradun, the state capital. A road map for expanding CWIS throughout the state has been proposed to ensure that everyone, predominantly low-income and marginalised, homes and communities, has access to sanitation. Eventually, co-treatment initiatives have assured that low-income communities, commercial establishments and regions with impractical sewer connections have equitable access to improved sanitation services. This indicates that significant investments from states and cities are necessary to overhaul existing urban infrastructure, particularly public sanitation facilities, to ensure universal access and elevate current sanitation standards.
