“…Growth of cities in the Global South is currently overwhelming the pace at which centralised wastewater treatment systems can be extended or implemented (Reymond et al, 2020). Conventional wastewater treatment systems are unable, as the only standard solution, to close the sanitation gap and provide sustainable sanitation for the underserved communities of the Global South.…”

“…Despite the numerous market barriers, nature-based technologies such as constructed wetlands, anaerobic baffled reactors and vermifilters have all found their niches in the treatment of domestic or municipal wastewater within small communities, residential buildings and peri-urban areas -and countries such as India and Indonesia have institutionalised the implementation of small-scale wastewater treatment systems for larger buildings (Reymond et al, 2020) and sanitation centres (GoI, 2014). In México, Chile and Venezuela, several nature-based solutions have been developed and commercialised in the absence of regulations for discharge standards from small-scale wastewater treatment systems.…”

“…Many industrial players, ranging from regional to national, already ply the market with prefabricated ‘septic tanks’ but are currently unregulated (barring precast concrete septic tanks). The issue also persists among small-scale sewage treatment plants (SSTP), prescribed by Ministry of Environment, Forests, and Climate Change (MoEFCC), for buildings with a total built-up area above 20,000 square metres ( Reymond et al, 2020 ). Therefore, the regulators at the national and state level should strive to formalise and regulate the prefabricated OSS system and SSTP industries, and facilitate a transition from conventional OSS configurations to more advanced packaged systems ( Fig.…”

Wastewater management predominantly takes the form of On-Site Sanitation (OSS) in low- and lower-middle-income countries (LMICs). In India, households construct and operate OSS systems in the absence of regulatory oversight and seldom in compliance with the national technical standards – posing a risk to water sources and public health. The present paper reviews novel evidence on the quality of these systems from a multi-state survey of 3000 households in India to identify policy and practice interventions for creating sustainable urban sanitation futures. The paper argues for local and national governments to unlock the potential of OSS as a safe and long-term wastewater management solution through (1) re-envisioning the system design to simultaneously meet household and environmental needs, (2) fostering prefabrication of systems as a means to distribute the compliance responsibility optimally, and (3) updating technical standards for facilitating such a paradigm shift.

“…Perhaps the most significant shift is the increased acceptance of non-sewered and decentralized sanitation systems as adequate and longterm options, on par with sewer-based centralized treatment systems (62,63). Evidence of this acceptance is increased incorporation in development agendas and the rapid rise of non-sewered solutions, including fecal sludge management (FSM) (64), container-based sanitation (CBS) (65), and decentralized/small-scale sanitation systems (66).…”

The water, sanitation, and solid waste sectors are closely related and have many interactions between their respective service chains in low-and middle-income countries. Currently, these interactions mostly lead to cross-contamination, and opportunities for co-benefits are seldom realized. This review presents the key advancements within each of these three development sectors in the past two decades. We identify numerous similarities such as decentralization, resource recovery, community involved planning, and digitalization. Despite the potential for synergies and the opportunities to maximize positive interactions, there have been few attempts to break the existing sectoral silos in order to integrate these three service chains. We argue that, with the right enabling environment, an integrated approach to holistically planning and implementing water supply, sanitation, and solid waste management can create positive interactions resulting in co-benefits among complementary development goals. Expected final online publication date for the Annual Review of Environment and Resources, Volume 46 is October 2021.
