How is WWT planned for Low Middle income countries?
Countries must build wastewater infrastructure to meet the United Nations' Sustainable Development Goals, but low and middle-income countries face numerous challenges. Parts of their populations are still without sewers, and some of the sewage that is collected is still discharged into nearby bodies of water.
Low and middle-income countries must follow:
1. Planning horizons of 20 to 30 years that take population projections into account. In the event of inaccuracies, phased project implementation allows for forecast adjustments.
2. Differences in sewage characteristics from one region to the next. Flows must be accurately assessed, and literature tailored should be consulted.
3. Selecting between centralized and decentralized care. The population, topography, and network layout should all be considered. The decision to discharge or reuse effluent should be made with Environmental laws and impacts in mind.
4. Sludge and biogas destination and treatment planning. Each site should have its own set of solutions.
5. Creating and sustaining public trust. It is critical to involve the surrounding neighborhoods and treat residents as partners from the start.
6. Because most bottlenecks are managerial rather than technical, success is more likely when management concerns are addressed early on.
The reasons for low quality treatments
1: Inadequate WWTP functionality can be caused by poor design and inappropriate technology choices, but it can also be caused by insufficient operations and maintenance (O&M). Inadequate technology or design can make O&M more difficult to perform, which can lead to the latter.
2: Critical underlying causes are institutional weaknesses and constraints to managing WWTPs sustainably, such as low political priority, a lack of recurring finance for O&M, and insufficient knowledge, skills, and systems for O&M.
3: The default approach of donors is to fund only facility construction and rehabilitation, which is insufficient to address existing institutional constraints and weaknesses. These are often overlooked when creating plans and designs (often by foreign consultants).
A response is required!
Existing efforts to address these issues, such as developing human resource capacity, establishing water operator partnerships (WOPs), and strengthening regulators, must be strengthened and mainstreamed. Furthermore, Governments and donors must approach urban sanitation in a more holistic manner that does not consider sewered centralized sanitation to be the only option.
Technology selection for WWTPs should be based on a number of factors, with a primary focus on O&M and sustainability. Strengthening the capacity of local and municipal institutions, as well as wider institutional reform, is critical for creating a more enabling environment.
