A drainage network map helps delineate the different watersheds within a region, which play a significant role in both sewer and non-sewer zoning for any large town. Furthermore, watershed zones have significant applications in grey water management using an i...

Data Requirements Waterbodies/ Rivers Building footprint

Stepwise Process Flow Details Step 1: Overlay the Data Layers Start by overlaying the water bodies, rivers, and building data layers on your map in the QGIS software. This involves using the 'Add Layer’ feature to import the necessary layers into your ma...

Areas in proximity to water tend to have a heightened risk of untreated wastewater encroaching into nearby water bodies, which can have significant public health and environmental ramifications. Identifying such settlements can guide the selection of safe cont...

Data Requirements Building footprint with Typology Slum boundary

Step 1: Determine the Building Typology The first step involves examining the building data you've collected. If the data includes information on building typology, you can use this to identify all buildings with 'kutcha' construction - a term used in Sou...

Settlements identified as economically vulnerable are given priority when designing and implementing sanitation interventions across the sanitation value chain. These settlements can also be overlaid with other environmental and climate risk outputs to identif...

Data Requirements 1. Building with type of use and number of floors

Step 1: Gather Building Data The initial step in the process involves gathering the relevant building data. This includes a building-level land-use map which details the characteristics of each building such as its type (e.g., residential, institutional),...

Buildings that produce significant wastewater should be prioritized for on-site treatment, particularly if they're near water-sensitive areas, given the considerable environmental and health risks. Recognizing these bulk generators can guide us in two ways. Fo...

Data Requirements Output map of settlement near to water bodies, Output map of settlement with waterlogged and flood prone risk Output map of hard-to-reach settlement area Output map of bulk wastewater generator building

Step 1: Gather Spatial Layers of Containment Risk This initial step involves the collection of spatial layers that map various types of containment risks. These might include data on settlements near water bodies, waterlogged areas, flood-prone regions, hard...

Location-based information can assist in tracking the evolution of improved containment systems over time. Such data also offers crucial insights for shaping city sanitation regulations, thereby facilitating an understanding of overall containment improvement ...

Data Requirements Major commercial and institutional land uses Network Dataset using the road network layer Location of public toilets with number of seats

Step 1: Assess the Walkability Factor For this process, a network analysis of the study region is necessary. This involves the creation of a network dataset. Step 2: Create a Network Dataset The road network shapefile must be clean and free from any...

Implementing and adapting these recommendations would contribute to an adequate distribution and coverage of public toilet services throughout the city. A primary focus is on achieving a balanced gender distribution of water closets (WCs). Common observations ...

Data Requirements Location of existing and proposed FSTPs Network dataset using the road network layer

Step 1: Load the Network Dataset Load the road network shapefile in QGIS, which you created earlier as a network dataset. Step 2: Add FSTP Locations Add the locations of the existing and proposed FSTPs as input data for the network analysis. St...

This type of analysis aids in assessing the locational suitability of both existing and proposed Faecal Sludge Treatment Plant (FSTP) sites. Based on the results, areas outside of smooth travel distances might consider the possibility of implementing transfer ...
