S1: Baseline

2010: Baseline situation

S2: No intervention

2030: Baseline case; same WWT access percentage as 2010 applied. Only correction for population growth for WWT and MSW

S3:

25% ST

2030: 100% Domestic access, use ST and 25% switch + 100% MSW

25% AT

2030: 100% Domestic access, use AT and 25% switch + 100% MSW

50% ST

2030: 100% Domestic access, use ST and 50% switch + 100% MSW

50% AT

2030: 100% Domestic access, use AT and 50% switch + 100% MSW

75% ST

2030: 100% Domestic access, use ST and 75% switch + 100% MSW

75% AT

S4: Industrial only

2030: Industrial WWT intervention; 100% of big (>1000 m3/d), 90% of medium (500 - 1000 m3/d), 80% small (100 - 500 m3/d), and 75% of very small (<100 m3/d) sized industries apply intervention. Domestic WWT, MSW interventions follow S2

S5: 25% - 75% ST/AT

2030: Combination of scenario 3 and 4

S6a: 25% - 75% RR

2030: Same as S5, using recovery technologies for domestic, industrial effluent recycling and MSW
