Wastewater & Sewerage
Wastewater & Sewerage sits in the Utilities phase of CityOS — AJG's synthesis of municipal-administration practice across 1,584 tracked cities. Wastewater: collection (sewer network) → conveyance (interceptors) → treatment (STP — primary, secondary, tertiary) → reuse / disposal. India treats only 30% of urban wastewater (CPCB). Singapore reuses 40% via NEWater. Bangalore lake treatment uses STPs to revive Bellandur. Delhi Yamuna restoration is 25-yr saga. Scale: USD 50-200 per connection. Time horizon: 10-20 yr for full coverage. Multilateral coverage: 197 countries × 1,584 cities (T1/T2/T3).

Does Wastewater & Sewerage apply across all 197 countries?
CityOS is multilateral by construction. Frameworks adapt to legal, fiscal, and institutional context — but the structural slices are universal. City-specific applications surface via /os/cityos/country/{country}/.
How does this relate to AJG's broader platform?
CityOS complements TradeOS (operations) and GovOS (rules) by adding the urban-management lens. Cross-OS quadruples — DealOS × TradeOS × GovOS × CityOS — surface strategic + operational + regulatory + spatial views together.
