MLD
Million litres per day (MLD) is the standard unit for water-supply and sewage-treatment capacity in India: a city of one million at 135 L per head needs 135 MLD.
Symbol: MLD
Quantity: volumetric discharge of rivers, canals and water supply
SI relation: 1 MLD = 0.01157407407407 m³/s (exact)
Derivation: 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
Exact: yes, by definition
Typical uses
- Water treatment and sewage plant capacity
- City water demand (CPHEEO manual)
- AMRUT and smart-city project reports
