About Million litres per day

The million litres per day (ML/d or MLD) equals 1000/86400 ≈ 0.011574 m³/s, the standard capacity unit for water-treatment plants, sewage-treatment works, and desalination facilities in the UK, India, and much of the Commonwealth. A small town water-treatment works processes 5-20 ML/d; the Beckton Sewage Treatment Works in London treats ≈700 ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.

About Kilolitres per hour

The kilolitre per hour (kL/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, identical to m³/h. It is used interchangeably with m³/h in Australian, New Zealand, and South African process-engineering practice. Pump datasheets from these markets quote capacity in kL/h; water-meter billing in rural areas uses kL/h for irrigation allocation. 1 kL/h = 1 m³/h = 1 000 L/h.
