Useful water treatment information

Water Volume (megalitres) length (m) x width (m) x depth (m) / 1000 = megalitres
  1000 litres = 1 metre x 1 metre x 1 metre
  1 hectare x 1 metre deep = 10 megalitres
   
Area 1 hectare = 100 metres x 100 metres
  1 hectare = 2.47 acres
   
Catchment area and rainfall 1 metre x 1 metre with 1 mm of rain = 1 litre
  1 hectare with 100mm of rain = 1 megalitre
   
Acceptable pH range between 6.5pH to 8.5pH
   
Measurement of concentration 1 mg/lt milligram per litre = 1 ppm part per million
  1 ug/lt - microgram per litre = 1 ppb - part per billion
  1 mg/lt - milligram per litre = 1000ug/lt - microgram per litre
