Accroding to LYDEC's statistics, over 50% of Casablancians consume less than 260 litres of water per day and thus pay some USD0.15 per day. At the same time 60% consume less that 4 Kwh per day of electricity, equivilant to USD0.46 per day.

Between 1997 and the end of 2003, LYDEC invested a total of USD479 million to ameliorate its services and distribution network.
