Performance économique des services d’eau potable et d’assainissement en Algérie, cas de Souk-Ahras

Abstract

Résumé Les services d'eau potable et d’assainissement (SEPA) sont confrontés à de nombreuses contraintes de nature institutionnelle, technique et financière. Les attentes des clients et, plus largement, la dimension sociale et environnementale déterminent également l’offre de services. L’objectif de cet article est d’analyser la situation économique en vue de l’amélioration de la performance des SEPA en Algérie, en prenant comme exemple le département de Souk-Ahras. Cette recherche englobe une analyse empirique (technique et financière) de la gestion des SEPA, en analysant des données collectées auprès des services chargés de la gestion des SEPA du département de Souk-Ahras. D’après nos résultats, les tarifs de l’eau potable et de l’assainissement ne couvrent ni les coûts d’exploitation ni les coûts d’investissement de réhabilitation et renouvellement et les grilles tarifaires font bénéficier les gros consommateurs des tarifs « solidarité » pour les premières tranches de facturation.

Analysis of water losses in seven small and medium-sized water distribution networks in the south region of Cameroon (Central Africa)

“…This observation differs from that observed in Algeria, where the loss of earnings is covered by the state in the form of a subsidy (Boukhari and Miras, 2019). Morocco, on the other hand, applies a vast system of equalization between consumption brackets, between trades, and between territories (Lydec, 2016) to seek viable cost recovery in operating expenses and, as far as possible, in investment expenses in the capital (Boukhari and Miras, 2019). Thus, the performance of Camwater would be improved on the condition either of applying the real prices or of systematically taking charge each year of the shortfall linked to the administration of the price of water.…”

“…This creates a shortfall that is not systematically covered by the State of Cameroon in the form of a subsidy. This observation differs from that observed in Algeria, where the loss of earnings is covered by the state in the form of a subsidy (Boukhari and Miras, 2019). Morocco, on the other hand, applies a vast system of equalization between consumption brackets, between trades, and between territories (Lydec, 2016) to seek viable cost recovery in operating expenses and, as far as possible, in investment expenses in the capital (Boukhari and Miras, 2019).…”

Application of the analytical hierarchy process for planning the rehabilitation of water distribution networks

“…The city of Souk-Ahras is supplied from Ain-Dalia dam and Taoura groundwater. The drinking water supply system is composed of a treatment plant, 18 water tanks with a total storage capacity of 33700 m 3 , 55 km of conveyance and 220 km of distribution network (Boukhari & de Miras, 2019). The WDN is composed of different materials (Polyvinyl Chloride (PVC), High-Density Polyethylene (HDPE), cement asbestos (CA), steel and cast iron) and the diameters vary between 63 and 315 mm.…”

Strategic Decision-Making in Sustainable Water Management Using Demand Analysis and the Water Evaluation and Planning Model

“…On average, the cost of producing a cubic meter of conventional water was estimated at around USD 0.70 and that of unconventional water was around USD 1.2. This cost included investment, operating, and maintenance [23,37,38], resulting in more than a USD 168 million loss during the period. These expenses were applied for the whole study when it came to determining the costs of production, leaks, and consumption.…”
