| dc.description.abstract | The scarcity of conventional water resources represents for Algeria, because of its
Mediterranean climate arid to semi-arid, a major concern. The global water potential of
Algeria does not exceed 13.2 billion m3 of water, which offers an annual volume of 412
m3 to each citizen. Considering the vulnerability of available water resources to the
impact of climate change, population growth as well as socio-economic factors, a
situation of severe water scarcity occurs, which hinders the development of the country.
This project seeks to study the feasibility of reusing the treated domestic wastewater for
agricultural purposes as an adaptation measure to climate change. The area under
investigation is Tlemcen Town, an arid region located in North Western Algeria.
Climate studies have shown that climate change through the drought that has occurred
in the past decades has affected the whole of the country and more particularly the North
Western region. This has been characterized by a negative impact on available water
resources as well as on the agricultural productivity. In Algeria, agricultural irrigation
is the primary water-consuming sector followed by domestic and industrial sectors. It is
therefore imperative to rationalize the use of conventional water resources. The reuse of
treated wastewater represents the alternative for the preservation of the available water
resources and the promotion of the agricultural sector. The present study is intented to
calculate water quality index (WQI) of an urban wastwater treatment plan, in Ain El
Hout in Tlemcen town , in order to ascertain the quality of water used in agriculture, to
detect the major problems in WWTP, to analyze the water quality parameters in
discharged effluents and to assess the water quality indices for the effluents discharged
from WWTP. There are several ways to assess the quality of water as deemed fit for
irrigation. Water quality index, indicating the water quality in terms of index number,
offers a useful representation of overall quality of water use, as well as in pollution
abatement programmes and in water quality management. A number of parameters
affect the usability of water for a particular purpose. In this study the water quality index
will be electrical conductivity, total suspended solids, dissolved oxygen, biological
oxygen determined on the basis of various physic-chemical parameters likexiv
