Conjunctive Water Management

The drinking water supply to Vila Pouca de Aguiar municipality in North Portugal is based on high quality groundwater, namely on nearly one hundred artesian springs and fifty boreholes. The groundwater resources are plentiful on a municipal level, but evidence some deficits at the sub-municipal (village) level, especially during the dry period (July- August) that coincides with the return of many emigrants for holiday time. The deficits affect mostly the municipal capital (Vila Pouca de Aguiar) and a neighboring village (Pedras Salgadas), which populations nearly double or even triple during that period. The estimated annual deficits approach 55,000 m3/yr in those villages. If the anticipated increase in consumption/habitant and decrease in annual rainfall become reality in the next two decades, then the deficits may raise to approximately 90,000 m3/yr. To balance the water supply system, this study proposes its transition towards a conjunctive water management based on surface water stored in small dams and groundwater. A hydrologic modeling involving small forested catchments (< 15 km2) elected the Cabouço watershed as most suited basin to store stream water, because surface water availability is large (2.4 Mm3/yr) and forest cover is dominant (84.8%). Estimated nutrient loads are also compatible with drinking water supply.

Taourit-Oujda corridor (T.O.C.) is a geological entity of north-eastern Morocco with a total area of 4000 Km2. The drinking water supply in this arid region still faces challenges that meet a growing demand for a shortage of fresh water. This shortage is mainly due to the scarcity and irregularity of the precipitations, the overexploitation of the water resources, and the decrease of the capacity of storage dams that are the main source of drinking water supply in this area. This work aims at estimating deficit (to 2040) for drinking water provided by Machraa Hammadi dam and proposing favourable drilling sites to strengthen drinking water supply through the identification of groundwater resources that can be used in quantity and quality. To do this, a multi-criteria analysis (MCA) covering geological, hydrogeological and hydro-chemical aspects using the Geographical Information System (GIS) was carried out. This study shows that T.O.C. aquifer is more productive in the south-west of it, in the centre near the El Aioun municipality and in the north-east at the town of Sidi Bouhouria. According to Moroccan standards, defining the quality norms of surface waters, waters destined for irrigation, and of surface waters used for the production of drinking water, the groundwater in the center and north-east areas is also with good to medium overall quality groundwater.

Availability of safe drinking water is considered a key challenge in the coastal region of Bangladesh. High concentrations of salinity, iron and arsenic, and the unavailability of suitable aquifers, have deterred the exploitation of groundwater resources. In addition the cyclonic storm surge is a major threat to this system. Cyclones accompanied by storm surges in the coastal area cause significant deterioration of drinking water supply and sanitation. Water professionals have launched some initiatives to promote small-scale, alternative safe water sources (e.g. rainwater harvesting, pond sand filters and piped water techniques) to provide sustainable solutions to the problem. However, a systematic evaluation of the alternatives that considers social, technical and economic criteria has not been carried out so far. The present study is an attempt to evaluate the alternative options for drinking water supply in a cyclone-prone area. The authors conducted a multi-criteria analysis and reached the conclusion that rainwater harvesting is the most suitable option for the area. Moreover, the final result was shared with the users to obtain their feedback to ensure sustainability of the water source.

Analysis and characteristics of groundwater resources of the region particular territories have been presented in the work, and assessment of their qualitative structure has been given. It has been shown that the use of groundwater for the purposes of public drinking water supply demands obligatory correspondence of its quality to the drinking standard.
