Pricing policies play an important role in water demand management and its optimal allocation. Determining proper water price leads to optimal allocation of water especially in agricultural consumptions. Applying new subsidy targeting law in Iran which insists on pricing water based on its supply cost, will effects considerably on water resource management in agriculture sector. So, in this stu...
Drinking water has received considerable attention recently. However, misuse and mismanagement have resulted in a rapid and widespread decline in source-water quality and supply. Water quality guidelines can be used to identify constituents of concern in water, to determine the levels to which the constituents of water must be treated for drinking purposes. Membrane technology for the water cyc...

background: reverse osmosis (ro) is an increasingly common method of desalination. a full scale water desalination system by membrane technology (ro) evaluated in a southern city (jask) in iran. methods: first, data collection on water supply and network were performed. analysis on most of the water quality parameters (turbidity, ph, ec, cl-, na+, alkalinity, ca, na, k, no3, no2, fe, mg, mn, nh...
A city consumes a large amount of water. Urban planning and development are becoming more compelling due to the fact of growing competition for water, which has lead to an increasing and conflicting demand. As such, investments in water supply, sanitation and water resources management is a strong potential for a solid return. A pilot project of greywater ecological treatment has been establish...

Rainwater harvesting (RWH) may be an effective alternative water supply solution in regions affected by water scarcity. It has recently become a particularly important option in arid and semi-arid areas (like Mediterranean basins), mostly because of its many benefits and affordable costs. This study provides an analysis of the reliability of using a rainwater harvesting system to supply water f...
Water supply is a core service on which civilised society depends. It involves considerable energy consumption and, as a result, CO2 emissions (in water treatment, pumping and monitoring) and economic costs. Treated water is most commonly supplied from a central storage reservoir by gravity throughout a catchment and this water must be supplied within satisfactory pressure bands. Where the pres...
