Water rate to manage residential water demand with seasonality: peak-load pricing and increasing block rates approach
A strong seasonal demand for water occurs in many tourist areas, which might exacerbate the water shortage problems. Water pricing is a key instrument for water use management; therefore, the objective of this work was to design a variable water rate to examine the seasonal water demand in water-scarce regions. The proposed water rate combines the peak-load pricing (PLP) and increasing block ...
