How to Build a Water Demand Model for Libya?

Published on by in Academic

I am working on estimations of the demand for water in Libya.

I am looking for forecast of the demand for water and have this data - income population, temperature, quantities of the water consumption, for agriculture and industry.

My question is, how can I build a model?

  1. First you need to be clear what you mean by demand. If this is the distribution input needed to maintain supplies to all connections from the water distribution system, and at the same time keep the system adequately pressurised, then in addition to the actual consumption by users drawing water from the connections you will need to consider losses from the network. These physical losses can be large, especially if there has been a lack of active leakage control in the past. Nowadays we talk about NRW (Non-Revenue Water), which includes not only the physical losses but also commercial losses (e.g. water theft and unbilled consumption due to poor connection and metering records). I would not be surprised if NRW in Libya was 50% or more of distribution input, but it can be difficult to estimate.

  2. Hi Jamal, Don't you have precipitation data?!! Evaporation might be estimated via tempretature data, but you can not develop a model without knowing about the input which is the precipitation data.

    1. hi jamal, You must carry out an inventory of groundwater wells drilling wells and sources in various agricultural industry etc is necessary for the model

    2.  i am looking for forecasting of  demand of the water in Libya you can say relationship between population   i thank we have tree types of  the water (  agriculture  domestic  and the last one industry )
