Researches

Hargeisa Water Quality Control Laboratory has an unique division for the development of researches and studies related to water quality. Water quality refers to the chemical, physical, and biological characteristics of water. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. based on the standards of its usage.

Hargeisa Water Quality Control Conduct in the last year Two main researches related to the water Quality :

  1. Assessment of Water Quality and Safety of Commercial Sources Supplying Water to Hargeisa City Households;

    On September 14, 2020, the Hargeisa Water Agency (HWA) inaugurated the Agency’s Water Quality Control Laboratory (HWQCL) for the purpose of ensuring that the water supply for the citizens was clean, safe and fit for human consumption.  This is the first large-scale undertaking of the HWQCL and covers initial testing of 40 water sources from which drinking water is supplied to Hargeisa households. In addition to the 40 wells, the study also included testing of all bottled water commercialized in Hargeisa as well as a small sample of end-user household storage tanks. It’s the initial installment of an ongoing detailed analysis of water quality ––physical, chemical, and microbiological. Testing and analysis were conducted during December 2020 and April 2021 and the findings and final recommendations are based on the guidelines and standards established by the World Health Organization (WHO) for drinking water.

     

  2. Assessment of Quality, Chemical Composition and Microbiological Safety of Bottled Drinking    Water Consumed in Hargeisa:

    On August 2021 The Hargeisa Water Quality Control Laboratory, a unit of the Hargeisa Water Agency, pursuant to its responsibility for safety and quality inspection of drinking water consumed in Hargeisa, conducted an in-depth assessment of physiochemical properties and potential microbiological contamination of 8 popular brands of bottled purified water manufactured in Somaliland.   Samples from all 8 brands were uniformly examined in the same period for physical properties including pH, conductivity, Total Dissolved Solids (TDS), and Turbidity, and mineral content such as Calcium, Chloride, Sodium, Fluoride, Nitrate, Manganese, Sulphate, Potassium, Iron, Lead, Cadmium, and Total Hardness.  All samples were also tested for microbiological contamination.  The results obtained during this first testing exercise showed that, in general, all brands had physiochemical properties lower than the WHO guidelines for Maximum Allowable Concentration (MAC).
