Domestic Water Supply

To examine the virucidal effects of various materials used for tubing in domestic water supply systems, experiments have been carried out that examine the recovery percentages of five viruses allowed to flow through pipes made from “aged” samples of five plumbing materials. Most materials had only modest virucidal effect, but copper produced significant reductions in levels of all five viruses.

Domestic Water Supply

Water is essential for maintaining life, ensuring a safe and continuous supply of water, therefore, it should be given the priority for concerns. Developing countries often face a number of problems with domestic water supply systems such as treatment plants with old technologies, degraded equipment leading to inefficient treatment, and a network of degraded piping, which could cause re-pollution of treated water during transport. Pleiku city, which is located in the Central Highlands of Vietnam, has built two treatment plants and a network of water supply pipelines in the core area. An analysis of the current state of the water supply system including water supply, treatment plant and pipeline system helps identify existing problems in the system. Through mixed methods, hazards or hazardous events are identified as a basis for risk assessment by using semi – quantitative method to assess raw risk and residual risk for each hazard. Priority risks are identified to focus on proposing the possible solutions that will improve the performance and management of domestic water supply systems.

WATER VENDORS PARTICIPATION IN DOMESTIC WATER SUPPLY IN UNGUWA UKU, TARAUNI LOCAL GOVERNMENT, KANO STATE, NIGERIA

Domestic Water Supply

Water vending is seen as a signing of a failure in piped-borne water supply systems, it still plays significant role in providing water especially to urban dwellers in many parts of developing countries, Nigeria inclusive. Therefore, this study examined water vendors participation in domestic water supply in Unguwa Uku, Tarauni LGA Kano state. The data used in this research collected from both primary and secondary sources. The data collected was analyzed using descriptive statistics, where simple percentages and tables used. The data analysis revealed that 57.4% of the residents in the study area patronized the services of water vendors.     Patronage of vendor service dominated the frequency with 64.9% of respondent’s patronage of vended water. Seasonal variation in vended water supply patterns exist in the study area, with dry season account for the highest water demand and most supplies occurred during morning and evening hours. Based on the challenges bedevilled water-vending activities, the study recommends that vendors should be recognized as an integral part of the system as this may help in the design and implementation of more comprehensive policies that better serve poor end-users, by ensuring greater accessibility and affordability of water vendor’s service.

Demand for drinking domestic water is continuously increasing specially in urban centres which experience high demographic expansion. The decrease of water losses in water supply networks can help preserve such a rare resource. Low number of water meters and intermittent supply make it difficult to quantify the leaking volumes of water. This article presents an analysis of the consumption for drinking water based on an extrapolation from a sample of consumers on whom data are available. Comparison of the volumes of water produced allows a determination of the losses in the water supply system. This analysis is completed by measurements of night flows. The results obtained may be relied on for an evaluation of the needs for drinking water in the South of Algeria, and for future regional development. The study indicates a high rate of water losses in the distribution network, reaching about 40%, and over-consumption due to an insufficient number of water meters and discontinuous supply. It is recommended that water meters come into general use and defective parts of the network are rehabilitated. We will try then to make the necessary recommendations in order to better functioning of the water supply systems in Algeria.
