Abstract:

Self supply systems are privately owned household water sources. The systems are generally perceived as playing a role in water service delivery to the rural poor. The systems' yielding safe drinking-water also receives little attention in literature and policy, relative to public and communal sources. This paper assessed urban self supply wells and argues that self supply is a coping water supply strategy of not only the rural poor, but also of the unserved in the cities. The assessment included inventory and classification of sources, forms of access to sources, types and number of users in

Abstract:

In the Republic of Korea, multi-regional water supply pipelines were intensively laid during the rapid economic growth period; however, these pipelines are now aging. The cost of renewal of the aged pipelines would be enormous. Therefore, limited resources need to be distributed effectively in accordance with the priority of renewal. In this study, the risks involved in the multi-regional water supply pipeline of region K were calculated and assessed for setting the priority of renewal. The probability of failure of the pipeline was calculated through a quantification theory, and the effects o

Abstract:

The population in urban areas is growing rapidly; from 30% in 1950 to about 50% at the turn of the century. In 35 years time, the number of large cities (greater than one million) will double and the population living in them will triple. Most large cities are already facing water supply problems and these will increase in the future. Water reclamation for nonpotable reuse for urban irrigation, industry, toilet-flushing, cooling, construction etc. can reduce the demand on limited fresh water resources. Many urban areas around the world have already used this approach to meeting problems of inc

Water quality and supply are central to the socio-economic development of any nation. Scarcity of potable water results in the construction of dams and water treatment plants. Unfortunately, provision of potable water through improvement and treatment may prove to be difficult because of the socio-economic activities around a dam. This study is aimed at assessing the socio-economic activities around the Alau Dam Maiduguri, and how they affect the quality of raw water supply to Maiduguri Water Treatment Plant.

The universalization of drinking water in rural communities poses a great challenge to developing countries, where rural areas often receive poor water service coverage and limited attention from authorities.

However, its sustainability depends on several aspects. The authors of the current paper performed a thorough review of relevant publications in the rural san

Abstract:

Land problems in urban areas are very complex land issues, high rates of population growth, accompanied by the construction of residential areas, industrial estates and shopping areas which have led to increasing demands for land supply. In line with land use and urban land development, it causes frequent conflicts or land problems. The Nontrol Village of East Sentani District is one of the villages that has a Sago Forest Land which is protected by the Sago Forest Protection Act, and due to water infiltration, the community around the project area is very disturbed by the existence of the proj

The paper examines the emerging pattern of governance in metropolitan Lagos and its neighboring settlements taking cognizance of environmental sustainability in the 21st Century with its attendant challenges. The work specifically highlights the metropolitan status of Lagos as a megacity and the issue of having to cope with its incessant population growth vis-à-vis the paucity of basic amenities needed to shove off such a highly vulnerable and competitive milieu.The work employs secondary data to elicit necessary information for its analysis and findings. Such data includes (but not limited to

Abstract:

Anything in the environment which can be used is called a ‘natural resource’. Protecting the environment from destruction is called conservation of environment. Some of our important natural resources are forest, wildlife, water, coal & petroleum. The resources of the earth are limited because of the rapid increase in population. The demand for resources is increasing day by day. The proper management can ensure that the natural resources are used judiciously so that they fulfill the needs of present generation and also last for the generations to come. Water is the basic

Abstract:

This study investigates the different stakeholder based discourses and challenges around the Franconian Lake District (FLD), a recently constructed large reservoir system in Germany. The construction and operation of reservoirs represent a massive alteration of their natural and social environments leading to discourses and potential conflicts between a wide scope of heterogeneous interest patterns. Studies have shown that large reservoirs can be an important contributor to water supply, irrigation, energy storage and therefore climate change mitigation on a global scale, which brings these co

Abstract:

The growing deterioration and unsatisfactory technical condition of the pipes of water supply and wastewater disposal networks in Russian cities and other inhabited localities, as well as limited (under the conditions of Russian housing and utilities sector reforming) funding of pipeline renovation and rehabilitation have considerably aggravated the problem of pipe reliability provision. These factors make pipe renovation and rehabilitation quite a topical issue. A very promising trend in the field of pipeline construction and renovation named “trenchless technologies” has been commonly used i

Abstract:

Challenges of energy security, low carbon transitions, and electricity network constraints have led to a shift to new, efficient technologies for household energy services. Studies of such technological innovations usually focus on consumer information and changes in behaviour to realise their full potential. We suggest that regarding such technologies in existing energy provision systems opens up questions concerning how and why such interventions are delivered. We argue that we must understand the ways by which energy systems are co-constituted through the habits and expectations of househol

Abstract:

Excessive use of potable water in irrigation can be reduced considerably through treated wastewater reuse specially when fresh water resources in Qatar are scarce and the water supply depends on the limited groundwater and costly desalinated water. In view of the use of treated effluent in irrigation, the infiltration of brackish groundwater into the sewerage system should be eliminated and stringent standards to control leakages should be laid for new construction. The wastewater treatment methods and the effluent quality in general meet the criteria and standards governing the use of effluen

Abstract:

The current practice of hydraulic engineering construction applies four methods for damping extra energy of excess water discharge: throwing out the stream into the tailwater; using twisting of the stream in the water passageway, in a water-well, and on a multistage drop; and energy damping in a vertical shaft. The cheapest method is energy damping by throwing the jet into the downstream reservoir. The main disadvantages limiting the use of this method include the need for appropriate topographic conditions in the tailrace basin, strong rocks in the river channel, and the possibility of water

This paper presents one of the first detailed studies of mangrove forest history. Historical changes in mangroves and their use were examined in Bais Bay and Banacon Island, Philippines. Cutting to make space for fish ponds and residential settlement has dramatically reduced the distribution of mangroves in Bais, although forest has expanded rapidly near the mouth of the largest river where soils from nearby deforested hillsides have been depos

Abstract The hydraulic implications of stomatal positioning across leaf surfaces and the impact on internal water flow through amphistomatic leaves are not currently well understood. Amphistomaty potentially provides hydraulic efficiencies if the majority of hydraulic resistance in the leaf exists outside the xylem in the mesophyll. Such a scenario would mean that the same xylem network could equally supply a hypostomatic or amphistomatic leaf. Here we examine leaves of Helianthus annuus to determine whether amphistomaty in this species is associated with higher hydraulic efficiency compared w

In the construction field, EFBP fibers can contribute as a mixture of substances for cement tile products. The purpose of adding fiber is to distribute the stress on fibrous cement roof tiles. With evenly distributed stress, the strength of the tile will be higher. The production process of EFBP fibrous ceme
