Water supplies to households by the water utilities in Nigeria have traditionally been confined within what is known as domestic water needs. The quantity of water supplied has traditionally been tailored to cover basic needs such as drinking, cooking and personal sanitation needs etc. However this has not been a true reflection of the use of this limited amount of water supplied. A social survey was made of households and institutions in Owerri city,Imo State, Nigeria? where productive uses of water is already real, particularly in activities such as home gardening, horticulture and livestock rearing etc. Emerging research across the developing world shows that millions of low income households use their limited water supplies for activities such as productive uses as well as domestic needs. Such productive uses of water may not really thrive or even take off unless the required quantity of water is available. Such activities often generate numerous benefits to households involved. An understanding of how productive uses of water could successfully be mainstreamed into urban water systems in Nigeria was studied and the report presented.
This monograph attempts to critically scrutinise the source of the limitations of the current development strategies such as private public partnership that seems to fail to redress pre 1994 challenges such as persistent unequal access to basic services such as water, land ownership and forced labour of the indigenes to meet their livelihoods. It also review the impact of private public partnership strategy in redressing past injustices especially when it comes to the issues such as land redistribution,access to basic services and as well as the role played by stakeholders such as multinational companies in the communication sector, i.e. MTN, Vodacom and Cell C and their utilisation of scrap containers in provision of services and sustainable development to the marginalised communities in the slave camps that are also known as townships, such as Bhambayi informal settlement.
The book examines study water quality and to the suitability for its use for irrigation purposes, also its effects on physical and chemical soil properties . there Parameters used for irrigation water quality assessment such as EC, pH, TH , SAR , Adj SAR, SSP, RSC , Mg ratio and Cl , also some heavy metals B , Cu, Mn, Fe ,Pb, Zn ,Cd , Co and Cr . There were notable effects for irrigation water on some physical soil properties such as soil texture , bulk density and saturated water content and some soil chemical properties such as pH, EC, soluble ions and exchangeable cations.
Access to potable water still remain an illusion to over one billion people which is manifested in high incidence of water and sanitation related diseases such as guinea worm. With the launch of the Guinea Worm Eradication Programme in 1989, interventions such as the provision of potable water and treatment of unwholesome water before use were pursued. Albeit these interventions, the worm is still prevalent in the Savelugu-Nantong District of Northern Ghana. This work investigated why in spite of the huge investment in water and sanitation facilities, as well as education campaigns, the disease is still persistent. The incidence of guinea worm over space does not relate with the distribution of water facilities; it is more preponderant in the south- eastern corridor and in the major communities where there is potable water. This book examines the relationship between water supply and guinea worm infestations and will be useful for water and sanitation sector stakeholders and practitioners such as staff of District Assemblies, Water and Sanitation Teams, District Health Directorate and the Guinea Worm Eradication Programme.
Working principle: the liquid level switch is composed of magnetic reed switch and float magnetic reed switch encapsulated within the guide bar when float move up and down with the measured liquid level its internal magnets attract magnetic reed switch contact action so as to detect the liquid level position as a liquid level control and instructions. Scope of application: household appliances (such as: pure water machine water machine drinking machine humidifier dehumidifier electric water heater air conditioning equipment household water direct drinking system etc.) industrial equipment (such as: empty hydraulic press air cooler drainage device lubricating oil system) gardening equipment medical equipment beauty salon equipment aquatic farming and industrial water purification sewage treatment system automatic door control system etc.

Most countries having dry and semi dry climate face distilled water shortage. By the same token, desalination of sea water quickly changed into a big source of desalinated water in many areas around the world. Desalination process is a process for purifying sea water for drinking consumption. Desalination process leads to refining salty water and removing salt and minerals from the water. The present study is an attempt to conduct a thermodynamic analysis of MED desalination distillation and its current types (including parallel feed water, forward feed water, backward feed water) to evaluate the effect of some input parameters such as motive steam temperature, concentration, and input water temperature on the efficiency of some output parameters on a desalination system such as GOR, heat loss through waste water, specific heat, and the amount of produced distilled water have been evaluated.
As a city located in delta area, the dense water network is the most important identity for Huzhou City. Now, the urban expansion and densification have completely changed the relationship between water and urban space. Admittedly, the new urbanization will improve the living condition of the local residents and stimulate the regional economy. However, if it's carried out according to the current plan, this goal is achieved with a sacrifice of other important qualities such as water condition, flood storage capacity, local identity, traditional culture, etc.Currently, the government has made great efforts for dealing with the potential threats and carried out a series of projects, such as water defense projects, river cleaning projects. This project will mainly focus on the new urban area, to see how to develop a sustainable living typology by re-achieving the good relationship between water and city.
