The Importance of Dewatering
With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game. Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control groundwater on a ...

3 reasons why dewatering is important for your construction project
If you are an experienced construction company, then you likely understand how important dewatering is for any construction project where water is a problem. You could be building or repairing a bridge or a rampway. No matter what you are doing, the presence of water is a problem. If perhaps you are new to working with water, here are three reasons why dewatering is important for your ...

Water supply structures of the Ottoman period in Istanbul (Asian side)
The city of Istanbul has land on both the Asian and European continents. On the European side, many waterways (culverts) were constructed to supply water to the old city; however, on the Asian (Anatolian) side, such water supply structures were limited in number and capacity. Therefore in order to meet the water demand of this side of the city, foundation waterways were built. This study ...

An agenda for deliberative water governance arenas in the Mekong
Closely related to justice, this article explores how water governance can be fairer and more effective in the Mekong Region where choices are being made about using and sharing waters that might produce more energy; increase or decrease food production; sustain or threaten livelihoods; and maintain or degrade vital ecosystems and their services, upon which societies depend. Debate and ...

Heat transfer enhancement of falling film evaporation on a horizontal tube bundle
The enhancement of the evaporation heat transfer coefficient is important for the design and operation of horizontal tube spray film evaporators. The water spray on a horizontal tube bundle is numerically studied in steady state conditions. The objective of the present work is to numerically study the effect of the tube configuration and the operating conditions on the evaporation heat transfer ...

Multi–physical field information comprehensive analysis and application of tunnel water–bearing structure
Water inrush and burst mud cause great hidden danger and economic loss, so it gradually became an important technical problem for tunnel construction. The prediction principle of seismic wave method, electromagnetic wave method, and electrical method were analysed. The merits and demerits of the three methods in the prediction of tunnel water–bearing structure were compared. The superiority of ...

The Infrastructure Build-Neglect-Rebuild Cycle
With financing structures like BOO and BOOT, a private company takes over operations of public infrastructure, including maintenance Construction of new water infrastructure is often the first solution considered to address water challenges, but decision-makers frequently underestimate the costs of long-term operations and maintenance (O&M). After spending large amounts of capital, ...

Integrated Constructed Wetlands: concept, design, site evaluation and performance
'Integrated Constructed Wetlands' (ICW) are a joined-up approach to land and water management. Significant synergies were achieved by explicitly combining environmental, ecological and aesthetic objectives. Intercepted precipitation was found to be the main factor determining treatment efficacy. Soil infiltration and evapo-transpiration combined to enhance hydraulic residence time. A wetland area ...

A contingent valuation study of Winnipeg municipal water using bounded rationality
Contingent valuation (CV) is a survey technique used to value environmental goods not traded in markets, such as improvements to air or water quality. Despite its popularity, widespread acceptance of this methodology has been hampered by controversies stemming from numerous behavioural anomalies such as preference reversals, embedding and starting point bias. This study argues that these ...

How Can Decentralized Water Systems Save Money for Governments and Communities?
The construction of water treatment facilities has traditionally been directed by the community’s need for reliable and dependable water quality. However, particularly in recent years when budgets have not grown to meet the expanding population, the need to lower the costs of delivery and production of drinkable water has become a factor in this equation. In the past, many countries have ...

Experimental study of falling film evaporation on horizontal tube bundle for a desalination unit
The objective of the present research is to experimentally study the effect of the tube configuration and also the effect of the operating conditions on the evaporation rate of the horizontal tube bundle. An experimental test loop was installed and the water spray on a horizontal tube bundle with three nozzles of fan-jet flat nozzle type. The results show that evaporation rate and Nusselt number ...

Case Study - Groundwater Discharge Permit - Plymouth, Massachusetts
The process of obtaining a groundwater discharge permit for a subdivision scale septic absorption system was faciliated by using the advanced GIS features within EnviroInsite. Geologic features were downloaded and presented at the site scale along with the subdivision boundary and potential downgradient receptors. A cross-section was created showing the detailed soil descriptions, water levels ...

Historical development of rainwater harvesting and use in Hellas: a preliminary review
The uneven temporal and partial distribution of water resources in Hellas, and especially southeastern regions, has resulted in the construction of various water systems for collection and storage of rainwater, since their very early habitation. Ever since, technologies for the construction and use of several types of cisterns and other relevant hydraulic strictures have been developed. The ...

Privatization of Water-Resource Development
This paper analyzes the inefficiencies from market power and return-flow externalities in private construction of a water project. The model pays special attention to increasing groundwater pumping costs, project set-up costs, limited project capacity, and return flow to the aquifer. For a given capacity, the return-flow externality causes project owners to construct the project too late when the ...
