Book Description
Written for water and wastewater utility personnel, the collection of 30 articles provides a basic template of how DB projects can be planned, procured, and executed. Discussions include how the processes and procedures of design-build differ from those of design-bid-build, their impact on preliminary design and planning, procurement, and project execution.

Book Description
Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

Book Description
In the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.

NOTE TO THE READER: All forms and material that were previously on a CD-ROM that accompanied this book have been moved to the following web site: http://booksupport.wiley.com Tested-and-proven techniques for quick, accurate estimates Here is the first manual that guides engineers, planners, and contractors through the process of estimating the cost of building water treatment facilities. Based on more than eighty years of the two authors' collective experience, the Cost Estimating Manual for Water Treatment Facilities not only enables you to arrive at a dependable estimate, it shows you how to do it quickly with a minimum of information and supporting data. In order to ensure reliability, the authors have compiled and analyzed the results from their own construction cost estimates for more than 500 projects as well as the results from many other engineers and contractors. The manual identifies forty-three treatment processes, nine types of water treatment plants, plus five additional types of advanced water treatment plants. The authors then demonstrate how to calculate costs for each element, accounting for needed mark-ups and allowances in order to arrive at the total plant construction cost. To help you make your own estimates, the manual provides: Examples of cost estimates for different water treatment processes Historical data from several public agencies Sample tables for 10 mgd and 100 mgd product water flow rates for each type of treatment plant Website access with Excel spreadsheets that enable you to perform estimates using your own data Now that the Cost Estimating Manual for Water Treatment Facilities is available, you no longer have to rely on hunches and anecdotal information; you have a proven, scientific method that leads to reliable estimates.

Book Description
FROM THE PREFACE Since Federal funding is scarce for massive upgrades, and/or complete new Wastewater Treatment Plants (WWTP) construction, treatment plant operators, superintendents, managers, city councils, boards, etc. must get more creative on funding and coordinating process equipment replacements. Contained herein you will find hints, tactics and procedures aimed at getting the "biggest bang for your public buck." During the 1970s and 1980s, through grants, the Federal Government paid 80% of costs to build new or expanded wastewater treatment plants, pumping stations and collection system renovations. The majority of the grants were to upgrade primary treatment facilities to secondary, and secondary to tertiary treatment status based on Clean Water Act regulations. If your facility was fortunate enough to receive grants, you were in good shape for approximately 20 to 30 years (depending on community growth rates). Since most wastewater treatment facilities are designed to last 20 years, many of the new or expanded facilities in the 70's and 80's are reaching the end of their service life. Some may have reached it sooner due to growth beyond the expected rate, inadequate preventive maintenance, or design inadequacies when built. Now you have identified problems with insufficient aeration capacity, equipment mechanical failure, insufficient pump station capacity, infrastructure deterioration, etc. and need to do something about it before you violate your NPDES permit (if you have not already). This equipment seems very costly to replace because you now must pay 100% opposed to 20% with the grants. Many WWTP are in need of replacement and/or upgraded equipment. The equipment itself is typically about 25% to 50% of the total project cost. This cannot be changed much. However, the remaining 50% to 75% (engineering, installation labor costs and project management) may be whittled down dependent on how active and creative the project coordinator (yourself) wants to be in the process. When EPA funded 80% of project costs in prior years, it was no big deal to have an "open pocketbook" attitude. Those days have changed forever and so have procurement procedures for projects. A Management Guide to Retrofitting Wastewater Treatment Plants is geared towards the managerial and administrative scope of a Lead Operator, Superintendent, Facility Manager type of Wastewater individual. All the junior college courses available, practical operator experience, and certification status will still not offer the opportunity to learn administrative and cost savings techniques (similar to operating a business). But soon, your job may demand these skills. This book is a handy reference for making the task of upgrading/retrofitting wastewater process equipment easier and less costly. It includes ideas for selling upgrade ideas to superiors, pre- and post-project activities, and certain management techniques useful for successful retrofitting or upgrading in past projects. This book should prove helpful to those who find themselves involved in retrofitting their facility, and need assistance on resolving facility problems, including treatment plant operators, superintendents, managers, city council members, and boards. It is also a valuable reference guide for municipal operations individuals who want to retain control of their facilities, but don't quite know how. It was written with the front line operator, superintendent, and manager in mind, in common operator language in order to allow easier understanding. It contains many tips and techniques which operators can implement immediately.
