Current World Health Organization and Centers for Disease Control and Prevention guidance for the disposal of liquid waste from patients undergoing treatment for Ebola virus disease at hospitals in the U.S. is to manage patient excreta as ordinary wastewater without pretreatment. The potential for Ebolavirus transmission via liquid waste discharged into the wastewater environment is currently...

In order to achieve ecological wastewater treatment, a “closed-loop treatment system” is recommended. Many present day systems are a “disposal-based linear system”. The traditional linear treatment systems must be transformed into the cyclical treatment to promote the conservation of water and nutrient resources. Using organic waste nutrient cycles, from “point-of-generation” to “point-of-produ...

In developing countries urban wastewater management often fails to cope with increasing wastewater generation. Financial, technical and institutional limitations force authorities to discharge substantial amounts of untreated or partially treated wastewater into surface waters. Consequently, uncontrolled use of polluted water is increasingly common in the downstream peri-urban areas. Although w...

Commercial and centralized oilfield wastewater disposal facilities (COWDFs) are used in the Western United States for the disposal of formation water produced from oil and natural gas wells. In Colorado, New Mexico, Utah, and Wyoming, COWDFs use large evaporation ponds to dispose of the wastewater. Birds are attracted to these large evaporation ponds which, if not managed properly, can cause wi...

s and Reports 253 thorities are now appropriately being given the responsibility to manage, operate, and maintain sewerage systems. The Trinidad and Tobago Water and Sewerage Authority, perhaps the most advanced in the Eastern Caribbean, has a well-structured and staffed wastewater section with the authority and expertise to pursue the country’s plans for extending sewerage systems in the dense...

abstract population increase, limitation of water resources, and increasing volume of municipal wastewater, has caused the necessity of wastewater reuse. application of wastewater on soils seems to be the most economical method of its disposal and by percolating wastewater through the soil, its chemical quality is improved. for this purpose, a greenhouse experiment was carried out with polyethy...

This section describes existing public services and utilities, presents analysis of potential impacts resulting from Regional Plan Update alternatives, and identifies any mitigation measures for those impacts determined to be significant. In particular, it addresses impacts on water supply, wastewater treatment and disposal, electricity, natural gas, solid waste, schools, fire protection, and l...
