IP codes IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures ...
The Convention on the Protection and Use of Transboundary Watercourses and International Lakes, also known as the Water Convention, is an international environmental agreement and one of five UNECE's negotiated environmental treaties. The purpose of this convention is to improve national attempts and measures for protection and management of ...
An example of where backflow would harm the water supply is the use of well washing devices inside underground sewerage pumping stations. At times untreated sewerage may contain a variety of harmful gases that will effectively break down and deteriorate concrete wells, hence well washers are utilised to spray water and wash down contaminated ...
Source water protection—Taking action to minimize adverse impacts on source waters reduces the risk from pathogens and chemical pollutants in that water, and can also reduce the degree of treatment required. Robust water treatment—Having treatment trains with more than one step provides redundancy against treatment failure.
There are three key components to any Water Safety Plan (WSP): [4] a system assessment, which determines if the drinking water supply chain as a whole is capable of supplying water of sufficiently high a standard to meet regulatory targets; operational monitoring, in order to identify control measures in the drinking water system; and
Source water protection is a planning process conducted by local water utilities, as well as regional or national government agencies, to protect drinking water sources from overuse and contamination. The process includes identification of water sources, assessment of known and potential threats of contamination, notification of the public, and ...
Beginning in the 20th century, designers of industrial and municipal sewage pollution controls typically utilized engineered systems (e.g. filters, clarifiers, biological reactors) to provide the central components of pollution control systems, and used the term "BMPs" to describe the supporting functions for these systems, such as operator training and equipment maintenance.
For example, homes can be put on stilts, [25] electrical and HVAC equipment can be put on the roof instead of in the basement, and subway entrances and tunnels can have built-in movable water barriers. [26] New York City began a substantial effort to plan and build for flood resilience after Hurricane Sandy. [27]
