Definitions term definition & explanation blackwater flushing water from toilets brownwater faeces with flushing water but without mixing with urine Indices IX City Area (CA) represents the whole urban water system or one absolute independent water system in urban area, which is going to be the final IUWS. construction cost index (CCI) 1 a business cycle indicator showing the evolution of costs incurred by the contractor to carry out the construction process Conveying system water transport media including water transmission, distribution, sewer, storm drain, and their ancillary works desired water water has the quality satisfying the requirements of end uses. direct non-potable reuse pipe-to-pipe to reuse the reclaimed water for non-drinking purpose. If it is possible to be contacted by human beings, it must be hygienic safe. dual water system consists of dual separate mains (pipelines from separate sources) and designed to concurrently provide two separate water supplies to the consumer. One main conveys drinking (potable) water, the other conveys appropriately treated non-drinking water (WSA 2002). end-user’s water usage profile (EUWUP) each type of water end-user has specified and standardised information of water usage including water demand with required water qualities and used water amounts from different streams. greywater the used water coming from household activities other than toilets indirect potable reuse producer price index (PPI) 2 after being buffered in nature for certain period, the reclaimed water is used as raw water supply. a family of indexes that measures the average change over time in the selling prices received by domestic producers of goods and services raw water directly coming from the nature, such as surface water, groundwater and rainwater roof-water rainfall that is gathered from roofs of buildings sewage used to substitute for wastewater in the context source separated collection system (SSCS) the different used water streams from domestic activities are collected separately, whereby greywater and blackwater (or brown water + urine) are formed. reclaimed water treated wastewater that meets certain water standards or satisfy the quality requirements of water end-users 1 http://europa.eu.int/estatref/info/sdds/en/ebt/ebt_cons_pri_sm.htm (Statistical Office of the European Communities) 2 http://www.bls.gov/ppi/ppifaq.htm#1 (U.S. Department of Labor)
X New Conception and Decision Support Model for IUWS term definition & explanation Urban District (UD) the city area is divided into certain small sections, whereby each section has its independent water entity that is defined as Urban District. used water corresponding to the conventional term “wastewater”, involving different types of urban sewage water end use the final water use, or the place that water leaves the distribution system, e.g. toilet flushing, laboratory water end-user grouped water consumer, e.g. university, hospital water entity of GROUP type water entity of ZONE type water infrastructure system (WIS) holds the grouped water end-users that form the functional units of cities. It includes WUU and WUC. is planned and designed in the holistic perspective based on the area. It includes CA and UD. including all kinds of urban infrastructure for water intake, water treatment and water conveying water subsystem in conception of the IUWS, several subsystems are built up, i.e. water usage, water sources, desired water system, used water system, and rainwater system, which are finally constructed together as one IUWS. water usage contains the water information of water end-users, including water demands associated with required water qualities, and used water amounts with their water qualities. water usage scenario Water Utilisation Unit (WUU) Water Utilisation Cell (WUC) water end-user can have different water usages profiles, which results in different kinds of water usage, and they are named as the water usage scenarios. in general, it is the certain functional unit in cities and consequently, its water system can be managed and coordinated within one entity. It has the same structure as WUU but on a small scale that mostly focuses on the single big buildings or mono water end-users.
