This design aims to contrive a plumbing system X Apartment, Jakarta with a separate clean water and drinking water system. Water supply system that applied to this apartment is roof tank system. Fluctuations in the use of clean water are used to determine the capacity of reservoirs and pumps using the equivalent apartments such as The Bellagio Residence Apartment, Four Winds Apartment, Tamansari Sudirman Apartment, and Setiabudi Residence Apartment. Total demand for clean water for the 1st and 2nd tower is 315.8 m3/day and 39 m3/day for drinking water with 216 m3 of ground water tank capacity. Transfer pumps work for 12 hour/day and the capacity of clean water roof tank for the 1st and 2nd tower are 67.5 m3 while for drinking water roof tank are 7.2 m3. System that has been chosen used 2 stand pipes for both clean water, drinking water, and booster pumps in each tower. This design concluded that The investment cost of clean water and drinking water system and also the construction of X Apartment reservoirs is Rp. 2.393.889.860 and the cost of drinking water that can be saved by residents when using drinkable tap water system is Rp. 874.656 per m3.

This concept paper discusses the potential impact of chlorinated public drinking water on the assembly of the intestinal microbiome in infancy. The addition of chlorine or hypochlorite to metropolitan drinking water is routinely used worldwide as a sanitizer because of its potent anti-microbial properties. It is one of the most effective means of delivering safe drinkable water because it produces a residual disinfectant that persists within the distribution system. Levels of chlorine used to treat metropolitan water are considered safe for the individual, based on toxicity studies. However, to our knowledge there have been no studies examining whether levels of persistent chlorine exposure from tap water are also safe for the ecosystem of microorganisms that colonize the gastrointestinal tract. Given the importance of the microbiome in health, persistent exposure to low levels of chlorine may be a hitherto unrecognized risk factor for gut dysbiosis, which has now been linked to virtually every chronic non-communicable disease of the modern era. Although effects may be subtle, young children and infants are more susceptible to ecological disturbance, given that the microbiome is highly influenced by environmental factors during this period. Here I outline considerations for the safety of water disinfectants not just in terms of toxicity to the host, but also for the ecosystem of microorganisms that inhabit us. Research in this is likely to bear fruitful information that could either bring attention to this issue, potentially driving new innovations in public water management; or could help confirm the safety profile of chlorine levels in public drinking water.

How individuals perceive the safety of their public drinking water influences whether they reach for the tap to quench their thirst, or an alternative such as bottled water or a sugary drink. In turn, mistrust of drinking water quality and subsequent reliance on alternative beverage sources can adversely impact health, welfare and the environment. Using data from the 2013 American Housing Survey, we provide the first national, rigorous assessment of individuals’ perception of their public drinking water supply. We found strong evidence that perception of water quality is most influenced by individual and household indicators of socioeconomic status – education level, household income, racial or ethnic minority status, and most importantly foreign-born nativity, especially from Latin America. By contrast, our findings provide little indication that perception is tied to known built environment or neighborhood risk factors affecting water safety and quality. We outline the implications of our findings for proponents of enhanced tap water consumption, including public drinking water systems, county public health agencies, and particularly for environmental justice non-profits.

In this research, methodology was developed to identify locations vulnerable to taste and odour problems in a distribution system. The methodology was based on a multicriteria procedure combining spatial information on consumer complaints and popular perception of tap water. The first step in the described methodology consisted of mapping complaints regarding tap water made by the population between 2002 and 2004 using a geographical information system (GIS). The second step consisted of analysing results of a questionnaire-based mail survey, also through GIS. The information generated using the above steps was integrated using a multicriteria and spatial approach allowing segregation of the distribution system into delineated zones, according to their vulnerability to occurrences of taste and odour problems. The identification of vulnerable sectors in a distribution system will help water managers to implement a better-targeted water quality monitoring programme – one that considers odours and tastes of drinking water – within the management process.

Abstract A full-scale reproduction of an aircraft drinking water system was conditioned using municipal tap water with a mixture of free chlorine and chloramines, and subsequently contaminated with coliforms. Disinfection was undertaken using chlorine dioxide, ozone and a mixed oxidant solution followed by flushing until no disinfectant residual remained. Results showed that coliforms were not persistent on the aircraft plumbing surfaces, and coliforms were not detected after disinfection and flushing with any disinfectant. The one exception was the aerator installed in the lavatory faucet, which was coliform positive after disinfection with ozone and mixed oxidants. These data suggest that the faucet aerators could be a source of coliform contamination that may result in coliform positive samples. Further experiments conducted on disinfection of aerators with glycolic acid and quaternary ammonia (both commonly used by the airlines) showed no detectable coliforms on coliform contaminated aerators after 30 minutes of soaking in the disinfectants.
