Water is delivered to different supply zones for 24, 48 or 60 h each week with drinking water losses of around 50 60%.
Because of different supply zones, the large time constants and the non-linear building dynamics with respect to the different seasons, a CFMPC concept is proposed.
The permitting procedure helps to safeguard subsurface drinking water supplies by assuring that disposal wells are drilled and completed in a manner so the fresh drinking water supply zones are isolated from communication with any brackish or salty water zones.
The attack rate was ≈18 times higher in this supply zone than the rate in the other supply zones combined (6 ).
The local water company provided details of the water sources, water supply zones, number of houses and residents served by each water source and water supply zone, and treatment of water to each zone.
However, drinking water is usually distributed in different supply zones, with the result that the exposure is not necessarily universal.
A total of 85 water samples were collected from 12 monitoring sites in four water supply zones for THM analysis.
Water supply zones, the time interval of observation, age, and gender were not independently associated with having a case (Table 3).
Under regulations in force at the time the THM samples were taken, water companies divided their water supply into water supply zones, each zone covering a population of < 50,000 people.
In the HWC water supply system, water is piped into reservoirs in six water supply zones and then distributed to homes located in nine water distribution zones that contain the sampling sites.
