Water Sensitive Urban Design (WSUD) treatment devices are often used to restore natural drainage properties in developed catchments. WSUD can make positive contributions to the restoration of natural ecosystem processes, by supporting trees and habitats in urban areas without taking up limited urban space. This paper reports on the development and testing of a new WSUD device, the Wicking Tank....

Good quality water supplies and safe sanitation in urban areas are a big challenge for governments throughout the world. Providing adequate water quality is a basic requirement for our lives. The colony forming units of the bacterium Legionella pneumophila in potable water represent a big problem which cannot be overlooked for health protection reasons. We analysed several methods to program a ...

UNLABELLED Avian and possum fecal droppings may negatively impact roof-harvested rainwater (RHRW) water quality due to the presence of zoonotic pathogens. This study was aimed at evaluating the performance characteristics of a possum feces-associated (PSM) marker by screening 210 fecal and wastewater samples from possums (n = 20) and a range of nonpossum hosts (n = 190) in Southeast Queensland,...

a large settling tank. There are five such tanks. They are connected with one another and a constant level is maintained in all. The capacity of each tank is 1.2 million gallons; the total capacity being 6 million gallons. The daily draw is about 2 million gallons. Hence theoretically the water settles for about 3 days before entering the Paterson filters. The engineer in charge, however, state...

In a hydroelectric power plant or in a pumping station in order to avoid sudden large increase of pressure due to instantaneous valve closure sometimes a surge tank is installed. The height of surge tank is designed by the highest possible water level during the operation. The theoretical treatment of oscillation in a surge tank is difficult because of the non-linearity of friction term in the ...

1 Description of the Model This case study is related to our CAV paper [4]. We consider a model of a water level control system using wireless sensors. This model is an extension of the one described in [1]. Values submitted are thus subject to probabilistic delays, due to the unreliable transport medium. A sketch of the model is given in Figure 1. The water level y of a Figure 1: CTMDP of the ...

This study investigated a small subset of the two community water-disinfection systems--hypochlorinators and tablet feeders-in rural Honduras. Levels of residual chlorine were assessed at three locations within the distribution system: the tank, the proximal house, and the distal house. The levels of residual chlorine were compared with the standard guidelines set by the Pan American Health Org...
