Water distribution systems in hilly areas are always divided into several zones due to the undulating terrain. The present approach of dividing water distribution systems lacks an assessment index and is characterized by a low degree of automation. With the building of a mathematical model, this paper introduces two indicators – pressure limitation and pressure variation – to enable the automatic division of the water supply pipe network. It prioritizes economic index as the objective function in the evaluation of the division of water distribution systems in hilly areas, and then selects the optimal division scheme by generic algorithm in a large number of candidates. The SY terrain in YW City China is used for verification. Compared to traditional water supply partition methods, this procedure is easier to operate time-savingly by staff and is more automatic.
HydraProbe used to improve water supply forecast from 3 SNOTEL sites in Idaho over traditional antecedent conditions using the principle component forecast model
Much of the water in the Western United States used for irrigation, municipal supplies and hydro-electric production originates as winter snow pack at higher elevations. Since the early 1900s, the correlation between stream flow and the snow water equivalent (SWE) has been used to forecast the available water for beneficial uses and assess...
Introduction
Access to clean water is of paramount importance for ensuring necessary levels of sanitation and health. According to the World Health Organization over 844 million people lack even a basic drinking-water service, including 159 million people who are dependent on surface water.
Globally, at least 2 billion people use a drinking water source contaminated with feces.
Contaminated water can transmit diseases such diarrhea, cholera, dysentery, typhoid, and polio. By 2025, the WHO estimates half of the...
Increasingly, more hydro projects are being integrated into existing conduit and canal systems such as potable water supply systems, waste water treatment plants and even on irrigation canals. Ossberger Hydro has a lot of experience in these types of projects with many features that have been designed specifically to address the characteristics of such projects. Shown below is an example of a project in a water supply system at Marron Creek and an article that goes into detail.

The water supply of the city of Vienna stems from high-source water pipelines of the Lower Austrian-Styrian Alps. Here, snow depth measurements play a major role. In the following, we explain, why this is so relevant and how it is monitored…
The snow depth is not only important in ski resorts. Experts estimate that up to 50 percent of annual precipitation falls as snow in the Austrian Alps. Apart from individual mountain stations, many measuring devices are located in the valley floor and record precipitati...
The Primozone ozone solution was installed at the Åland Water WTP in June 2007 and has been working perfectly ever since then.
The plant supplies 475 m³/h of drinking water to the population of Mariehamn, which is the larger part of Åland’s 27.000 inhabitants, and which doubles during the summer season. Åland is an archipelago of 6.500 islands. The process disinfects the water and removes colour and taste from humus.
Primozone replaces three air-fed generators
The turnkey delivery...
