摘要:

After the Colorado Water Quality Control Commission levied a fine for discharge permit violations to the operators of a sand and gravel mine, a trial court upheld the commission's decision. An appeal, claiming that due process was denied because of use of evidence regarding inspections, was not upheld by the court. The court said that “Due process does not require that notice of inspections be provided after observations made by a private individual.”

摘要:

The array of available computers and related hardware can be overwhelming—even to individuals who are computer literate. Those who are marginally familiar with or have neither the time nor the desire to keep abreast of rapidly changing hardware technology must rely on outside advice in choosing the right system for their needs. The advice can be taken on blind faith or can be evaluated based on a basic understanding of the characteristics and applications of available computer hardware.

摘要:

Computer control of the Hardhof groundwater plant is necessary to adhere to operational criteria stipulated by the canton of Zurich. Drawdown cannot exceed the licensed levels of the wells, and to maintain water quality, recharge of the wells from the Limmat River must be balanced against streamflow and the direction of runoff within the wellhead protection zones. The computer installation at Hardhof also assists with managing energy costs for the city's water supply and security systems for the physical plants.

摘要:

A new computer‐based supervisory control and data acquisition (SCADA) system controls and monitors the Honolulu Board of Water Supply's pumping, storage, and distribution operations. Two operator consoles with color CRTs display water system data in symbol form and in trend format and also control pumps and valves at remote stations. In addition, the system automatically generates reports from the data it collects. Software is currently being developed that will reduce electrical power costs by time‐controlling pumps to take advantage of off‐peak rate schedules.

摘要:

Water consumption data is the most variable and uncertain parameter in water distribution system analyses. Establishing a reasonable distribution of consumption within a water system model is a tedious and time‐consuming task that is essential for the success of any analysis or modeling effort. At the Washington Suburban Sanitary Commission in Hyattsville, Md., the process of water consumption data manipulation was automated by a series of computer programs and data sets referred to as the water demand software.

摘要:

A multiobjective optimization model that describes the water supply system of the Indianapolis (Ind.) Water Company has been formulated and tested. This linear program is proposed as a tool for studying the operation of the system during periods of drought. Four conflicting objectives, eight supply sources, three reservoirs, and twelve pressure districts are included in the model, which was used to study both long‐term and real‐time operations.
