We discuss how Delft-FEWS is applied to incorporate real-time sensor data and dynamic modeling to allow Real Time Control (RTC) of three sewer systems in the area of the Hoeksche Waard, the Netherlands. The purpose of this project was to reduce sewerage spilling to the surface water by optimizing the available storage in the sewer systems. In this paper we will present how Delft-FEWS makes use ...

Nowadays, the increase of human population every year results in increasing of water usage and demand. Saen Saep canal is important canal in Bangkok. The main objective of this study is using Artificial Neural Network (ANN) model to estimate the Chemical Oxygen Demand (COD) on data from 11 sampling sites. The data is obtained from the Department of Drainage and Sewerage, Bangkok Metropolitan Ad...

Male-specific bacteriophage (MSB) densities were determined in animal and human fecal wastes to assess their potential impact on aquatic environments. Fecal samples (1,031) from cattle, chickens, dairy cows, dogs, ducks, geese, goats, hogs, horses, seagulls, sheep, and humans as well as 64 sewerage samples were examined for MSB. All animal species were found to harbor MSB, although the great ma...

A new problem in technology policy-a discipline hitherto largely concerned with the modern industrial sector-is posed by the need for technology suited to creating productive jobs and providing minimum public services at a cost and level of sophistication within the reach of poor people in developing countries. Careful consideration must be given to overall and sectoral development objectives, ...

Halifax is situated 44? 40' north latitude, and 63? 31' west longitude. It is built on a promontory and nearly surrounded by water, and lies on a slope opposite one of the noblest harbours in the world. Its position is admirably adapted for sanitary purposes. There is a well arranged system of sewerage; the houses are not overcrowded, and actual want is unknown amongst the population. The tempe...

Groundwater management by water service providers in Lusaka, Zambia, includes borehole siting, drilling and on-going monitoring. Semi-structured interviews were conducted with Lusaka Water and Sewerage Company (LWSC) and devolved Water Trust managers, in order to assess their needs and collect their suggestions to improve data management. The research found that both the Water Trusts and LWSC l...

Abstract This article offers a comparison of the detected defects in sewerage systems operated by water companies and self-operators, determines their quantity classifies them into individual categories. The determination number at self-operators is evaluated on basis performed camera inspections compared with data provided company.
