Potential health implications of water resources depletion and sewage discharges in the Republic of Macedonia
Potential health implications of deficient sanitation infrastructure and reduced surface water flows due to climate change are examined in the case study of the Republic of Macedonia. Changes in surface water flows and wastewater discharges over the period 1955–2013 were analyzed to assess potential future surface water contamination trends. Simple model predictions indicated a decline in ...

Source identification of fecal contamination in the canals in Bangkok using fecal sterol compounds
This study aims to apply fecal sterols as a chemical indicator to track feces contamination sources in the canals in Bangkok. The sewage and canal sediments were examined during the dry season. Fecal sterols in the canals were evaluated over a one-year period (2011–2012) for the selected sterol compounds. Several factors including season, canal water levels, rainfall data, and sewage were ...

Standardised survey method for identifying catchment risks to water quality
This paper describes the development and application of a systematic methodology to identify and quantify risks in drinking water and recreational catchments. The methodology assesses microbial and chemical contaminants from both diffuse and point sources within a catchment using Escherichia coli, protozoan pathogens and chemicals (including fuel and pesticides) as index contaminants. Hazard ...

Operational decision support system for large combined sewage systems: Lisbon/Tagus estuary case study
Managing combined sewage systems in large cities discharging to coastal waters, often bearing recreational activities, remains a challenge. Studying the impacts of such discharges requires the development of specific models. Hydrodynamic and water quality modelling of coastal waters employs numerical methods and algorithms, leading to the design of complex models which require expert use. The ...

Bypass Pumping System - How to choose the right pumping system to securely meet your objectives in a cost effective manner
Many bypasses are similar in appearance and name, but it’s their subtle differences that require close attention to fully understand component performance parameters. To determine the right pump, we first need to understand many different aspects of the physical conditions of the application – Flow, Lift/Pump Strength, and Distance. FLOW – is the quantity of liquid being ...

Application of water quality indices to define surface water quality in Tehran
Tehran is one of the capitals of the world that is not situated around a river, therefore surface water discharges into a network of natural streams and even some artificial canals. Owing to the lack of sewerage system, part of the sewage runs to the network of streams without any control. The aim of this work is to identify a baseline for the water quality, which will then help policy-makers and ...
