Global implementation of two shared socioeconomic pathways for future sanitation and wastewater flows

Households are an important source of nutrient loading to surface water. Sewage systems without or with only primary wastewater treatment are major polluters of surface water. Future emission levels will depend on population growth, urbanisation, increases in income and investments in sanitation, sewage systems and wastewater treatment plants. This study presents the results for two possible ...

Groundwater Rise Problem and Risk Evaluation in Major Cities of Arid Lands – Jedddah Case in Kingdom of Saudi Arabia

Arid lands are in the need of additional water supply but water transportation from outside of the natural hydrological cycle causes the groundwater to rise within the urban areas. Additional water supply from surrounding areas or through the desalination plants provides comfort in domestic activities but after the usage, its disposition is necessary in an efficient manner. Unfortunately, arid ...

Climate change a threat to sewage systems

Many cities could face problems with their sewage in the future. A research study for Stockholm shows that a change in precipitation, combined with a population increase, could bring disruptions as early as the middle of the century. Climate change could put more pressure on the sewage systems in the future. Climate scenarios indicate critical factors such as increased volumes of rain and rising ...

Ecofriendly Alternative to Fight Grease Build-ups

Grease traps or Grease interceptors capture the grease that goes down the kitchen drains. The simple fixture prevents slimy build up inside the drainpipes, which may result in choked drains and backflows. It is essential to cleanout these traps timely before the build up is too high to tackle. Properly maintained grease interceptors allow smooth operation of the drains by keeping the water ...
