The one tip for an efficient wastewater treatment plant: Go digital

According to the Water and Wastewater Systems Sector analysis conducted by the U.S. Department of Homeland Security, there are 16,000 municipal wastewater treatment plants (WWTPs) in the US. Additionally, there are another 18,000 WWTPs in Europe according to EurEau. Continue reading “The one tip for an efficient wastewater treatment plant: Go digital”

How real-time modelling supports a proactive water network operation

With rapid urban population growth, water utilities worldwide are more than ever facing pressing challenges to preserve the hydraulic perfomance and water quality of already strained water distribution networks and infrastructure. Continue reading “How real-time modelling supports a proactive water network operation”

Is the darkest place under the candlelight?

Potential problems with insufficient water circulation in water tower tanks

Many would assume that water quality is best in the storage tank or near the tank. While that is often the case, there are exceptions where this might be the opposite. Continue reading “Is the darkest place under the candlelight?”

Is the water quality of your network affected by the PVC in plastic pipes?

Analyse the cumulative contact time with a new computational method

The role of hydraulic models in risk assessment analysis

Most hydraulic models provide a ‘water age’ option that allows users to calculate the residence time of water within the pipe network. While this is a standard water quality indicator used in practice, it does not address the issue when we need to analyse the contact time with pipes of a specific material, such as polyvinyl chloride (PVC). Continue reading “Is the water quality of your network affected by the PVC in plastic pipes?”

How to conduct fire flow assessments for your water distribution system

Avoid the mistake of having a poorly thought-out fire protection plan

‘For centuries, water has been used to extinguish fires. The inexpensiveness and availability of water are the primary factors leading to its widespread use. But, not only must water be available for fire protection, it must be available in adequate supply. As a result, the question must be asked, how much water is necessary to be considered an adequate supply for fire protection?’
