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 can humans contribute to ecosystem services?

Ecosystem services are defined as services provided by nature to humans. This straightforward definition suggests a passive role for humans as receivers of the outputs of nature. However, there is also an active role for people to play in providing these services. Continue reading “How can humans contribute to ecosystem services?”

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”

Wastewater treatment: How can Digital Twin modelling play a crucial role in WWTP operations?

Digitalisation is a term and process that is frequently stumbled upon in business settings. At its core, one could argue that digitalisation refers to the use of digital technologies to provide new valuable and important opportunities. But how does digitalisation play a role in the operation of wastewater treatment plants (WWTPs)? Which positive impacts can digitalisation have on the Water Industry? Continue reading “Wastewater treatment: How can Digital Twin modelling play a crucial role in WWTP operations?”

Why an integrated approach is the key to unlocking value in urban water management

Today, cities all over the world are dealing with a range of global pressures such as rapid urban growth, severe climate changes and aging infrastructure to provide safe and resilient water supply, collect sewage, secure a minimum spill of untreated water and reduce risks of flooding. Because of these challenges, cities experience difficulties in finding efficient and sustainable ways to manage water. Continue reading “Why an integrated approach is the key to unlocking value in urban water management”

Water distribution: How new technologies can help preserve and improve drinking water quality

As water is seen as one of the world’s most precious resources, providing enough water with appropriate quality and quantity may be considered as one of the most important challenges in human history.

The world is, as we speak, experiencing serious growth in urban population. This, together with water scarcity and shortage due to climate changes, are creating massive challenges for urban water management. Continue reading “Water distribution: How new technologies can help preserve and improve drinking water quality”

How Cloud solutions can help cities predict flash floods more accurately

Heavy rainfall and floods impose considerable consequences to communities and infrastructure, resulting in death or injury, affecting livelihood, damaging roads, property, water networks and more.

According to a United Nations report, in the ten years from 1995 to 2015, floods accounted for 43% of all documented natural disasters, affecting 2.3 billion people, killing 157,000 and causing US$662 billion in damage. The UNESCO World Development Report further states that climate change, increasing population, loss of wetlands and rising sea levels are expected put 2 billion people at risk of flood disasters by 2050. Continue reading “How Cloud solutions can help cities predict flash floods more accurately”

Ways to permanently reduce non-revenue water levels

High leakage levels, inefficient pipe network maintenance, customer complaints and financial losses are some of the top challenges of water utilities. Many of these troubles can be effectively countered – if you know how to nip the problem at the bud by dealing with the issue of non-revenue water (NRW).

NRW is water that has been produced but cannot be billed. The loss can be the result of leakage or overflow (sometimes referred to as physical losses), theft of water or inaccurate metering (also known as apparent losses), or free use (for example, for firefighting). Calculations suggest that more than US$14 billion is lost every year by water utilities around the world due to NRW. The World Bank recommends that NRW should be less than 25% of the total water produced, while in many countries NRW is up to 60%. High levels of NRW are detrimental to the financial viability of water utilities and pose an extra burden on paying customers. Continue reading “Ways to permanently reduce non-revenue water levels”

Best practices for successful coastal flooding adaptation

Global warming, rising sea levels and rapidly growing cities are placing immense pressure on coastal cities, towns and subsistence communities. The U.S. Population Reference Bureau estimates that almost 6 billion people will be living within 200 kilometres of a coastline by 2025 – close to double the number in 2003. Population growth – along with sea level rise compounded by storm surges and increased rainfall intensity due to climate change – are the key reasons for the increase in coastal flooding and the degradation of our coastal regions and ecosystems today. Continue reading “Best practices for successful coastal flooding adaptation”

How to reduce inflow and infiltration in a wastewater network

Stormwater ingress to a city’s sewer system through low gully traps, illegal connections, broken pipes or unsealed manholes is known as Inflow and Infiltration (I&I). This can cause overflows, system strains and interruptions.

What is Inflow & Infiltration? 

Inflow: Stormwater that enters the wastewater network directly through gully traps, roofs or illegal connections.

Infiltration: Stormwater or groundwater that enters the wastewater network through cracked pipes and leaky or faulty manholes.
