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?”
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.

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”
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.
