Urban waterways are water bodies in an urban environment – either naturally occurring or deliberately designed and constructed as part of a drainage system. By channelling stormwater rapidly to a common outlet such as rivers, lakes, or bays, urban waterways play an important role in reducing flooding in the cities. Continue reading “Mitigating the effects of urbanisation on freshwater quality”
In this new age of ‘green urbanism’, innovative urban planning often includes thoughtful green solutions that bring benefit both to the community and environment.
While it is true that urban planning is more than good physical design, one can’t deny the fact that sustainable design considerations – right from the early planning phase – would lead to successful final design and construction that can significantly influence our quality of life in the cities.

Urban stormwater runoff is rainwater or snowmelt runoff that runs off the pavement, parking lots, rooftops and other impermeable surfaces in the cities. As the runoff travels to the lowest elevation, it carries with it dirt, trash, toxins and various pollutants – all the way into streams, lakes, rivers, estuaries, or oceans. This polluted runoff affects the water quality in the receiving bodies and causes significant damage to ecosystems. Continue reading “How to manage urban stormwater quality in three steps”
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”
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?”
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. Continue reading “Why an integrated approach is the key to unlocking value in urban water management”
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.
