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.

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?”
The rapid pace of development in coastal areas often comes at an environmental and ecological cost, with the accelerated loss of coastal nearshore habitats such as seagrass meadows and mangrove forests. However, the presence of these nearshore coastal habitats play an important role in the maintenance of resilience of coastal cities and populations. They confer resilience via ecosystem services such as carbon sequestration, moderation of natural hazards and nutrient cycling. There is a recognised and urgent need to stem the loss of these valuable habitats in balance with infrastructure development and economic needs.

Unsure about the similarities and differences between artificial intelligence, machine learning and deep learning? This blog post introduces the quick basics. Continue reading “The very basics of artificial intelligence, machine learning and deep learning”
A vast amount of the plastic that is produced for packaging purposes is used for storing food. Considering both the waste generated and the resources spent to produce packaging, it is only common sense to recycle some of this plastic for new food packaging. Moreover, circular economy is a focal point in the EU, and in 2025, the extended producer responsibility should result in more recycling. Continue reading “How to safely recycle plastic waste into new food packaging”
According to the Cambridge dictionary, customer service is ‘the way that an organisation deals with customers before, during, and after a sale, and the activities involved in dealing with customers.’
Technically, the above is right. But these actions will not result in a great customer experience without empathy. Continue reading “Why empathy is the key to providing a great customer experience”
Compliance with regulatory requirements increasingly demands clear evidence on how birds behave within and around wind farms. To meet this demand, automated multi-sensor monitoring systems such as MUSE have been developed to provide robust data on real-life bird behaviour at and within wind farms. The MUSE system is based on integrated radar and digital camera(s) and was developed during a four-year pioneering investigation on seabird behaviour at offshore wind turbines; the Carbon Trust Bird Collision Avoidance Study 2014-2017.

Rising sea levels due to climate change is affecting us more than we know
Sea level rise due to climate change is one of the contributing factors of salinity intrusion, particularly for shallow sandy aquifers in water stressed coastal areas. In many of such areas surface water salinity is additionally increased due to reduced upstream discharges and salinity can intrude both directly from the sea and from the surface waters. Furthermore, a temporarily rise in sea level can be caused by various acts of nature, such as tsunamis and hurricanes bringing about storm surges. Due to ongoing evaporation, the salt concentration of water in sandy aquifers have the potential to increase exponentially and eventually cause contamination or environmental problems. Continue reading “What has climate change got to do with increased groundwater salinity?”
With an increasing number of satellites launched in recent years and advances in the image analysis methods, remote sensing data has proven itself as a cheap and very valuable source of information for planning, construction and monitoring of offshore wind farms (OWF). Continue reading “Satellites and offshore wind farms? A match made in space”
Nature-based solutions are water management interventions that make targeted use of ecosystems to deliver specific water management benefits. With communities around the world increasingly facing risks and impacts due to population growth, urbanisation and climate change, nature-based solutions have a lot to offer in support of sustainable and affordable water management.
