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.

Why empathy is the key to providing a great customer experience

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”

What has climate change got to do with increased groundwater salinity?

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.

Can nature provide the solutions for better water management?

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. Continue reading “Can nature provide the solutions for better water management?”

Creating positive environmental impacts with artificial reefs

How to recover good environmental status with new marine habitats

Marine structures – such as piers, windmills and bridges – typically have a bad name when it comes to their effects on the environment. But did you know that their existence could impact marine environments positively too? Continue reading “Creating positive environmental impacts with artificial reefs”

Global Wind Day: How do wind turbines work?

Celebrating the power of wind

Thanks to global efforts and agreements such as the United Nations Framework Convention on Climate Change (UNFCCC) in tackling climate change, we are observing a boom in renewable energy growth, especially in wind energy. Continue reading “Global Wind Day: How do wind turbines work?”

Using EMMP to proactively manage and protect the environment

Rapid coastal development, combined with population growth and global industrialisation, is placing coastal and marine environments under increasing pressure. New ports and harbours, coastal defence and climate change adaptation measures, as well as land reclamation and dredging works are imperative in order to support our existing and future economy. Continue reading “Using EMMP to proactively manage and protect the environment”

8 cool facts about Planet Earth that might be new to you

Earth Day is an event celebrated on 22 April every year. Globally, various events are organised to demonstrate support for environmental conservation. First celebrated in 1970, Earth Day has come a long way – with over 190 countries now coordinated worldwide by the Earth Day Network.
