Freeze/ thaw as a resilience issue linked to customer participation and water efficiency

Originally posted on WATEF Network 1/08/2018

"We effectively faced a major drought occurring within the space of several days – we need to have much greater engagement with customers in order to deal with all resilience issues and water efficiency is a key aspect of this."

Background and impacts More than 20,000 homes in London were without water in March 2018 due to an extreme weather event. Southern Water reported loss of supply to around 1,000 homes. Around 3,500 homes in Wales lost water supply and many parts of Birmingham, the West Midlands and Staffordshire (BBC News).
This network related event effectively led to the need for drought level responses. Londoners were told to “use as little water as possible” and to “take shorter showers”. Southern Water urged customers to “only use the water you absolutely must” (BBC News).
Ofwat recently released their report on the incident covering assessment, planning and preparation, handling o…

Water use in Tokyo

Tokyo is currently the largest city in the World with a population of over 38 million people (greater Tokyo area - 13 million in the city itself). As a megacity, Tokyo experiences a range of sustainability pressures and water management is no exception. I was recently in Tokyo for a meeting to develop the International Water Association World Water Congress programme, which is being held in September 2018. Water use and water efficiency will be a key element of the programme linked to resilience issues. I visited the Tokyo Sewerage Museum "Rainbow" to learn more about water management in the city.

Where is water used in households in Tokyo? Based on a survey by the Bureau of Waterworks in the Tokyo Metropolitan Government, average water use per person is about 230 litres per day. The highest use is flushing toilets (64l), followed by taking a bath or shower (55l) and cooking and washing dishes (53l).

The museum has an interactive household where you can actively use water a…

Walking the WSUD way in Melbourne

I wrote this blog post a while ago after a trip to Australia in 2016 but found it recently and thought it might be inspirational for those looking at solutions that can solve drought and flood risk issues. Why take a WSUD Walking tour?Every holiday needs a good walking tour, especially in a city such as Melbourne. Even better is a water themed walking tour and the City of Melbourne have several self guided tours on their website related to Water Sensitive Urban Design (WSUD).
WSUD gained in prominence as a term in Australia from the 1990s and can broadly be defined as “an approach to the planning and design of urban environments that supports healthy ecosystems, lifestyles and livelihoods through smart management of all our waters”. The WSUD scoping study for the UK presents this as the pieces of the puzzle coming together and in-practice getting first conversations started around integration is key. Linked to this is the need for evidence to support WSUD approaches and demonstrators  Fi…

Government and Ofwat pushing ahead with water efficiency

It has been just over six months since the Waterwise Water Efficiency Strategy for the UK was launched. The strategy was developed in consultation with the water sector - including Waterwise supporters and the Water UK-supported steering group. It sets out a blueprint to deliver a vision of a UK in which all people, homes and businesses are water-efficient, and where water is used wisely, every day, everywhere.

The Waterwise Leadership Group on Water Efficiency and Customer Participation has also been working to bring together senior UK water industry leaders in a more ambitious approach to wasting less water - using this to drive a more customer-led culture.

This blog post outlines some recent areas where Government and regulators are pushing ahead on water efficiency and how we plan to work with them and industry going forward.
