Water Management Lessons Learnt from Day Zero
Water Management is critical for effective management both in our locality, nationally as well as on a global water.
Firstly for those who have done their research you will have probably come across Day Zero which relates to a point in a cities management where it runs out of water which it can provide to its population.
Now water is this fantastic resource that everything relies on a depends on but to much or to little can cause problematic situations to arise. In the UK last week we had some of the heaviest downpours of the recent year in quick succession leading to flooding in areas which have faced drought conditions for a prolonged period. Now the water courses and drainage basins receiving a much needed resupply was crucial for the flora and fauna of these areas. The question is how do we best manage these water courses in our local areas.
Sarni, (2020) writes that Day Zero as a principle is flawed this concept is something that will be discussed further in the article. Initially the concept comes out of a situation in 2018 in Cape Town where after continual droughts for 3 years. The aim was to ration the water available to the community. Yet the warning of being wasteful with water was enough to change the consumers habits. Now whilst they did not have to restrict water, there was a lack of strategy with this action and more a lucky perfect storm of circumstances. Statistically as our climate changes and historic data is less reliable than it has been. This also highlights a problem that we need to address, is complacency until the challenge is staring us in the face we often do not adjust our habits until we have to a proactive approach is necessary to conserve the resource. Continued population growth is likely to increase demand not only abroad but in the UK as well as we see an increased demand for water both in agriculture and residential purposes. Other industries also need to reflect on water usage the fashion and textile sector is also seeing step changed to a more conservation focused to water management particularly some denim producers. Sarni (2020) particularly highlights that as demand for water increases the impact on those in our society will be more profound.
Edmond, (2020) points out that part of the problem is rapid urbanisation. Urban areas can both displace water and if not correctly planned prevent water being conserved. Planning urban areas with water conservation tools such as water less sanitation where possible. Better habits for conserving water and recycling of grey water. Vancouver increases the cost of water at different times of the year to reduce excessive consumption this is a measurable increase not overtly affecting core needs for water. Levying this against excessive uses such as key businesses or even residential. Australia uses water efficiency management strategies on high use buildings similar to other forms of gradings to improve efficiency and effective use. Both Dubai and Ireland have looked at education to embed water conservation at the heart of education.
By designing our urban and rural planning systems to collect and store water more effectively to both enable better drought reduction as well as safer by avoiding water build up on roads. By having roofs which collect excess water and slows the rate the water enters the water course as well as where feasible using water storage systems like boreholes or miniature reservoirs which store the excess water. This coupled with earlier points made about trees in earlier articles can better protect our urban areas and provide better access to the community to flood protection and water availability.
