Sustainable water supply systems are a core necessity for both urban and rural planning and development. The need for potable and domestic water spans across the entire spectrum. Rural needs are additionally about agricultural usage, while urban areas must manage industrial and commercial requirements.
The socio-economic and environmental issues associated with both the supply and demand aspects vary vastly for urban and rural communities. Many such factors categorized under usage or watershed management depend on the climate, availability of natural resources, and the population level and growth rate. The one common fact every community must face is that they cannot grow or even survive without aqua.
On the supply side, watershed management requires a lot of planning and resources. The key is finding the right balance between the needs of the human population and maintaining the natural ecosystem. Practical work that comes under this includes water rights, cross-jurisdiction agreements, land use, stormwater runoff, drainage, and compliance with environment law.
Surface freshwater is not evenly distributed. For instance, Canada owns more than half the lake freshwater in the world, so everyone else has been forced to build dams to block rivers and create giant artificial reservoirs. The main source for communities which do not have surface supplies is groundwater, which accounts for more than 50% of the world's total amount of freshwater.
Rainwater harvesting systems are highly sustainable. There is no risk of depletion or contamination, since it is not overexploited and the source is clean enough for direct human consumption. The only thing limiting wider usage is the implementation cost, and the cost of treatment required to prevent contamination of stored rainwater.
Desalination plants are also leave the existing supply of freshwater untouched. Removing salt from seawater is not as environment-friendly as collecting rainwater, although it is far better than blocking rivers with dams and pumping out all the groundwater. The main barriers are the setup cost and the energy usage required for the reverse osmosis process. There's also the fact that desalination plants produce Co2 emissions and other byproducts that can harm marine life.
Other ways to ensure sustainability on the demand side include reduction in wastewater generation. This means innovation to reduce consumption by installing dual flush toilets, astroturfs, artificial lawns, waterless car washes and other such systems. Better and wider implementation of wastewater treatment systems will help, as will improving the efficiency of municipal distribution pipes to reduce leakage.
All of these aforementioned methods and aspects are just the core components of the overall mission of implementing sustainable water supply systems. Ultimately, what it needs is a major technological revolution accompanied by cross-jurisdictional cooperation and regulation updates to ensure sustainability of every community. WHO estimates that around 1.8 million die each year from consumption of contaminated water, and it is increasingly worse because of severe floods and droughts triggered by climate change. It follows that the first order of business should be to ensure a safe and adequate supply of potable water.
