Sustainable cities, or “smart” cities, focus economic and technological resources on conserving water, improving energy efficiency, reducing waste and enhancing their citizens’ quality of life. Innovations for renewable energy, the development of efficient waste management systems and community planning for smart growth ensure the viability of cities for years to come.
Critical Water Conservation Planning
Cities striving for sustainability must address water supply issues based on population demand. According to the United Nations, a 3-4 degree Celsius rise in global temperatures by 2080 could place an additional 1.8 billion people in water-scarce environments. Municipalities must be able to maintain freshwater resources through conservation, treatment and recycling.
The city of Philadelphia has made inroads toward water sustainability through its “Green City, Clean Waters” plan. One of its goals is to protect the municipal water supply from stormwater runoff pollution. The plan calls for green, low-impact development to limit paved areas, which block runoff absorption. Additionally, Philadelphia has formally partnered with the EPA to develop new water handling strategies based on hydrologic and hydraulic models. — Full Story at TriplePundit —
