Whose Problem Is It?

asks @AbbyMPC with regards to repeatedly flooded basements and sewage overflow on a grander scale. A combination of mitigation fixes financed through the Illinois Green Infrastructure Grant program were applied to various residencies in Logan Square. Read more about the project here.

Green roofs are one approach to capturing some of the rainfall however many buildings are not able to accommodate the extra weight of wet soil. On page two of Abby’s call to action is an advertisement for an alternative that is only 15 pounds per square foot fully saturated.

Often the power consumption associated with seawater desalination is exaggerated or inaccurately represented, particularly when compared to other treatment technologies or alternatives assuring safe, reliable public water supply.

Table 2 on page 15 provides comparisons with other methods of obtaining water in California. Also mentioned is that the total power consumption of providing a family of 4 with desal treated water for a day is about the equivalent of one household refrigerator.

How new flood insurance rules might impact Fox Valley [and National] housing market - Aurora Beacon News

Essentially localities are being re-mapped in some cases to include land that wasn’t considered at risk until now. Find out if your home or a new purchase is located within the floodplain here. Note that not all rezoning has been completed.

WaterFX allows businesses to regain control over reliable access to abundant freshwater. We develop tools to ensure the consistent delivery of water for agribusinesses and other commercial water users.

By treating and reclaiming water that is otherwise unusable for irrigation or discharge, Aqua4™ offers a consistent, cost-effective and abundant source of freshwater, while transforming water management from a cost to a source of revenue. Aqua4™ is a Concentrated Solar Still that uses solar thermal energy to evaporate and distill water at 30 times the efficiency of natural evaporation. A single Aqua4 module generates 65,000 gallons of freshwater per day - 70 acre-feet per year - from wastewater, drainage water, runoff, saline groundwater and industrial process water. The remaining brine is concentrated into solid byproducts for resale.

via Chem Stack Ex… does Water Really “Go Bad” after a couple of days?

Among my friends it is a sort of ‘common wisdom’ that you should throw away water after a couple of days if it was taken from the tap and stored in a bottle outside the fridge, because it has ‘gone bad’. First of all, the couple of days is not very well defined, which already makes me a bit suspicious. Second, I cannot think of anything in tap water that would make the water undrinkable after a couple of days already.

Can someone clarify this issue for me? Does tap water really ‘go bad’ after a couple of days outside the fridge? Why?

The consensus is that generally tap water will not go bad but the many variables are discussed at length here.

Sawyer Filters Around The World

The filters are based on the technology used in kidney dialysis machines. Each filter is made up of tiny micro tubes with pores hundreds of times smaller than the diameter of a human hair. These pores remove deadly bacteria and allow only clean water to pass through for drinking. The filter effectively eliminates cholera, typhoid, E coli, amoebic dysentery, and many other bacterial contaminants. Water from rivers, ponds, puddles and rainwater can be filtered through the system and safely drunk. (x)

Securing Water For Food

Launched at the 2013 World Water Week in Stockholm, Securing Water for Food: A Grand Challenge for Development is supported by the United States Agency for International Development (USAID), the Swedish International Development Cooperation Agency (Sida), and the Ministry of Foreign Affairs of the Kingdom of The Netherlands (MFA-NL) collectively. Through Securing Water for Food, our goal is to source and accelerate innovations in the following areas that will enable the production of more food with less water and/or make more water available for food production, processing, and distribution:

  • Water Efficiency and Reusing Wastewater - especially targeted at the food value chain. This will become a greater necessity as water availability is threatened by competition between industrial, agricultural, and energy uses. Improving water efficiency and reuse has tremendous potential water-saving benefits that may have multiplier effects at various levels of a country’s economy.
  • Water Capture and Storage. These systems are in high demand in many regions where rain occurs at limited times. With projected increases in rainfall variability due to climate change and increased demands for food production, capture and storage systems at various scales are needed to secure water supplies throughout the year and build resiliency to drought and floods.
  • Salinity and Salt Water Intrusion. In coastal areas, over pumping and rising sea levels are leading to saltwater intrusion, forcing farmers to use marginal quality water for irrigation. With more than 30% of the world’s population living in coastal areas and drawing food supply from fertile deltas, urgent solutions are required to reduce the impacts of salinity on the quality of aquifers and food production.

ALSO: there’s a contest for developing deSal technology for people living on less than $2 per day.
