Ennesys, a Paris-based energy systems company and OriginOil,
an American algae harvesting company just unveiled their new urban
algae demonstration project in La Defense, near Paris. The revolutionary
system harvests energy from algae present in wastewater while filtering
the wastewater for use as graywater.

The destruction caused by Hurricane Katrina in 2005 has forever impacted the Gulf Coast. The devastation and subsequent rebuilding has led to a shift in ideology from just simply “building back” to “building better” to reduce the impact of a similar storm in the future.
The Jackson County Utility Authority, hard hit by the storm, recently began development of decentralized wastewater infrastructure in Big Point and Wade, Miss. Neel-Schaffer Engineering of Jackson, Miss., was selected as the design engineer for the projects. The firm selected a fixed film media filter as the technology of choice to provide advanced wastewater treatment, followed by drip irrigation to disperse the highly-treated wastewater back into the environment.
France-based water company Veolia Water’s subsidiary MSE has won a contract from the Vienne Water and Wastewater Authority (SIVEER) to construct a wastewater facility based on its Organica system.
The plant will be built in Les Trois-Moutiers commune, in the Poitou-Charentes region in western France, to treat wastewater from Les Trois Moutiers and Vienne Center Parcs holiday village.
The wastewater facility has been designed with a capacity for 8,000 people, of which 6,500 is for Center Parcs.
The Organica system blends conventional wastewater treatment technology with an ecosystem.
As part of the technology, the roots of plants are grown under a glasshouse and running up to depths of 1.5m into the effluent to promote the growth of bacteria and living organisms to treat the effluent.
The facility will treat contamination in wastewater, while consuming less energy compared to a conventional wastewater plant.
The United States has many different climate zones and topographic and geographic features. Each state and even areas within states differ in their ability to support different plant species without the need for supplemental water and fertilizers. The following plant lists will help you identify plants appropriate for your location. When designing your landscape for water-efficiency, be sure to choose plants that are defined as low water use or drought tolerant for your area. These plant species will be able to survive in your climate with minimal, if any, need for supplemental watering. See these simple tips for water-efficient landscaping for more ideas on lowering water use in your yard.
SepticSmart Home | Septic Onsite / Decentralized Systems | US EPA. Welcome to SepticSmart!Did you know that one-quarter of all U.S. homes have septic systems? Yours may be one of them. If you’re not properly maintaining your septic system, you’re not only hurting the environment, you’re putting your family’s health at risk—and may be flushing thousands of dollars down the drain.
EPA’s SepticSmart initiative is a nation-wide public education effort that aims to inform homeowners living on properties serviced by septic systems on the importance of properly maintaining their septic system and provide valuable resources to help homeowners make important decisions regarding their wastewater management needs. The initiative also provides resources for outreach organizations and government leaders who seek promote this message locally.

“Homes. schools, trains, and public buildings all provided common drinking cups as had been the tradition for centuries in Europe and America. This custom especially aroused Dr. Crumbine’s ire [Samuel J. Crumbine was a public health advocate and member of the Kansas State Board of Health].
