Poo-Gloos provide a large surface area on which bacteria can grow, providing the microbes with air and a dark environment so they consume wastewater pollutants continuously with minimal competition from algae.

Sewage-eating ‘Poo-Gloos’ can help small communities expand wastewater treatment capacity
Wastewater treatment in small, rural communities is an important and challenging engineering task. Proper treatment includes disinfection and the removal of unwanted pollutants. Most rural communities rely on wastewater lagoons as their primary method of treatment because they are simple and inexpensive to operate. But as communities grow and pollution discharge requirements become more stringent, typical wastewater lagoons no longer can provide adequate treatment. Until now, the only alternative for these communities was to replace lagoons with mechanical treatment plants, which are expensive to build and operate. However, a new study claims that inexpensive, igloo-shaped, submerged bio-reactors nicknamed “Poo-Gloos” can clean up sewage just as effectively as multimillion-dollar treatment facilities for towns outgrowing their waste-treatment lagoons. The devices, also called Bio-Domes, were developed by civil and environmental engineering researchers at the University of Utah.

Monitoring a high-speed rail project in Barcelona
One of the last big projects on the high-speed rail link connecting Madrid to the European high-speed rail network is the La Sagrera station in Barcelona, an underground facility expected to handle 100 million travelers per year. In order to prevent damage to homes, businesses, and historic structures near or above the construction sites, engineers are using high-precision Trimble S8 Total Stations to measure thousands of points in the construction zone. The total stations, which are robotic and controlled remotely from a central office, provide millimeter precision in detecting motion on hundreds of buildings and structures. All of the measurement data is managed at a single location, and alerts to motion are automatically sent to project managers’ smart phones. To read the full article, click here.

Strategic success in planning for the downturn
After a decade of strong growth, it didn’t take an economist to know that an economic downturn was on the horizon. The question is, how many executives saw it coming and planned ahead?

Psomas prepared for the downturn by diversifying into new markets. As a result, the firm was awarded two major renewable energy contracts in California — one involving the largest school solar power installation to date in the state.

This article will explain how Psomas executives anticipated the downturn, which diversification strategies were evaluated, the PsomasFMG business model the firm developed, and valuable lessons learned. To read the full article, click  here.
