It happens with every new presidential administration in modern times, the promise to “do more about the nation’s infrastructure problems.” But what happens after these words are spoken? Who becomes the voice of the people and makes sure that these promises are kept? The U.S. Conference of Mayors plays a major role in not just ensuring that administrations “make good” on the promises, but in helping to shape infrastructure plans and make the most efficient, effective use of federal funding.
Every day you hear things like “push your data into the cloud” or the newest functions of “cloud computing”. But what does this all mean? And what does it mean for utilities and facilities? Well, if you’re looking into Cloud SCADA, it can mean then difference between having to purchase and maintain software and hardware versus utilizing the internet and cloud computing platforms to serve as the framework for your SCADA system. That translates into time and money saved in the long run.

When first moved from water reservoirs, water contains materials that need to be treated and or removed. All microorganisms, flora and fauna waste, assorted dirt and insects all need to be dealt with before, water is fit for human consumption. It is understood that, water needs to make many detours in its path from raw supplies to the tap. All these detours start at the treatment plant. At the plant water goes though applications that remove contaminants such as suspended solids, bacteria, algae, fungi, and minerals such as iron and manganese. The final objective is to turn contaminated debris choked water into safe, drinking water.

Recreational ponds, wastewater lagoons, fish grow-out ponds and small, shallow lakes have always exhibited the problem of organic matter collecting on the bottom and eventually becoming polluted. Wastewater lagoons are especially fraught with problems because their purpose is to clean the wastewater to the point that it can be released back into the environment. Over the years many different things have been attempted to assist in degrading the organic matter that builds up in the “sludge” on the bottom of these water bodies.
