Approximately 50-80% of residential wastewater is greywater, finding ways to reuse portions of it can reduce stress on water and wastewater treatment plants.

The City of Flint, Michigan has been in the news for having high levels of lead in its drinking water. However this problem isn’t an isolated problem, it prevails in many other cities too, such as Sebring, Ohio, Brick Township, New Jersey and more. Typically, part of the problem is caused by old pipes, through which lead can leach into water. Though congress banned lead water pipes in 1986, millions are of older lines are still in use throughout the United States. Most often problems begin with a change in the water source or treatment process changes, which alter how the water interacts with the pipes, leaving them vulnerable to leaching. Additionally, funds and budgets for water treatment are getting tighter and tighter. According to the Association of State Drinking Water Administrators, 17 states have cut drinking water budgets by more than 20%, 27 states have cut spending on full-time employees, and lastly federal officials have reduced drinking water grants.Read More
The average American uses between 80-100 gallons of water per day. But how often do we think about where it comes from or where it goes? Water infrastructure, both for drinking water and wastewater is incredibly important for our everyday lives.Read More
We can see examples of civil engineering throughout history, even though the term ‘civil engineering’ wasn’t used until the 18th century. For millennia, people have designed structures, buildings and infrastructure to serve the general public. In history, we see this starting between 4000 and 2000 BC in ancient Egypt, Mesopotamia and the Indus Valley. Many of these examples of early civil engineering achievements still exist in Egypt, China, Rome and many other places.Read More

Roads in the US are getting more crowded and congested, and the total vehicle miles traveled (VMT) hit a record high in 2016 with 3.2 trillion miles. Congestion refers to periods when the volume of traffic exceeds the road’s capacity, think about a traffic jam where cars sit idling. All over the US, congestion is getting worse, especially in urban areas. One study found that from 1980 to 2003 the total VMT increased by 111% in urban areas, while urban lane-miles only increased by 51%, which created a net effect of heavier traffic congestion.Read More
The City of Columbus has a complex sewer system made up of three types of sewers:
Combined Sewers - these carry both sewage and rain water to treatment plants, where both are treated then released into a river
Separate Sewers - these are separated sanitary (for sewage) and storm sewers
Storm Sewers - located on curbs or in drainage ditches, these sewers empty rain water (and anything carried with it) directly back into rivers.
Many cities, including Columbus, are experiencing issues with their combined and separated sanitary sewer systems, because they are often overloaded during heavy rain events. This causes combined sewers to overflow into rivers (see image below), which causes public health and ecological problems.Read More
Steve Krug once said “The one argument for accessibility that doesn’t get made nearly often enough is how extraordinarily better it makes some people’s lives. How many opportunities do we have to dramatically improve people’s lives just by doing our job a little better?” Throughout our lives our physical and mental abilities change as we age, making ability more of a spectrum than a binary concept as we once thought. By keeping this in mind as we build infrastructure, we can make infrastructure more accessible to all people regardless of where they are on the ability-spectrum.Read More
