Slope Whisperers

Cambridge, MA, maintains a series of three terminal reservoirs for drinking water. Fresh Pond has been one of the most prominent reservoirs in the city’s fleet of water sources and a favorite with the community, not just as a source of water, but also because of its role as a

Hard-Armor Options for Protecting Roads and Bridges

Hard-Armor Options for Protecting Roads and Bridges

Hard-armor products are valuable tools in the tool chest of experts in erosion control and stormwater management. For some applications, softer alternatives such as erosion control blankets, turf reinforcement mats, and vegetation are appropriate. But many roads, bridges, and streambanks face destruction because of undercutting due to runoff or high

A Wave of Innovation

A Wave of Innovation

Wastewater treatment plants are impacted by the same infrastructure issues as highways, bridges, and municipal water systems. As population increases and permitting requirements are strengthened, there is little room to upgrade and expand. Costs are also prohibitive. New technologies like membrane bioreactors (MBR), however, can fit in the footprint of

Backflow Prevention Methods

Backflow Prevention Methods

Without a source of clean, safe water, neither individuals nor communities can survive. So perhaps the greatest invention of any civilization is a way to ensure clean, safe water. Supplying clean, potable water is both complicated and straightforward. The actual process is a relatively simple series of steps (extraction from

Stormwater Monitoring

Stormwater Monitoring

The most dramatic and identifying characteristic of water is that it is always moving. Even so-called standing water is never completely static; it’s either being drawn by gravity to seep down into the earth or being agitated by warmth at the surface to rise into the air as a vapor.

Pump System Longevity and Extreme Operating Regimes

Pump System Longevity and Extreme Operating Regimes

A pump is a mechanism that utilizes mechanical force to overcome distance, elevation, and friction to move water or another liquid through a conduit to a point where it can be discharged, stored, or utilized. Like all mechanical devices, pumps can wear out or break over time. A pump’s operational

Pumps Operations in the Building Envelope

Pumps Operations in the Building Envelope

Water flows downhill. Nothing could be more simple. Getting water to the top floor of an urban skyscraper is a bit more difficult. Mere gravity flow or even accumulated static pressure head aren’t sufficient to accomplish this task. Pumps are obviously needed. But what kinds of pumps are used in
