Special to New York Construction Report
Born out of the idea to launch of an environmentally friendly construction business, Concrete Washout Systems (CWS) is a portable self-contained and watertight roll-off bin that controls, captures and contains concrete washout and runoff. CWS makes it easy to wash out concrete trucks, pumps and equipment on-site, facilitating easy off-site recycling of the same concrete materials and wastewater.
Capturing and recycling washout just isn’t a ’green’ thing to do, it’s a legal requirement, and builders ignore that at their own peril. The fines are pretty steep, cautions Roger Haftek, CEO of Concrete Washout Systems.
In New York City, not properly handling concrete washout can result in a fine of $6,000 a day. The city’s local law 70 requires a builder or developer or anyone pouring concrete to utilize a manufactured container, specifically for the purpose of collecting concrete washout.
Dumping concrete washout, or handling it inefficiently can be costly in terms of fines– as much as $15,000 a day, but it’s also damaging to the environment, says Haftek. The material inherently has a high PH, a measure of how acidic or alkaline a substance is, a value of 12, and contains a range of corrosive chemicals. It’s like pouring ammonia, oven cleaner or a liquid drain clearing product directly into the ground.
The pH scale goes from 0 to 14, where 7 is neutral. A change in one pH unit means a tenfold change in concentration, similar to the Richter scale and measuring earthquakes, CWS explains on its website. High pH levels are damaging to fish and vegetation, with effects including inhibited growth, damage to soil and plants and substantial alteration of the soil and plant chemical composition even after the pollution source is gone.
CWS takes the material to its treatment plant, reducing it to a pH value of seven. The heavy metals and solids are removed, and it becomes clean, reusable water that is delivered to the Passaic Valley Sewage Commission.
Despite the sanctions that can be applied for not handling concrete washout responsibly, and the environmental damage that can be done from letting it spill, some builders still try to cut corners, hoping they can get away with it. Many still do, says Haftek.
“One of the benefits of working with us is, obviously, that people would comply with the law. The second benefit is that a lot of people use homemade contraptions, or maybe just dump the stuff on the ground, and they hope they don’t get caught. We recycle everything we take … no waste at all going to a landfill.”
Trained drivers deliver the washout containers to a building site. When the containers are full, the drivers remove and replace them as required. Unfortunately, says Haftek, his biggest competition still comes from people just dumping this caustic material on the ground. Much of it comes down to a lack of enforcement.
Related to our own mission, we support grassroots organizations who play a major role in making citizen’s more aware of the importance of clean water and how they can directly help in these efforts. “CWS believes it’s important and are proud to support advocacy groups, such as The Hackensack Riverkeeper and participate their annual EarthFest Overpeck, a celebration of clean water and a healthy environment, through a partnership between Hackensack Riverkeeper and Bergen County Parks.
