How Is Liquid Waste Treated? It’s All About Biology
September 16, 2019As part of our ongoing series explaining the wastewater treatment process, we’ve discussed how solids are removed from wastewater, how we use waste to create energy, what happens to the byproducts of treatment, and even what happens to things that should not be flushed. Now we’re going to explain what happens to the liquid waste:…
Fire Hydrant Maintenance — Yup, We Do That, Too
August 23, 2019LCA crews have been hard at work this summer, flushing, painting and repairing hydrants throughout the city of Allentown. Maintaining hydrants is an important and ongoing task. Our crews inspect and test over 900 hydrants every year so that they’re in peak condition in case the fire department needs them. We look for leaks, check…
The Sludge Report: What Happens After Treatment?
June 19, 2019If you’re a regular visitor, you’ll know we’ve been doing a series of posts explaining how wastewater is treated. In our last post, we talked about why it needs to be treated — and what happens when it’s not. Today, we’re going to discuss one of the byproducts of treatment: sewage sludge. Sewage sludge is a…
Kline’s Island Gets New Electrical Substation as Part of Infrastructure Update
May 14, 2019The new Kline’s Island substation, above, includes provisions for additional power demands in the future. It’s National Infrastructure Week — a time to #BuildForTomorrow and “highlight the state of our nation’s infrastructure – roads, bridges, rail, ports, airports, water and sewer systems, the energy grid, telecoms, and more.” We usually think of water infrastructure…
Why Does Wastewater Need to be Treated?
May 1, 2019Above, untreated wastewater pollutes a waterway in India. If you’ve been following along, you’ll know we’ve been doing a series of posts explaining how wastewater is treated. In our last one, we talked about how solids are removed from wastewater, then sent to the primary settling tanks for stabilization and treatment. What we haven’t covered…
Sludge 101: How Solids Are Removed From Wastewater
April 5, 2019Ever been curious about how water gets to your tap? Ever wonder what happens after you flush the toilet? Join us for our series of semi-regular posts in which to try to demystify the process. This is our fourth in the series. In our last post, we talked about the screening process — how we get…
Wastewater Treatment Starts with Screening Out Items That Don’t Belong
March 14, 2019As long as everything works the way it’s intended, most of us take for granted the water and wastewater services we use every day. But have you ever been curious about how water gets to your tap? Ever wonder what happens after you flush the toilet? Through a series of semi-regular posts, we’re going to…
Clean and Green: How Waste is Turned into Energy at Kline’s Island
February 27, 2019Did you know that bacteria are hard at work producing between 35 and 50 percent of the electricity required to treat Allentown’s wastewater? That’s because they’re helping create renewable energy used to fuel a biogas generator, which in turn supplies electricity and heat at LCA’s Kline’s Island Wastewater Treatment Plant. Here’s how it works: Biogas…
