Lehigh County Authority Employees Win Two Wastewater Treatment Awards

LCA was honored with two awards from the Eastern Pennsylvania Water Pollution Control Operators Association earlier this month. The first award, for Industrial Pretreatment, recognizes the staff at LCA’s Industrial Pretreatment Plant in Fogelsville and The Kline’s Island Wastewater Treatment Plant in Allentown for their diligent work to meet the requirements of the EPA-mandated pretreatment…

Cold Weather Is Here — Protect Those Pipes and Meters From Freezing!

All the water meters in the picture above needed to be replaced because they froze. With more cold weather on the way, it’s important to protect your pipes and meters.   With just a little over a month before the official start of winter (Dec. 21), we’re already seeing temperatures that seem to indicate the…

LCA Wins Water Quality Award for 12th Year in a Row

Congratulations to our great Water Filtration Plant team for receiving the Area Wide Optimization Program (AWOP) Award for the twelfth year in a row! The award is presented to participants that meet the American Water Works Association Partnership program’s water quality standards, which are much more stringent than standards set in place by the state Department…

On Oct. 23, Imagine a Day Without Water

Can you imagine a day without water? No showers, no morning coffee, no working toilets — not even water for putting out fires. For some people, living without water is a daily reality. Yet most of us take for granted that when we turn on the tap, clean, drinkable water will flow out. That’s why…

Disinfection and Testing — the Final Steps in Wastewater Treatment

Over the past several months, we’ve talked about why wastewater must be treated, and detailed each step in the treatment process at Allentown’s Kline’s Island Wastewater Treatment Plant. Now we’ve come to the final treatment step: disinfection, in which we use a chlorine solution to kill pathogenic (disease-causing) microorganisms before the wastewater is released into…

Tertiary Nitrification: How Ammonia Is Removed From Wastewater

In our last post, we explained how plastic media filters remove contaminants during secondary treatment. Today we’re going to talk about the next level of treatment, which removes ammonia through a process called tertiary nitrification. As you can see from the picture above, it’s probably not what you imagine when you think of water treatment!…

How Is Liquid Waste Treated? It’s All About Biology

As 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

LCA 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…
