Yesterday, the Great Bend Public Utilities Department welcomed residents and members of city council out to the wastewater treatment plant for a tour of the facility. Attendees learned about the operations and processes the plant undergoes to clean and treat wastewater.
Wastewater is any water that's been used in homes, industries, or businesses and contains a mixture of human waste, chemicals, bacteria, fats, and other materials that make it unsafe for a direct discharge into the Arkansas River. The City of Great Bendβs plant receives waste from 21 lift stations and 400,000 linear feet or 76 MILES of sewer mainline pipe. It averages 1-1.2 million gallons of wastewater every day and operates 24/7, 365 days of the year!
There are five main stages of treatment at the plant:
β’ Preliminary Treatment β Removes large debris, rags, sand, grit, grease, and other materials from incoming wastewater to protect pumps and downstream equipment.
β’ Primary Treatment β A biological process where microorganisms (βbugsβ) consume and break down dissolved and suspended organic material.
β’ Secondary Treatment β A physical settling process where wastewater is held in clarifiers so heavier solids settle to the bottom as sludge and lighter materials such as grease and scum float to the surface for removal.
β’ Tertiary Treatment β Advanced treatment that further improves effluent quality by removing nutrients, fine solids, pathogens, color, and other remaining contaminants.
β’ Sludge Treatment β Stabilizes, thickens, dewaters, and prepares sludge/biosolids for disposal.
More than 99.9% of what goes down drains and toilets is water. Only 0.01% consists of solids, organic material, nutrients, and other contaminants. The wastewater treatment plant removes those pollutants and safely returns treated water to the environment, protecting public health and reducing pollution in our rivers and streams.
Thank you to everyone who took the time to come out and learn how the wastewater treatment plant and Public Utilities Department play an essential role in protecting the health and environment of Great Bend.
