Annual Wastewater Treatment Plant Report

Land Harbor
NPDES #: NC0022756
Date: January 29, 2024

We are pleased to present to you this year’s Annual Wastewater Treatment Plant Report. This
report is designed to inform you about the quality of the wastewater we discharge to the
receiving water every day. Our constant goal is to protect the environmental waters of North
Carolina. We want you to understand the efforts we make to continually improve the wastewater
treatment process and protect our water resources. We are committed to ensuring the quality of
the receiving waters that we discharge to.

If you have any questions about this report or concerning your wastewater utility, please contact
CL Lewis at 828-733-8310. We want our valued customers to be informed about their
wastewater utility.

Let us first take this opportunity to give you a brief description of a Wastewater Treatment Plant.
The waters that go down the drain follow many different pipes and ends up at the treatment
plant. The wastewater goes through a bar screen that stops large particles that are present (i.e.,
rags and papers). The water then goes to an aeration basin where air is pumped into the water.
The water then goes to the clarifier where the solids settle out. The solids are pumped back to
the aeration basin to give the bacteria a second chance to feed. When there are too many solids
in the plant, some of the solids are pumped to a digester tank. In the digester, the bacteria have
more time to feed on and reduce the solids’ volume. When the digester gets full, the solids are
pumped from the tank and taken to a larger facility. The clear water from the clarifier then goes
to a tank for disinfection. The two most prominent ways to disinfect wastewater are chlorine and
ultraviolet light. Chlorine can be used as a gas or in solid tablet form. When chlorine is used,
there is generally a dechlorinating agent used to remove any excess chlorine from the wastewater
before it goes to the receiving water. When ultraviolet light (UV) is used, the wastewater flows
around the UV bulbs. Bacteria can not live when exposed to UV light, so as the water passes the
UV bulbs, the water is disinfected. Finally, after disinfection, the treated wastewater goes into
the receiving waters.
PERFORMANCE

The treatment plant did very well last year. The plant was compliant with all of the limits set by
the State of North Carolina and the permit for the entire year.
