Water Treatment Plant

General Information

The Harrodsburg Water Treatment Plant was originally constructed in 1956 at its current location of 3025 Shakertown Road.  The source of water for Harrodsburg is above Lock 7 of the Kentucky River and below the confluence of Dix River.  The plant was upgraded in 1980 to produce 4.0 MGD (Million Gallons per Day); including a new River Intake Pumping Station, a new raw water main, along with new finished water mains into the distribution system.  The plant was designed as a “high rate conventional treatment” facility.

With continued growth in Mercer County and Harrodsburg, the plant was once again upgraded in 2012 to its current treatment capacity of 6.0 MGD.  The project included a new filtration building with two additional filters, a new chemical storage building, a new coagulation and sedimentation basin, and a new high service and backwash pump station atop a new 600,000-gallon clearwell.  The latest upgrade has been to improve the computer-controlled instrumentation system, called SCADA (Supervisory Control and Data Acquisition) in 2016.  The system allows operators to monitor and control a multitude of treatment parameters via PC or smartphone.

Harrodsburg Water Treatment Plant currently provides water to the City of Harrodsburg, the City of Burgin, Lake Village Water District and North Mercer Water District for a total of nearly 26,000 residents.  Our distribution system consists of over 100 miles of water lines, three 750,000 to 1-Million-gallon water tanks, over 4200 water meters and 450 fire hydrants.

Facility and Operations

Harrodsburg’s water treatment plant consists of a conventional turbidity removal facility that utilizes chemical coagulation and mechanical flocculation, settling and filtration to remove suspended particles from raw water.

Raw Water Intake – Untreated water is gravity fed from one of two intake silos from Kentucky River, which is then pumped into the River Station via submersible pumps.  Water is then pumped nearly 250 vertical feet to the plant for treatment by one of two vertical turbine pumps at a rate of 4100 gallons per minute (GPM).

Chemical Mix Basin – The raw water enters a high energy flash mixing basin where it is treated with several chemicals for a variety of purposes.  The primary coagulant, added to aid in the removal of fine suspended solids, is a poly-aluminum chloride.  The coagulant increases particle size and weight and improves gravity settling prior to filtration.

Powder Activated Carbon may also be fed seasonally to aid in the removal of organics and algae, reducing taste and/or odor, disinfection by-products (DBP’s), and Total Organic Carbons (TOC’s) precursors.

Chlorine gas is used to disinfect the raw water before and after filtration, as it contains one of the best residual safeguards in the distribution system.  The treated water then flows in a serpentine pattern through the sedimentation basin allowing for particles to gravity settle out of the water.

Filtration and Finished Water Storage    

Once treated water leaves the sedimentation basin, it enters the filtration building and receives a dose of filter aid; a cationic polymer that aids in the formation of large easily settleable floc particles and helps with the adhesion to the filter media.  Water gravity flows into six “mixed media” filters containing anthracite, sand, gravel and is fed into two 600,000-gallon underground storage reservoirs called “clearwells” for a total of 1.2 million gallons (MG).  As the water flows down through the media the remaining solids becomes entrapped between the particles; the final stage in solids removal.  At routine intervals the filters will be cleaned and captured solids, by the reverse flow of finished water at high velocities, known as “filter backwashing”.

Before entering the clearwell the water is treated with Hydrofluosilicic acid (HFS) for fluoridation purposes and with Sodium Hydroxide; used for the pH adjustment of the finished water.  The finished potable water is then pumped directly to Harrodsburg’s and consecutive water system’s distribution systems for use by the customer at the tap.

Water Quality Monitoring

Continuous laboratory analysis is performed at the Harrodsburg Water Treatment Plant and in the distribution system to ensure that all water treated at our facility exceeds state and federal water quality compliance standards.  Water is tested for turbidity, alkalinity, hardness, fluoride, pH, chlorine disinfectant residual among a multitude of other periodic water quality parameters.

Public Notices

Public Notice: The Harrodsburg Water Department has incurred a TTHM Monitoring Violation.

Our water system failed to comply with a required testing procedure.  Even though this was not an emergency, as our customers, you have a right to know what happened and what we did to correct the situation.

*We are required to monitor your drinking water for specific contaminants on a regular basis.  Results of regular monitoring are an indicator of whether or not our drinking water meets health standards.  During 10/1/2018 – 12/31/2018, we did not complete all monitoring or testing for trihalomethanes (TTHM), and therefore cannot be sure of the quality of your drinking water during that time.*

Any sample we collect must be sent to and analyzed by a certified laboratory within a specified amount of time.  We collected the sample on 11/14/2018 and it was received by our contract lab.  The lab performed the analysis and the test results were good, however, the laboratory did not do the analysis within the allowed holding time.  The test results were rejected by the Division of Water.  Since that sample is required to be collected during a specific week, we were not allowed to collect a replacement sample and therefore received a monitoring violation.

There is nothing you need to do at this time.  You may continue to drink the water.  If a situation arises where the water is no longer safe to drink, you will be notified within 24 hours.

*Please share this information with all the other people who drink this water, especially those who may not received this notice directly (for example, people in apartments, nursing homes, schools, and businesses).  You can do this by posting this notice in public places or distributing copies by hand or mail.
