Superintendent

The Wastewater Treatment Plant located on the Southwest side of Hartford City is a conventional activated sludge plant with advanced tertiary treatment that produces a high quality,environmentally friendly effluent. The treatment plant was original built in 1961 and was ran in coordination with the "Old Plant" that was located in the City. In 1978, the "Old Plant" was taken out of service due to age (original start up date in 1938). This resulted in the current facility's first major upgrade. Additional primary, and secondary clarifiers were added as well as additional aeration basins to handle the increased loading that would now be directed to this facility.  The facility also had Advanced Waste Treatment (AWT) Filter Cells installed to help create our high quality effluent.

In 1998, the facility underwent it's second major renovation by upgrading it's aeration tanks to fine air diffusers, remodeling and relocating our laboratory and administration building as well as upgrading our biosloids handling program to produce a Class A product.

Below are a few important facts and figures concerning the operation and design of the plant:

** 2.2 MGD (million gallons per day) Design Flow

** 2.5 MG Peak Flow

** 1.6 MGD Average Daily Flow

** Approx. 3000 residential costumers with a variety of commercial/industrial users

** High Rate of BOD5, TSS and NH3N removal (typically 95% or higher)

** Competitive User Rates compared with local  communities (Contact Utility Office for more information concerning rates)

** 4 sub-departments staffed by 8 full-time operators that all have a variety of certifications from CDL licensing to Class IV Municipal and Class A industrial wastewater certifications.

Laboratory

As was stated earlier, the laboratory was upgraded and relocated in the new administration building in 1998. The laboratory staff is responsible for sampling and performing the needed analysis required by the facility's NPDES permit. The lab monitors for BOD5, TSS, NH3N, pH and DO five days a week year round. The also monitor and test chlorine residual and E. coli for MPN (most probable number) during disinfection season which runs from April 1st to October 31st.  Most of the facility's operational adjustments are made based on the results derived by the laboratory tests. The lab is equipped and staffed at a level so that they are able to do as much testing and analysis as possible in-house in order to keep user rates in check. The laboratory is also responsible for industrial monitoring in order to ensure that our industrial users are in compliance with the standards set out in our sewer users ordinance.

Maintenance & Operations

This department is responsible for keeping the facility in top working order, as well as completing the day to day tasks and operational changes need based on laboratory results. The members of the maintenance department manage 2 lift stations located in town in order to keep flows coming towards the facility for treatment. They are also responsible for maintaining 4 raw sewage pumps, 3 return sludge pumps, a number a aeration tank blowers, as well as primary and secondary tank maintenance and cleaning. Their work continues by operating the advanced waste treatment filters and chemical feed systems used for disinfection at a high level of efficiency. With an effective preventive maintenance program, skilled staff and access to modern tools and equipment, the maintenance and operations department has found that there are few jobs too big for them to handle. Like the lab, the maintenance crew does most of it's work in-house when possible to maintain a healthy budget and lower rates for the customer.

Biosolids Handling

This department is responsible for the final treatment and disposal of the facility's sludge. The biosolids handling facility typically processes of 2.3 million gallons of 2% sludge annually. Through the use of an Ashbrook Belt Filter Press, the biosolids program dewaters the liquid sludge into a cake yielding up to 25% dry solids (which is a significant reduction in volume which translates into increased savings at the time of disposal. In order to be environmentally conscientious, the the Biosolids Department utilizes Class A Technology developed by RDP Technologies to produce an EQ (exceptional quality) biosolid that meets the 503 requirements set out by EPA and IDEM for beneficial land application of the departments end product. The end product is a high lime soil-like materialthat has beneficial amounts of nutrients, micro nutrients and organic matter that can be used as a supplement to farm ground and gardens. It is the goal of the biosolids department to beneficially land apply as much of the nearly 200 Dry Tons of biosolid (annual production) as possible. The department welcomes visitors for a tour. Feel free to call a schedule a visit or email at hcwwtp@hartfordcity.net.

CSO Department

The City of Hartford City is a CSO Community (combined sewer system). Combined sewers allow for the joint transport of sewage and stormwater in the same pipe to the wastewater facility for treatment. During periods of heavy rain, the combined sewers become surcharged and need a relief point. These permitted relief points, known as CSOs, are strategically located on local waterways. All of the CSO points are marked with orange signs. Unfortunately, when this happens, these CSO points discharge partially treated sewage to these waterways. Please understand that this type of system was accepted and approved technology when it was in stalled nearly 50 years ago. These discharge into local waterways are not a good thing, but they are better then the alternative- backing up into your home or business. The wastewater departments uses best management practices to minimizes the effects of CSO events. Sewers are cleaned to maintain maximum volumes, the treatment plant maximizes incoming flows to capture the "1st Flush" (heavy levels of pollution) and lift stations are kept in top running order by the maintenance department. The City also has policies that new development projects are required to have separated storm and sanitary sewers. There have also been large City-wide sewer separation projects like the Commissioner's Ditch project that have greatly reduced the number and duration of CSO events that occur in Hartford City. Continued separation projects will occur once monies have been secured. In the meantime, the City has submitted a Long Term Control Plan to help deal with our CSO until the time in which they are separated. Should you wish to be notified of CSO occurrence, the CSO department has a system that allows for you to be notified of a CSO event. Contact the wastewater facility to have your name added to our list if you so desire. As a citizen of the community, you can help minimize the chance of CSO events by making sure your eaves troughs and crawl space/basement sump pumps are not connected to City sewers. Every gallon of storm water that can be kept out of the sewer is one gallon of discharge from a CSO point that does not have to be discharged to a stream or river. Thanks for your help on this issue.
