Project Description

The Northport Leelanau Township Utility Authority’s (NLTUA) wastewater treatment plant (WWTP) is a 0.132 million gallon per day (mgd) facility. The wastewater is collected in the system by gravity sewer and low-pressure force mains. Two lift stations help push the water along to the Main Street Lift Station. From the Main Street Lift Station, water is pumped to the WWTP. When the wastewater reaches the treatment facility, gravity flows through the treatment processes starting at the fine screen unit. After the fine screens, the waste stream flows to the primary anoxic basin and moving bed biofilm reactor (MBBR). After the MBBR, the water flows to the settling basin where solids settle and are then pumped to the solids basin. The settling basin effluent then flows through the polishing filters before final dosage into the rapid infiltration beds (RIBs).

2018 Project Overview

Jacobs has the privilege of operating and maintaining the NLTUA WWTP, three lift stations, and collection system including residential grinder pumps since 2008. During that time, we have strived to increase treatment efficiency, decrease vulnerabilities, and reduce the likelihood of emergency calls. We are pleased to present the following operations and maintenance (O&M) year in review.

Plant Performance

The NLTUA WWTP operates under a Groundwater Discharge Permit issued and regulated by the Michigan Department of Environmental Quality (MDEQ). The following is a summary of the facility’s performance in comparison to the requirements of its permit.

Maximum Daily Influent Flow

The facility is permitted to receive a maximum influent daily flow of 132,000 gallons per day (gpd). As depicted in Exhibit 1, the month with the highest maximum daily influent flow was May when influent flow reached 79 percent of the facility’s permitted maximum flow.

Monthly Average Biochemical Oxygen Demand

Biochemical oxygen demand (BOD) is a measure of the amount of oxygen that will be consumed in the receiving waters by the effluent the facility discharges, or the strength of the effluent. The permitted effluent monthly average for the NLTUA WWTP is 30 milligrams per liter (mg/L). Exhibit 2 depicts the actual monthly average effluent BOD concentrations in comparison to the permitted limit. The highest monthly average BOD concentration in the plant effluent was 5 mg/L in 2018.

The daily maximum limit for the NLTUA WWTP effluent BOD concentration is 45 mg/L. Exhibit 3 is a comparison of the daily maximum effluent BOD concentrations versus the permitted maximum daily BOD concentrations. In 2018, the daily maximum BOD concentration in the plant effluent was 7 mg/L.

Effluent pH

The pH of the effluent is an indication of the intensity of its acidity or alkalinity. A low pH indicates acidity, and a high pH indicates alkalinity. Effluent pH is monitored and regulated to ensure minimal impact on the receiving waters and/or soil it is discharged to. The pH of the WWTP effluent ranged from 6.6 – 7.8 in 2018. This range is within the permitted pH range of 6.5-9.0. (Refer to Exhibits 4 and 5.)

Total Phosphorus

Phosphorus is a nutrient that aids in the growth of microorganisms and plant life, however, if present in the effluent discharged from the facility in too high of concentrations, it could lead to algae blooms, plant overgrowth, and decreased dissolved oxygen concentrations in the receiving waters and/or soil. Exhibits 6 and 7 compare the effluent total phosphorus concentrations to the permitted total phosphorus concentrations.

Exhibit 6, compares the effluent monthly average total phosphorus for 2018 to the permitted effluent monthly average total phosphorus limit of 0.3 mg/L. The maximum monthly average total phosphorus for 2018 was 0.2 mg/L, which is well within the permitted limit.

Exhibit 7, compares the daily maximum total phosphorus concentrations to permitted daily maximum total phosphorus concentration. The plant effluent daily maximum total phosphorus for 2018 was 0.4 mg/L which is below the permitted daily maximum limit of 0.5 mg/L.

In addition to the parameters discussed above, we monitor and report dissolved oxygen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total inorganic nitrogen, chloride, and sodium concentrations in the effluent. The permit contains no limits for these parameters.

Monitoring Wells

On a quarterly basis, the permit requires that monitoring wells up gradient and down gradient of the facility’s effluent discharge are sampled and monitored for various parameters. The pH values of the samples taken at the down gradient monitor wells are the only monitoring well parameters with regulated limits. Exhibits 8 and 9 compare the permitted maximum, and minimum pH values, with the actual maximum and minimum pH values from each down gradient monitoring well in 2018.

2018 MDEQ Reporting

In accordance with MDEQ reporting requirements for the NLTUA WWTP, Jacobs completed and submitted the following reports:

We strive to provide the best quality of service we can day in and day out. We understand that the Village has many fiscal demands and are focused on minimizing the financial impact operating and maintaining the WWTP, collection system, and grinder systems has on the Village’s budget.

Base Fee/Direct Cost Overview

The Village pays, to Jacobs, a fraction of our base fee every month. Our base fee is the direct cost incurred in operating and maintaining the WWTP, collection system, and grinder pump systems, plus our margin. Included in the base fee is, 300 repair labor hours, and $8,000 in repair expenses. Direct costs incurred in a contract year over/under the budgeted amount are 50 percent invoiceable/refundable to the Village. Direct cost for 2018, were below the budgeted amount by $17,651.01. Some of this cost savings was a result of not contracting out the bed maintenance, as done in the past, but instead using a more ecological approach of controlling vegetation on the RIBs. Jacobs developed a schedule of bed maintenance which involves rotating the placement of tarps on the beds to kill the vegetation eliminating the use of chemicals for this purpose. Exhibit 10 includes a financial summary for 2018 and compares 2018 to previous years.

Financial Summary

Repair Expenses

Repair hours and expenses over/under what is included in the base fee are 100 percent invoiceable/refundable to the Village. In 2018, repair expenses related to the WWTP, collection system, and grinder pump systems amounted to $29,745.99. Exhibit 11 itemizes repair expenses greater than $200. Exhibit 12 summarizes the total repair expenses incurred. The replacement of one of the Landia mixers in the MBBR amounted to $14,899 and accounts for 50 percent of the total repair expenses this year. These mixers are essential to maintaining adequate treatment of the waste stream entering the MBBR, they function to keep the media suspended allowing the bacteria on the media to fully contact the influent flow and remove pollutants. This ensures that the for mentioned permit limits are met.

Operations and Maintenance

Maintenance Work Orders

Jacobs performed 702 work orders (WOs) in 2018. Ninety-one percent of the WOs were proactive in nature falling under the category of preventive maintenance (PM) activities. Jacobs maintenance program is centered around equipment capacity assurance through proper asset management, a focus that prolongs the life expectancy of the Village’s assets, minimizes the likelihood of compliance issues related to asset failures, reduces safety vulnerabilities, optimizes staff labor hours, and curtails the cost of repairs with the use of proper planning and scheduling. Our proactively robust maintenance program is geared toward decreasing the need for emergency and corrective maintenance (CM) repairs, which accounted for only 9 percent of our maintenance WOs in 2018. Exhibit 14 highlights our maintenance WO activity through the last year.

Annual ARV Inspections/Repairs

Trapped air in a collection system can slow or completely block flow, cause water hammer, and accelerate pipe corrosion. To prevent this, air release valves (ARVs) are installed at the high points of pressurized collection systems. ARVs designed to automatically release pockets of accumulated air from a pipeline while the system operates under pressure.

As part of this year’s ARV inspections, Jacobs replaced two ARVs in the collection system. One of the ARVs is located on M22 and the other at the Golf Course. During the inspections, we found the ARV located on North Shore Drive to be corroded inside and out. Jacobs recommends a complete replacement of the ARV along with all associated hardware. All the other ARVs on the collection system were in good working condition. All valves where exercised and the units disassembled, cleaned, inspected, and placed back into service.

Waukazoo Inspections – June 2018

As part of our regularly scheduled PM program, we inspect the Waukazoo sewer line. In June 2018, when this inspection was last performed, the sewer line was relatively clear, with just a slight buildup of grease on the edge of the manhole in front of Tucker’s.

Treatment Plant

Headworks and Controls

The facility’s programmable logic controller (PLC) and supervisory control and data acquisition (SCADA) computer was replaced after experiencing damage caused by a lightning strike. In addition, we added an uninterrupted power supply (UPS) to the system to prevent communication and program losses resulting from power outages.

Fine Screen

When the wastewater enters the facility, it first goes through a vertical fine screen that automatically removes rags and debris from the waste stream to protect downstream equipment, particularly the MBBR media from clogging. The water level in the screen inlet chamber is continuously monitored by a level transducer. The level transducer initiates the control system to operate the spiral screw when the water level reaches a certain height. This level transducers failed in 2018 and were replaced.

In the picture of the fine screen, you will notice that it is covered by an insulated tarp. Under the insulated tarp we also installed heat tape. Together the insulated tarp and heat tape prevent freezing of the rags that travel up the screw and drop into a trash receptacle. If the rags freeze, they bind the screw and prevent it from operating. Covering the screen is part of our annual fall winterization of the facility.

Anoxic Basin

As described above, the plant influent is screened when it enters the facility. After screening, the wastewater is routed to the Primary Anoxic Zone, where it blends with the MBBR effluent recycle stream. The dissolved oxygen in the Anoxic Zone is generally kept below 2.0 mg/L to assist with the denitrification (process of converting nitrites/nitrates to nitrogen gas). The incoming wastewater provides the carbon source necessary for denitrification. The Primary Anoxic Zone also provides equalization for the influent organic loading to the MBBRs. This year, Jacobs, with assistance from Chis Holton, KAL Excavating and Northern A-1, cleaned the Anoxic Zone for the first time since the facility was brought online. Jacobs performed as much of the work as we could safely perform to reduce costs. We assisted with removing the basin covers, removed much of the media from the basin, cleaned the screens, and assisted with cleaning the basin. With the basin empty, we discovered a leak in the liner, and two holes in the liner above the water line all of which were repaired by Northern Seal. While onsite, Northern A-1 cleaned the grit and debris out of the influent control structure. We recommend the Anoxic Basin cleaning be performed every 5 years going forward.

MBBR

Influent and recycle flow are routed through the MBBR on a continuous basis. The reactor tanks in the MBBR contain plastic carrier elements (freely moving wagon wheel shaped media) that create a protected home for the attached growth micro-organisms that accomplish the biological treatment (BOD removal, nitrification, denitrification). The aeration and mixing systems allow the reactor contents to be mixed (mechanically and/or with air), providing intimate contact between the carriers and the wastewater. The submersible mixers are installed in four of the six MBBR cells to provide mixing where air is shut off (i.e., anoxic zones) or where air flow alone is not enough for mixing. Media screens are provided to retain the MBBR carriers in each MBBR cell.

The aeration blowers provide the MBBR with the oxygen and mixing necessary to achieve complete treatment. Blower 1’s motor fan was refurbished in 2018 when the blower repeatedly overheated. Maintaining two operable blowers ensures we will be able to meet the oxygen and mixing demands of the reactor cells in the MBBR reducing the vulnerability of not adequately treating the wastewater.

Cell 6 Screen Cleaning

We were called to the facility several times this fall for plant backups between cell 6 and the settling basin. After several attempts to address the issue by air blasting the screens and then draining cell 6 making an entry and power washing the screens, we found the root cause to be the amount of media in this zone. We transferred a portion of the media to cell 1 of the MBBR and have not had a reoccurrence of the plant backups at this location since screens retain the MBBR carriers in each MBBR cell.

Cell 6 Mixer Replacement

We replaced Landia mixer 7 in cell 6 of the MBBR. As mentioned previously, the Landia mixers are essential to providing complete treatment of the incoming flow by providing proper mixing which keeps the media suspended and in contact with the waste. They are designed to provide mixing without damaging the plastic media.

Cavitation Air Flotation Tank (CAF) Gate Replacement

We replaced the gate valve used to isolate the cavitation air flotation tank from the MBBR.

Settling Basin Cleaning

The effluent from the MBBR flows through the CAF tank to the settling basin which provides a space for solids to settle out before entering the polishing filter system and other downstream processes. Jacobs cleans the solids and debris out of the settling basin on an annual basis. This year, while we had the basin down and flow to the plant diverted to the out-of-service reactor basin, we took the opportunity to perform a thorough cleaning of the effluent structure, reject chamber, and RIB selector structure. We also acid washed the sand filter air lift screens and flushed the sand media.

Safety is a priority for Jacobs. We perform monthly safety inspections at the facility, hold safety meetings daily, and safety training is ongoing for our staff. As of January 2019, Jacobs accumulated over 1,000 days without a loss-time injury, or an injury requiring treatment beyond first aid.

To improve safety at the facility this year, we added railings between the MBBR and the nearby manholes.

Exhibit 15

Polishing Filter Process

Safety

Sand Filters

There are two sand filters at the facility, the purpose of which is to further reduce the concentration of total suspended solids (TSS) and total phosphorus in the treated water before discharge to the RIBs. When a certain water level is reached in the filter, solenoids are triggered to open allowing compressed air into the filter to push the sand up the airlift. The airlift is used to carry the sand up to the wash well for cleaning. The wash (reject) water flows to a reject chamber and is then pumped to the biosolids storage basin with the use of reject pumps. Exhibit 15 highlights this process.

History has shown that the sand filters periodically backup causing personnel to be called out increasing the callout hours charged to the Village. Three of the most common causes of these backups are binding/blinding of the sand in the filters, buildup of solids in the rejects chamber, and plugs in the reject chamber discharge line. To reduce plant backups and callouts, we perform regularly scheduled PM which includes air blasting the sand in the filters, cleaning the reject chamber, and air blasting the reject line. As stated above, compressed air is needed to push the sand up the sand filter airlift for washing. In 2018, we replaced one of the air compressors that supply this compressed air.


Project Staff

The NLTUA WWTP Project Manager is Elizabeth Hart. She is supported by a staff of 15 technical and non-technical employees. On call personnel for the NLTUA include: Nathan Callison, Kerry Gensler, Shane Wyatt, and Joe Brown.
