Water Filtration

The City of Muskegon’s Water Filtration Plant is a drinking water treatment facility located on the Lake Michigan shoreline near Pere Marquette Park. The Water Filtration Plant provides drinking water to a population of nearly 90,000 in the City of Muskegon and several neighboring communities, including: Dalton Township, Fruitland Township, Fruitport Township, Laketon Township, Muskegon Township, the City of North Muskegon, the City of Norton Shores, and the City of Roosevelt Park.

The Water Filtration Plant produces over four billion gallons of drinking water annually. The term “drinking water” is widely used to describe water that is safe for consumption, but it has a variety of uses beyond drinking. Residential uses include drinking, cooking, washing, laundering, and irrigation. Similar uses are seen in commercial buildings such as stores, offices, hotels, restaurants, schools, and more. The Water Filtration Plant also plays a crucial role in fire protection by providing water to fire hydrants.

A team of eleven state-certified Waterworks System Operators manages the drinking water treatment and distribution processes 24 hours a day. Operators continuously monitor water quality at each stage of the treatment process and make adjustments to ensure proper treatment. Our team of operators is also responsible for the maintenance of the Water Filtration Plant equipment and facilities. Our communities have access to a supply of safe, clean, abundant, and aesthetically pleasing drinking water due to the work our staff performs every day.

The City of Muskegon’s water system dates back to 1874 with the construction of a pump station and reservoir at Eighth St. and Houston St. Fire protection was the impetus for the city’s first water system. Eventually the reservoir at this location was unable to provide the volume of water required by the city, and a new pump station was constructed in 1891 on the Lake Michigan shoreline. Two major changes were implemented in the 1920s: the steam-driven pumps were upgraded to electricity and chlorination was started in response to the typhoid fever epidemic. During the 1930s, sedimentation basins, six filters, and a 2.8-million-gallon drinking water reservoir were constructed, permitting complete water treatment to begin. Major upgrades occurred throughout the 1960s, 1970s, 1990s, 2000s, and 2010s. These upgrades increased capacity, upgraded the treatment process, and improved reliability. While the plant is well maintained and modern, some of the infrastructure constructed in the 1920s is still used in the treatment process today, nearly 100 years later.

Our water source is Lake Michigan. The Great Lakes provide some of the best quality water when compared to other surface water sources, such as rivers and inland lakes. However, because Lake Michigan is surface water, it still will contain sediment, disease-causing organisms, and also at times, compounds that cause tastes and odors. To make the water potable, sediment must be removed from the water and harmful microorganisms must be destroyed. Treatment of the water will provide multiple barriers against disease-causing organisms and produce safe, aesthetically pleasing drinking water.

Water from Lake Michigan enters the Water Filtration Plant through a five-foot diameter intake pipeline that travels over one mile into Lake Michigan, terminating at a depth of over 30 feet. The length and depth of our intake permits it to supply more consistent and higher quality water than is available directly on the shore. However, the biological, chemical, and physical properties of the water will still be impacted by storms, wind, currents, temperature, rainfall, river flow, runoff, ice formation, and water levels. This is not a problem, as the drinking water treatment process is designed to handle water of varying quality.

Protecting our drinking water source is critical. Treatment can become more difficult and expensive due to emerging concerns that impact water quality. Examples include the introduction and flourishing of invasive mussels, the increasing frequency of algal blooms, and the presence of per- and polyfluoroalkyl substances. The Lake Michigan watershed encompasses 45,600 square miles of land where all streams and rainfall drain into Lake Michigan. All activity within this area has the potential to affect our drinking water, and any substances dumped on the ground have the potential to enter ground water or surface water that eventually flows to Lake Michigan. The City of Muskegon has a Source Water Intake Protection Plan (SWIPP), a voluntary endeavor undertaken to ensure the long-term viability of our drinking water source. This plan was implemented in 2017 and updated in 2023.

The Water Filtration Plant has a treatment capacity of 40 million gallons per day (mgd). This equates to 27,778 gallons per minute, or enough water to fill eight average-sized bathtubs every second. The Water Filtration Plant treats enough water to meet the demands of our customers, which fluctuates on a daily, sometimes hourly, basis. Treatment rates vary seasonally and range from 6 mgd to 23 mgd.

The Water Filtration Plant uses conventional water treatment, a method widely used around the world for producing drinking water. This five-step process includes disinfection, coagulation, flocculation, sedimentation, and filtration.

Water treatment at the Water Filtration Plant begins with disinfection using a process called chlorination. Chlorination involves adding chlorine to the drinking water to kill disease-causing organisms such as parasites, bacteria, and viruses. This process has been identified as one of the ten greatest public health achievements of the 20th century for its ability to control infectious diseases. Staff at the Water Filtration Plant manage the chlorination process to maintain a detectable level of chlorine throughout the water system. The presence of a detectable level of chlorine in drinking water indicates that a sufficient amount of chlorine was added initially to the water to inactivate the organisms that cause disease. It also is critical in protecting the water from recontamination during its movement through the water distribution system.

The next three steps of conventional water treatment—coagulation, flocculation, and sedimentation—remove solids from the water before it is filtered, allowing more effective and efficient operation of the filters. These stages of treatment occur mostly within two, 1.2 million-gallon basins. Overall, these treatment processes can remove up to 90% of the solids from the lake water. First, a coagulant is added through a mixer that rapidly disperses it throughout the water causing the small, microscopic solid particles to begin combining into larger, heavier particles called floc. The water then flows through a series of four flocculation basins where it is gently stirred by large paddles to facilitate continued particle growth. Each successive stage of stirring is slower to allow the floc to grow without breaking apart. The water then flows into a sedimentation basin where the floc falls to the bottom, a process known as sedimentation or settling. Our settling basins use inclined plate settlers that are made of 3,456 metal plates that are spaced a few inches apart and inclined at 55 degrees. The plate settlers allow for more efficient and quicker settling of the solid particles, in part due to their total surface area of 216,000 ft2. Once the solid particles have settled at the bottom of the basin, the cleaner water from the top of the basins goes to the filters.

The final stage of conventional water treatment is filtration. Filtration removes some of the solids that were not settled out earlier in the treatment process. The Water Filtration Plant has ten filters that are approximately 920 ft2 each. Each filter consists of 12 inches of sand topped with 18 inches of anthracite coal. The high surface area of the anthracite coal and sand make them excellent at adsorption. Some of the remaining solids are removed from the water as it travels through the filter and the solid particles stick to the anthracite coal and sand. Once through the filters, the water has completed the treatment process and is considered drinking water. The water flows from the filters into a 5.6-million-gallon reservoir and is ready to be pumped into the communities where it will be consumed.

At the Water Filtration Plant, water flows continuously from Lake Michigan through the treatment process and into the distribution system. This means that when the Water Filtration Plant treats water at a high rate, water flows through the treatment process faster. Depending on the treatment rate, water will spend approximately 8-30 hours to flow from the lake to the point where it is being pumped into the distribution system. Whether treating at maximum capacity or well below, the Water Filtration Plant is designed to produce water that meets all drinking water regulations under any treatment flow rate.

The Water Filtration Plant has 10 pumps with motors of 300-600 horsepower used to distribute water into the community and provide water pressure. In the summer, when water demand peaks, these pumps will be operating at over 20,000 gallons per minute to meet the demands of our consumers. In addition, the City of Muskegon and its customer communities have water distribution infrastructure located throughout the water systems, ensuring abundant water with adequate pressure. Altogether, these water systems include eight water towers totaling 6 million gallons of storage, two water reservoirs totaling 6 million gallons of storage, and five pump stations providing an additional 13 pumps.

Water towers provide both water storage and water pressure. Every 1 foot of water height provides 0.43 pounds per square inch (psi) of pressure. The water towers in the City of Muskegon are over 125 feet high, meaning they alone can provide around 54 psi of pressure without any pumps.

https://www.cdc.gov/fluoridation/basics/timeline.html

Fluoride has been shown to be important in keeping teeth strong and reducing cavities and has been identified as one of the ten great public health achievements of the 20th century. The City of Muskegon fluoridates its water supply by adding a small amount of fluoride to the water to supplement the fluoride that occurs naturally in Lake Michigan water. The final level of fluoride in the water is around 0.7 part per million (ppm), which is the recommended level by the U.S. Public Health Service. Muskegon played an important role in the early studies of fluoridation of municipal drinking water. Grand Rapids began fluoridating its drinking water in 1945, while Muskegon did not, functioning as the experimental control. With the studies showing the effectiveness of supplementing fluoride levels in municipal drinking water, Muskegon began fluoridating its drinking water in 1951.

The temperature of Lake Michigan water changes seasonally. At the Water Filtration Plant, lake water temperatures have ranged from 35-76 °F over the last five years. These temperature changes can be noticeable in the water delivered to consumers, but more critically, temperature changes usually indicate changes in the biology and chemistry of the water. These changes can alter the attributes of the water that flows through the treatment process and the distribution system. One noticeable change can be in the taste and smell of the water during periods of warm water in Lake Michigan. Powdered activated carbon (PAC) is added to the water to remove taste and odor causing compounds. Rapid changes in Lake Michigan water quality can allow the smell of chlorine to become more prevalent, or it might permit an earthy smell to develop. When this occurs, the drinking water at your tap remains safe to drink and touch.

Filter Backwashing

The portion of the filter that separates the unwanted solid particles from the water is referred to as filter media. The filter media at the Water Filtration Plant are anthracite coal and sand, with each one being composed of many individual grains. As water flows through a filter, voids between these grains of media will fill with the filtered solid particles, and as these voids fill, filters experience a reduction in flow and operate less efficiently. The grains of media also become coated with filtered solids. The higher the amount of filtered solids that exists in the voids and coated on the media, the more likely it becomes that the solids will pass through the filter and enter the drinking water. Allowing filtered material to pass through the filter must be avoided at all costs.

Backwashing is a process of cleaning filter media to remove the filtered material from the void spaces and surface of the media and return the filter to its original condition. The process is referred to as backwashing because it uses low pressure air and drinking water that is pushed up from the bottom of the filter, a reversal of how a filter normally operates. A filter can operate for 4-12 days before it requires backwashing. Annually, the Water Filtration Plant uses nearly 38 million gallons of water to backwash filters, using roughly 100,000 gallons of drinking water to clean a single filter. While this might seem like a lot of water, it only accounts for about 1% of treated water.

Historically, the nearly 100,000 gallons of filter backwash water, with the high number of solid particles it contained, was drained directly back into Lake Michigan each time a filter was backwashed. In 2004, the Water Filtration Plant received significant upgrades, including the construction of a sophisticated water recycling system. This system separates the solids from the water, and then reintroduces the water at the beginning of the treatment process. Today, water is no longer drained back into Lake Michigan.

Sludge

Sludge is a waste product of the water treatment process. The sludge produced at the Water Filtration Plant is created from the solids removed from the water and the water treatment chemicals. Initially, sludge is more than 98% water. The Water Filtration Plant has two clarifying basins used to thicken the sludge by separating the solids from the water. Once the sludge is thickened, it is pumped outside to drying beds. In the drying beds, even more water is removed from the sludge through a combination of evaporation and mechanical dewatering. There are two primary sources of mechanical dewatering. The first comes from a front end loader moving the sludge and spreading it into thin layers. The second is the freeze-thaw cycle. Once most of the water has been removed, the sludge resembles dirt and is disposed of in a landfill. On average, the Water Filtration Plant produces 800 tons of sludge annually.

The Water Filtration Plant laboratory is state-certified, allowing us to perform certain sample analysis that are required by drinking water regulations. The recertification process occurs every three years. Being certified requires us to pass annual proficiency tests, where we analyze and submit results for tests samples that are unknown to us. Being certified requires us to have a documented and active Quality Assurance (QA) plan and regularly perform Quality Control (QC) checks to ensure the accuracy of our data. These steps assure the orderly application of practices to remove or reduce errors in the laboratory caused by personnel, equipment, supplies, and methodology.

In total, our operators perform over 100,000 tests annually.

Two of the most closely-monitored water quality parameters are chlorine and turbidity levels. Chlorine levels provide insight into the effectiveness of our disinfection process and are an important indicator on the potability of water. In addition to measurements made by the water plant operators, an instrument monitors chlorine levels at the water plant continuously. Turbidity is cloudiness in the water that results from individual solid particles in the water, and it is a key test in water quality as it indicates the effectiveness of the solids removal process. Water Plant Operators measure turbidity multiple times daily. In addition to the measurements made by the water plant operators, 15 turbidity meters are constantly measuring and recording the turbidity of the drinking water. All drinking water has its turbidity measured twice before it flows into the drinking water reservoir—once immediately after filtration and once right before entering the reservoir.

In addition to chlorine and turbidity, Water Filtration Plant staff also regularly monitor water temperature, pH, alkalinity, hardness, fluoride, color, organic matter (UV 254), taste and odor, Total coliforms, E. coli, and heterotrophic bacteria (HPC). Small changes in any parameter can have a profound impact on water treatment!

The infrastructure consists of watermains, pump stations, water towers, reservoirs, and more. Regular sampling throughout the communities we serve is one way of ensuring the water remains safe once it leaves the Water Filtration Plant. Any abnormalities will be used to spur further investigation. Monitoring the water in the distribution systems includes measuring chlorine levels and performing bacteriological (Total coliform, E. coli) testing at sample sites located throughout the distribution system. We perform over 70 tests weekly on water collected from 30 locations in the distribution systems of the cities and townships where we provide water. Water Plant Operators also monitor the distribution system using a high-speed radio network to monitor data from instruments and sensors showing water levels, flows, and pressures. This radio network also permits the controlling of pump stations, elevated water towers, and reservoirs.

The City of Muskegon has participated in sampling under the Unregulated Contaminant Monitoring Rule (UCMR), which provides data to the EPA to evaluate implementing new water regulations and maximum contaminant levels (MCLs). We have also participated in the State of Michigan’s voluntary sampling for algal toxins, which have provided a better understanding of how algae is impacting our source water and
our drinking water.

Our annual water quality report (also referred to as a Consumer Confidence Report), is published annually before July 1. It will report what substances have been detected in the drinking water, but it does not list all of the parameters for which we test. Below is a sample of the many compounds for which the drinking water is regularly tested.

One of the largest expenses encountered in water treatment is electricity, the majority of which is used by the large pumps used to pump water into the communities we serve. The electrical rate paid by the Water Filtration Plant varies based on the time of day. Staff at the Water Filtration Plant fill all water storage tanks and reservoirs when electrical rates are cheapest, allowing us to minimize pumping during the hours with the highest electrical rates. The Water Filtration Plant uses nearly 5 million kWh per year, while an average home is estimated to only use 11,000 kwH per year. Because the Water Filtration Plant needs to run continuously, two large generators are able to power the plant during power outages to ensure an uninterrupted supply of water.
