E. Coli in Cisterns: Risks, Testing, and Prevention

Cisterns are a reliable source of water for many households, cottages, farms, and off-grid properties. They provide essential storage, especially in areas without municipal water connections. But with any private water supply comes responsibility. One of the biggest risks cistern owners face is contamination, especially from E. coli.

E. coli in cisterns is more common than many people realize, and it can pose serious health risks if not addressed. This article explores how ecoli gets into cisterns, what it means for your health, how to test for it, and the best ways to prevent and manage contamination.

What is E. Coli?

E. coli, short for Escherichia coli, is a type of bacteria commonly found in the intestines of humans and animals. While many strains are harmless, some can cause illness when consumed in drinking water.

The presence of E. coli in a cistern is a red flag. It signals that the water has been contaminated with fecal matter, which may also contain other dangerous pathogens, viruses, or parasites. In other words, if your cistern tests positive for E. coli, it’s not just bacteria you need to worry about; it’s a broad indicator of unsafe water.

How Does E. Coli Get Into a Cistern?

Cistern contamination can happen in several ways:

1. Surface Runoff and Rainwater

If your cistern collects rainwater, contamination can occur when bird droppings or animal waste wash off the roof and into the tank. Even a small amount of droppings can introduce harmful bacteria.

2. Unsealed or Damaged Lids

A cracked or poorly sealed cistern lid invites trouble. Animals, insects, or debris can enter and introduce bacteria.

3. Water Delivery Trucks

If you rely on water deliveries, the truck hoses, tanks, or handling methods may not always be sanitary. One contaminated delivery is enough to seed your cistern with E. coli.

4. Nearby Septic Systems

Leaking or improperly maintained septic tanks can leach bacteria into the ground, eventually making their way into underground cisterns or water storage areas.

5. Poor Maintenance

Over time, sludge and biofilm can build up inside a cistern. This creates a perfect environment for bacteria to grow, especially if the tank is never cleaned or disinfected.

Health Risks of E. Coli in Cisterns

The health risks depend on the strain and the amount of exposure, but drinking or cooking with water contaminated by E. coli can lead to:

Mild to severe diarrhea

Stomach cramps

Nausea and vomiting

Fever

In severe cases, particularly with the strain E. coli O157:H7, infection can cause kidney damage and even be life-threatening—especially for young children, the elderly, or people with weakened immune systems.

Even if you don’t drink directly from your cistern, contaminated water can still be dangerous if used for brushing teeth, washing food, or accidentally swallowed during bathing.

How to Test for E. Coli in Your Cistern

The only reliable way to know if your cistern contains E. coli is to test it. Here’s how:

1. Collect a Water Sample
Use a sterilized bottle from a local health unit or certified lab. Take the sample from a tap that’s fed directly from the cistern, not from a filtered or treated line.

2. Submit to a Lab
Most health departments or private labs can test water samples for E. coli and total coliform bacteria. Results usually take 24–48 hours.

3. Interpret the Results

    – No E. coli detected: Your water is currently safe from fecal contamination.

    – E. coli detected: Immediate action is required. Do not drink the water until it is disinfected and retested.

    – Total coliforms detected: While not as dangerous as E. coli, this indicates possible contamination pathways.

    Routine testing is key. Many experts recommend testing cistern water at least 3–4 times per year, especially after maintenance, refilling, or heavy rains.

    How to Remove E. Coli from a Cistern

    If a test comes back positive for E. coli, don’t panic; it can be dealt with. Here are the common steps:

    1. Disinfection with Chlorine

    The most common solution is to shock-chlorinate the cistern:

    – Drain the tank if possible.

    – Scrub and rinse the interior to remove sludge and debris.

    – Refill with clean water.

    – Add a chlorine solution (household bleach without additives works in emergencies) and circulate through the system.

    – Allow the water to sit for several hours before flushing.

    2. UV Filtration Systems

    Installing a UV (ultraviolet) water purifier at the point of entry is a great long-term defense. UV systems kill bacteria like E. coli instantly without altering the taste of the water.

    3. Ongoing Chlorination or Ozone

    For households at high risk, a continuous disinfection system using chlorine or ozone can keep water safe.

    4. Professional Cleaning

    If your cistern has years of buildup, hiring a professional cleaning service ensures a thorough job. Or DIY cistern clean!

    Preventing E. Coli in Cisterns

    Prevention is always better than dealing with contamination after the fact. Here are best practices:

    – Keep lids tightly sealed to prevent animal entry.

    – Clean and disinfect your cistern annually.

    – Inspect delivery hoses and request clean handling from water delivery companies.

    – Install a first-flush diverter if using rainwater collection to redirect the initial dirty water off the roof.

    – Test your water regularly to catch problems early.

    – Add a point-of-use filter (such as reverse osmosis) for drinking water taps.

    Common Questions About E. Coli in Cisterns

    Can boiling water kill E. coli?
    Yes. Boiling water for at least one minute kills E. coli and most other pathogens. This is a safe short-term solution until the cistern is disinfected.

    Can I use bleach in my cistern all the time?
    Small amounts of chlorine can help keep water safe, but too much can affect taste and smell. Regular testing is needed to keep levels balanced.

    If my cistern tests positive once, will it always be contaminated?
    Not necessarily. A one-time incident may be solved with cleaning and disinfection, but ongoing contamination suggests a larger problem with your system or environment.

    Final Thoughts

    E. coli in cisterns is not something to ignore. It signals a serious breach in water safety that can affect your health and the health of your family. The good news is that with regular testing, good maintenance practices, and effective disinfection strategies, you can keep your cistern water safe and reliable.

    A cistern should be a dependable water source, not a hidden health hazard. By staying proactive, you can enjoy clean, safe water all year round.

    Rising Bulk Water Prices: How to Save Money with Smart Monitoring

    PTLevel Tank History

    Rising Bulk Water Prices: How to Save Money with Smart Monitoring

    The Rising Cost of Bulk Water

    Across North America, homeowners, farms, and businesses are noticing higher bulk water prices. Municipalities are adjusting rates upward to cover increased operating costs, while private haulers charge premiums during high-demand periods. For anyone relying on cisterns or bulk water deliveries, these price changes can add up quickly.

    How Heat Waves Drive Up Water Demand

    During prolonged hot spells, two things happen at once:

    Water Supply Drops

    Rivers, reservoirs, and wells run lower during drought and heat events.

    Water Demand Spikes

    Families, farms, and businesses use more water for cooling, livestock, irrigation, and daily needs.

    This combination creates pressure on systems and increases heat wave water demand. The result? Scarcity pricing, emergency hauling fees, and even water shortages in some communities.

    Why Water Hauling Costs More in Summer

    When demand outpaces supply:
    – bulk water haulers raise rates to cover extra trips and longer hauls
    – municipalities increase wholesale fees to manage treatment and delivery costs
    – emergency fills cost more than planned deliveries (sometimes double!)

    If you rely on a cistern, the risk isn’t just running dry… it’s paying inflated costs for last-minute emergency water deliveries.

    Saving Money on Bulk Water Deliveries with Smart Planning

    The good news: water customers can fight back against rising costs. The key is knowing exactly when your cistern or tank needs a refill. Instead of guessing or waiting until you run out, smart monitoring gives you control.

    The PTLevel liquid level monitoring system is designed to help you:

    – track water levels in real time (the Wired WiFi PTLevel reports in about once every 2 minutes, the Long Range Wireless PTLevel can report in as frequently as every 4 minutes)

    – check your cistern level from your phone, computer or tablet

    – order water only when you need it. Historical usage data and graphs help schedule deliveries at the most cost-effective times.

    share your water level with your delivery driver. Let your local delivery company see your water level, set them up to receive low level alerts, so they can plan efficient routes and keep your emergency deliveries fee costs down.

    By eliminating guesswork, the PTLevel helps families, farms, and property managers start saving money on bulk water deliveries and keep cisterns topped up at the right time.

    Saving Money on Cisterns with Long-Term Monitoring

    Beyond delivery savings, cistern level monitoring with the PTLevel helps protect your cistern investment:
    – identify leaks or unusual consumption early with alerts
    track seasonal trends to manage water budgets
    prevent costly water shortages at rental properties and airbnb’s, cottages, and farms

    Installing a PTLevel is a simple way to make your cistern more efficient and ensure you’re saving money on cisterns year after year.

    Final Thoughts: Peace of Mind During Heat Waves and Year-Round

    Water is becoming more expensive, and climate-driven heat wave water demand will keep pushing costs higher. For homeowners, farms, and property managers, waiting until you’re out of water is becoming unaffordable.

    With PTLevel, you gain peace of mind and practical savings. By monitoring your cistern in real time, you avoid emergencies, reduce costs, and keep your water supply secure… no matter how hot the summer gets.

    Common Signs Your Septic Tank Needs Attention

    Holding Tank Septic Tank Monitor Alarm

    Common Signs Your Septic Tank Needs Maintenance

    First, what is a Septic Tank, and how do you know when it needs maintenance?

    When you’re septic tank needs attention, you need to act fast with maintenance or repair to prevent costly, and stinky, problems. A septic tank is an underground, watertight container designed to treat and manage wastewater from homes or buildings that are not connected to a municipal sewer system. It serves as a critical component of a septic system, which safely processes and disposes of wastewater on-site.

    septic bed, also known as a leach fielddrain field, or absorption field, is a critical part of a septic system that works in conjunction with the septic tank. It is an area of soil or gravel where the treated wastewater (effluent) from the septic tank is dispersed and naturally filtered before being absorbed into the ground.

    Signs your Septic System Needs Maintenance

    Keep reading to the end of the article to find out what to do about each of these problems.

    Slow drains in home

    Gurgling sounds from pipes

    Foul odors around tanks or drains

    Holding Tank Septic Tank Monitor Alarm

    Standing water or soggy soil

    Unusual grass growth

    Frequent toilet backups

    How does a Septic Tank Work?

    Wastewater Flow

    Wastewater from toilets, sinks, showers, and appliances flows into the septic tank. This includes both solid and liquid waste.

    Separation of Solids and Liquids

    Inside the tank, the waste separates into three layers:

    Scum: Lighter materials (like oils and grease) float to the top.

    Effluent: The liquid middle layer, which contains water and dissolved waste.

    Sludge: Heavier solids sink to the bottom.

    Natural Bacterial Breakdown

    Bacteria in the tank break down organic material, reducing the volume of solids over time.

    Effluent Discharge

    The liquid effluent flows out of the tank into a drain field (or leach field), where it is naturally filtered and absorbed into the soil.

    Solid Waste Accumulation

    Over time, sludge and scum build up and must be pumped out regularly to maintain the system’s functionality.

    You can monitor your septic tank levels and your holding tank levels, and get alarms to let you know if there’s a problem, before it’s a big problem?

    • low level alerts
    • high level alerts
    • history graphs
    • temperature tracking

    How does a Septic Bed work?

    Effluent Flow

    After the septic tank separates solids from liquids, the liquid effluent flows into the septic bed through a network of perforated pipes.

    Distribution of Wastewater

    The pipes in the bed evenly distribute the effluent into a gravel-filled trench or a system of chambers.

    Natural Filtration

    As the effluent seeps into the surrounding soil, it is filtered by natural processes. Microorganisms in the soil break down any remaining organic material, pathogens, and nutrients.

    Groundwater Protection

    Once filtered, the clean water continues to percolate through the soil layers, eventually recharging the groundwater without harmful contaminants.

    So now that you understand how the septic system works, let’s dig into common signs you’ll see when your septic tank needs attention, and how a monitoring system can help!

    Lush, patchy, soggy grass around your septic bed is…. bad!

    Because there is extra nitrogen and phosphorus that is naturally found in human and animal waste, when you start seeing lush, patchy, or soggy areas around your septic bed it could mean your septic system is failing.

    Leach lines are commonly made of PVC pipe, and they’re placed into trenches filled with gravel and sand, which help treat the wastewater. The PVC pipes are drilled with small holes so the wastewater can drain out of the pipes and into the surrounding material.

    Lush, patchy, and soggy grass around your septic bed may be signs your septic systems has problems.

    Scenario:

    Tank starts full (100%) and is refilled when it reaches either 30% or 10%.

    Waiting to refill at 10% extends the refill cycle by 1.5 weeks.

    Assumptions:

    30% Refill Cycle: Takes 4 weeks to go from 100% to 30%.

    10% Refill Cycle: Takes 5.5 weeks to go from 100% to 10%.

    Each delivery costs $300.

    Calculation:

    Deliveries per year = 52 weeks ÷ refill cycle duration (weeks).

    Total cost = deliveries per year × $300.

    Annual savings = cost difference between the two scenarios.

    How to save money on your water bill with a cistern

    Explanation

    If you refill at 30%, you’ll need 13 deliveries per year, costing $3,900.

    If you wait to refill at 10%, you’ll only need 9 deliveries per year, costing $2,836.

    This results in $1,064 in annual savings.

    Common Styles and Sizes of Cement Cisterns in North America

    The most common cement cisterns in North America are rectangular or cylindrical tanks buried underground. Sizes typically range from 5,000 liters (1,320 gallons) to 30,000 liters (7,925 gallons). The size you choose depends on your water needs, local rainfall, and available space.

    5,000–10,000 liters (1,320–2,640 gallons): Suitable for small households or supplemental rainwater storage.
    15,000 liters (3,960 gallons): Ideal for families of 4 as a minimum capacity.
    22,500–30,000 liters (5,940–7,925 gallons): Provides a reliable water supply for larger households or farms.

    How to Choose the Right Cistern Size

    When selecting a cistern, consider:

    Your Water Needs: How much water does your household or operation use daily? A typical family of four requires at least 15,000 liters (3900 gallons) per month, with larger tanks offering greater reliability.

    Usage Purpose: Are you storing rainwater, using it for irrigation, or providing potable water?

    Rainfall and Collection Area: For rainwater harvesting, match the cistern size to your roof area and local precipitation rates.

    A tank that’s too small won’t meet your needs, while one that’s too large might waste money and space. Use a cistern volume calculator to fine-tune your choice.

    Hard Water in Cisterns and Your Home

    Shower head

    Water is crucial for daily activities like drinking, cooking, cleaning, and bathing. But when your water contains high levels of minerals such as calcium and magnesium, you may be dealing with hard water. This can affect not just your home’s plumbing and appliances but also your overall water quality. Below, we explore the signs of hard water in cisterns and homes and offer solutions to help you manage its impact.

    Is Your Home Affected by Hard Water?

    Detecting hard water in your home or cistern is essential to avoid potential complications.
    You can test for hard water with a product like this.
    Here’s what to look for:

    Persistent Soap Scum and Residue

    Hard water spots on glasses

    One of the first indications of hard water is soap scum buildup on shower doors, sinks, and utensils. The minerals in hard water prevent soap from lathering properly, leaving a sticky residue that’s tough to clean. This not only leads to more frequent scrubbing but also necessitates stronger cleaning agents, adding to maintenance time and cost.

    Hard water spots on glass

    Solution: Install a whole-house water softening system to reduce mineral content and improve soap performance. For immediate relief, adding a ½ cup of white vinegar to your dishwasher cycle can help cut through the residue and leave dishes sparkling clean.

    We recommend contacting your local water supply business for a whole-house water softener system. But if you’re looking for a DIY option, or want to start small, you could always try just a water-softener shower head or a little bit bigger of a system to handle softening your laundry and shower.

    Stiff, Faded Laundry

    Dull laundry

    Do your clothes come out of the wash feeling stiff or looking dull? The minerals in hard water in your home nteract with detergents, making them less effective and causing detergent residue to cling to fabrics. Over time, this leads to faded colors, rougher textures, and more stubborn stains that resist removal.

    What colour did these towels even used to be?

    Dingy laundry towels from hard water

    Solution: To help soften the hard water in your home coming from your cistern, specifically your laundry, and help your laundry feel softer, add ½ cup of white vinegar to the rinse cycle. Vinegar acts as a natural fabric softener, breaking down mineral buildup on clothes.

    Reduced Water Pressure and Clogged Plumbing

    Over time, hard water minerals can build up inside pipes, narrowing the water flow and reducing water pressure. This can lead to clogged faucets and showerheads that need constant cleaning to function properly. If the buildup goes unaddressed, it can result in more severe issues, such as pipe corrosion or complete blockages, which can be costly to repair.

    Solution: Installing a water softening system can prevent mineral buildup and protect your plumbing. Regular maintenance and descaling of affected fixtures can also help manage buildup.

    Scale Buildup on Appliances

    Hard water takes a toll on appliances, especially those that use heating elements or handle large volumes of water, like kettles, dishwashers, hot water tanks, and washing machines. The presence of white or yellowish scale deposits on heating elements or around appliance edges is a clear sign of hard water. This buildup can reduce the efficiency of your appliances and shorten their lifespan, potentially leading to expensive replacements.

    Hard water can also build up inside your cistern and pipes. Once you’ve determined that you have hard water, the best way to obtain soft water and get rid of your hard water is to get a water softener. Water softeners use ion exchange to replace calcium and magnesium ions with sodium or potassium ions, reducing water hardness. Will a water filtration system reduce your water flow rate?

    Solution: Use a water softener to protect appliances from scale buildup. For smaller appliances like kettles and coffee makers, run a cleaning cycle with a solution of water and white vinegar to dissolve existing mineral deposits.

    Dry, Itchy Skin

    Washing in hard water can cause dry, itchy skin

    Hard water can affect more than just household items—it can impact your skin. Bathing or washing with hard water can strip away the natural oils from your skin, causing dryness and irritation. The leftover soap residue from hard water further exacerbates this, making it difficult to maintain hydrated, healthy skin.

    Shower head

    Solution: Consider installing a water softener or using moisturizing body washes designed for hard water. Installing a shower filter that reduces mineral content can also help maintain skin health.

    What happens to your PTLevel in hard water?

    Almost all appliances are affected by hard water in some way, and the PTLevel is no exception. The good news is, there is not too much change! To start, the water readings will not be affected by hard water. The PTLevel is designed to monitor the liquid level of water, chemicals, RO tanks, fertilizer tanks, etc; so having hard water is not a problem. We would just recommend making sure the pressure chamber hole does not get blocked by mineral build up annually. If you see build up starting to form, simply scrubbing it off or soaking the pressure chamber in white vinegar will help. Read more about the maintenance here.

    Conclusion: Take Action Against Hard Water

    Spotting the signs of hard water in your cistern or home is the first step toward improving your water quality. From dealing with soap scum and clogged pipes to extending the life of your appliances and preserving your skin health, addressing hard water is crucial. If you suspect your home has hard water, consider testing your water supply and exploring solutions like installing a whole-house water softening system or incorporating simple fixes like white vinegar in your cleaning routines. With a proactive approach, you can maintain a cleaner, more efficient home environment and enjoy the benefits of softened water.

    How to Protect Your Cistern or Well in Winter

    Your PTLevel can handle the winter weather, but is your cistern ready?

    How to Protect Your Cistern or Well in Winter

    In winter your PTLevel can handle the weather, but make sure your cistern can too! Repair cracks, close up gaps, and prevent your pipes from freezing.

    Is your water system ready for winter?

    Why to prepare your cistern or well for winter

    As temperatures start to drop, it’s essential to make sure your water supply system—whether it’s a cistern or a water well—is prepared for winter. Taking the time to winterize your system can prevent costly repairs, maintain water quality, and ensure you have uninterrupted access to water throughout the cold months. Here’s a step-by-step guide to help you get ready.

    1. Inspect and Clean the System

    Before winter sets in, inspect your cistern or well for any signs of wear or damage. This includes checking:

    The tank or well casing for cracks or leaks. If you see a crack, it should be repaired before winter. Plastic tanks and cement cisterns are repaired using different techniques; make sure to reach out to your local cistern specialists for repair.

    Pipes and fittings for signs of corrosion or loose connections.

    The pump for proper operation.

    For cisterns, it’s also a good idea to give the tank a thorough cleaning. Remove any debris or sediment that may have built up over time. This helps maintain water quality and ensures smooth operation throughout the winter.

    2. Insulate Pipes and Tanks

    Another way to prepare your well or cistern for winter is to prepare your water pipes. Freezing temperatures can cause pipes to burst, leading to water loss and costly repairs. Insulate any exposed pipes, especially those running above ground or in unheated spaces. You can use foam pipe insulation or even wrap pipes with heat tape to prevent freezing.

    For cisterns, if your tank is above ground, consider insulating the tank itself or using a cistern heater to prevent freezing. For wells, make sure the well cap and casing are adequately insulated to keep out cold air and moisture.

    3. Check the Pump

    Your pump is a critical part of your water system, and winter can be tough on it. Make sure the pump is properly lubricated and running efficiently. For above-ground pumps, consider insulating them or installing a pump house to protect them from the cold.

    If you use a submersible pump, it’s typically safe from freezing, but you’ll still want to inspect the electrical connections and make sure the control box is secure.

    4. Monitor Water Levels Regularly

    Winter storms and freezing conditions can affect your water supply, especially if you rely on a water well. The PTLevel is an excellent tool for this, providing real-time monitoring of your well or cistern levels. It can alert you if the water level drops too low, so you can take action before running out of water.

    5. Prevent Contamination

    During winter, melting snow and ice can lead to surface water contamination in wells. Ensure your well cap is securely in place and in good condition to prevent water and debris from seeping in. Cistern owners should also check for any gaps or openings where contaminants could enter.

    If you live in an area prone to flooding, consider raising the wellhead above the expected flood level or ensuring the cistern’s lid is properly sealed.

    6. Consider Installing a Backup Power Source

    Winter storms can lead to power outages, which can interrupt your water supply if your system relies on electricity. Having a backup generator ensures that your pump continues to operate even when the power goes out, keeping water flowing in your home.

    7. Test Your Water Quality

    Lastly, it’s important to test your water quality before winter. Cold weather can sometimes impact water quality, especially in shallow wells or cisterns exposed to surface conditions. Testing for bacteria, pH levels, and other contaminants gives you peace of mind knowing your water is safe for consumption throughout the winter months.

    Water Well Level Monitoring

    Water Level History

    How Much Water Do I Have in My Well?

    Understanding how much water is in your well is crucial for managing your household’s water usage. A reliable water level monitoring system can provide real-time data on the amount of water in your well, helping you make informed decisions about your water consumption. The PTLevel not only monitors your well but also offers a running history of up to one month, giving you a clear picture of your well’s water levels over time. In addition, with the ability to send notifications via email or SMS, you’ll always know when your water levels are getting low. Getting notified at a water level that you decide can make all the difference.

    To calculate your well volume: For rectangular prism wells, just measure the length (L) by the width (W) by the height (H). Measurements in cm divided by 1000 gives volume in litres. Measurements in feet x 6.2 gives volume in imperial gallons. To calculate volume of cylinder wells, just multiply π x radius-squared x height.

    For drilled wells as deep as 70′

    How Far Does My Well Level Drop During Usage?

    Have you ever wondered how much your well’s water level drops when you shower, water the lawn, or do laundry? The PTLevel can provide answers by tracking how your well responds to various water demands. By monitoring you can see exactly how much your well is impacted by daily activities. This insight can help you optimize water usage and ensure your well can meet your household’s needs without running dry.

    Fun Fact: It took 73 minutes for a toilet running to drain a 150 gallon RO tank to 24 gallons. Review the 3 pictures below to see how the PTLevel tracked that data and alerted to the problem.

    Are Neighboring Properties Affecting My Well Supply?

    In some areas, multiple properties may draw water from the same aquifer, potentially affecting each other’s supply.
