Water Storage Tanks

Water is something we rely on every day, and when it gets stored in tanks, we expect it to stay clean. But that doesn’t always happen. Contaminated water can smell odd, look murky, or even cause health issues. That’s why keeping a water tank clean and secure matters. Whether it’s used at home, on farms, or in industrial facilities, a tank left unchecked can quickly become a source of serious problems.

Many tank owners don’t realise things can slowly go wrong inside their tanks. You might not see the problem from the outside, but inside, there could be sediment piling up, bacteria spreading, or water reacting with metal or concrete. Taking simple steps now can save a lot of trouble later. The good news is, once you know what to look out for, you can avoid contamination with the right care and cleaning schedule.

Common Sources Of Contamination

Water tanks can seem solid from the outside, but there are still a lot of ways unwanted material can end up inside. Once contamination takes hold, the water’s not safe, and the tank may need more than just a quick rinse. It’s usually a mix of both outside and inside factors that cause the problem.

Here’s what to keep an eye on:

– Debris from above: Leaves, sticks, dust and even animal droppings can get into uncovered or poorly sealed tanks, especially during storms or windy days.

– Pests and insects: Small animals or bugs often sneak in through cracks or loose lids. Once they’re in, they might nest or leave waste behind.

– Rust and corrosion: Parts of the tank, especially if they’re metal, can corrode over time. Bits of rust can mix into the water, not to mention weaken the tank itself.

– Sediment build-up: Fine particles can settle at the bottom over time. They might come from the water source or accumulate as the tank ages. This layer can be a breeding ground for bacteria.

– Algae and bacteria: Sunlight and warm water create the perfect environment for algae. If a tank sees a lot of light inside or sits unused for long periods, bacteria and algae can start to form.

– Poor installation or degraded seals: An old or poorly installed tank might have small gaps, cracked edges or faulty valves that allow contaminants in.

Just one of these risks can quickly put the whole water supply at risk. For example, a rural property that uses its tank for drinking and irrigation might start noticing odours or dark water if leaves and bugs have collected during heavy rains. That’s not something a surface clean will fix. Contamination like that often goes deeper.

Preventative Measures To Avoid Contamination

The best way to handle contamination is to stop it before it starts. A solid routine and a few smart choices can keep water clean over time and give peace of mind. Prevention doesn’t have to be complicated, but it does need to be consistent and suited to the tank’s location, build and use.

Start with these three steps:

– Regular inspections and scheduled cleaning: Tanks should be checked inside and out for cracks, leaks, corrosion or signs of pests. Don’t just wait for visible changes in water colour or smell. A routine inspection, even if everything looks fine, can help catch issues early. Pair it with scheduled cleaning to remove sediment before it gets out of hand.

– Use of climate-appropriate, durable tank materials: Choosing the right tank materials for your climate helps a lot. For areas with extreme heat or heavy rain, tanks should resist temperature damage, UV exposure and moisture seepage. Materials like lined concrete or high-grade plastics can block many environmental hazards and last longer under stress.

– Secure covers and screened inlets or outlets: Tank access points should stay sealed and covered. Screens keep out pests and debris, while still allowing water to flow. A cover blocks sunlight and stops organic matter or insects getting in. Make it tight-fitting and check that it hasn’t shifted over time.

Simple steps like these prevent bigger problems later. Stopping leaves before they enter, sealing gaps before bugs get in, and keeping up with cleaning can go a long way to avoiding serious contamination. Letting things slide is usually where trouble starts.

Role Of Professional Water Tank Cleaning Services

Trying to keep a water tank clean without the right tools or know-how can cause more problems than it solves. Dirt, grime and bacteria often hide in places that are hard to reach unless you’ve got proper equipment. That’s where water tank cleaning services come in. Professionals bring more than buckets and brushes. They bring experience, and that makes a real difference.

One of the main reasons people bring in professionals is to get a proper deep clean. Surface cleaning doesn’t help when there’s sludge sitting at the bottom or biofilm stuck to the walls. Some tanks have years’ worth of build-up that can’t just be scrubbed away. High-pressure systems, vacuum pumps and non-toxic disinfectants are tools you’d probably never have on hand at home or on-site. These make it safer and easier to clean the tank properly.

Beyond cleaning, professionals can spot things that might be missed otherwise. Small leaks, damaged coatings, rust patches, mould or even minor structural cracks can be flagged before they become expensive repairs. So it’s not just about cleaning the tank, it’s about protecting it as well.

Booking regular cleanings also helps keep water quality up to standard. Especially in tanks used for drinking or food prep, this really matters. For tanks on farms or used in irrigation, cleaner water means better crops and less chance of spreading disease. A detailed clean and qualified inspection save money down the line.

Maintenance Tips For Long-Term Cleanliness

Day-to-day care makes a big difference when it comes to keeping tanks clean and working properly. While full cleanouts are needed, small habits help hold things together between those bigger services. Staying consistent is better than waiting for problems to appear.

Some simple things to check regularly:

– Look at lids and access points every few months to make sure seals are tight. Cracked or loose covers can let in bugs, dust and even animals.

– Check overflow pipes and inlets for clogs, rust or exposed edges. These parts are often overlooked and are the first places grime starts to build up.

– Keep the area around the tank clear. Trim any trees or plants nearby that drop leaves or bark into the area.

– Watch for slime or mould forming at the tank base or along its edges. These are signs something might be wrong inside and need checking.

– Clean filters and screens more often, especially after storms or heavy rainfall. These usually pick up debris faster than the main tank.

– If your tank collects rainwater, make sure the gutters and downpipes it connects to are clean and free of damage. Blocked or damaged pipes can funnel dirt or pests straight into the tank.

Doing these things regularly can help you go longer between deep cleans. In one case, a small food producer saw fewer issues with water tests after they began checking seals quarterly. Simple habits like these, when done often, really make a difference over time.

Safeguarding Your Water Supply

Water tanks are made to last, but they don’t run themselves. If no one’s checking on them, tanks will slowly start to fall apart in places you might not see. A smart care plan backed up by routine inspections and proper cleaning keeps water safe and tanks going strong. Most of the time, problems start small, like a build-up of grime or a stray leaf in the wrong spot. But if these aren’t dealt with early, they snowball quickly.

The key is staying on top of it. When you clean tanks regularly and keep up with maintenance, they last longer, and the water stays fresh and safe to use. Whether it’s for homes, farms or businesses, storage tanks in good shape make life easier. Working with a team that knows how tanks behave and where they fail helps pick up on problems sooner.

Choosing experienced help means you’re not just reacting to issues—you’re staying one step ahead. Dirty or damaged tanks can lead to big trouble. Making tank health a normal part of your routine keeps those headaches away. A tank in good condition is something you can trust.

Secure your tank’s longevity and ensure cleaner water by booking routine water tank cleaning services. With regular support from the experienced team at ATM Tanks, you reduce the risk of build-up, blockages and bacterial growth while keeping your system running strong for years to come.
