You can use a chlorine-based disinfectant specifically designed for water tanks. Follow the manufacturer's instructions for proper dosage and contact time. Flush the tank: After disinfection, flush the tank with clean water multiple times to remove any residual disinfectant.
Vinegar: Put white vinegar in bowls and place the bowls throughout the room. The vinegar will remove the odor within a couple of days. Cat Litter: Put clean cat litter in small, open containers and place the containers around the room. Make sure you change the cat litter for better deodorization.
The solution is simple: if the water starts to smell, drain it, remove the lid and give it a light scrub with a brush.
While it is important to keep the rain tank closed, it is also important to allow the tank to breathe by not being completely sealed and airtight. Allowing a rain tank to breathe will help to prevent the water from going stale and reduce the chance of stagnation.
Rain barrel users should make sure to clean the barrel with a 3% bleach solution before collecting water to irrigate a vegetable/herb garden. Household, unscented bleach with a 5–6% chlorine solution can be added at the rate of 1/8 teaspoon (8 drops) of bleach per gallon of water.
Vinegar or bleach may be used in small amounts to stifle algae growth. Add 1 cup of vinegar to a full rain barrel or add 1/8 tsp of regular, unscented, liquid household bleach for each gallon of water in the rain barrel, stir, and let it stand for a day or two before using the water.
Pro Tip: If you don't want to use apple cider vinegar, you can use tea tree oil to fight the mildew smell. The antibacterial qualities in tea tree oil will be able to clean the space and eliminate any musty odors.
A foul smell while raining can be a tell-tale sign that your septic tank is full. Heavy rainfall can saturate the soil, preventing your drain-field from working properly. Instead, new wastewater will be forced back through the pipes, producing a foul smell.
Petrichor is the smell of rain. The word comes from the Greek words 'petra', meaning stone, and 'ichor', which in Greek mythology refers to the golden fluid that flows in the veins of the immortals.
Ensure there is proper ventilation to allow air circulation and discourage the growth of anaerobic bacteria. Regularly inspect and clean the tank, ideally at least once a year or more frequently if necessary. Consider using a water treatment system or water purifier to further improve water quality.
If algae blooms occur, you can use different household mixtures to clean your barrel. After emptying the barrel, either a vinegar/water mixture or baking soda/water mixture can be used to scrub the inside of the barrel.
For 55 gallons of water, add 4 1/2 teaspoons unscented liquid chlorine bleach (3 tablespoons if water is cloudy)
Chlorine is the most widely used oxidant to remove odor from water, but at best deemed mildly effective. Oxygen and potassium permanganate are also only mildly effective water treatment solutions. Oxidizers such as ozone and chlorine dioxide are by far the most efficient in eliminating odor from water.
Anything that changes what layers of rock your water travels through can alter the amount of sulfur in it. Drought causes the water table to drop, while heavy rains cause it to rise. Undetected earth tremors cause cracks in the rock, exposing new sulfur deposits or closing up old ones.
Create a mixture of equal parts white vinegar and water. Pour it into a spray bottle and lightly mist the musty-smelling areas of the clothes. Allow the vinegar solution to sit on the fabric for about 15 minutes to help neutralize the odor. Wash with odor-neutralizing products.
Certain bacteria produce sulfur compounds that result in a foul odor similar to rotten eggs. Algae and Biofilms: Sunlight and nutrients can promote the growth of algae and the formation of biofilms on tank surfaces. These microorganisms can contribute to musty or earthy odors.
Simply run cold water through a drain pipe that is not used often to ensure sewage smells do not build. Additionally, poor installation of a vent stack could be the cause. A vent stack needs to be able to release odours freely without rainwater building up in the pipe.
Petrichor is the term coined by Australian scientists in 1964 to describe the unique, earthy smell associated with rain. It is caused by the water from the rain, along with certain compounds like ozone, geosmin, and plant oils.
Vinegar is better at killing mold because it can work on both porous and nonporous surfaces. It also terminates molds at their roots so the mold won't return and is also safer than bleach. You can even combine it with baking soda to make it more effective.

Spray Febreze Air for a quick burst of freshness and to eliminate lingering odors. Or consider purchasing an essential oil diffuser, some scented candles, or fresh flowers to replace that musty smell with something positively lovely.
The best filtration options for making rainwater potable are reverse osmosis and distillation. Mechanical filtration (via a sediment filter or Rusco spin-down system) is also integral to the success of rainwater treatment. A rainwater collection system can catch most large particulate matter like leaves and twigs.
The foam removes any algae or mold that has formed inside the barrel. Just slosh the solution around by rolling the barrel, then rinse and allow to dry before refilling. Hydrogen peroxide can often also be used in place of bleach if you've run out of disinfecting wipes or sanitizing gels.
Once rain enters the cistern from the catchment, it should then be pumped into a holding tank which is air- and water-tight, and from which you draw your water for general use. That way, water doesn't stagnate in the cistern. To make this work properly, you'll want a drain in the cistern.
