Proper pool water storage during repair is crucial not only to preserve your investment but also to support environmental sustainability and comply with local water regulations.
In this article, we’ll explore the various methods for storing pool water while repairs are underway, the right containers and techniques to use, as well as safety and environmental considerations. By the end, you’ll have a solid understanding of how to manage one of the most critical components of pool maintenance: handling your pool water responsibly.
Why Storing Pool Water During Repair Matters
When undertaking major pool repairs, it’s often necessary to drain a large portion, if not all, of the water in your swimming pool. However, simply letting the water go to waste or dumping it without care can have several negative consequences. Storing pool water correctly ensures:
- Cost efficiency – Reusing water saves on refilling expenses.
- Chemical balance preservation – Stored water retains its already balanced chemistry, saving re-treatment time.
- Environmental responsibility – Water conservation is increasingly important in many regions.
- Regulatory compliance – Many areas impose restrictions on water discharge and usage.
If you’re considering draining your pool during a repair, especially in drought-prone areas or regulated municipalities, it’s essential to handle the water properly.
Can You Refill Water From Storage?
Yes! Many pool owners are surprised to learn that if pool water is stored correctly (sealed and maintained), it can be refilled back into the pool after repairs. This can be a financially sound and eco-friendly solution as long as contamination is avoided.
Assessing Water Quality Before Storage
Before deciding to store your pool water, assess its overall condition. Pool water that has been maintained with regular chemical balancing and filtration is far more suitable for storage than neglected water.
Key Factors to Consider:
- Chemical levels – Ensure that chlorine, pH, and alkalinity are within acceptable levels.
- Clarity and debris – Water should be free of large contaminants or visible floating particles.
- Microbial content – Test for bacteria levels, especially if the water has been stagnant.
If the water is unclean or has been unattended for a long time, you might be better off discharging it responsibly and refilling with fresh water. However, if the pool water has been regularly maintained, it can be a tremendous resource to store and reuse if handled correctly.
Choosing the Right Storage Containers
Not all containers are suitable for holding pool water for extended periods. Selecting the right storage solution is essential to avoid evaporation, contamination, or water degradation.
1. Rainwater Tanks and Large Water Tanks
High-quality, food-grade plastic or polyethylene water tanks are ideal for short- to medium-term water storage. Many tank manufacturers produce UV-resistant containers that reduce evaporation and algae growth.
2. Water Bladders (Collapsible Tanks)
These are portable, collapsible containers designed for temporary water storage and transport. Available in various sizes, water bladders are:
- Easy to set up.
- Cost-effective for large pools.
- Space-saving when not in use.
3. Truck-Mounted Water Tanks
For larger in-ground swimming pools requiring full drainage, you may want to use a professionally sourced water removal and storage service. Many pool repair companies offer mobile water transport and storage systems that safely hold large quantities of chemically safe water for reuse.

Preparing for Storage: The Right Way to Drain and Transfer Pool Water
Before water is stored, it must be properly drained and transferred using the correct equipment and following best practices.
1. Drainage Location and Permits
Local ordinances may regulate where you can discharge or store large quantities of chemically treated pool water. For instance, chlorine and saltwater may be hazardous to plants, animals, or sewer systems.
Contact your local water authority or municipality before draining as you may need a permit or be directed to an appropriate draining zone.
2. Use of Submersible Pumps
To preserve the pool’s internal structure during drainage, consider using submersible pool pumps or trash pumps that can extract and transfer water efficiently without damaging the pool lining or shell.
Recommended Pumps for Pool Water Transfer
- Submersible Dirty Water Pump – ideal for small-to-mid pools
- Truck-mounted transfer pumps – for large in-ground pool drainage
- Energy-efficient sump pumps with filtration pre-treatment
3. Water Filtration During Transfer
As water is being pumped out of your pool and into storage tanks, filtering it can greatly improve its suitability for future use. A simple sand filter or portable water filter system can remove residual debris and dirt from the pool surface or bottom.
Storage Best Practices: Keeping Your Pool Water Clean and Usable
Storing the water correctly involves more than just placing it in a container. Maintaining its quality during temporary storage requires a few tactical steps.
1. Keep Storage Containers Covered
Avoiding sunlight exposure is one of the most important steps in storing pool water. Sunlight encourages algae growth, which can quickly render the water unfit for reuse.
Use light-blocking lids or tarps when using open or collapsible systems. Some plastic tanks come with opaque or colored shells specifically to reduce UV penetration.
2. Introduce Bacterial Control
Even stored water can develop algae or bacteria over time. To prolong water usability, consider applying a small amount of liquid Algicide or algaestat before storage. However, be cautious about introducing strong chemicals without knowing when reuse will occur.
3. Maintain a Stable Environment
Avoid placing water storage tanks in high-traffic or unstable regions. If stored outside, ensure the containers sit on flat, level ground and are protected from elements like high winds or excessive heat.
4. Check and Maintain Regularly
If water is to be stored for more than a few weeks, check its condition every 7–10 days. Re-test chemical levels and clarity, and if necessary, introduce minor treatments (like a quick filtration or small chlorine boost) to maintain usability.
Reusing Stored Water: When and How to Refill
Once the repairs are complete, you may be ready to put the stored water back into your pool. However, water reuse isn’t as simple as redirecting a hose—there are steps you need to take to ensure safety and clarity.
1. Re-testing Water Quality
Before refilling, test and adjust your stored water’s:
- Chlorine levels
- pH balance
- Total alkalinity
- Calcium hardness
You may find that even if drained correctly, the stored water has shifted in chemical composition. Use a portable test kit or have a sample analyzed professionally.
2. Inspect the Pool Before Refilling
Ensure that the repaired structure is water-tight and that all systems—including your new filter, pump, and lines—are functional. It’s also wise to give the pool a quick clean before reintroducing stored pool water.
3. Gradual Refill and Circulation
Instead of dumping all stored water into the pool in one go, try filling your pool gradually, using filtration and water testing equipment to monitor condition changes. Running the filtration system for a few hours during and after refill helps stabilize the water chemistry more effectively.
Alternative Water Disposal & Municipal Guidelines
In some cases, you might find that storing your pool water is not the most practical solution. This might occur if:
- Repairs require full pool demolition or component replacement.
- Water was unbalanced or heavily contaminated before drainage.
- Storage options are unavailable or too costly.
If storage isn’t right for your repair scenario, you still must follow guidelines for:
- Municipal wastewater discharge – avoid dumping into storm drains.
- Ground infiltration – water must be neutralized first.
- Environmental protection – prevent runoff into waterways.
Cost Considerations of Pool Water Storage During Repairs
Storing water for reuse involves an investment in both time and money. It’s essential to consider your specific situation:
DIY vs. Professional Services
For smaller pools, storing water in a handful of large plastic drums or using collapsible tanks may be very affordable and manageable. However, larger pools often require rental of water bladders or hiring professional water hauling services, which can run from $200 to $1,000 or more depending on location and storage duration.
Water Conservation Incentives
Be aware that some local governments or water districts offer rebates or programs for those who practice water conservation. If your pool repair includes storage and reuse of water, check whether you qualify for financial incentives or tax credits.

If you’re preparing for a pool repair project, assess whether storage is a viable option, choose your equipment wisely, and don’t hesitate to consult with professionals who can guide you through the process. With a little effort, you can keep every valuable drop of water from going to waste.
Why is it important to store pool water properly during repairs?
Properly storing pool water during repairs helps maintain water quality, reduces waste, and saves money by avoiding the need to refill the pool entirely. When pool water is left exposed or improperly stored, it can become contaminated with debris, algae, or bacteria, making it unsuitable for reuse. By preserving your existing pool water, you also retain a significant portion of the chemical balance, which reduces the effort and cost required to rebalance the water after repairs are complete.
Additionally, responsible storage of pool water is environmentally friendly, conserving a valuable resource and minimizing the strain on local water supplies. This is particularly important in areas experiencing drought or water restrictions. Proper storage also ensures safety by preventing water from becoming a breeding ground for mosquitoes or posing a risk of flooding or property damage. Understanding how to store pool water correctly is essential for a smooth, efficient, and eco-conscious repair process.
Can you keep the water in the pool during repairs?
In many cases, it is possible to retain the water in the pool while performing minor repairs such as patching small cracks or replacing fixtures. However, for extensive repairs like liner replacement, structural fixes, or draining the pool for winterization or major renovations, the water may need to be removed and stored temporarily. Keeping the water in during light repairs can save time and resources, but it is crucial to ensure that the water remains covered and chemically balanced to prevent contamination.
If water must be removed, it should be stored in a clean, covered container or a designated area to protect it from dirt, debris, and sunlight. A large polyethylene tank or lined above-ground pool is suitable for this. It’s important to test and adjust the water’s chemistry before storage and again when refilling the pool to avoid issues like algae growth or corrosion. Storing water properly when it must be removed ensures a quicker return to a swimmable environment post-repair.
What are the best containers for storing pool water?
The best containers for storing pool water are large, food-grade polyethylene tanks that are BPA-free and safe for water storage. These tanks are durable, often resistant to UV light and temperature fluctuations, and can be found in various sizes to accommodate different pool capacities. Other options include clean, empty IBC (Intermediate Bulk Containers) or commercial water storage bladders designed for non-potable water, provided they are properly sanitized before use.
It’s important to store the water in a shaded area to reduce evaporation and minimize algae growth caused by sunlight exposure. Containers should be covered with a tight-fitting lid or tarp to keep out debris, insects, and animals. If the water is to be stored for an extended period, adding a small amount of chlorine or using algaecide can help maintain its quality. Choosing the right container and maintaining proper storage conditions ensures that the water remains viable and safe for reuse after repairs.
How long can you store pool water before it goes bad?
Pool water can typically be stored for up to 7-10 days without significant deterioration, provided it is kept in clean, covered storage containers and protected from sunlight and contaminants. During warmer weather, the duration may be shorter due to increased risk of algae growth and bacterial activity. Properly maintained storage conditions, including periodic chemical testing, can extend this timeframe and preserve water quality for reuse.
After two weeks, even with chemical maintenance, pool water may begin to lose its effectiveness due to evaporation, contamination, or chemical breakdown. At this point, it’s generally recommended to treat or partially replace the water to ensure it remains safe and balanced for use. Knowing the limits of water storage helps pool owners plan repairs effectively and avoid unnecessary costs associated with discarding and replacing large quantities of water.
How should I treat the water before storing it?
Before storing pool water, it’s essential to test its chemical balance and adjust it to ensure it remains stable during storage. Focus on maintaining proper pH levels (7.2–7.6), total alkalinity (80–120 ppm), and chlorine levels (1–3 ppm). A balanced water composition reduces the likelihood of algae growth and corrosion during storage. You may also consider adding a non-metallic algaecide for extra protection, especially if the water is to be stored for more than a few days.
In addition to balancing chemicals, ensure the storage container is clean and free of contaminants. If the pool water is cloudy or contains debris, it should be filtered or clarified before storage to improve its quality. Using a pool cover or sealing the container will further protect the water from environmental pollutants. Taking these steps before storage preserves the water’s integrity and ensures it remains a valuable, reusable resource post-repair.
What should I avoid when storing pool water during repairs?
One major mistake to avoid when storing pool water is leaving it exposed to direct sunlight or open environments, which can encourage algae growth and accelerate chemical evaporation. Also, don’t use containers previously used for chemicals, oils, or non-potable water, as they may leach contaminants into the stored water. Avoid overfilling storage tanks without accounting for temperature changes and evaporation, which can lead to overflow or structural damage.
Another common pitfall is neglecting to monitor water levels and chemistry during the storage period. Failing to check on stored water can result in sudden pH fluctuations, increased metal content, or contamination that may render the water unsuitable for reuse. It’s also unwise to store water for extended periods without any chemical maintenance, even if containers are sealed. By avoiding these mistakes, you’ll help ensure safer, cleaner water for reuse and a smoother pool repair process.
Can I reuse stored pool water without chemical treatment after repairs?
Reusing stored pool water without re-testing and re-balancing the chemistry is not recommended, even if the water appears clean. During storage, evaporation, temperature changes, and potential contamination can alter chemical levels, compromising the water’s safety and quality. Before refilling the pool, test the pH, chlorine, alkalinity, and calcium hardness to ensure they are within acceptable ranges. Adjusting these levels will prevent discomfort for swimmers and protect the pool’s surfaces and equipment.
Additionally, check the water for cloudiness or odors, which may indicate algae or bacterial growth. If the water has been stored for longer than two weeks or shows any discoloration, it may require partial replacement or shock treatment to restore clarity and sanitation. Even if the water seems usable, adding a fresh dose of sanitizer and adjusting stabilizers can ensure it remains healthy and safe for swimming. Treating stored water properly before reuse helps maintain a clean, balanced, and enjoyable pool environment.
