How much water does your workplace need? A practical 15L bottle guide
If you run an office, warehouse, workshop, depot or other busy workplace in regional NSW, one of the first questions is usually straightforward: how many 15L spring water bottles should we order?
Order too little and the cooler runs dry before the next delivery. Order too much and you are using valuable storage space for bottles your team is not getting through.
The table below gives you a practical starting quantity for a four-week delivery cycle. It is designed for workplace ordering, not as a medical hydration formula. Once deliveries begin, Summer Springs can adjust the quantity using your actual bottle usage.
The simplest approach:
Choose the closest team-size range below, then decide whether the cooler will be used by employees only or by employees and customers.
The quantities represent estimated use over four weeks. Where a larger order would be difficult to store or handle safely, we may divide it across fortnightly or weekly deliveries.

1) How the workplace water guide works
Workplace water usage varies. A quiet professional office may use less water than a workshop with the same number of employees. A dealership, medical practice or reception area may use more because customers and visitors also have access to the cooler.
The guide gives you two starting points:
- Employees only: suitable for staff rooms, offices and internal workplace areas.
- Employees and customers: suitable for showrooms, reception areas, waiting rooms and other customer-facing locations.
The quantities are deliberately practical rather than overly precise. They help you establish a sensible first order, which can then be adjusted once your normal usage becomes clear.
2) Suggested 15L bottle quantities
Use the table to estimate the number of returnable 15L spring water bottles your workplace may use over four weeks.
| Employees at Location | 15L Bottles (Employees Only) |
15L Bottles (Employees and Customers) |
50-Cup Sleeves |
|---|---|---|---|
| 1 to 5 | 2–3 | 3–4 | 1 |
| 6 to 10 | 5 | 10 | 2 |
| 11 to 15 | 8 | 15 | 3 |
| 16 to 20 | 10 | 20 | 4 |
| 21 to 30 | 20 | 30 | 5 |
| 31 to 40 | 30 | 40 | 8 |
| 41 to 50 | 45 | 50 | 12 |
Suggested usage over a four-week delivery cycle. Actual requirements vary according to weather, workload, roster patterns, customer numbers and site layout. Where a location requires more than 10 bottles over four weeks, Summer Springs will generally recommend fortnightly delivery to support safer storage, better stock rotation and easier handling.
3) How delivery frequency affects your order
The quantities in the table represent estimated total usage across four weeks. This is often referred to as monthly delivery, although the Summer Springs route returns every four weeks rather than on the same calendar date each month.
Your actual quantity at each delivery will depend on how frequently the route services your location.
- Four-weekly delivery: the full suggested quantity is generally delivered at once.
- Fortnightly delivery: the four-week quantity is generally divided across two deliveries.
For example, a workplace estimated to use 20 bottles over four weeks may receive approximately 10 bottles per fortnight. A higher-volume location may be better suited to weekly delivery so there are fewer heavy bottles stored on site at one time.
The available frequency will depend on your location and the local Summer Springs delivery route.
4) How we fine-tune your quantity
The starting table is useful, but your actual bottle returns tell us much more.
After your first few deliveries, we can adjust the order based on:
- How many empty bottles are returned
- How many full bottles remain on delivery day
- Changes in employee numbers
- Customer or visitor use
- Seasonal demand
- Different shifts or operating hours
- The number of coolers or hydration points across the site
- Your feedback to the driver or customer service team
How adjustments generally work:
- Running low before delivery day? We can increase the quantity or review the available delivery frequency.
- Full bottles are accumulating? We can reduce the quantity, change the delivery frequency or do both.
- Your team has grown? We can increase the standing order without requiring you to start again.
- Summer demand has increased? We can increase the quantity temporarily and review it when conditions ease.
The aim is to keep your workplace reliably supplied without creating unnecessary bottle storage or leaving water sitting unused for long periods.
5) When your workplace may need more water
The employee-only column is most suitable for offices and light-duty workplaces. Your site may use more water where employees are exposed to heat, complete physical work or spend time outdoors.
Consider starting higher, or speaking with our team, if your workplace includes:
- Warehouses, workshops or manufacturing areas
- Outdoor work or regular exposure to high temperatures
- Multiple shifts or overlapping crews
- Contractors and temporary workers
- Customers or visitors using the same cooler
- Several separate buildings or work zones
- Seasonal peaks in staffing or production
- Remote locations where an extra delivery is difficult to arrange
For hot, physically demanding or remote workplaces, this guide should support, not replace, the organisation’s formal heat-management and workplace hydration planning.
6) Practical workplace hydration setup tips
How the water cooler is set up can affect how much water employees actually drink and how easy the supply is to manage.
- Place water near the work area. A cooler in a distant lunchroom may not be convenient for warehouse, workshop or outdoor staff.
- Use multiple hydration points where needed. Separate office, warehouse and customer areas may each need their own cooler.
- Store replacement bottles safely. Keep bottles upright, secure and away from direct sunlight or chemicals.
- Consider a bottle storage rack. A rack can keep full and empty bottles organised where floor space is limited.
- Keep cups easy to access. Customer-facing coolers are more useful when clean cups are clearly available.
- Assign responsibility. Nominate someone to check stock, change bottles and keep the cooler area tidy.

8) Frequently asked questions
Are the quantities in the table monthly or per delivery?
The table shows estimated usage across four weeks. For a customer on a four-weekly delivery route, that will generally be the starting quantity delivered at each visit. Customers on fortnightly or weekly delivery will usually receive the same overall quantity divided across more frequent visits.
How many 15L bottles does a 10-person office need?
A 10-person office can start with approximately five 15L bottles every four weeks for employees only. If customers and visitors also use the cooler, approximately 10 bottles every four weeks may be more suitable.
These are starting quantities. Summer Springs will work with you to adjust the order if your actual usage is higher or lower.
What if our workplace has uneven shifts, contractors or lots of visitors?
Use the number of employees who are consistently on site, then consider contractors, visitors, shift overlaps and busier operating periods. The employee-and-customer quantity may be the better starting point where the cooler is widely accessible.
What if we operate a warehouse, workshop or outdoor site?
Physically demanding, hot or outdoor workplaces may require more water than an office with the same number of employees. The guide can still be used as a starting point, but the quantity should be reviewed against actual site conditions and usage.
What does monthly delivery mean?
Summer Springs uses the term monthly to describe a four-week delivery cycle. This means the driver returns every four weeks, rather than on the same date of each calendar month.
Why might Summer Springs recommend fortnightly delivery?
Where a workplace uses more than approximately 10 bottles over four weeks, fortnightly delivery can reduce the number of bottles stored at one time. It can also improve handling, stock rotation and the organisation of full and empty bottles.
Do we need a water cooler?
A cooler is not the only way to dispense bottled water, but it provides a cleaner and more convenient workplace setup. Summer Springs offers cooler purchase, rental and discounted water cooler starter packages.
How will we know whether our starting quantity is right?
Look at the number of full and empty bottles remaining when the next delivery arrives. If the workplace repeatedly runs low, increase the order. If unused bottles continue to accumulate, reduce the quantity or review the delivery frequency.
Does Summer Springs deliver to our area?
Visit the Summer Springs delivery areas page or contact our team to confirm the route and available delivery frequency for your town or property.
This article provides general ordering and stock-planning guidance for workplace drinking water. Actual requirements vary according to weather, workload, roster patterns, customer numbers and site layout. Workplaces should separately assess their health, safety and heat-management obligations.
