Water Options

Method

Preparation

  1. 1

    Sanitize and set up dispensers

    Thoroughly wash and sanitize both beverage dispensers (and any pitchers or serving vessels) according to local food-safety guidelines. Rinse well so no sanitizer residue remains.

  2. 2

    Fill and chill waters

    Fill one dispenser with filtered still water and the other with filtered sparkling water (or attach carbonation keg to dispenser). Chill both in a cool place or on ice until serving temperature (around 4–8°C / 39–46°F). If using ice, place dispensers in an ice bin so they stay cold without diluting.

  3. 3

    Prepare optional garnishes

    If offering citrus, slice lemons and limes thinly and place in a small pitcher next to the dispensers. Keep garnishes covered and refrigerated until service.

Service

  1. 4

    Set display and signage

    Place dispensers on a stable table with drip trays under the spigots. Position signage prominently explaining 'Unlimited Still or Sparkling Water — Please Reuse Glasses' and, if relevant, note sustainability message about reducing carbon and glass waste.

  2. 5

    Serve and encourage reuse

    Provide a set of clean reusable glasses or tumblers for guests. Encourage guests to reuse the same glass for refills. If guests bring their own reusable bottles, allow them to refill from the dispensers.

  3. 6

    Handle sparkling water safely

    If dispensing carbonated water from a keg or carbonation system, ensure connections are secure and pressure is controlled. Open and close taps gently to prevent excessive foaming and loss of CO2.

Maintenance & Sustainability

  1. 7

    Monitor levels and refill

    Check water levels regularly and refill dispensers from bulk containers as needed to maintain uninterrupted service. Keep backup chilled water so refilling does not interrupt service.

  2. 8

    Wash and rotate glassware

    Provide a designated spot for used glasses. Rinse and collect used glassware for periodic washing (either by hand using a commercial dishwasher or dishwashing station). Rotate clean glasses back into service to maintain a sufficient supply while minimizing single-use items.

  3. 9

    End-of-service cleaning

    At the end of service, empty and thoroughly clean dispensers and any reusable items. Sanitize and store them dry. Properly label and store any remaining bulk water containers for future use.

  4. 10

    Track and communicate impact

    Optionally, estimate and record how many disposable bottles or glasses were avoided during the event and share this with guests to reinforce the environmental benefit.
