BottleChallenge: water refill

Join the refill revolution! Find free water refill spots near you, collect EcoDrops and compete with your team.

Every time you refill your bottle instead of buying a plastic one, something small but real happens. Less waste. Less money spent. And with BottleChallenge, you actually get rewarded for it.

Find free water near you The map shows verified refill points around you: cafes, restaurants, museums, gyms, and other venues that offer free tap water to anyone who asks. Updated by the community, so it keeps growing wherever you go.

Earn real rewards Every refill earns you EcoDrops. Collect enough and redeem them for cinema tickets, theater and museum entries, concert passes, and special offers from local venues. The more you refill, the more you unlock.

See your impact BottleChallenge tracks how many plastic bottles you've saved and shows your cumulative environmental contribution. Share it on social media or just enjoy watching the number grow.
