+# getWaterSamples
+
+Get the total amount of consumed water in litres for a specific time period
+
+Example input options:
+
+```javascript
+let options = {
+    unit: 'litre', // optional: default: litre
+    startDate: new Date(2021, 0, 0).toISOString(), // required
+    endDate: new Date().toISOString(), // required
+    includeManuallyAdded: false, // optional: default true
+    ascending: false, // optional; default false
+    limit: 10, // optional; default no limit
+}
+```
+
+Call the method:
+
+```javascript
+AppleHealthKit.getWaterSamples(
+  (options: HealthInputOptions),
+  (err: Object, results: Array<HealthValue>) => {
+    if (err) {
+      return
+    }
+    console.log(results)
+  },
+)
+```
+
+Example output:
+
+```json
+[
+ {
+    "id": "3d366e60-4f7c-4f72-b0ce-479ea19279b8", // The universally unique identifier (UUID) for this HealthKit object.
