Service Notice

Due to mechanical issues with both of our delivery trucks, we are currently unable to deliver water to any of our kiosk.  If your kiosk is out of service, it will remain out of service until the issues are resolved.


Because Monday is a holiday, the truck repair center does not reopen until Tuesday morning, and therefore the earliest estimated time to restore service will be late Tuesday 5/28 or Wednesday 5/29. 


We will update our website as we get information from our truck repair center on Tuesday. 


We apologize for the inconvenience.

Our springs are located in the rolling hills of northern Chester County surrounded by thirty seven acres of virgin woodland. Great Oak is a state approved source which has consistently provided pure spring water since 1913.


Great Oak Spring and Bottling was purchased by K-D Services (parent company of the former St. Lawrence Dairy Co.) in 1980. The bottled water business was expanded into Berks County and included cooler rental and coffee service until 1997, when it was sold to Ephrata Diamond Spring Water Co. The spring itself and surrounding property were retained, and the spring water vending has been in operation since 1998.
