The Cooperative is a member of South Dakota One Call, a communication link among utilities, contractors, and private individuals who work with or around underground lines or pipes. If you plan to dig a hole or trench more than a foot deep on you property, you must phone South Dakota One Call (811) or 800-781-7474 if you live outside South Dakota, at least 48 hours before you plan to excavate. They have up-to-date records on electric, gas, phone and other utilities. They can help you avoid loss of service by accidentally severing one of these lines or pipes. Your call may also avert a possible serious incident.
