 The fault is close to, but appears to be separate from, the nearby New Madrid Seismic Zone.The Marianna Water and Sewer Commission directs the Marianna Water Department, which treats and distributes potable water to the residents and commercial users of the city.The Department also owns and operates a wastewater collection system, which collects wastewater from over 4,000 service connections and uses a series of laterals, interceptors and five lift stations to gravity flow wastewater to the Marianna Wastewater Treatment Plant (WWTP).
