THOMASVILLE — People going door to door offering water-testing services do not represent the City of Thomasville.
"They are a private entity trying to make money," said Chris White, executive director of city public utilities.
Attempts to sell water-purification systems are not being done on behalf of the city, White added.
He said water-purification systems for city water are not required for health purposes.
The people making door-to-door contacts do not have a city peddling permit, which is required for contacting residents.
The city water treatment plant houses water pumps and wells. The pumps draw water from the aquifer from 294- to 466-feet-deep wells.
Non-potable water is prevented from entering the city water system, White said.
More than 1,000 fire hydrants provide the water supply for fire-fighting. A typical home uses seven gallons of water to flush a toilet and up to 50 gallons of water for a five-minute shower.
