Citizens had been under notice since Nov. 16 while the city water department made scheduled repairs to the water tank.
Tests performed by the MSDH indicated the water is now safe to drink.
When a water distribution system loses pressure, contaminants can siphon back into the water supply. In order to turn the source back on, the system must pass a series of MSDH mandated tests.
Repairs were funded by a Small Government Public Facilities Grant approved earlier this fall.
"We saw that there were monies available to improve the sewer and waste system and applied for a grant to help with the improvement costs," said Shelby Mayor Kermit Stanton.
The renovations should improve the city's pumping stations and relief of water backup.
The MSHD recommends the following tips when a boil water notice is lifted:
* Flush faucets for a total of 10 minutes to introduce system water throughout house plumbing (Example: 1 faucet — run for 10 minutes, 2 faucets — run both for 5 minutes, 3 faucets — run each for 3-4 minutes).
* Flush any faucet a minimum of 2 minutes to ensure clearing of the line serving the faucet.
* Discard any drinks, ice, food, etc., made during the boil water notice.
* Rewash any food or drink contact items (knifes, forks, plates, etc.) with "cleared" system water.
* Check water filters (in faucets, refrigerators and elsewhere) and replace if necessary.
* Do not use water from your hot water heater for drinking until several exchanges of the tank have occurred.
* Run dishwasher through a cycle or two before washing dishes.
