POWAY, Calif. (KGTV) -- Residents and businesses in Poway are hoping they will finally have clean water Friday after a boil water advisory and order to stop using tap water was issued for the city nearly a week ago.

On Thursday, another round of testing was conducted on Poway’s water supply and samples were sent to be examined by state officials.

City officials said the first test on the water, requested by the state, came back clean.

In a tweet Thursday evening, the city said: “To clarify, we’ve had multiple tests so far -- all meeting standards. This 1 of 2 required by the state post repairs. Last test results expected tomorrow.”

Poway has been under a boil water advisory since Nov. 30 after numerous residents reported brownish water coming out of faucets the day before.

The city’s Public Works Department said it secured the stormwater outlet on Dec. 1 to eliminate any future backflow.

The affected section of Clearwell Reservoir was disinfected and refilled earlier this week, the city said.

As the city awaits the results of the second round of state-mandated tests, bottled water will continue to be given to residents until the boil water advisory is lifted.

The city released the following information on what residents should do once the boil water advisory is lifted:

When I turn on the faucet, the water sputters. Why?
-- You may have air in your lines. Turn on your tap slowly and run the water until the sputtering stops.

The water is discolored. What should I do?
-- Flush water pipes by running the water until it is clear. Do not wash clothes if the water is discolored. Wait until the water runs clear at the tap. Wash a load of dark clothes first.

What should I do if my water pressure is low?
-- Check the faucet screens for trapped particles. Remove the screens and clean out any particles. Put the screens back on the faucet.

Do I need to clean out my faucets?
-- Yes. You should flush your faucets after the drinking water advisory.

Turn on the main water valve.
Turn on the cold water tap at all faucets and run the water until you feel a change in temperature (i.e. the water gets noticeably colder). This may take several minutes. Begin with the faucet that is highest up in your home or building and then open the other faucets one at a time moving from the highest floor to the lowest.

Do I need to clean appliances?
-- Yes. Read the owner’s manual for directions to clean appliances such as water softeners and filter units.

My refrigerator has a water dispenser/ice maker. Do I need to clean them?
-- Yes. Water dispensers and ice makers are connected to your water line. You need to flush and clean them.

Follow the directions in the owner’s manual or:
-- Change the filter cartridges.
-- Throw out ice.
-- Flush the water dispenser for 3 to 5 minutes.
-- Run the ice maker for 1 hour.
-- Throw out all the ice.
-- Wash and sanitize bin areas.

Do I need to do something for the water softener?
-- Yes. You may need to run through a regeneration cycle. Follow the directions in the owner’s manual.

I have a water treatment unit for the house. Does it need special care?
-- Yes. Change the filter cartridges. Some units need disinfecting. Follow the directions in the unit’s owner’s manual.
