Lane Closures Announced for S. Columbia Street

The Orange Water and Sewer Authority will close two northbound lanes of South Columbia Street near the Carolina Inn and Peabody Hall, starting Friday through September 16.

The lane closures will allow contractors to replace a valve on a deep underground water line.

OWASA announced that the work will be performed during daytime and night hours, including this weekend.

One lane will remain open to vehicles, as well as access to the Peabody parking lot.

Water service to UNC’s Sitterson, Brooks, and Chapman buildings will be interrupted on Saturday, and a sidewalk next to the work site will temporarily be closed.

Should work be delayed due to weather conditions, it will be rescheduled to begin Friday, September 19.

OWASA Cleans, Inspects Carrboro Water Tank

The water tank near Hillsborough and Old Fayetteville roads in Carrboro will be inspected and cleaned beginning Thursday, as part of regular maintenance.

That’s according to an announcement from the Orange Water and Sewer Authority.

OWASA has hired a contractor to perform the work, which is expected to take two or three days, weather permitting.

Preparation begins Monday, as OWASA begins draining the tank.

An additive will be used to neutralize the disinfectant “chloramines,” a compound of chlorine and ammonia in OWASA water, so that fish and amphibians won’t be harmed.

After cleaning, the tank will be disinfected, and water samples will be tested before the tank is put back to use.

According to OWASA, water pressure to customers will not be affected during the process.

Orange County in “Abnormally Dry” Period

It may be hot and dry this summer, but Orange County is certainly not yet experiencing a drought according to the U.S. Drought Monitor and North Carolina Drought Monitoring Council.

Orange County is now listed as being in an “abnormally dry condition”, which is the first stage of a drought, by North Carolina classification.

The Sustainability Manager at Orange Water and Sewer Authority, Pat Davis says this hot and dry period has just come on in the past few weeks and that the Drought Monitoring Council did not have Orange County in any sort of drought stage until just recently.

According to Davis in the month of June, OWASA’s Water Treatment Plant only received 1.23 inches of rainfall, the lowest seen in the month since 1993. June also recorded its fourth lowest amount of rainfall at the Cane Creek Reservoir with 1.5 inches.

“So, is June an indicator of July, August, September, October, November, and December?” Davis asks. “Only time will tell, right? We see rainfall flip around pretty frequently from month to month. But if we see July and August well below normal, then that may be the sign that we’re headed into a condition that increases our potential drought risk.”

Davis says water reservoirs are still at almost 91 percent of their storage capacity, due to a “well above normal” amount of rainfall in May and over the last twelve months.

In reference to Orange County’s last drought in 2008, Davis says residents do not have to worry about water conservation just yet, and that OWASA will be monitoring conditions well into the fall before they are alerted of any significant drop in water reservoirs.

Director of Horticulture at the North Carolina Botanical Gardens, Jim Ward, says even though he has recently had to show extra care to the garden’s plants, he has battled with far worse conditions of high temperatures and low rain in his 35 years at the gardens than what he is seeing now.

“It is causing us to put a lot more time into the watering needs of the plants,” Ward says. “At the Botanical Gardens, we use captured rain water as our primary source for irrigation and we have a well for another part of our garden. We’re needing to tap into those more frequently and for a longer period of time.”

Ward has combated the dry spell and conserved water in the garden by aiming the water at the ground instead of the plants’ leaves. He advises plant owners to do the same and offers more advice to folks trying to preserve their plants during the hot streak.

“Help yourself out by planting the right plant in the right place so that it’s matching the plant’s growing conditions to the specific site you have in mind so you aren’t planting a plant that requires a lot of moisture to be healthy in a dry site. Mulching helps you conserve the moisture that’s in the soil so we encourage you to do that. And plant in the fall, you shouldn’t be out there planting new plants in this kind of condition so wait until the fall; it’s the best time of year.”

OWASA: Ridge Road Traffic Will Continue to Flow During Water Line Work

A plan to close Ridge Road traffic in both lanes between Manning Drive and the Rams Head Parking Deck for a water line replacement project has been canceled, thanks to a contractor who resolved a technical issue.

Orange Water and Sewer Authority had recently announced that both lanes would be closed to through traffic.

But as that is no longer necessary, the contractor will continue to close only one lane in patches between Manning Drive and Boshamer Stadium until the water-line work is completed in mid-August.

Chapel Hill Transit will continue to operate on regular routes through the area, although you can expect some delays. NextBus schedules will also be affected.

OWASA Wins State Award For Clean Water

The Orange Water and Sewer Authority is being honored by North Carolina for its high quality drinking water.

OWASA was one of 38 systems to receive the 2013 North Carolina Area Wide Optimization Award from the state Division of Water Resources’ Public Water Supply section.

Sarah Young is the public information officer for the state Division of Water Resources. She says the award recognizes efforts to enhance the performance of water treatment systems.

“All public water supply systems have to meet very stringent requirements, but these systems met even greater requirements,” says Young.

OWASA won the award due to efforts to reduce cloudiness in the water, also known as turbidity.

Kenneth Loflin, OWASA’s water supply and treatment manager, says the lower level of turbidity makes water safer for consumers.

“You are limiting any opportunity for any type of giardia or bacteria that pass through your filters and get into the system, so it lowers your disinfection by-products and you’re removing more organics from the water,” says Loflin. “It’s an all around safer product.”

This isn’t the first time the utility has been recognized for its clean water-OWASA also received the award in 2010 and 2012.

OWASA Reports Untreated Wastewater Spill In Chapel Hill

OWASA officials say Thursday’s strong rains triggered an overflow of untreated wastewater from a manhole near Brigham Road in Chapel Hill.

About 13,500 gallons were spilled from 8:30 p.m. until 1 a.m. Once waters receded, OWASA workers cleaned and disinfected the area.

OWASA in is the process of designing a new, larger sewer line in the area to to increase capacity. That project is estimated to cost $840,000. Construction will start in late fall.

Lessons Learned From Dan River Coal Ash Spill

As we continue to follow the repercussions from the Dan River coal ash spill, one of the largest in U.S. history, the more than 80,000 OWASA users in our area can be thankful that the water they drink is not supplied by the Dan River or any of its estuaries.

Alan Rimer, Chair of the OWASA Board of Directors, explained that the non-profit agency serving Chapel Hill and Carrboro draws water from three local supplies: the Cane Creek Reservoir, University Lake and the Quarry Reservoir west of Carrboro.

“We are also fortunate in that we do not have any coal ash storage ponds in our watershed. The only power plant we have is the one on UNC’s campus, which handles their ash, or what ash they used to have, in a totally different manner. It was shipped off-site. So, we are protected all the way around,” Rimer said.

The spill happened on February 2 at a former Duke Energy plant in Eden, North Carolina, when millions of gallons of coal ash and waste water were leaked.

On Tuesday, the North Carolina Department of Environment and Natural Resources [DENR] alerted Duke Energy that it was considering changes to its waste water permits for coal ash ponds.

Rimer said that though the coal ash spill does not impact Orange County, there are still lessons to be learned.

In January, thousands of gallons of chemicals contaminated the water supply in Charleston, West Virginia.

Both of these situations, Rimer explained, show the necessity of maintaining properly-working storage outside of chemical tanks in the case of spills.

“If a municipality does not require chemicals that are stored, which could somehow how get into the watershed are properly protected, then you have got a real problem,” he said.

Chemical storage facilities in Orange County comply with federally-mandated regulations by the Environmental Protection Agency, which is enforced by DENR.

“While we do not have a coal ash pile, we do have chemicals that are not dissimilar in their potential to impact our watershed. We look after those very carefully in the county.”

In a WCHL commentary in January, Rimer explained that through the cooperation of local governments, the density and impact of development in our local watersheds are limited by some of the most stringent watershed zoning, streamside buffer requirements, and impervious surface limits in the state. These standards, he said, help to reduce the likelihood of contaminants from reaching area reservoirs.

OWASA Protected From N. Chatham Water Woes

UPDATE: Chatham County has cancelled the boil advisory, confirming that no leak occurred. Here is the county’s full statement, released at 3:04 p.m. Thursday:

“Chatham County Water Utilities has announced that residents in sections of North Chatham no longer have to boil county water before using it for consumption.  The State Division of Water Quality has verified that the water supply meets state standards and does not have to be boiled.
 
A boil water notice was issued yesterday due to an unexpected drop in water pressure affecting specific parts of north Chatham.  Utilities staff found no leaks or technical problems in the water system, but water pressure returned to normal levels.  This  points to the possibility that a private contractor doing utility work in the area may have impacted a water valve.”

Chatham County Public works director David Hughes says Wednesday’s advisory to residents in northern Chatham County was strickly precautionary and that he doesn’t believe there was every a break in the line.

“We don’t believe it was a break,” Huges says. “We suspect it was a contractor who closed some valves and shut off supply, so there was never a break in the line. Our tanks never dropped. We didn’t do anything particular, and the system regained pressure and went back to normal operating. So, the potential for contamination is very low. It’s possible but unlikely.”

Hughes says any time there is a drop in water pressure, water samples are taken to check for contaminants and safety measures are taken ensure no one consumes what is potentially hazardous.

While it takes just a few minutes more, he says the best course of action is to follow the safety instructions when they’re handed our—even when danger is not suspected and it’s just a precautionary step.

“They should boil the water for a minute to two minutes until we get the results back,” Hughes says.

In Orange County, Orange Water and Sewer Authority (OWASA) Board of Directors Chair, Alan Rimer says there are processes in place to protect from such an event.

“We have a number of storage tanks that contain several million gallons of water, and those tanks are managed by…a system of intercommunication between the treatment plant and these tanks,” Rimer says. “So, we can control the rate at which that water is put into the system at a pressure which would never allow for it to drop below a particular pressure level that would require a boil order.”

In fact, Rimer says it could be up to a day before the water system’s pressure drops below a safe level.

“We might ask folks to conserve, but certainly not to boil,” Rimer says.
