 STAGE 1 – WATER CONSERVATION ALERT 

07.22.2019
 STAGE 1 – WATER CONSERVATION ALERT

Bolivia, NC – A Stage 1 Water Conservation Alert remains in effect.

All customers of a public water system anywhere in Brunswick County are affected by Water Conservation Alerts. Brunswick County Public Utilities provides water service in unincorporated portions of Brunswick County as well as the following communities: Boiling Spring Lakes, Bolivia, Calabash, Carolina Shores, Caswell Beach, Sandy Creek, St. James, Sunset Beach, and Varnamtown. Customers of other utilities such as Bald Head Island, Brunswick Regional – H2GO (Belville), Holden Beach, Leland, Navassa, Northwest, Oak Island, Ocean Isle Beach, Shallotte, and Southport are under the same restrictions since these utilities receive their water from Brunswick County Public Utilities.

Under a Stage 1 Water Alert, water system customers are requested to make voluntary adjustments to their water usage habits to appreciably reduce peak demands. (A peak demand of 80% of system production and distribution capacity being targeted). Irrigation demands represent the bulk of non-essential water use, so a primary way that customers may reduce water usage is to limit irrigation. A unified application of voluntary water reductions by all water system users in Brunswick County may help to avoid mandatory water restrictions in the event drought conditions do not lessen.

Specific ways to reduce water usage are as follows:

  1. Use the following recommended irrigation schedule to even out system demands:
  2. Odd address numbers – Tuesday/Thursday/Saturday
    b. Even address numbers – Wednesday/Friday/Sunday
    c. No irrigation on Mondays
  3. Defer all non-essential water use to outside the peak demand hours of 5:00 a.m. to 11:00 a.m; preferably after nightfall.
    3. Don’t overwater your yard. One inch of water per week in the summer will keep most types of grass healthy. To determine how long you need to run your sprinkler to provide 1” of water, place straight edged cans at different distances from your sprinkler and time how long it takes to fill an average of 1” of water in each can. Water occasionally, but deeply to encourage deeper rooting that makes grass more drought/heat tolerant.
    4. Install rain shut-off devices on automatic sprinkler systems.
    5. Don’t water pavement and impervious surfaces.
    6. Limit lawn watering to that necessary for plant survival. Water lawns outside of the peak demand hours of 5:00 a.m. to 11:00 a.m; preferably after nightfall.
    7. Water shrubbery the minimum required. Water shrubbery outside of the peak demand hours of 5:00 a.m. to 11:00 a.m. Use drip irrigation systems in shrubbery beds and around trees to prevent water loss through evaporation.
    8. Use abundant mulch around trees and shrubs to retain moisture.
    9. Plant drought-tolerant grasses, trees, and plants.
    10. Adjust mower height to a higher setting to retain moisture.
    11. Limit the use of clothes washers and dishwashers and when used, operate fully loaded. Operate dishwashers outside of the peak demand hours of 5:00 a.m. to 11:00 a.m; preferably after nightfall.
    12. Limit vehicle washing to a minimum. Use commercial car washes that recycle water.
    13. Use shower for bathing rather than bathtub and limit shower to no more than five (5) minutes.
    14. Inspect and repair all faulty and defective parts of faucets and toilets. Pay attention to dripping sounds.
    15. Do not leave faucets running while shaving, brushing teeth, rinsing or preparing food.
    16. Do not wash down outside areas such as sidewalks, driveways, patios, etc.
    17. Install water-saving showerheads and other water conservation devices.
    18. Install water-saving devices in toilets such as early closing flappers.
    19. Limit hours of water-cooled air conditioners.
    20. Keep drinking water in a container in the refrigerator instead of running water from a faucet until it is cool.
    21. Do not fill new (or empty) swimming or wading pools. Top off existing swimming pools from dusk until dawn.
    22. Cover pool and spas when not in use to prevent evaporation.
    23. Use disposable and biodegradable dishes where possible.

Please note that this Stage 1 Water Conservation Alert does not affect the use of private groundwater wells or those using highly treated reclaimed wastewater. (St. James, Winding River, Sea Trail, and Sandpiper Bay golf courses use reclaimed water. Other golf courses use wells and ponds for irrigation.) Also, this is not a water quality advisory; this is a water conservation advisory. There is no need to boil water for potable use unless you receive a Low Pressure Advisory notice for your specific area due to other conditions in the water distribution system.

Residents will be notified if any other conservation measures are needed and when conditions dictate that restrictions are no longer required. Residents who have questions should contact their water service provider directly or Brunswick County Public Utilities at 910-253-2657.

(EXPIRED) Request for Proposals (RFP): Water Treatment Evaluation

11.28.2017

Five copies of the response to this request for proposal must be submitted to the County by close of business (4:30 p.m.) on Friday, January 5, 2018.

Brunswick County is requesting proposals from qualified engineering, environmental, and water resource firms for the services associated with evaluation of water treatment options at the Northwest Water Treatment Plant (WTP). In order to meet future potable water demands, Brunswick County (County) is seeking to expand the Northwest Water Treatment Plant from 24 mgd to 36 mgd. The raw water source for this facility is the Cape Fear River which has recently been shown to contain a number of contaminants that are difficult to remove by existing treatment technologies. Brunswick County is seeking assistance in determining the appropriate level of treatment and associated treatment technologies to affect the removal and/or reduction of contaminants to safe levels. A recent study authored by Mei Sun et al1, (including Dr. Detlef Knappe), identified multiple perfluoroalkyl (PFAs) substances, including the GENX compound, at elevated levels in the Cape Fear River. Other studies and testing have identified 1-4 Dioxane, Hexavalent Chromium, N-Nitroso-dimethylamine (NDMA), and Pharmaceutical Personal Care Products (EDC/PPCPs) in the Cape Fear River watershed. Based on these recent studies and ongoing concern of these contaminants, most unregulated, appearing within the raw and finished water of various drinking water systems in the Cape Fear region, the North Carolina Legislature enacted House Bill 56 “GENX Response Measures” to assist utilities in monitoring, treating, and studying these contaminants. Cape Fear Public Utility Authority has been designated to take the lead on this endeavor and they have enlisted Black & Veatch to provide engineering services. However, much of these studies focus on CFPUA’s Sweeney Water Treatment Plant and Brunswick County requires additional engineering analysis based on the existing treatment methods and layout of its Northwest Water Treatment Plant.

SCOPE OF WORK
Water Treatment Evaluation

  1. Review House Bill 56, the ongoing UNC-Wilmington contaminant identification study and testing results, Black & Veatch’s technical memoranda (1 & 2 currently complete, others ongoing), the Mei Sun et al technical bulletin “Legacy and Emerging Perfluoroalkyl Substances Are Important Drinking Water Contaminants in the Cape Fear River Watershed of North Carolina”, Brunswick County’s Annual Water Quality Reports, EPA’s Unregulated Contaminant Monitoring Rules (all), NCDEQ’s 1,4 Dioxane Study, and any other studies or documents that may be useful in determining contaminants, whether regulated or not, that exist in the raw water now, or are likely to exist in the future, that pose a health risk or potential health risk. The County’s Web site lists many of the studies that are ongoing at www.brunswickcountync.gov/genx. Evaluate and group contaminants indicating those persistent contaminants that are not likely to be sufficiently removed or reduced by the current Northwest Water Treatment Plant technologies.
  2. For each contaminant provide the Maximum Contaminant Level (MCL) or Health Advisory Level if available. Many contaminants will not have an MCL or Health Advisory established and may not have any established for the foreseeable future. For the persistent unregulated contaminants identified in (1) above, provide a discussion and recommendations of potential treatment goals that may be used in the evaluation of treatment methods.
  3. Develop a list of additional treatment additions or modifications (Carbon Filtration, Reverse Osmosis, Nano-filtration, Oxidation, Ion Exchange, etc.) that may be successful in removing persistent contaminants. Perform high-level evaluation of treatment alternatives, including advantages and limitations. Meet with regulatory agencies to provide specific guidance on permitting issues. Permitting requirements for the wasting of spent carbon containing contaminants should be assessed. Also, permitting requirements for the disposal of the reject concentrate stream of Reverse Osmosis should be evaluated. Any potential long-term liabilities due to contaminant disposal should be evaluated. Based on this information, provide workshop with County and provide recommendations for treatment options that may be eliminated from consideration and those that should be evaluated further through pilot testing.
  4. Provide testing strategy and perform testing that simulates full-scale drinking water treatment system. Discuss laboratory services and how they may be integrated into the overall evaluations. Evaluate testing and provide analysis and treatment recommendations for each technology evaluated.
  5. For promising treatment alternatives, develop implementation strategies indicating required size, placement, and integration of new processes within the Northwest WTP. Consideration should be given for an ultimate expansion to 48 mgd at the Northwest WTP. Prepare a high level cost opinion for each selected alternative that includes lifecycle costs inclusive of O&M, electricity, media/filter replacement, etc. Carbon costs shall include any necessary disposal/recycling costs to ensure proper disposal of contaminants. Provide recommendation and conduct a workshop with Owner to discuss recommendations. Work products shall be sufficient to provide Brunswick County direction on the best treatment options available for installation at the Northwest WTP along with the estimated costs and effectiveness of those treatment technologies.
