  • About Your Drinking Water
    October 6, 2019
    2:00 pm - 3:00 pm
    - How does water get to your home? What’s the process to treat it so it's safe to drink? OWASA monitors the water for over 150 substances throughout the year. Their diverse team of scientists, operators, chemists, maintenance crews, and more keep the community’s water system running 24/7, to ensure everyone has it when they need it – about 7 million gallons per day.

    Katie Harrold and Chris Gibbons, OWASA’s Laboratory Supervisor and Technician, will talk about the topics they get asked about most, such as lead and PFAS. Shawn Stanley, Distribution and Collections Coordinator, will explain where OWASA sources the community’s water and how they deliver it to your tap. Linda Low, Community Engagement Officer, will share ways that you can help conserve and protect this natural resource. Thirsty for water knowledge? Join OWASA at this community education session about your drinking water!

    Meeting Room B
  • Forest Management
    October 12, 2019
    2:00 pm - 3:00 pm
    - OWASA owns 2,400 acres of forested lands, most which is in the Cane Creek watershed near Chapel Hill. Cane Creek Reservoir is a main water source for Carrboro-Chapel Hill. Protecting the Cane Creek watershed helps safeguard water quality for our community. Sustainable forest management facilitates this protection, plus provides other environmental benefits such as reducing the risk of wildfire.

    Join Ruth Rouse, OWASA’s Planning Manager, and Ed Kerwin, Executive Director, as they share OWASA’s new vision and approach to forest management: informed by science-based practices and led by guiding principles co-created with community partners and neighbors. They will also highlight recreational activities available to you at Cane Creek, plus ways you can help protect the water too.

    Meeting Room B
  • Reusing Water in Space
    October 19, 2019
    2:00 pm - 3:00 pm
    - On Earth, we rely on the water cycle to renew our water supply. In simplest terms, precipitation falls, the runoff flows to the sea or replenishes groundwater, water evaporates, and the cycle begins again. However, as climate change, localized drought and other factors reduce our confidence that we will always have potable water where and when we want it, water reuse is becoming part of the water cycle. Water reuse is the reclamation of wastewater by advanced treatment methods that permit its use for a variety of purposes. The Orange Water and Sewer Authority (OWASA) provides potable water to the Chapel Hill/Carrboro community and process our waster water at the Mason Farm Water Reclamation facility. For the last 15 years OWASA has provided reclaimed water for use on the UNC campus for a cooling water for their air conditioning and for irrigation purposes.

    While it began as a watering source for basic crops or landscape irrigation, and for such industrial uses as cooling water, very recently we have begun to apply very sophisticated wastewater treatment processes on a wide scale. Through a process called direct potable reuse (DPR) we can use the recycled water as a water supply resource.

    Astronauts on board the International Space Station (ISS) can teach us a lot about water reuse. On ISS, astronauts like my astronaut friend Ricky Arnold eat and drink many of the same foods we do, but their urine, humidity condensate and other system waters is then recycled in a specially built recycling unit. This treatment unit has many similarities to the “earthly” units that produce DPR. We will learn about the similarities that OWASA and ISS share in the story of water reuse in this talk.

    Water reuse has obviously played an important part in making space exploration possible. Here in the United States it will play an increasingly key role in the water portfolio adopted by utilities and the agricultural community in the decades ahead. Educating the public about the importance of reclaimed waters will be a significant challenge.

    BIO: Dr. Alan Rimer has had a varied career in environmental engineering. In the course of over 50 years of professional experience, he has been involved with the planning and design for a variety of water reuse, water resources, wastewater treatment, and other projects. This work has been conducted for local, state and federal governments, as well as a wide variety of industries. He has been served as a Chapel Hill Town Council member, member and Chair of the OWASA Board of Directors, member and Chair of the Orange County Board of Health, and member and Chair of the Chapel Hill Landfill Owners Group, and the Chapel Hill Planning, Information Technologies and Historic District Commissions.

    Meeting Room A
  • Rain Gardens
    March 21, 2019 - March 22, 2019
    1:00 pm - 2:30 pm
    - A NCSU Cooperative Extension Service agent with expertise in rain gardening will lead a workshop on installing a rain garden and demonstrate example planting techniques at the rain garden outside of the library.

    Why do we need rain gardens? Many of our forests and other vegetated areas are developed into impervious surfaces like parking lots, roads and buildings. As plants are replaced with hard, compacted surfaces, the rainwater is unable to disperse energy and gradually soak into the ground. Instead, this stormwater races across pavement picking up pollutants and sediment as it moves along curbs and ditches to storm drains; which empty directly into local waterbodies.

    What are the benefits of rain gardens? - Easy to design, install and maintain - Come in all shapes and color schemes - Provide aesthetic appeal while blending into landscape - Provide habitat for wildlife, butterflies and beneficial insects - Absorb nutrients and some heavy metals - Enhance infiltration, stabilize soil and minimize runoff to storm drains Meeting Room B
  • Rain Barrel Workshop
    March 22, 2020
    1:00 pm - 2:30 pm
    -
    Space is limited to build your own own rain barrel! Staff from the library, the Town's Stormwater Management team, and OWASA will show participants how to conserve water and help protect local waterways. 30 barrels and hardware will be provided free courtesy of Durham Coca-Cola Bottling Co. and River Network. Each household may have one barrel.
