Nature preserve park reuses wastewater
- Tom Smith
Annie Louise Wilkerson was the first female ob/gyn in Raleigh, North Carolina and delivered more than 8,000 babies during her 53-year career in which she was known as a pioneer for her achievements in the medical community as well as her philanthropic contributions to her local community.
Upon her death, Dr. Wilkerson donated 157 acres of land in North Raleigh, adjacent to Falls Lake. As her will states:
- That the property herein conveyed shall be maintained as a nature preserve park, and used for the primary purpose of nature and wildlife education.
- That no buildings other than those existing at my death shall be erected or maintained on the property other than shelters for necessary service and educational buildings.
One new building has been constructed on site to provide bathrooms for the park visitors. One of the existing houses has been renovated and re-purposed as the park office
Given the stipulations of Dr. Wilkerson's will, it was agreed that buildings, as well as wastewater treatment for the bathrooms should be self-sustaining.
Funding was provided by the City of Raleigh. The will granted the property and added the stipulations. The city involved Wilkerson family members in the decision-making process.
There are two sources of wastewater:
- The comfort station (200 visitors at 5 gallons/day/visitor)
- The park office (6 employees at 25 gallons/day/employee) for a total flow rate of 1,150 gallons per day
PuraMC was chosen as the wastewater treatment and water reuse system for toilet flushing and dispersal into the drip field as membranes provide a physical barrier that ensures the treated wastewater meets the exceptional quality required for reuse applications.
PuraMC is Anua's compact version of its flat plate membrane cassette designed specifically for the emerging residential and commercial water reuse markets. Each cassette is designed to treat 300 gallons per day while providing a solution that is robust and easy to maintain in comparison to other membrane systems.
PuraMC provides treated wastewater that is much cleaner than required for reuse.
As water becomes more precious, there is a tremendous opportunity to use wastewater management technologies to improve the quality of the effluent so treated wastewater can be used, reduce the use of potable water and improve the quality of the effluent that is going back into the water table.
PuraMC will serve to reduce the use of potable water at the nature preserve, reuse wastewater and help educate those visiting the nature preserve park how an onsite wastewater treatment system can preserve nature and water.
