BRUNSWICK COUNTY INTERBASIN TRANSFER
2015 ANNUAL REPORT

Due the decreased rainfall levels during the month of July 2015, the average day usage and peak day
potable water usage were slightly higher than in the previous year. However, the total water production
in the month of July at the Northwest Water treatment plant was 18.44 mgd or 76.8% of its permitted
capacity. The potable water usage by customer class was up slightly for the wholesale customers, retail
customers, and industrial customers when compared to 2014. The total interbasin transfer in the month
of July was increased to 9.91 mgd.

Wastewater discharges decreased slightly versus the prior year due to the decreased rainfall. Most of the
wastewater effluent was used as reclaimed water for irrigation of golf courses and tree farms and used
for groundwater recharge.

The interconnection with the Little River Water Company was completed and placed into service. The
County is nearing completions with its Advanced Meter Infrastructure Project which will improve our
ability track flows by basin.
