The City of Terrace Community Water System serves a population of approximately 12,000 people with 3,943 water connections. There are three sources of water that the system draws from:

• Frank St. Wells
• Deep Creek
• Skeena River

The Frank St. Wells provide over 99% of the water delivered to end users, with Deep Creek and the Skeena River serving as emergency backup sources. Storage is provided at two reservoir sites:

• Wilson St. reservoirs: Two reservoirs that service most of the community and Brauns Island
  • Combined volume of the two reservoirs is 2,712m³ with a maximum winter turnover rate of 30 hours
• Halliwell reservoir: Services the Bench neighbourhoods and some areas of the Regional District to the north of town
  • The largest of the three reservoirs, with a volume of 2,727m³ and a maximum winter turnover of 48 hours
