Water Treatment and Distribution

Water Treatment and Distribution

The Town of Gander operates and maintains the community’s water treatment and distribution system, including:

  • Two pump houses
  • One water treatment plant
  • A treated-water reservoir
  • Water mains and related distribution infrastructure

The system supplies drinking water to the Town of Gander and Gander International Airport.

Our Water Source

Gander Lake is the community’s water supply.

The lake is approximately 56 kilometres long and five kilometres wide. It is also one of the deepest lakes in North America, with an estimated depth of approximately 305 metres.

Water is drawn from Gander Lake through an intake pipe located about five metres below the low-water level.

How Water Reaches the Community

Water is pumped from Gander Lake through an approximately 2.7-kilometre aqueduct to the Town’s water treatment plant.

Following treatment, the water is stored in a 6.26-million-litre reservoir before being pumped into the distribution system and delivered to homes, businesses and other properties throughout the community.

Water Treatment

Gander Lake water is naturally soft and acidic, with low alkalinity and low levels of most metals. It also contains naturally occurring organic material that affects colour and treatment requirements.

The Town’s water treatment plant was constructed in 2007 to provide high-quality drinking water to the community.

The treatment process includes:

  • Ozone as the primary disinfectant
  • Soda ash to adjust pH levels
  • A low dose of chloramines to maintain disinfection throughout the distribution system

Water quality is tested daily to help ensure the Town’s drinking water continues to meet applicable standards.

Water Main Flushing

Water mains are flushed twice each year:

  • April to June
  • September to November

Flushing generally takes place between 8:00 a.m. and 4:00 p.m.

This work helps remove sediment from the system and maintain water quality and flow.

What Residents May Notice

During flushing, residents may experience:

  • Temporary changes in water pressure
  • Discoloured water
  • Small amounts of sediment or debris

These conditions are temporary.

If your water appears discoloured after flushing:

  1. Run the cold water until it becomes clear.
  2. Remove and clean faucet aerators if needed.
  3. Check and clean screens in faucets and washing machines.

Residents are encouraged to avoid doing laundry between 7:30 a.m. and 4:00 p.m. while flushing is taking place in their area, as discoloured water may stain clothing.
