Infrastructure connectivity for communities is critical. As piping assets age, there is an increased risk of gas release and reduced reliability in the system. That is why NPL Canada, their crew of 11, and Indigenous peoples came together in spring of 2023 to upgrade the infrastructure on behalf of the local community.

In 2019, an annual water survey identified three locations crossing East Sixteen Mile Creek in Milton, Ontario with low or no cover on a customer’s 12” and 8” pipelines. Additional watercourse crossing assessments further revealed the need for mitigation measures. Based on the findings, the NPL Canada team replaced and redirected the 12” pipeline beneath the watercourse using Horizontal Directional Drilling.

The work, completed over the course of five months was often in exposed, open fields. To ensure the protection of wildlife, the team put in place measures to effectively mitigate the impact of the work including daily environmental sweeps with the client and water mitigation pumping to keep contaminants from reaching water resources in the surrounding areas. Furthermore, and as part of NPL Canada’s commitment to working together with Indigenous groups, Indigenous liaisons were on site including partners from Three Fires Group ( to provide oversight, and proper acknowledgment and protection of the land being affected. The job was completed on budget and ahead of schedule.
