The problem

A municipal water main in British Columbia needed a new impressed current anode bed before winter.

The existing rectifier sat in the path of the new route, the trench window was two days, and the owner wanted proof of protection at every test point, not a sample.

Our approach

  1. 01

    Quote and award

    Fixed-scope quote with terms and insurance linked; award accepted in the client portal.

  2. 02

    Mobilize

    Readiness checklist closed, materials shipped, two-person crew from Calgary.

  3. 03

    Install

    200 ft of linear MMO anode. Wall thickness 7.9 mm at the connection; a redundant connection approved on site as CO-01.

  4. 04

    Commission

    Rectifier relocated and energized on 11 Dec. All six test points read past −850 mV.

  5. 05

    Turn over

    Turnover package issued the next day and the release e-signed in the portal.
