This week the construction crews completed the final stages of mortar lining in the tunnel. Mortar lining is one of the final stages of constructing a water tunnel before we bring it into service.
Our workers used specialized equipment that sprays cement on the pipe’s interior to prevent corrosion of the steel pipe and prepare it for water conveyance. This completes a major milestone for the tunnel. The tunnel is anticipated to be in service by the end of this month and will soon deliver water to our 2.6 million customers. We are definitely getting excited for the final stretch!
