Georgetown Wet Weather Treatment Station construction update

More activities begin; crews building secant pile

Starting in mid-April 2018, crews will begin building the wall of the facility’s underground Influent Pump Station. Work will include drilling holes about 90 feet into the ground and installing four-foot wide concrete cylinders. The cylinders are called secant piles.

Secant piles lock together to create a structurally stable ring. This ring will be nearly 100 feet wide and is part of the Influent Pump Station’s structural wall.

Secant pile installation is expected to take three to four months.

A video showing what building the secant pile wall might look and sound like is available on our website.

What to expect:

• Work completed weekdays between normal work

   hours, 7 a.m. to 6 p.m.

• Drills, pumps, excavators, cranes and trucks working

    on project site

• Secant piling and excavation activities to continue

   through the summer

• Increased truck traffic in and out of the site

• Increased noise and vibrations near the site

• Hotline staffed 24/7
