Storm Water Pump Station
Project Owner City of Lawrence Project Delivery Method Design-Bid-Build Completion Date / Total Time for Project May 2016 / 6 Months Project Value $2.7 Million

Project Overview

This project consisted of a cast in place concrete pump station 25’ deep below the surface and required dewatering wells to draw groundwater below the construction limits. Completed walls of the pump station are 2.5 feet thick. Due to space limitations, the site could not be open cut and instead a drilled column and wood lagging system was utilized to shore the hole.

The picture of the pump below is one of 4 large pumps with a 20” discharge. Each of these pumps can handle 8,400 gallons per minute. A smaller duty pump rated at 3,000 gallons a minute rests in the middle of the large pumps in a lower sump. 

Bar screens were mounted in front of the pumps that serve to keep large debris out of the pumps to protect from damage.
