A little extra rock is being used to shore up the foundation of the Sunnyside Port District's new Sequencing Batch Reactor (SBR) construction project on Midvale Road. .
SBR contractors recently encountered high groundwater conditions while excavating the SBR construction site, according to Port officials.
"We knew we would be encountering shallow groundwater conditions on the project," said Port Manager Amber Hansen.
Hansen said most of the Port's spray fields surrounding its industrial wastewater treatment plant have high groundwater levels.
"We just need to 'over-excavate' the site and add more rock to stabilize the foundations for the reactor," Hansen explained.
She said the costs for the possibility of the groundwater conditions was factored in when the Port called for bids on the project, which is expected to cost $5.7 million.
In a related SBR construction issue, the Sunnyside Port Commission will meet for a special meeting tomorrow (Thursday) at noon at the Port office, to sign agreement for burrowing under the railroad crossing near the project.
The commissioners are expected to sign a $1,500 warrant to fund the permit filing, Hansen explained.
She said the commissioners will also meet in executive session to discuss legal issues surrounding a land purchase.
