Operator training underway on the new ozone system
Water Treatment Plant Construction Update
On Thursday, the third and final crane that was used for construction was dismantled and removed off-site. As construction comes to a close, more equipment and materials will be leaving the site.
In mid-April, crews expect to remove the large construction trailers currently located on the western corner of the site. Removal is expected to take about a week. A small trailer will be present for the remaining work, near where the carpenters' shed was located on the west side of the site.
WTP staff have been undertaking intense training for the new ozone system. The system is undergoing startup and testing through the next month. The photo herein shows the inside of one of the two ozone generators. The generator uses electrical energy to transform oxygen into ozone for the water treatment process. By early May, the ozone system is expected to be fully operational. This marks the final change in the water treatment process at the plant.
Elsewhere on the site, civil crews continue working on sidewalks, curbs, gutters, catch basins, site walls, stone walls, light pole bases and miscellaneous piping.
Miscellaneous demolition work – early April
On Monday, April 3, crews will begin removing the temporary carpenters' shed (near the construction trailers) and the west side wheel wash. On Monday, crews will need to use an excavator with a hammer attachment to break up the concrete slabs that were installed for these structures. Neighbors may notice an increase in intermittent noise and possible vibration while the hammer is in use. This activity is expected to take one day to complete. Thank you to neighbors for your patience during this work.
Other activities occurring in April
Through April, crews expect to be forming and pouring curbs, gutters and catch basins; installing site irrigation; forming the pedestrian pathway; installing pervious pavers; grading the site; and paving asphalt areas (weather dependent).
