MESA Tank Replacement Project

The City of Santa Paula's Mesa Tanks Replacement project has begun. This project will take place at the location of the existing tanks on the City Parcel. This project involves the construction of two 300,000-gallon tanks, above-ground welded steel tanks, appurtenances, and a retaining wall. This project is intended to replace aging water infrastructure and improve the water system's reliability that serves our residents and the community. 

The construction will be performed by Canyon Springs Enterprises, Inc. and is anticipated to take approximately 18 months.

Project Updates

2/20/2024
The new tank is going to be filled with water and testing performed starting the week of 2/20.  The final piping for that tank is being installed and it will be connected to the existing water pipeline in a process the week of the 26th.  At that point, the new tank will be in service assuming all of the tests pass.  Work will then commence on the western tank replacement.  Demolition of that tank will take a couple of weeks.  Electrical work at the site is being installed in preparation for the new tank to come online.

1/16/2024
The tank internal coating is complete and the external coating process has been halted due to the cold temperatures and wet weather.  The underground piping and electrical work will be occurring over several weeks.  It is planned that the eastern tank will be complete mid February 2024 and work on the remaining (western) tank will start in March.

10/10/23
Work at the site has started to focus on the construction of the eastern replacement Mesa tank.  That work will occur over several months.  The metal for the eastern tank has been completed at the manufacturing facility and will be shipped to the site over the next couple of weeks as the tank erection crew needs it. The tank shell and roof will be completed in approximately 5 weeks.

10/01/23

09/26/23
The retaining wall construction/placement is complete at the project site.  Work at the site has started to focus on the construction of the eastern replacement Mesa tank.  That work will occur over several months.  The metal for the eastern tank has been completed at the manufacturing facility and will be shipped to the site in a couple of weeks.

08/21/23
The retaining wall construction/placement is complete at the project site.  The waterproofing product application was completed last week and later this week, depending on the site accessibility, the Contractor will continue to perform the backfilling of the retaining wall.  After that, work at the site will start to focus on the construction of the eastern replacement Mesa tank.  That work will occur over several months.  The metal for the eastern tank is to be fabricated starting next week at the manufacturer’s facility and will take 3 weeks.

07/03/23
Based on the current schedule, the retaining wall construction is underway.  The Contractor completed the installation of the shoring.  The retaining wall construction is currently being performed.  Concrete for the retaining wall footing is scheduled to occur on 7/5.  That work will take about a month, and then work on the replacement east tank foundation will begin.

06/21/23
Based on the current schedule, initial retaining wall grading at the site is occurring.  The Contractor completed the installation of the shoring for the future retaining wall construction.  The retaining wall construction is set to start on Monday.  That work will take about a month, and then work on the replacement east tank foundation and support soil will begin.

06/13/23
Based on the current schedule, initial retaining wall grading at the site is occurring.  The Contractor is in the process of completing the installation of the shoring for the future retaining wall construction.  The retaining wall work is set to begin at the project site in approximately one week.  That work will take about a month, and then work on the replacement east tank foundation and support soil will begin.

05/22/23
The waterline work associated with the tank improvements is complete.  Based on the current schedule, initial retaining wall grading at the site is occurring. This will allow the contractor to mobilize the drilling contractor this week to the site to install the shoring system for the proposed retaining wall construction. The retaining wall work is set to begin at the project site in approximately two weeks.  That work will take about a month, and then work on the replacement east tank foundation and support soil will begin. 

05/10/23
The waterline work associated with the tank improvements is complete.  Based on the current schedule, initial retaining wall grading at the site is occurring. This will allow the contractor to mobilize the drilling contractor to the site to install the shoring system for the proposed retaining wall construction.  The retaining wall work is set to begin at the project site in approximately two weeks.  That work will take about a month, and then work on the replacement east tank foundation and support soil will begin. 

04/25/23
The waterline work associated with the tank improvements is nearing completion.  Based on the current schedule and some remedial grading at the site that will occur next week, the retaining wall work is set to begin at the project site in approximately two weeks.  That work will take about a month, and then work on the replacement east tank foundation and support soil will begin.

04/17/23
The waterline work associated with the tank improvements is nearing completion.  Based on the current schedule and some remedial grading at the site that will occur next week, the retaining wall work is set to begin at the project site in approximately two weeks.  That work will take about a month, and then work on the replacement east tank foundation and support soil will begin.

04/10/23
Work is continuing on the waterline installation on Montclair Drive/Place near the tank site.  As the site dries out from the considerable rain amount, work will commence on the retaining wall work that is to be installed north of the proposed tank locations.  The retaining wall work is likely to start in approximately 3 weeks.

04/5/23
Mesa Tanks replacement progress has been focused on the waterline installation that is required east of the tank site to connect to the distribution system to increase reliability.  The rain has prevented work on the retaining wall for the new tank site.  Waterline work is expected to continue for the next couple of weeks. After that, work will begin on the construction of the first replacement tank as the site dries out and work can proceed safely.  

03/27/23
Mesa Tank's progress has been focused on the waterline installation.  The rain has prevented work on the retaining wall for the new tank site. Waterline work is expected to continue for the next couple of weeks.  After that, work will begin on the construction of the first replacement tank.

03/14/23
The Mesa Tanks Replacement project has removed the east water tank, and work is underway installing the new 8-inch diameter waterline that connects the tank site to the existing waterline to the east.  Work has been hampered by the rain events, but it is anticipated that later this week and into next week, the water line work will continue when no rain is present.   That work will continue for a couple of weeks.  After that, the retaining wall work at the north side of the site will start and continue for approximately 5 weeks.  After that, the replacement tank work will start at the site.

03/6/23
The eastern tank was removed from the site.  The work focuses on the 8-inch diameter water line to be installed in Montclair Place to connect the new tanks to the existing distribution pipeline east of the tank site.  Later this week, the retaining wall subcontractor will arrive and begin setting up their equipment to start the retaining wall layout and construction.  That work will continue for several weeks.  Once the retaining wall work is completed, work will start on the preparation for the installation of the replacement water tank.  That work will extend for several months

02/27/23
The eastern tank has been completely removed from the site.  Work will resume after the rain subsides later this week, depending on the soil conditions.  Later this week and early next, the retaining wall work will start at the site now that the eastern tank has been removed.  Also, waterline work will be started next week, installing a replacement waterline in Montclair Place to reconnect to the water line on Vista Grande.
