South Reservoirs before construction
In 2019 Mt. View-Edgewood Water Company is constructing a 1 Million Gallon concrete reservoir.
A house next to the existing reservoirs was demolished to make room for the new reservoir.
Storm water piping has been installed to manage storm water runoff from the reservoir site.
A very large boulder was found during the excavation for the reservoir foundation area. It will be incorporated into the landscaping.
As of 5/28/19 the reservoir site has been excavated, base rock has been placed and compacted, and some underground utility installation is complete.
On June 14 the concrete foundation and slab for the reservoir was poured. The 12 recesses in the slab you see are for the concrete columns that will support the roof.
The contractor poured the concrete for the first section of wall on 7/19/19. The contractor will pour five more sections over the next two weeks in July.
Contractor poured the second wall section on Wednesday July 24.
Contractor poured the third wall section on July 26.
Contractor poured the fourth wall section on July 30 and fifth wall section on August 1.
Between August 2nd and August 9th 11 columns and footings were poured.
The last wall section and last column footing were poured on August 15th. The last column was poured on August 16th.
Wall forms removed and reservoir with all the walls as of 8/23/19.
Interior steel piping for inlet, outlet, and overflow was installed in late August.
Scaffolding and shoring installed in late August for roof placement.
Forms for roof constructed in early September. Rebar installation began 9/09/19. Tendons were stressed on 9/6/19 and filled on 9/9/19.
The concrete roof was poured on September 23, 2019. Curing the roof and then removing the shoring will take several weeks.
On 10/24 and 10/25 exterior wall was pressure washed to prepare wall for shotcreting.
Check out this video of the DN Tanks shotcreting the exterior of the reservoir on 10/28/19.
Contractor completed the shotcreting of the exterior walls on 11/14/19.
After the first layer of shotcrete was placed, seven-wire strand was wrapped around the reservoir on 11/1/19 and 11/4/19.
DN Tanks started with placing covering shotcrete layers on 11/06/19
Following the placement of the shotcrete, the walls were wrapped in plastic for water curing of the concrete on 11/15/19.
The roof access ladder was installed on 11/15/19. The bottom is currently not attached because a couple feet of fill and a concrete pad will be installed later.

In January and February electrical conduits and wires were installed between the electrical controls in the existing booster pump station to pumps, meters, valves, and sensors.
On January 28, 2020 the reservoir interior was cleaned in preparation for filling and leak test. The leak test failed.
Following the failure of the first leak test the contractor patched all noticeable interior cracks and injected epoxy around the outlet and drain piping. The reservoir was cleaned again on 2/18/20 and filled. Reservoir passed leak test on 2/27/20.
Painting of the reservoir to match the color of the existing reservoirs on-site began on 2/20/20.
