Members from Sapphire were recently in Craik to install filter media into the 4 pressurized vessels. 16 ‘totes’ in total was installed over the course of several days. Each tote equating to approximately 1000 pounds.
Further plumbing is presently being worked on to connect the biological filters.
Additionally, some members were initiating the wiring work to connect actuated valves and flow meters.
Monday, November 19th, we will be receiving two large skids that house the nano-filtration components.
While much work remains, it is very encouraging to witness the changes that are occuring on a day to day basis.
Infrastructure work is the focus right now at the water plant.
Several more transformers and electrical junction boxes have been installed. Much of the wiring tray has been installed and some cabling completed.
Further, actuated valves have been installed on the pressurized biological filter tanks and associated plumbing mostly complete.
Presently, contractors are busy starting to load the filter media into the pressurized tanks. At least 2000 kilograms have already been installed with a ‘mere’ 15000 kilograms to go.
We are expecting delivery of the nano-filter membranes shortly. It is a very busy water plant full of concurrent activities all overlapping as we would like them.
The water plant is no stranger to contractors these days.
The concrete pads have been filled and cured. Four pressurized tanks have been installed. One electric motor and vertical turbine pump installed. Variable Frequency Drives (VFDs) have been installed and configured.
Once the second drive is installed, we will slowly ramp up water pressure to the town. The final pressure to be determined at a later date based on user feedback and existing infrastructure limitations.
The biological media has been delivered into the treatment facility and it makes the water plant feel like a very cozy place.
The installation of a third natural gas heater has been completed but is not yet being utilized. Once the new filtration system is operational, it is vital to warm the building to roughly room temperature for the biology to optimally perform.
Presently, work is ongoing with electrical systems, namely transformers, wiring, and control boxes. A new electrical service delivering 600 Volts of power to the facility to be installed by SaskPower at a later date.
A LOT of activity occurred this last week.
All filters to be removed have had their old media removed via vac-truck. Half of the tanks have been removed from the facility and all associated plumbing has been removed.
Also, the intake screen upgrade has been completed.
As is readily apparent, the new screen will help keep silt and organics from entering our wet well. This, in turn, will greatly reduce the demand on our filters by providing cleaner water at the first stage.
The intake screen is also installed several feet higher than the previous one which will reduce the impact stormy weather has traditionally had on our water intake.
A directional drill was brought to the site to install a two inch air line to the new screen. The purpose of the screen is to allow air to be ‘bursted’ up through the screen to blow out any sediment that may have collected on it over time.
In total, this upgrade will have almost immediate impact on our ability to produce aesthetic water.
Cleaning of the wet well is expected to be completed on Saturday 15, 2018.
Four pressurized vessels were received this week. In addition, two electrical motors, one natural gas, and three vertical turbine pumps came to our community.
Presently, 4 of 5 sand filters have been taken offline and are being prepped for removal.
Half of the current Mainstream system is to be taken offline September 11 in conjunction with the intake screen upgrade project happening at the Craik Dam.
At present, water reserves are in excellent shape with an additional 40 thousand gallons for fire purposes.
While the intake project continues, the community will not be drawing fresh water from the dam for up to 2 days. Service to the community will not experience any disruptions during this process.
Aside from the additional backup fire reserves, we have over three days of water capacity presently treated and no precautions are necessary for the community.
As a reminder, it is requested that the public avoid visiting areas where work is being performed.
The job sites involve heavy equipment, enclosed spaces, excavation, and other hazards. We will do our best to document progress via pictures and continual updates.
