Serenity Garden Posting - #12 West Cafe Patio Water Feature by Dan Smith
This tab describes a large water feature that also includes a donor recognition space.
#12 West Cafe Patio Water Feature. This feature measures 10' W x 2' D x 8' H and is a focal point of the West Cafe Patio Arbor. Constructed of concrete and steel and lit from the overhead arbor, the water feature will be positioned along the wall at the north end of the patio." [More Meaningful Moments, page 6 - 7 & 10]
Recent Photo of feature under construction are as follows

The following material is for reference only.
Figure 1 is a concept diagram showing the key elements of #12. Note that the concept design also includes an extension of the water feature described above. The dimensions are more than stated above. The extension allows part of the stone wall to be used for donor recognition surfaces.

Key to Figure 1.
(1) Water Feature of stacked stone with water cascading down and splashing gently off the stacked stone.
(2) Cascading water flowing over stone to the basin at bottom. This water flows along the crevices and from the right to the left dripping gently and splashing in some places into the basins.
(3) Basins that collect water. The water flows to the left in the picture toward the cafe door and then returns to (2). The basin will intrude onto the surface 2-3 feet at location (2) where it continues to cascade. The basin will be staggered in and out up to 4 feet. The basin will consist of water plants as well as soil-based plants.
(4) Garden donor recognition wall. This is a stacked stone "shelving" structure like (1) that is the back of the basin and comes up from the basin and connects to the water feature. It extends from the Water Feature stacked stone (1) back toward the cafe entrance. Various heights and depths will provide shelves for donor recognition, currently envisioned to be engraved or laser cut stone, metal, or other affixed to the stone shelving.
(5) The existing building elements. The emergency oxygen green box needs to be researched to be sure it continues to serve its purpose. No change will be made to any of these three existing features other than lessening their visual impact but retaining the required access/functions. The aluminum vent can be painted out the color of the brick.

Figure 4 below is similar to Figure 1. This shows the dimensions up the brick wall and pushing out onto the concrete patio. This layout is currently (8/24/17) at HODC to observe.

Figure 5 below shows the layout plan for the fountain. The wall portion shown in brown is about 8 in thick. That layer appears as stacked stone shelves projecting irregularly out as as shown in Figure 2 and 3 illustrations. This detail to be worked out as part of the stone selection and the installer. The blue pools A and B are the collection basins for the water flowing off the stone wall from higher up the wall at C. Water flows down and drips off the wall into basin A and B like a natural dripping mountain wall and returns to C. The ends of the basins include a planter basin D and E. The retaining wall of the basins are 18 inches high from the patio surface and capped with a stone ledge. The face stone for the retaining wall may be similar to the stone in the patio columns, Figure 1. The top of the walls may be flagstone like used to cap the column supports on the patio, Figure 1.

Note the incorporation of accent boulders. The contractor will work with Consilium and HODC to work out the details as part of the installation
9/19/17 Questions posed and responses in red by water feature contractor.
1. It seems the best thing for the electricity connect, is for the contractor to lay out the project and identify where the pump cord should go through the patio brick wall and into the adjacent mechanical room. Then the electrician can add the outlet connection. The outlet could be inside the building or could be mounted outside. We can figure that out early on the site as you proceed. I see no reason why it can't be outside, as long as it is a GFCI receptacle with cover for weather. Dan and contractor to decide when the project begins.
2. When the time comes to "stack" the stone, I want to review that with you at the time to ensure the effect is what I have in mind. I consider this a functioning work of art and want it to come out like I am imaging it looking and performing. I think it would be a good idea to mock up part of the wall as you start just as loose (no mortar) stone. And get a buy off on it before you lays it all down and lock it down. I'd like Hospice to see it also and get their buy off before it all goes into place. That no problem...We have to get the base and the wall finished prior to any stacking of the stones. Also,, running the plumbing...
3. Can you pencil in a start date for this project? 9/19/17 I have a water feature rebuild I'm doing now and start another one next week 9/26/17. Also, scheduled to put in a 32 foot waterfall on a swimming pool. That will depend on when they finish the pool. I will have to get an idea on when they finish the pool first or when they will need me. Contract for that one has already been signed. {no date set as of 9/25/17.. best guess is sometime in October OPEN}
4. How long will it take to construct? Minimum week.
5. Where will the pump be located? It has to be within 15' of power. So that makes it in the right lower basin of the feature. Is that correct? Pump will be in down inside the basin with filter around it.
6. (see 1 above also) Will you bore a hole through the brick exterior wall that allows the power cord for the pump (its plug in tact) pass through the wall? I will have to check again on the location of a plug inside that mechanical room and/or if we need to add one. Have Electrician run wire through mortar joint and install box outside on wall some on the right side away from the feature. Will determine location when contractor begins work.
7. If the pump is far right, will it draw water from the far left so that the basin water circulates? We can add a large pump that will circulate the falls and additional locations. Its going to pull all of the water over time.
8. Will it then pump the water up into the water wall via a PVC pipe to a "basin" at the upper level where it then exits from several outlets to various points on the water wall? Mostly the question is how does the water find its way along the water wall for its length? PVC Pipe with holes / slits in it. Control by ball valves...
9. If for instance there is a basin at the top (hidden) then that would allow water to be controlled from its outlets. The point of this item is how can we "adjust" the flow to parts of the water wall so as to adjust/tune it? Adjustments can be made from within the basin Space is limited.
10. Does the pump have a cut off if the water goes to low? Normally they are thermally protected if they heat up too much. Will shut off...
11. If the UV light is added, where would it go and where would it be plugged in? Cord length, etc. 15 foot cord, submersible UV light down in the basin.
UV light will reduce some bacteria, including harmful bacteria, as well as microscopic organisms and will also destroy the DNA in single cell algae cells thereby killing it very efficiently and help keep water clear.
Note: pump + UV light + possible LED lights = 3 outlet need. [OPEN]
12. I presume the UV light could be added in the future? Yes
13. What would the UV light cost? It's benefits in our case/effectivity. Around $250.00
14. I am thinking for safety that the basin would either have shallow water so some kid does not fall in and drown, or would have a grid just under the water, say three inches. I have seen these. Anything that falls in that can't go through the grid would be OK. Plants in pots can be on that grid also. Leaves etc, even coins (yuk) would fall through, thus deterring coins. We can see what it look likes once completed for this option.
11. Will the liner be installed in a way that makes it easy to remove and replace when the time comes? Has a 20 year manufacturers warranty. Shouldn't need replacing at all.
12. I have suggested LED lighting for the wall/feature. What are your thoughts on this. We can add those after it is completed. I will make sure there are access through the basin to run the wires. There are still a few things I have to think about before construction. I can spend time getting all of the materials together and having a more definite plan... It will all work out.
Note: pump + UV light + possible LED lights = 3 outlet need. [OPEN]
