A huge opportunity has opened its self up. The city has agreed to postpone a portion of the Development cost that would upgrade the water main supply from 13mm to 19mm. Typically projects like this are required to upgrade the water service because of additional fixtures. What we will attempt to prove is that the rainwater collection systems we have planned, combined with the single occupant of the house will mean minimal increase in water usage for the new building. This opportunity does NOT mean that we have avoided paying the development charges. What it means is that they have allowed us to delay the expense of the water supply upgrade until renovations/additions are carried out on the existing house. We should also point out that this opportunity is a one off and we expect that this generous exception will not happen again.
So the rain water system is looking promising once more. We are considering a redesign of the storage tanks right now and may opt for builtin concrete tank, instead of food grade plastic tanks. But the system as planned will be collecting rain water into a 9m3 tank (2500 gallons). This will be cleaned and filtered to near potable standards (including but not limited to 5 micron filter + UV + Black Carbon filter) before it is distributed to the Laundry, toilet (should we need it), and outside irrigation system. There is some debate about using this light grey water is appropriate in the dish washer.
The City will require their water to feed the kitchen sink, bathroom sink. Laundry sink and shower.
Looking forward to seeing how this project will develop.
A productive visit with staff at Cascadia offices in both Portland and Seattle early January. A long discussion about material supply chains and the Materials petal. The major push is to ensure that we are using FSC lumber up here. This is interesting because to date projects in BC, Canada have not used 100% FSC. Exceptions have been made for “Pine Beetle Kill that would have been Clear cut anyway.” At the SFU childcare Centre Kourosh Mahvash came up with a fascinating solution that basically involved purchasing a forest and processing the beetle kill wood with the help of a local mill.
Returning to Kelowna we connected with the Manager for Forest and Environment at Tolko, one of the local mills. Turns out we connected to the person that had procured Pine Beetle Kill Wood for the building in Penticton. Further discussion around sustainability and certification outlined for us the complexities of wood supply in BC and Canada. This aspect of the LBC has many facets and angles to be considered.
At this point our strategy is to connect to Local wood, cut by Local people, milled at plants 120 km from Kelowna. Long discussion and consideration was given to using all FSC lumber. It is not making sense both ethically and financially to drive across the boarder to the US to purchase lumber and plywood. Let us hope that the LBC review board sees it the way we do.
