- “relatively low cost practical solution to the water quantity and quality problems along Senanus drive may be feasible…” “where there is the ability and willingness to cooperate on a logical basis.”
- “The water can be treated with point-of-entry or point-of-use treatment device to meet the AO or the GCDWQ.”
- “effects of these [palatability parameters] can be readily counter-acted by in-home treatment systems”
- “The most common water treatment technology used in BC is ion exchange for water softening (reducing hardness). These units range in capacity, and costs depend on a number of parameters, such as volume treated per day and TDS of the input waters."
- “Many homes in BC have water treatment systems for in-house use only, and use a combination of untreated well water and collected rainwater for garden irrigation. These ion exchange systems typically cost between $500 and $4000 to install and a few hundred dollars a year to operate. This assumes that a 5 to 7 gpm capacity ion exchange system is installed, along with a rainwater tank and small pump.”
Piteau Report,2001
- “If a detailed hydrogeological assessment was carried out it may be possible to develop a local area groundwater management strategy that would minimize the water quality problem in the area.”
- “Management options could include: setting abstraction limits on selected wells, promoting groundwater recharge, encouraging the use of cisterns for storing roof runoff, grouting off fractures in selected wells, abandoning some of the wells near the shoreline and possibly installing a community well field further inland.”
- "Practical ways of promoting groundwater recharge include: inserting check dams in road side and driveway ditches, installing perforated storm drains, installing soak-a-way pits for roof drainage and installing leaky stormwater retention ponds. These recharge facilities need not necessarily be located in the study area. For example, it may be shown that collecting and infiltrating storm water along West Saanich Road is viable and useful way of increasing the flow of groundwater under the study area.”
- “Draft Groundwater legislation has included provision for the establishment of groundwater management areas in British Columbia. If a suitable legal framework was established and the local water users were willing to cooperate, a relatively low cost and practical solution to the water quality and quantity problems along Senanus Drive may be feasible.
- Rainwater collection potential, calculated using the area measure tool of the CRD Natural Areas GIS data for the roof areas shown at the 21 Senanus properties, is 9,687,005.7 Litres of water per year. According to environment Canada rates of 329 Litres per person per day, this would serve 80.66 people, for one year. This is in addition to all other water sources. According to a Senanus resident,
"Many of the homes on Senanus Drive are "modest," many have only 1 resident, others 2, and some are occupied during the summer and believe it or not many have low flush toilets and showerheads."
If the above statement was true for the 21 properties on Senanus, then there are, according to the letter writer, about 40 people living on Senanus. If this was the case, it would mean that rainwater alone - if it was being used - would be sufficient for Senanus Drive residents to have double the Environment Canada daily water allowance per capita, assuming daily per capita usage of 329 litres per day. The rainwater could be used for aquifer recharge, irrigation, or non-potable water requirements, while potable groundwater used for human consumption.
