Agenda
1. Welcome – Mayor Milne2. Introduction/Background 3. Outline of Plan, summary of public input4. Conservation and Efficiency measures, Q&A 5. Alternative Water Sources, Q&A6. District of Sechelt potential actions (regulatory,
incentives, parks) Q&A7. Wrap up – Mayor Bruce Milne
3
What is a Water Conservation Plan?
A plan containing policies and actions aimed at;
Reducing potable water use or,
Making better use of water
4
Why do we need a Water Conservation Plan?
1. Provincial requirement 2. OCP says so3. Sustainability Plan says so4. Helps avoid/delay/cope with
droughts or water restrictions
5
Why do we need a Water Conservation Plan?
“When the well’s dry, we know the worth of water”
Benjamin Franklin, 1746
6
“Okotoks, Alberta Water Conservation Plan
play Okotoks video
Actions Regulatory tools (bylaws, density bonusing,
etc) Metering, conservation rates Fixture replacement program Water audits Alternative water sources Education Maintaining the focus
7
“Drought Response” is different from “Planned” Water
Conservation
Drought response are things we are forced to do, and/or would not otherwise do.
Planned measures are things that we plan to do, whether we are in a drought or not
drought responses are (usually) temporary, planned measures are (usually) permanent.
8
Example – garden water use
Drought Response Planned Measures
Let lawn go brown Let lawn go brownLess lawn area
Let the tomatoes go brown Drip irrigation of tomatoes
Bucketing water from bath onto garden
Alternate water system (rain, grey, reclaimed, etc)
The primary focus of this Plan is on “Planned” measures
9
Four main ways to reduce potable water use.
Conservation – to do less of something or reduce waste
Efficiency – to use less water for the same purpose/production
Productivity- to increase production for the same water
Alternative Source – use a non-potable water source instead

Alternative Water Sources
Any source of water other than SCRD potable water
Generally meaning non-potable water, for non-potable purposes
Alternative sources are not subject to SCRD water Restrictions
San Ramon video
22
Rules for Non-Potable water
Don’t use it for drinking Specific plumbing code rules, permit
required No cross-connection to potable system allowed Water quality guidelines for for toilet flushing. Specific (and developing) rules and guidelines
about outdoor greywater use Specific rules about use of reclaimed water Cannot supply a neighbour
24
Rainwater
Defined as rain water collected from a roof
Needs to be stored in a Dark Place No treatment required for outdoor use Indoor use subject to plumbing code rules Roof material will affect quantity and
quality of water Large storage volume required to get
through long dry summers
26
Stormwater
Defined as rain water collected from roads, parking lots, playing fields
Can be used for “roadside Water Gardens” Potential for Street Tree watering Encourage infiltration to ground, where
possible. No private residential use allowed.
28
Greywater
Defined as untreated water from bath, shower or laundry.
Kitchen and toilet water are black water Needs to be used, not stored Indoor use subject to plumbing code rules
and quality requirements Developing rules for outdoor use. Simplest approach is for diversion to
subsurface irrigation
29
Groundwater
Defined as water from a well No provincial restrictions on single-house
residential groundwater wells Quality is variable If house is connected to SCRD water,
groundwater is considered as “non-potable” water and subject to plumbing code rules
No restrictions for outdoor use.
31
Reclaimed Water
Water from the Sechelt Water Resource Centre
Considered “non-potable” water Rules and restrictions for all use. Users must register first Area specific for piped service Potential for service to residential areas in
downtown Sechelt Consideration of public and commercial
filling stations

DoS Specific Actions (1)
Complete a Water Conservation Plan Update bylaws for water efficiency Co-operation with SCRD on water Compile all relevant information for
homeowners on water conservation and efficiency
Rainwater Harvesting Guide Facilitate a Sechelt Waterwise Gardening
guide
35
DoS Specific Actions (2)
Compile all relevant information, rules etc on alternate water sources
Look for more ways to use stormwater for streetscapes
Public non-potable filling station Reclaimed water system Reclaimed water for DoS Parks Metered wastewater rates Consideration of financial incentives
Any others?
