- Innovative Solutions Water for 2060 The way to water security:
Just like retirement savings, there are ways to increase the size
of our water nest egg to stretch fresh water reserves in time of
drought and increase future reliability: 1.Spend less conservation,
efficiency, etc. 2.Make more tap into unconventional sources using
marginal quality waters, water reuse, addl. Storage,
regionalization, others 3.Diversify your portfolio multiple water
sources
- Slide 14
- 2012 Update of the OCWP OCWP Studies Potential Options
Generally more statewide in perspective 1.Artificial Recharge
2.Reservoir Viability 3.Marginal Quality Water 4.Conservation-
Efficiency and Reuse

- OCWP Water Conservation Study The OCWP analyzed two general
levels of conservation for each of the two major demand sectors:
1.Moderate 2.Substantial What if Scenarios - M&I: Passive
(Energy Policy Act) vs. high- efficiency plumbing codes/fixtures
Metering: 90% vs. all systems System leakage and losses reduction
Conservation pricing levels Standard educational programs vs.
school curriculum What if Scenarios - Irrigation: Increase
irrigation system efficiency Shift to less water-intensive
crops

- Drought management plans (with specific tier triggers for water
restrictions, including banning all outdoor water use) (e,g OKC,
Duncan, and many others) Emergency water supply plans (e.g., Palo
Alto, CA, Central Lake County, IL) Enforcement of water use
restrictions- Inspectors and Penalties (e.g. OKC) Drought surcharge
on water bills (eg., Pleasanton, CA, Santa Monica, CA) Aggressive
public education and outreach (e.g. statewide) New or existing
emergency interconnects with neighboring water providers (multiple
examples across OK and the west) New wells or water supplies to
augment existing supplies, or aggressively pursuing alternate
supplies (e.g., Mountain Park MCD, OK) New or expanded non-potable
water reuse (e.g., Guymon, OK, and numerous other examples across
the west) Potable water reuse (e.g., Norman, OK, Aurora, CO,
Wichita Falls, TX, Big Spring, TX, Cloudcroft, NM, San Diego, CA)

supplemental appropriation of $1.5 million for drought grants Gov.
Fallin announced availability on Sep. 11 th Focus on responsible
use of water Promote greater water efficiency AND drought
resiliency

- Innovative Solutions Legislative Impact - SB 1187 Encouraged
new rules for reuse & other conservation projects Rulemaking
process underway Several communities focused on conservation
through new practices
- Slide 34
- Create your long-term Plan! including financing Start using
less Today! Implement immediate solutions to preserve existing
supply- e.g. use ordinances, back-up supply contracts, conservation
rate structures, maintain storage. Dont forget your Water Rights!
Obtain and maintain water rights, construct storage, submit annual
use report, avoid stream water right forfeiture Diversify your
Water Portfolio! Reuse or new sources Getting to 2060 Starts and
Ends with Local Planning!
