Recommendations: Actions for Normal and Drought Conditions
In order for sufficient planning to occur, we need to address the possibility
of drought prior to the onset of drought
conditions. While peoples' shower times may be hard to change, the
water pressure supplying their shower can. Furthermore, while the watering
of lawns will probably never stop, the time that lawns are watered can
be changed from daylight to dark. The following recommendations address
actions that should be considered to affect behaviors associated with
water use.
Regulation
- Require a separate section of the WSSMPs for drought.
Drought is a long-term emergency that can be prepared for. Other
emergencies included in the WSSMPs can occur suddenly or unexpectedly.
Therefore, instead of lumping all emergencies together, drought management
should be included in the WSSMPs as a separate section. Drought occurs
often and water suppliers should be preparing for drought everyday.
An adequate WSSMP would reflect this. The separate section should
include the following recommendations.
- All local drought plans should use terminology that is consistent
with SGP 724: The Rhode Island Drought Management Plan.
SGP 724, approved by the Statewide Planning Council in June 2002,
sets forth four levels of drought: advisory, watch, warning and
emergency. All local WSSMPs should utilize this terminology when
discussing drought levels within their system.
- Water suppliers should be responsible for determining drought
levels by measuring the percent capacity of each supply source.
Different locations in the state receive different amounts of rainfall.
While the differences may not be large, they can have significant
impacts on the supply sources in those systems. As we have seen,
most ground water supplied systems are more sensitive to rainfall
than most surface water supplied systems. When drought levels are
based on precipitation, a groundwater supplied system may have received
more precipitation than a surface water supplied system, be in the
same drought phase of a surface water supplied system, yet have
less water in its supply. If a statewide drought level determination
were issued in this case, the groundwater supplied systems would
need more strict water use restrictions than the rest of the state
or face more severe impacts from the drought. Instead, each system
should be responsible for determining its own level of drought,
not based on precipitation, but upon the amount of water in their
supply. Each system can then manage its activities and restrictions
accordingly.
- All water suppliers should outline a schedule for restrictions
on all outdoor water use triggered by percent capacity or supply.
There is not a distinct line between normal conditions and drought
conditions. There should not be. The word "drought" implies
emergency and some systems face water shortages every year. Yet, many
do not. All decisions about water supply demand should be based on
percent capacity, or the amount of water that is available for consumption
to the public. These percent capacity levels should be linked to specific
restrictions to be placed on water use. Water suppliers should be
required to report these restrictions and provide a schedule for said
restrictions in their WSSMP. These restrictions shall increase in
severity as percent capacity of supply decreases. This requirement
should be added into the Rules and Procedures for Water Supply System
Management under the Drought category.
Water Resources Board
- The Rhode Island Water Resources Board shall establish a time frame
for amending the WSSMPs in order to achieve compliance with the State
Drought Plan and other recommendations made here.
Each WSSMP is to be updated and resubmitted to the Water Resources
Board every five years (4).
However, droughts and water supply shortages occur more frequently
than five years in Rhode Island. In order to most effectively plan
for and mitigate drought, these recommended changes to the WSSMPs
need to be in place. The faster they are implemented, the better water
suppliers will fare against drought and other seasonal water shortages.
Therefore, the WRB should acknowledge this and develop a schedule
to which water suppliers can adhere in order to utilize the information
presented in this thesis and the Rhode Island Drought Management Plan
to their advantage. This schedule should include defining drought
levels based on percent capacity, defining consumption reduction goals,
associating these levels and goals with rates and restrictions, and
a methodology for returning back to normal once percent capacity starts
to increase.
