Project Description	Additional Water Savings	Cost Parameters (1998 dollars)	Project Timing and Life	Environmental Issues	Conclusions and Other Comments *
Conservation:
MPWMD ordinances, incentive programs, water credit program, and educational efforts	Study planned in 1999 to assess potential future savings; about 1,800-af savings from 1987 level documented to date. Cal-Am users have low consumption rates.	MPWMD toilet rebate program totals $545,000 per year in FY 1998-99. Toilet replacement refund program cost is $353,000 for 85-af savings, to date; 500-af additional savings estimated to cost $3.8 million (capital) plus $192,000 per year to administer program and maintain savings achieved.	Ongoing since 1987. Residential credit program sunset 9/30/98 and is being reconsidered.	Helps "stretch" existing supply and reduce per capita consumption. Helps reduce diversion impact on Carmel River. Possible effect on sewage transmission if flow volumes reduced; disposal of old toilets.	Feasible. Substantively implemented at present; study planned to assess program and potential for future savings; 500-af potential conservation savings assumed (see text).
Cal-Am leak detection program and changes in rate structure	Possible 80 af/yr cited by Cal-Am for leak program.	$1.5 million per year cited for accelerated water main replacement program.	Ongoing main replacement program.	Minimal	CPUC in 1998 denied, without prejudice, Cal-Am’s accelerated water main replacement program.
Military (and other government) retrofit programs	Extensive retrofit has already occurred at military bases; there is limited future potential. Higher student enrollment has outweighed savings at Presidio.	No information about military costs. Study estimated 6.88 af saved (1.03 af with credit) for $48,800 retrofit of public schools in Pacific Grove.	Extensive retrofitting already completed; efforts continue.	Disposal of old toilets	Feasible. Substantively implemented at present; limited potential for future savings. Other factors such as student enrollment can outweigh savings from retrofits.
Local water marketing	Unknown; entails variable quarterly limits.	Unknown. Would entail extensive database and customer service staff.	If implemented, would be permanent.	Minimal.	Not a means for permanent conservation as water use would vary quarterly.
Permanent mandatory rationing	15% reduction from existing allocation of 17,641 af needed to comply with interim SWRCB production goal.	$600,000 per year for MPWMD rationing program in 1989-1991 (20% reduction goal).	Standby conservation and rationing plan anticipated in fall 1998; permanent plan envisioned.	Socioeconomic impacts on residents and business.	Not deemed acceptable by CPUC.
Reclamation:
CAWD/PBCSD Project. Designed for 800-af/yr reclaimed water for golf course irrigation in Pebble Beach	Current net savings is 420 af/yr (380 af/yr to project sponsor). Possible 85- to 100-af savings for Pacific Grove extension.	Initial project capital cost was $34 million; $6-8 million for improvements to Forest Lake Reservoir to improve reliability; $1.95 million capital and $35,000 O&M for extension to Pacific Grove.	In operation since 1994. Pacific Grove extension lacks sponsors presently.	Helps reduce diversions from Carmel River. Site-specific facility impacts. Health concerns if human contact.	Presently implemented. Pacific Grove extension is viable, assuming funding issues are resolved; 85 af of savings appears feasible.
MRWPCA regional project	215-af/yr potential for turf and open space in Cal-Am system (187 af for Del Monte golf course alone).	Costs would be shared by participating agencies (total of $9-37 million for capital, $300,000 to $1.2 million per year for O&M in 1996 dollars); share for 215 af/yr in Cal-Am system estimated at $3.8 million capital, $76,000 per year (in 1998 dollars).	No plan for implementation presently; requires agency and receptor cooperation.	Helps reduce diversions from Carmel River. Site-specific facility impacts. Health concerns if human contact.	215 af appears reasonable if reclaimed water cost is competitive with Cal-Am water prices or if government subsidizes use of more costly reclaimed water.
Sewer Carmel Valley and apply reclaimed water on golf courses	Roughly 950 af	$94 million for treatment plant	No plan for implementation presently.	Would reduce inflow to Carmel River by about 660 af (e.g., loss of recharge by septic systems). Health Department has strict control on application rates in Carmel Valley.	Not reasonably foreseeable due to river impact and health concerns, as well as very high cost.
Require use of reclaimed water on all golf courses; recharge aquifers with reclaimed water	Nearly all golf courses in Cal-Am system are presently on reclaimed water. Very limited potential for recharge or use on Carmel Valley courses because of Health Department restrictions.	See Pebble Beach and MCWRA information above.	Existing project serves most Cal-Am courses.	Health Department has strict controls for use of reclaimed water for non-Cal-Am courses in Carmel Valley and is concerned about contamination of aquifer via recharge.	Not a viable means to legalize Cal-Am supply except for 187 af at Del Monte golf course (see MRWPCA above).
Subpotable supplies for turf and landscape irrigation	Several projects already implemented.	Minimal data available. Lake El Estero project cost $37,255 for program with net 1.98 af/yr savings. City of Monterey has $87,000 study in progress reviewing subpotable sources.	Unknown. Each project would take 1-2 years to implement.	Helps reduce use of drinking water and impacts of river diversions.	Presently being implemented or pursued. Nominal additional savings expected.
Stormwater reuse	Significant quantities of stormwater are produced. Limiting factors are storage, treatment, transmission facilities, and receptors.	No information available for specific project.	Unknown at this time.	Helps reduce impacts of river diversions and runoff into the ocean. Must remove toxic chemicals before suitable for use for supply.	Not reasonably foreseeable as supply for Cal-Am system due to storage, treatment, receptor constraints (reclaimed water may already serve primary receptors).

* "Feasible" means project is a reasonably foreseeable means to provide lawful supply for Cal-Am water system or reduce community demand to help facilitate compliance with SWRCB order. See text for further discussion.
