Rincon is comprised of a parent district, which is divided into five geographic divisions. The voters within

these divisions elect a fivemember Board of Directors, each of whom serves a (staggered) fouryear term

The Board of Directors oversees the District through an appointed General Manager of 19 fulltime

employees.

approximately 27,000 acres (42 square miles), potable and recycled water are served through its two

In order to project how the Districts water demands will transition from current demand to projected

demands (up to 2030), the District utilized population projections from the San Diego Association of

BaselinesandTargets

In February of 2008, Governor Schwarzenegger introduced a comprehensive plan for the SacramentoSan

Joaquin Delta. One of the key elements of this program was to achieve a 20% reduction in statewide per

capita

use

by

the

year

2020.

This

lead

to

Department

of

Water

Resources

(DWR)

and

the

State

WateResourcesControlBoardtodevelopthe20X2020WaterConservationPlaninFebruary2010.

InNovember2010,theWaterConservationActof2009(SBx77)wassignedintolaw,addressingagricultura

and urban water conservation, and supporting the 20X2020 Plan by providing guidance and requiring

implementation of baseline and compliance water use. This legislation called for the development of

methodologiesandassociatedcriteriafortheRetailerSuppliertodetermineitscompliance. ThoseStrategies

include:

Methodology1:GrossWaterUse

(CDP).

The CDP is a fullypermitted seawater desalination plant and conveyance pipeline. Located at the Encina

Power Station in Carlsbad, the CDP has been in development since 1998 and was incorporated into the

SDCWAs 2003 Water Facilities Master Plan and the 2005 UWMP. All required permits and environmenta

RecycledWaterOpportunities

AlthoughtheDistrictprovidesrecycledwatertoitscustomersforlandscapeirrigationandindustrialuse,the

District isnotawastewatercollectionortreatment facility. Currentrecycledwatersuppliesarepurchased

directlyfromtheCitysHaleAvenueResourceRecoveryFacility(HARRF).

HARRF is an activated sludge, secondary treatment facility, consisting of physical, biological, and chemica

treatment methods, which includes screening, sedimentation, chemical precipitation, and biologica

processes. HARRF is designed to treat a flow of 18 million gallons per day (MGD). HARRF processes waste

watertheCityandtheRanchoBernardoareaoftheCityofSanDiego.Operating24hoursaday,theaveragedailyflowis15.6MGD,whichiscomprisedofEscondido'sflowof11.8MGDandRanchoBernardo'sflowof3.8

arelimitedbytheHARRFscapacitytoproducerecycledwater.

The District contains one brewery within its service area that is discharging significant amounts of process

water intotheCityssewagesystem. Approximately70%ofitswaterdemand isdischargedaswastewater

and is likely to contain spent grain and grain dust, fermentation solids, yeast waste, sodium, acids, caustic

RegardlessofthenumberofsourcesofwaterwiththeDistrictsportfolio,watersupplies,whetherpotableor

recycled, are subject to inconsistencies that can affect the quantity of water at any given time. Those

inconsistencies include limitations due to pumping, contracts, or agreements, legal issues, environmenta

issues, water quality issues, climatic drought, and emergencies interruptions. Table 23 summarizes those

inconsistenciesforbothpotableandrecycledwater.

On June30,2009, theDistrict implementedaLevelTwoDroughtAlert, inresponse totheSDCWALevel2

declarationonApril23,2009. TheSDCWAdeclarationmandatedan8%reductioninwaterdeliverstoeachof

The District has considered the financial implications of both longterm and shortterm water shortages

Currently, the District commodity rate comprises approximately 70% of the Districts revenues, while fixed

chargesareapproximately30%. Inshorttermwatershortages(lessthan6months),thefluctuationofrevenue

would be managed through the Districts reserve funds. Longer shortages however, would require an

adjustmentofthecurrentratestructuretoinsureadequaterevenuesforDistrictoperations.

WaterQuality

As required by federal and state governments, the District publishes a Consumer Confidence Report (CCR

each year. The CCR lists all constituents found in District water, the source of those constituents, testing

standardsthatmustbemet,arangeoftestingresults,andnoncomplianceeventsthatoccurred,ifany. The

Currently, the District imports all of its potable water from the SDCWA. The SDCWA in turn purchases its

waterfromMWD. MWDimportsitswaterfromtwosources,a242mileaqueductwhichtransportsColorado

In December of 2002, MWD completed its source water assessment of its source water. Colorado River

supplies are considered to be most vulnerable to recreation, urban/storm water runoff, increasing

urbanization, and wastewater. State Water Project supplies are considered to be most vulnerable to

urban/stormwaterrunoff,wildlife,agriculture,recreation,andwastewater.

The District is a signatory to the Memorandum of Understanding Regarding Urban water Conservation in

As a member of the CUWCC, the District has agreed to make a good faith effort to implement the Best

ManagementPractices(BMPs)inordertoaddresstheDemandManagementMeasures(DMM).

In December 2008, the BMPs were substantially revised by the CUWCC and updated in order to reflect

advancesandchangesinwaterconservationpracticesandtechnologies.In2005,therewere14BMP.These

BMPsarenowdivided into fivecategories. Twoof thesecategories,UtilityOperationsandEducationhave

been labeled as Foundational BMPs because they have been classified as essential water conservation
