1 WMWD Efficiency Evaluation Program RFP Clarification The following information was developed based on questions received from interested parties and is intended to provide clarification to the Efficiency Evaluation Program Request for Proposal released on March 21, Western Municipal Water District (Western) will accept irrigation auditing certification from an irrigation technical school, or similar, in lieu of the Irrigation Association certification as long as all of the following conditions are met: a. the certification was acquired and is held by the individual that will conduct the proposed audits; b. the certification requires periodic renewal and/or continuing education units; and, c. the individual has held the certification for at least two complete years. 2. Western will accept proposals from entities that did not submit a declaration of interest. However, the scoring matrix used to evaluate received proposals includes points for submission of a declaration of interest. An entity that did not submit a declaration of interest will not receive points in that category. 3. Western is requesting sample reports from proposers in order to evaluate the knowledge and communication skills of each respondent. Western will work with the selected vendor to further evaluate the content, format and delivery of their reports. Western may incorporate portions of the selected vendor s reports into reports provided to its customers. A sample residential efficiency report, generated prior to Western s use of the tablet survey tool, is provided as a reference. Proposers can use this to estimate the field and office time required to generate a customer report. The selected vendor will use Western s tablet survey tool for conducting single family evaluations and producing customer reports. The survey tool and the associated reports are proprietary to Western. As such, they will be shared with the selected vendor upon contract award for use only within Western s service area. Large landscape and commercial reports are currently generated using basic Word and Excel templates developed and provided by the current vendor. Western plans on transitioning large landscape reporting to the tablet tool by the end of Fiscal Year 13/14 and commercial reporting by the end of Fiscal Year 14/15. For further clarification, Western is providing example data points collected during the field visit or using in the report only as a reference. The following is provided only as an illustration. Actual data collected is subject to change and is site dependent.

5 Area Description Your home at was evaluated on. Irrigation at this property is moderately efficient but offers a high opportunity for water and dollars savings through improved efficiency. Existing Irrigation Equipment: 1 stand alone controller Mixture of spray heads, rotors, and low flow irrigation 4,250 square feet of landscape irrigated area Recommendation #1 Replace your old irrigation controllers with a new Smart Controller. Rebates for Weather Based Irrigation Controllers (WBICs) Option 1: The Metropolitan Water District (MWD) and its member agencies, through the SoCalWater$mart residential program offer a limited number of rebates each year for WBICs, sprinkler nozzles and many other water saving devices. Rebate amounts are: $80 per WBIC for less than 1 acre of landscape; $25 per station for more than 1 acre Applying for Your Rebate: Go to to find out whether funding is currently available for WMWD. There is a link at this website that walks you through the reservation process. Also note that funds are limited and you must make a reservation prior to purchase and installation of devices. Option 2: Western Municipal Water District rolled out Smart Yard to provide its customers with a simple and highly effective water use efficiency program that will save one billion gallons of water over 10 years. Western MWD will provide an instant rebate of 50 percent of product (WBIC) and installation costs; participants can also elect to pay the remaining 50% balance through their water bill at a fixed monthly fee over time with zero-interest financing from Western. Go to to begin eligibility review customized to your home site or call Installation of a new Smart Controller (WBIC) is estimated to save you 19,000 gallons of water per year

6 Recommendation #2 Replace existing turf spray nozzles with High Efficiency Nozzles. -25 nozzles installed in front turf area. Installing high efficiency nozzles will help reduce misting and runoff. Application rate of water is lowered, which gives plants and increased opportunity to absorb water. Installation of a High Efficiency Nozzles is estimated to save you 1300 gallons/nozzle per year. Go to to apply for 25 free high efficiency nozzles. Recommendation #3 Make repairs and retrofits to your irrigation system. Repair and/or adjust low sprinkler heads, mis-aligned heads, broken heads, pipe breaks, and appropriate retrofits. Making these repairs and retrofits could result in water savings of 10-20% on your water consumption. Stations of Concern; Broken irrigation piping, excavate and repair. (Station; 1) Low and tipped sprinkler heads, causing blocked and inefficient spray patterns. Raise and straighten sprinkler heads to increase sprinkler coverage. (Stations; 1, 2) Leaking drip adapters and tubing. Replace leaking drip adapters and install missing emitters onto drip tubing. (Station; 3) Leaking valves, replace. (Station; 4) Poor sprinkler coverage. Reposition sprinkler heads to corners and perimeter at head to head spacing so that distribution uniformity is increased and overspray in decreased. (Station; 7) Replace spray heads with in-line drip irrigation. This will increase efficiency by reducing overspray, blocked spray and runoff. Necessary equipment listed on page 9. (Stations; 9, 11, 13, 17) Cut and severed valve wiring, re-wire and connect valve wiring. (Stations; 22, 23, 24) Refer to pages 6 & 7 for a seasonal irrigation schedule for your current controller.

7 Recommendation #4 Remove non-functional lawn and replace with low water using or drought tolerant plant material and low precipitation irrigation system. Each square foot removed could save approximately gallons of water per year depending on the replacement plants and irrigation system. Turf grass commonly used landscapes consumes a large percentage of a site s water use, and the amount of water it takes to keep your lawn green during Southern California s hot, dry summers can be very high. You can save water in your landscape by electing to remove turf grass from irrigation and replacing it with water-saving alternatives. Southern California s unique climate consists of mild winters and warm, dry summers. In order to make the most of your water-saving project and enhance water savings, we recommend that you replace turf with California Friendly plants that have adapted to and thrive in these conditions. Even low water using plants can be irrigated incorrectly. Selecting a low flow system will help ensure that water is applied efficiently. Drip, micro, low volume or low precipitation rate irrigation is the slow application of water to a plant s root zone. This delivery reduces evaporation and eliminates overspray. Plants thrive on the optimum balance of oxygen and moisture around their roots. To learn more about low flow irrigation and climate appropriate plants, refer to pages 8 & 9 or visit the program website listed at the bottom of the page. Western will pay up to $1.00 per square foot for the conversion of turfgrass to climate appropriate plants in turf conversion areas (Project areas) with a minimum of 1,000 square feet to a maximum of 6,000 square feet. The minimum project area for parkways (area between sidewalk and curb) will be 300 square feet. NEW! Design services. In addition to the incentive payment, for a fee of $25, Western will provide up to three hours consultation with a landscape designer (Designer) to assist Participants with designing their turf conversion area.

8 Water Budget Due to severe supply limitations in Southern California, WMWD has implemented a Water Budget Rate for customers. A Water Budget is the calculated amount of water a household should require per month based on the size of the family, the lot size and local weather conditions. The outdoor portion changes monthly to reflect seasonal weather changes. The water budget will be used to bill the customer based upon a tiered rate structure. The higher the water usage; the higher the billing rate. If a customer stays within their water budget, they are billed at a low per unit rate. The rate structure encourages conservation by providing an incentive to use water wisely. No matter what the budget is, a customer will only be billed for the water they use. In 2011, your property consumed 210,188 gallons (281 HCF or hundred cubic feet) of water. Your proposed water budget allocation would have been 191,517 gallons, putting your usage 18,671 gallons or 10% over allocation. Your Historic Water Usage as Compared to the Proposed Water Budget* Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Indoor Allocation Landscape Allocation Total Allocation Actual Usage *The WMWD Board of Directors has approved Water Budget allocations, as of October 1, January 2011, Water usage over water budget allocation February 2011, Water usage over water budget allocation May 2011, Water usage over water budget allocation August thru December 2011, Water usage over water budget allocation

9 Seasonal Irrigation Schedule A new water efficient seasonal irrigation schedule is provided on the following pages. The new schedule is based upon your specific site conditions including: plant types, soil type, microclimate and the existing irrigation system. If you elect not to retrofit your controller with a weather based model you can still save water by adjusting the schedule on your existing controller.

12 Low Flow/ High Efficiency Irrigation In-line drip emitter tubing 12,18, and 24 emitter spacing Polyethylene drip tubing 5/8 tubing allows drip emitters and micro-sprayers to be installed where necessary (by plant material). Valve Assembly It is important for low flow drip irrigation to install the proper equipment, which include; Low flow automatic valve Filter This helps reduce clogging. The drip emitters have small orifices that can easily Clog, therefore a filter is necessary. Pressure Regulator Drip irrigation doesn t require hi pressure, it actually performs more efficient at a lower pressure. RainBird 1800 Series Retro-Fit Easily converts existing spray body to drip irrigation. This is an alternative to the above valve assembly. 30 psi Pressure Regulator 200 mesh screen filter male-threaded swivel outlet Flush Valve A flush valve is another necessary piece of equipment. There Are automatic and manual flush valves. Flush valve should be installed at the furthest point from the connection in the drip tubing. Typical Drip Tubing Layout High Efficiency Nozzles The latest innovation in sprinkler technology is high efficiency nozzles. These low flow nozzles turn a standard pop up head into a precision irrigating device. Nozzles apply water slower and in a more uniform pattern than traditional sprays and rotors. Additional water-saving advantages include better wind resistance, less misting and virtually no run-off.
