HOW TO READ OUR FORM
A. The amount of water used each year is found by adding up the totals for each EBMUD billing cycle (a billing cycle consists of 2 months). Six billing cycles are totalled for each year of the survey. The number of days in the billing cycle is multiplied by the gallons of water used per day. You will see that for each year there is a total for each billing cycle (see lines 1-6). The totals for each year are found by adding up the totals for each billing cycle. The number at the bottom of each box is the approximate total gallons used for that year.
B-C. Once we found the total gallons used each year we subtracted each subsequent year from the base year. In most cases 1987 was used as the base year. For clients who participated later their first year is their base year. The base year is used as a comparative figure. If the number is positive, the result of the subtraction is the total gallons saved for the subsequent year. If the resulting number is negative then this reflects the increase in gallons of water used for the subsequent year. Each subsequent year is subtracted and the results are added together to determine the approximate total number of gallons saved during the drought period.
D. We noted how many years water was saved and divided the total by the number of years to determine the amount of gallons saved per day over the 1-6 year period.
E. We divided the gallons saved per year by 12 to determine the total gallons saved per month.
F. The gallons saved per month were divided by 30.4 to illustrate the total gallons saved per day each month.
G. The approximate gallons saved over the survey period were divided by 750 to determine the total number of units saved. The total number of units saved was divided by 1.37 to determine the total dollar amount saved by Water Management.
A. On this worksheet you will find the irrigation types found in the front and back of the client's lawn and landscape. We have checked the box under each heading to indicate which particular sprinkler type the client uses in that area. The category called "other" includes sprinklers that are no longer on the market as well as those yards that do not contain any irrigation at all.
B. The bottom part of this worksheet shows the approximate size and square footages of each lawn and landscape. The sizes are approximated because the time involved in measuring each and every lawn and landscape would become overwhelming and we simply did not have the time to accomplish such a feat. Though maybe not 100% accurate, our approximations are at least 85% accurate.
Most lawns are broken up by driveways or walkways. To illustrate these breaks, we divided the lawns up into sections: single, middle, left and right
Since landscapes are so varied, we simply divided them into front and back, with a box for landscapes over 10,000 sq. ft. and one for landscapes under 10,000 sq. ft.
PLEASE NOTE: These sizes are included just to give you an idea how much water is reasonable for each yard to use, and to show what kinds of irrigation is being implemented. Different systems use water differently. For instance, pop-ups put out less water than impacts, and single spray rotaries put out more water than multiple spray rotaries. Drip irrigation systems put out less water than all of these. Although drip irrigation systems are a little more expensive to install, they are becoming more popular among homeowners. Drip is more popular now than it was in 1988. We have found throughout these homes that the landscaper did not take the possibility of a drought into consideration when the irrigation systems were put in. Had they thought about it they would have better selected the types of sprinklers for each yard. In most cases the bottom line for the landscaper was whatever system was most cost efficient to install. This example illustrates my point; if a lawn is 10,000 sq. ft. and is run on pop-ups, maybe it would do better on single spray rotaries. The effectiveness of the water amount depends on the type of irrigation system that is being used.
