Water Budget Rates

Understanding Monthly Water Budget Rates

Like other water agencies across California, EVMWD is faced with dwindling water supplies and rising costs for imported water. EVMWD is restructuring to a more flexible monthly water budgets designed to manage the state’s precious water supply and allow customers to have access to more water during the warmest days of the year.

What are Water Budgets?

A water budget is a monthly amount of water allocated to you for efficient indoor and outdoor uses at your property. Just as you budget your finances, a water budget gives you a monthly target so you can be most efficient with the water that you use.

Another way to look at it… Buckets of Water

You can think of your water budget as buckets of water. The first bucket should be plenty for your efficient indoor use and costs the least. The second bucket should be plenty for your efficient outdoor use and costs slightly more. If you are not as efficient as you could be, you can buy another bucket, but it will cost you more. If there are holes in your bucket and you don’t fix them, then you’re wasting water and you will pay the most for that bucket.

Why use Water Budgets?

Rate structures using water budgets are a very fair way to encourage efficient water use and discourage water waste. In simple terms, those who use water efficiently both indoors and outdoors -- those who stay within their budget -- will pay less than customers who are inefficient or wasteful.

How are Water Budget allocation determined?

EVMWD water budgets are based on a scientific formula that uses data from local weather stations to determine how much water plants need to survive in EVMWD’s service area. Water budgets increase as the plant water needs increase. Therefore, in order to provide more flexibility for our customers, EVMWD is changing to monthly water budgets to give each customer more water during the hottest part of the summer and during extraordinarily warm days in late spring and early fall.

The change to monthly water budgets can also be thought of as buckets. EVMWD will give you slightly larger buckets for the hottest and driest months of the year. This will allow you to stay within your water budget at the more cost effective rate when water is a necessity. In turn, buckets will now be a little smaller during the cooler, wetter months.

Meet Elsinore Eddie

 

Elsinore Eddie is a typical customer of EVMWD. His yard is well-kept with grass, shrubs and a section of native plants. The size of the area he waters is about 4,700 square feet or about 60% of his property.

EVMWD knows Elsinore Eddie needs enough water to care for his family of four and landscaping, so the district has designed a rate structure that will provide plenty of water for both and encourage efficiency at the same time. Basically, Eddie and EVMWD customers who use water efficiently, both indoors and outdoors, will pay the lowest rates. Below is a sample of an average bill.

These numbers are based on the average EVMWD customer, Elsinore Eddie. Like nearly 20,000 other customers, his home sits on a parcel that is .18 acres or about 7,840 square feet.

How do I calculate my monthly bill?

The following examples are based on 30 day bills, and assumes 4 persons in the home and irrigated landscape size of 4,704 sq. ft. Water budgets are calculated daily so no matter how many days there are in a billing period, customers will benefit from a water budget based on the actual number of days billed. Please note, the outdoor budget is in addition to the indoor water budget.

Block 1- Low Volume Discount: Indoor Water Budget

Formula:

# of persons in home [defaulted to 4] x 60 gallons per day (GPD) = Block 1 Daily Budget

Example: 4 Persons x 60 GPD = 240 GPD

30 Billing Days x 240 GPD= 7,200 Gallons, or 9.6 CCF (Billing Unit, 1 CCF = 748 Gallons)

Block 2- Conservation Base Rate: Outdoor Water Budget

Determined by a formula that includes the amount of water various types of landscape plants need to survive, square feet of your property’s irrigated area and the typical weather for the time of the year.

Formula:

[(Monthly ETo* x (.60)Landscape Needs Factor**) / Gallon Conversion Factor] x Area (sq. ft.) of Landscape = X gallons

X gallons/Gallon to CCF Conversion Factor (748) = CCF- Block 2 Monthly Budget

Example for month of July:

[ 7.82 x .60) / 1.6043] x 4,704 sq. ft. = 13,757.51 gallons

13,757.51 gallons / 748 = 18.4 CCF
