These numbers are based on data reported by the "Santa Fe New Mexican" on February 16, 2001. They were taken from report titled "Water Use in Santa Fe" produced by the city's planning de (See table) p g partment. The table proves once more what we, carwash operators, new all along, namely that commercial carwashes, as an industry, are far from being major users and compare favorably with other business establishments. - ss It is interesting to note that the water consumption found for full service car washes is the same as the average of my two car washes. This works out to about 50 gallons per car, including all incidentals, such as toilets, washing towels, cleaning of the lot and watering landscaping. The article did not report on other possible medium and large users, such as: Laundromats, sport clubs and gyms, commercial bakeries, nurseries, commercial laundries, soft drink bottling plants and manufacturing plants. It would have been interesting to include these type of users in the tabulation. However armed with just the published numbers, we can be well prepared to inform the public, the bureaucrats and the politicians, how we as an industry stack up with other business. Once this is clear, all we have to do is ask to be treated like any other industry. .

April 2001 Carwash Water Usage in Perspective City of Santa Fe, NM, study shows that carwash water use compares favorably with other industries WATER USAGE BY CATEGORIES OF USERS By Henry F. Weinschenk Y Comparision Express Car Wash Company, Inc. c Gallons Comparison RI Type of User Per Day If Home = 1 If Full Serve er Yes, the numbers are out! A 300- y ome Carwash = 1 room full service luxury hotel, at 1 Full Service Hotel, 300 Rooms 87,000 390 13 87,000 gallons per day ( "gpd ") uses 2 High School, 1,500 Students 36,000 162 5 13 times more water than an average 3 Middle School, 500 Students 27,000 119 4 4 Motel, 150 Rooms 20,000 90 3 full service carwash. At 6,700 gpd, a 5 Grocery Store, 80,000 Sq.Ft. 7,900 35 1 full service car wash uses only 27% 6 Automated Car Wash 6,700 30 1 more water than a typical sit -down 7 Sit -Down Restaurant 5,300 24 0.8 8 Irrigated Park Turf, 3 Acres 4,800 22 0.7 restaurant, which comes in at 5,300 9 Manual Spray Car Wash 3,100 14 0.5 gpd. Self service carwashes, at a 10 Fast Food Restaurant 2,200 10 0.3 typical 3,100 gpd are not all that far 11 Medical Office, 15,000 Sq.Ft. 2,000 9 0.3 above a fast -food restaurant at 2,200 12 Elementary School, 250 Students 1,800 8 0.3 13 Church with Day Care 1,200 5 0.2 gpd. Even a typical 80,000 square 14 Church without Day Care 500 2 0.1 feet supermarket outpaces a full 15 Gasoline Station 400 2 0.1 service car wash at 7,900 gpd. A 150 16 Single Family Home' 200 1 0.03 room motel uses 3 times the water that 17 Apartment, Condo or Mobile Home 180 0.8 0.03 18 Sr. Citizen Retirement Apartment 130 0.6 0.02 a full service carwash uses and a 1,500 19 Retail Store, 2,000 Sq.Ft. 110 0.5 0.02 student high school uses almost 5 and a half times as much water. These numbers are based on data reported by the "Santa Fe New Mexican" on February 16, 2001. They were taken from report titled "Water Use in Santa Fe" produced by the city's planning department. (See table) The table proves once more what we, carwash operators, new all along, namely that commercial carwashes, as an industry, are far from being major users and compare favorably with other business establishments. It is interesting to note that the water consumption found for full service car washes is the same as the average of my two car washes. This works out to about 50 gallons per car, including all incidentals, such as toilets, washing towels, cleaning of the lot and watering landscaping. The article did not report on other possible medium and large users, such as: Laundromats, sport clubs and gyms, commercial bakeries, nurseries, commercial laundries, soft drink bottling plants and manufacturing plants. It would have been interesting to include these type of users in the tabulation. However armed with just the published numbers, we can be well prepared to inform the public, the bureaucrats and the politicians, how we as an industry stack up with other business. Once this is clear, all we have to do is ask to be treated like any other industry. 1. Based on a report released by the City of Santa Fe, New Mexico, as reported by the "Santa Fe New Mexican" newspaper on February 16, 2001. System wide water use per person per day: 143 gallons = Total water use dived by total population, as published in "Santa Fe Trends 2000 ", City of Santa Fe. V 0 O IX 10 CD r. E a '� 'Fri o..4 . c).
