Water rate increases of an average of 5 percent will go into effect Monday, the county Department of Water Supply reminded residents.
The higher water rates are expected to raise $3 million in additional revenue to pay for water system repairs and offset increases in electrical expenses, debt service and higher operations and maintenance expenditures, the department said.
Beginning Monday, residents of a single-family dwelling will pay $1.80 per 1,000 gallons for the first 5,000 gallons consumed, then $3.35 per 1,000 gallons for from 5,001 to 15,000, then $4.95 per 1,000 from 15,001 to 35,000 and $5.65 per 1,000 thereafter.
All other general usage customers pay the same as single-family residents, although after 35,000 gallons, general usage consumers continue to pay $4.95 per 1,000 gallons.
Agricultural consumers pay $1.15 per 1,000 gallons after reaching 15,001.
Also, for the first time since 2002, water system development fees were increased to "more accurately reflect the actual cost of providing water service." Those fees doubled under the rate increases. For example, the system development fee for a standard 5/8ths-inch meter jumped from $6,030 to $12,060.
"These rates have long been inadequate for covering source, transmission and storage costs for adding customers to the existing system," water officials said.
Maui County Council members approved the new rates for the fiscal 2014 budget, which goes into effect Monday.
