The news announced last night because of the expansion of the drought on Maui and Molokai and an especially dry summer with so many wild fires, that they are asking residents to conserve water. We still have adequate drinking water. We are not dependent on surface water. The city's main aquifers are in the dikes and the eye under the cap rock (artesian wells). We are actually drinking water that was stored 25 years ago.
Locally, farmers and ranchers though are facing more problems which will show up as shortages of meat and produce in future years.
Meterologists have predicted that the rain will come, but it won't be up to "normal" levels till December or January.
We don't have strict water restrictions. Just reminders not to water yards during the day time and not to leave water running when you soap in the shower or when you are washing to try to wash full loads. There are already restrictions for people living in townhouses and apartments that make it hard to wash a car unless you actually go to a car wash. The car washes here do recycle part of the water they use.
Actually price, determines water use. I don't like turf. If the HOA did not demand it, I would not have any at all. As it is, my sprinkler system has been off for a couple of years now and I only hand water. The grass is on its own. When it rains I use about 2k gallons a month (and I am still watering the yard). Now, it is about 5-8K a month. I am only getting a discount on 1000 gallons in sewer fees, although by their own admission they know that a house with a yard means that about 70% of the water used never goes down the drain. When I use 2K, I get no discount and the sewer fees are higher than the water fees. I guess, I use only about 1-1.5 k gallons in the house, so I have conserved a lot in the house with short showers, minimizing toilet flushes (using shower and wash water for the toilets when possible, washing full loads, and cooking large meals for 4-5 days at a time which saves water for prep and washing up, and electricity since it is cheaper to use the microwave oven than the range for cooking or reheating.
Right now it is 68 degrees but it will go up into the mid 80's 94% humidity will make it seem hotter. The winds are less than 5 mph and no rain in sight. There might be some convection heating in the afternoon, sometimes that will bring a brief shower. I always decides to rain just when I am planning to work in the yard and then it stops 10 minutes later when I am no longer in the mood. I need to remember to wear my hat. I was washing my hair yesterday and my scalp hurt. I got sunburned.
Happy gardening in Hawaii. Gardens are where people grow.
