In 2019, DHCWSC delivered 8.1 million gallons of fresh water to our 105 active customers. Water demand was highly seasonal, with July, August, and September demand exceeding 1,000,000 gallons/month, whereas in January demand was 500,000 gallons/month. From 2017 to 2019 we saw a 19% increase in demand, largely due to seasonal irrigation and new construction.
The following chart illustrate our current water consumption.
DHCWSC has three active wells whose capacity is heavily influenced by nature's past and present annual rainfall. Increasing water production is expensive and yield is not predictable.
The following chart illustrates our well depth data as of August 11, 2020.
We define exceptional consumption in excess of 10,000 gallons/month. Typically in July, 75% of the water is used by about 40% of the members, all of whom consumed over 10,000 gallons per month. Contrast this with January, when about 30% of the water is used by less than 10 members who consumed over 10,000 gallons/month. In order to encourage conservation, we increased water rates for heavy consumers in 2018. Click on Water Rate Chart below for a comparison of the 2017 and 2018 rates.
