2. Water Use Information

Service Area
Sub-Basin(s)% of Service Population
Waccamaw River (09-3)100 %
County(s)% of Service Population
Columbus100 %
What was the year-round population served in 2024?   2,572
What was the seasonal population and months served in 2024? (if applicable)   3,500 ( Apr May Jun Jul Aug Sep )
Has this system acquired another system since last report?   No

The 2024 population was estimated by first estimating the increase from 2023 to 2024, and then adding that increase to the 2023 population of 2469. The increase between 2023 and 2024 was estimated by multiplying the number of additional connections (49) by 2.10, the number of people per residential connection averaged over your previous five LWSPs. In doing so, this would give you an estimated 2024 residential population of 2469 + 49(2.10) = 2572.

The purpose of the above chart is to show a general indication of how the long-term per capita water demand changes over time. The per capita water demand may actually be different than indicated due to seasonal populations and the accuracy of data submitted. Water systems that have calculated long-term per capita water demand based on a methodology that produces different results may submit their information in the notes field.

Your long-term water demand is 31 gallons per capita per day. What demand management practices do you plan to implement to reduce the per capita water demand (i.e. conduct regular water audits, implement a plumbing retrofit program, employ practices such as rainwater harvesting or reclaimed water)? If these practices are covered elsewhere in your plan, indicate where the practices are discussed here.    No Changes

Are there other demand management practices you will implement to reduce your future supply needs?   No Changes

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   No Changes

How does the water system intend to implement the demand management and supply planning components above?   N/A

Additional Information

Has this system participated in regional water supply or water use planning?  No

What major water supply reports or studies were used for planning?  

Please describe any other needs or issues regarding your water supply sources, any water system deficiencies or needed improvements (storage, treatment, etc.) or your ability to meet present and future water needs. Include both quantity and quality considerations, as well as financial, technical, managerial, permitting, and compliance issues:   None.
