In previous years, our System Process was shown to increase. We do no believe this to be accurate because an increase in population would also be an increase of water used, therefore eliminating some of the need to flush. However, if line extensions are installed with few connections on them, the need for flushing could remain the same.

Concerning the question of additional supply, the aforementioned 4 MGD water treatment plant is presently under construction. In fact, the contractor is ambitiously declaring that they will be substantially complete by October 1, 2025. We (ICWD) do not believe that will be the case. At best, we estimate that substantial completion will not be achieved until sometime in December 2025. Regardless, that exemplifies that construction is underway and is not too far from being complete.

Finally, in what may be relevant, ICWD presently has a supplementary/emergency contract with Spartanburg Water. This is a “use if you need it” contract, for up to 2 MGD. It is a 5 year contract that I expect will be renewed, but one never knows. It is set to expire in July of 2027. We obtained this additional 2 MGD to ensure Polk and ICWD would have an abundant supply at least until the WTP was constructed, but our desire is to keep it as long as the terms do not change in 2027. We have not had to use it to meet capacity, but it has been comforting to know it was there.

The Inman-Campobello Water District hopes to complete construction of a 4 mgd water treatment plant in late 2025.The intake will be on the North Pacolet River. The ICWD has a permit to withdraw up to 8 mgd. This water will be used to supplement both the Polk County Water System and the ICWD.

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 68 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?   The Polk County Water System purchases an average of 4.038mgd from the BRWA. OF that the ICWD consumes 3.688mgd on average. Polk County water system has a contract with BRWA that will allow us to purchase 6.1mgd. BRWA will allow the ICWD to exceed the contract amount provided the capacity is available at that time. The ICWD also has a connection to Spartanburg Water System (SWS) and has a contract for 2mgd with the ability to provide more if needed. SWS has a treatment capacity of approximately 80mgd and presently sells 30mgd The ICWD's entire distribution can be served by SWS if need be. This would make the entire 6.1mgd from BRWA available to Polk County water. The ICWD also has a permit allowing us to withdraw 8mgd from the North Pacolet River. The ICWD has begun construction of the treatment plant on the North Pacolet River. We plan to build 4mgd at this time and will add the other 4mgd when it is needed. We expect construction to be complete before the end of 2026.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   Polk county purchased Lake Adger in 2009 for the purpose of having future water supply. If the county were ever to need a water supply other than the BRWA and the ICWD, Lake Adger will be available.

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