Restrictions on Non-Essential Water Usage/Water Conservation
City of Marengo Residents and Businesses,
The City is requesting its residents and businesses to restrict non-essential water usage as we approach and enter the coming summer months. While the City is primarily serviced by two wells, known as Well #6 and Well #7, the City is currently operating exclusively on Well #7. The City is asking that residents and business cooperate in any and all water conservation effects as we work to restore our water supply system to full operational status. This letter provides an update on the City’s water supply system as it relates to the current operation.
As stated, the City is primarily serviced by two wells, Well #6 and Well #7. Recently, while performing routine testing, City staff identified some issues in the sample taken before our treatment process occurs at Well #6. Sampling of the water after treatment raised no cause for concern or risk to the public and as such did not require notification, but the City took initiative to isolate Well #6 from the rest of the supply system while investigating the cause and contacting the Illinois Environmental Protection Agency (IEPA) as next steps in the City’s protocol.
It was at this time out of precaution that the City transitioned all water supply distribution to Well #7, which is capable of meeting the City’s water demands on the supply system, but is currently planned for future rehabilitation.
Ongoing samples and testing of the now isolated Well #6 have since shown the initial issue is on the decline with any identifiable concerns dissipating in early April 2022. However, in order to ensure the ultimate safety of the water supply, the IEPA requested and the City desired to implement a second step to treat the raw water before entering the supply system. This system disinfects the water using ultraviolet rays and is one of the most cost-effective and safe methods that can be completed and implemented within an efficient time frame. This system combined with the current treatment process that is in place would bring Well #6 back to full operational status.
The City is currently taking necessary steps to purchase and install this system; however, it takes time to manufacture and install the unit, which could be subject to supply chain issues or delays. The current timeline anticipated for project completion is +/- 8 weeks out. The City staff and engineer are working with the IEPA to ensure all necessary efforts have been and continue to be taken over the coming days/weeks until the final solution is implemented.
It is because of this delay that the City is still operating exclusively on Well #7, and is asking that residents and businesses for your cooperation in any and all water conservation efforts and to restrict non-essential water use as we work to restore our water supply system to full operational status.
