Annapolis Drinking Water Engineering Report

The city of Annapolis, located within the historical lead mining region of Missouri, has long struggled to maintain a reliable water source. Shallow wells in the local alluvium have been determined by Missouri DNR to be under the direct influence of surface water, and the city’s pressure filtration plant constructed in the 1960’s is not capable of treating surface water to the degree that is needed for safe human consumption. The city has constructed several deep rock wells in an attempt to bypass the need to treat surface water. However, local granite is known for its low water supply, and this has been evidenced in the water wells, which have proven incapable of providing enough water to reliably keep up with demand.

Heartland Engineering was hired by the city to analyze the existing water system, and provide options that will allow the city to solve their water system needs. The city is located over 14-miles from the nearest neighboring water system in Piedmont. Therefore, water regionalization is not an option. The engineering report is ongoing and will explore options such as the construction of additional deep rock wells, construction of a surface water treatment package plant, and restoring and updating the city’s existing treatment facilities to add the capability to safely treat groundwater under the direct influence of surface water. The report is anticipated to be complete by mid-2025. Funding options, including grant and loan funding, for the proposed project will also be proposed, with the most likely funding source being the Missouri DNR State Revolving Fund (SRF). The completed engineering report will be used as part of the funding application package so that the proposed improvements can be financed and constructed and so that residents of Annapolis can rest more easily in the future, knowing that safe drinking water will be readily available to them without undue service interruptions.
