Wastewater Master Plan

SECTION I - GENERAL

    In the planning process, it is necessary to analyze every detailed aspect of an operation. The publishing of some of the detailed information creates potential vulnerabilities to the City of Lawrence's Utilities operations and therefore, certain aspects of the data gathered this master planning process is not being published in this release of the consultant's findings and recommendations. The complete package of information collected for analysis for this master plan may be viewed at the City of Lawrence Department of Utilities by appointment. To arrange a time for viewing please contact Chris Stewart, Assistant Director- Water at (785) 832-7814 or Dave Wagner, Assistant Director - Wastewater at (785) 832-7807 or email dwagner@ci.lawrence.ks.us.
