Specifications include, but are not limited to: The City of Independence (the City) is requesting bids for hauling solids from the water treatment plant (WTP) residuals lagoon to sites approved by the Kansas Department of Health and Environment (KDHE). Though hauling of this material is not anticipated to interfere with WTP operations, coordination with staff will be required. Contractor shall deliver up to 3,400 cubic yards of solids from the WTP residuals lagoon to the KDHE-approved disposal sites. Maintain the residuals lagoon site, disposal sites, and routes to the site to ensure ample room for solids loading and ease of truck turning. Coordinate with landowners of disposal sites, as required. Oversee the loading operation, review the forms, and maintain records. Property 1 includes approximately 17 acres of generally flat grassland. The City uses a portion of the property for disposal of tree limbs/brush. Property 1 and structures, water wells, and water features located within ½ mile are shown on Figure 2. Though a natural drainage pathway is located to the east of Location 1, the FEMA flood map labels it as an area of minimum flood hazard. The Contractor shall not apply the solids within 100 feet of the natural drainage pathway or property lines. Property 2 includes approximately 22 acres. The western portion of the property is generally flat. Rock Creek runs north/south through the middle of the property. The western portion of the property is within the floodplain and is mostly covered with trees. The Contractor shall not apply the sludge within 100 feet of the natural drainage pathway or property lines. Property 2 and structures, water wells, and water features located within ½ mile are shown on Figure 3. Property 3 includes approximately 80 acres of agriculture flat land owned by the City. It is bordered by wooded areas near the River and the City’s wastewater treatment plant (WWTP). Since most of the property is located within the floodway, incorporating the sludge into the soil and monitoring weather applications during the application timeframe will be especially important for this location. The property and the surrounding area is shown in Figure 4. Property 4 includes multiple parcels of City-owned land near the airport for a combined total of approximately 155 acres. The properties are primarily used for agricultural purposes with some areas of grass that are regularly mowed. Solids application at the airport will have the additional requirement of a 150-foot separation between the sludge application area and the runways. The property and the surrounding area is shown in Figure 5.
