Background

The City of Lawrence Wastewater Treatment Plant processes and treats approximately 8.7 million gallons of wastewater per day. From the treatment process, approximately 9,000 cubic yards of biosolids is land applied yearly to privately owned agricultural properties since 1994.

Project Description

Currently, the biosolids are in cake form (about 18 – 23 percent solids). Typically, before planting and after harvest, biosolids are hauled to the agricultural site and spread at an agronomic rate to match the field and crop nitrogen requirements. This is then incorporated into the soil using a disc. All activities must be conducted in a manner, which meets all existing regulations and requirements and shall not negatively affect the City’s public relations and existing relationships with area farms.

Project Status

Request for proposals were received and reviewed. Nutri-Ject Systems Inc. met the City’s specifications and utilized methods to meet the proposal description without a negative effect to the City’s public relations and existing relationships with area farms.

Nutri-Ject Systems Inc.

$14.95 per cubic yard

Project Funding

The project will be funded from the Department of Utilities 2016 Operations & Maintenance fund.

Action

Authorize the Interim City Manager to enter into a contract with Nutri-Ject Systems, Inc. for the 2016 Biosolids Land Application with the option to extend for additional years at both parties consent and to allow for inflationary increases.
