Authorize the City Manager to execute purchase orders not to exceed $200,000 for any individual pre-qualified plumbing contractor and $1,000,000 total for all plumbing contractors for 2018 private property inflow and infiltration repairs associated with Project UT1305 Rapid Inflow and Infiltration Reduction Program (CIP #UT9909). |

Executive Summary: |
The 2012 Wastewater Master Plan and Capital Improvements Program recommended a Rapid Inflow and Infiltration (I/I) Reduction Program within the area of the City that generally flows by gravity to the Kansas River WWTP (KRWWTP).
A voluntary program was established to identify and repair cost effective private property sources. The types of sources targeted include sump pumps, foundation drains, area/stairwell/driveway drains, and defective cleanouts that direct rain and groundwater directly into the sanitary sewer system. After program staff have identified a source and City staff approves it as cost effective, the property owner selects a pre-qualified plumbing contractor to complete the repair at the City’s cost. All repairs are invoiced on previously negotiated unit rates with detailed specifications for each type of repair. Besides providing program oversite, property owner consultations, and building permit inspections, Utilities Department staff complete minor repairs such as cleanout cap replacements.
A total of seven area plumbers are currently pre-qualified and under contract to complete major repairs under the program. City staff anticipates adding one additional pre-qualified plumber to the program in early 2018. The number of projects assigned to each pre-qualified plumbing contractor can fluctuate depending on the number of sources approved for repair and the individual property owner’s plumber selection.
Due to the variation in work assignments resulting from the private property owners’ ability to select their preferred plumbing contractors, total yearly expenditures have varied between $75,000 and $200,000 per pre-qualified plumbing contractor. Efficient management of the variations in these contracts requires flexibility in processing purchase orders and change orders. The recommended action would set a maximum yearly total of $200,000 per pre-qualified plumbing contractor and $1,000,000 combined for all plumbers through the end of 2018. This would improve the efficiency with which these contracts are managed. The request is funded within the $2.83 million adopted budget for this project.
Program Background The area of focus for the I/I program is an older part of the City and has the largest influence on the peak wet weather flows at the KRWWTP due to its proximity to the plant and higher levels of I/I. The goal of the program is to reduce wet weather flows from this area by 35% in order to eliminate the need for large scale capacity expansion projects in the Burroughs Creek interceptors and the KRWWTP. Obtaining this reduction goal is not feasible by only addressing issues within the public sanitary sewer system.
The Private I/I Abatement Program was branded as the Ecoflow Program and private plumbing evaluations were started in June 2014. Department staff along with TREKK Design Group, have conducted private plumbing evaluations for three years. To date, over 5,200 private properties have been evaluated and over 1,500 repairs have been completed. The response from the public, including property owners, property managers, real estate agents, USD 497, and neighborhood associations, have been overwhelmingly positive. The program has achieved response rates between 75 percent and 90 percent in targeted areas with only 385 property owners declining to participate.
In 2017, program staff has targeted the neighborhoods around Schwegler and Hillcrest Elementary Schools for private plumbing evaluations. The number of identified qualifying defects per property has been lower in these areas since the overall age of housing stock is much newer compared to other sections of town previously targeted by the program. Starting in 2018, program staff will target the Old West Lawrence Neighborhood and parts of the Oread Neighborhood. Toward the end of 2018, the program will shift its focus to Downtown Lawrence and immediately adjacent residential neighborhoods. An increase in the number of qualifying repairs is anticipated in this area due to the advanced age of the neighborhoods.

Fiscal Impact (Amount/Source): |
The 2018 Rapid I/I Reduction Program (CIP #UT9909) is funded in the 2018 Capital Improvement Program (CIP) ($2.83 million). The recommended action would result in encumbrances not to exceed $1,000,000 of the funds budgeted for this project and authorization for the City Manager to approve purchase orders up to $200,000 per contract on an as needed basis. Approval does not guarantee that 100 percent of the encumbered funds will be spent on the plumbing contracts, but it improves the efficiency of the management of these contracts. |
