City Council Memorandum Public Works & Utilities Memo No. UA24-078

Date:

June 27, 2024

To:

Mayor and Council

Thru:

Joshua H. Wright, City Manager
Andy Bass, Deputy City Manager
John Knudson, Public Works and Utilities Director

From:

Danny Sargent, Water Systems Senior Manager

Subject:

Purchase of Vacuum Excavator Truck

Proposed Motion:

Move City Council approve the purchase of an 18" Hydro-Excavator Vacuum Truck, from Haaker Equipment Company, utilizing Sourcewell Contract No.101221-VTR, in the amount of $634,753.35

Background/Discussion:

The Water Distribution Division maintains approximately 1,240 miles of potable water mains and associated underground infrastructure throughout the city. The amount of underground infrastructure requires frequent excavation to maintain and repair these facilities. Excavating with mechanized equipment, such as a backhoe or excavator, is often not desirable due to the number of city-owned and private utilities within the right-of-way that could be damaged in the event of a main repair. This work requires the use of a contracted vacuum excavator truck (also known as as "vactor truck") service, as the city currently does not own this piece of equipment. Additionally, the Pecos Surface Water Treatment Plant (PSWTP) utilizes a contracted vactor service to clean equipment and basins throughout the year. This purchase will also offset those contractual services.

Currently, Water Distribution spends $74,000 per year on contracted vactor truck services (four-year average). The PSWTP spends $40,000 per year on contracted vactor truck services. Based on the average spending and factoring in operational costs, the return on investment will be approximately seven (7) years, with an estimated savings of $440,000 over the 12-year expected lifespan of the equipment. Additionally, service to the citizens of Chandler will be enhanced through reduced main break repair timeframes.

Evaluation:

Sourcewell competitively solicited and awarded contracts for combination sewer cleaners, water jetters, and vacuum excavators (vactor trucks). The city has current agreements allowing for the cooperative use of Sourcewell contracts. Staff recommends use of the Sourcewell contracts which is valid through November 29, 2025, for the most expeditious and competitive purchase of a vactor truck.

Financial Implications:

Funding for this contract is contingent upon City Council adopting the Fiscal Year 2024-2025 Budget.
