Discussion and possible action on any and all matters regarding the engagement of WestLand Engineering and Environmental Services to conduct a service line material inventory.  (Jorge Perez, Assistant Director of Public Works)

Effective beginning December 16, 2021, all Community and Non-Transient Non-Community public water systems are required to identify all service lines connected to their distribution system, regardless of the usage of the water, and distinguish any service lines made of lead or of unknown material (40 CFR §141.84(a)). The complete inventory will require characterization of all service line materials (lead, galvanized, copper, and plastic) and will be due to the Arizona Department of Environmental Quality (ADEQ) by October 16, 2024 (40 CFR §141.80(a)(3)).
 
The Department of Public Works and its Water Division obtained a proposal from WestLand Engineering and Environmental Services from Tucson, Arizona. WestLand proposes to complete a lead service line inventory and associated documentation following Code of Federal Regulations (CFR) requirements (40 CFR §141.84). The inventory will classify all service lines and portions of service lines in the system as lead, galvanized requiring replacement, non-lead, or lead status unknown. The inventory will estimate the number of high-risk service lines and describe the reliability of existing records, thereby providing important information for planning service line verification and replacement efforts.
 
Staff is seeking Mayor and City Council approval to engage WestLand Engineering and Environmental Services for this project in the amount of $55,197.00 as authorized under City Code Section 3.05.080 - Professional Services.
