Replacement of wemco hydrogritter

The Village of Los Lunas Public Works Department, Wastewater Division, is soliciting sole-source procurement for replacement of a WEMCO Hydrogritter grit separation system at the Village of Los Lunas Wastewater Treatment Facility, with proposals due October 22, 2026. The procurement is justified under NMSA 1978, Section 13-1-126 on grounds of proprietary design and compatibility with existing infrastructure.

The scope is complete replacement of the existing WEMCO Hydrogritter 12-inch Full Flare – Grit End (Serial No. 8296178-3) with 316 stainless steel construction. The system separates grit and abrasive inorganic materials upstream of downstream treatment processes. Replacement specifications include stainless steel tank, spiral guard, feedbox, and valve hardware; a 1/2 HP 1800 RPM motor; and associated controls. The justification notes that alternative manufacturers' equipment would require costly engineering modifications to existing piping, structural supports, and electrical systems, supporting sole-source procurement.

Falcon Environmental Corporation, located in Frederick, Colorado, is identified as the sole authorized representative and direct distributor for WEMCO (Trillium Pumps USA) equipment in New Mexico, confirmed by Trillium Pumps USA.

The total procurement cost is $120,987.00, comprising $119,300.00 for the replacement unit and $1,687.00 for freight. The estimated lead time is 25 to 28 weeks from the quote date of September 21, 2026.
