The Olivenhain Municipal Water District (District) is issuing this Request for Statement of Qualifications (RFSQ) to invite qualified contractors (Respondents) to submit a Statement of Qualifications (SOQ) by June 26, 2026 that demonstrates Respondents ability to provide construction services for the Districts Membrane Basin Rehabilitation Program (Project), including replacement of the Combined Influent and Backpulse Pipe (CIBPP). The Project is located at the Districts David C. McCollom Water Treatment Plant (DCMWTP) located at 19090 Via Ambiente Road in Escondido, CA.

Only general contractors that are determined by the District to be pre-qualified will be eligible to participate in bidding. The District is undertaking a multi-year capital rehabilitation program to restore and extend the service life of critical membrane treatment infrastructure at DCMWTP. The Project will be delivered through a phased construction approach to maintain continuous plant operation as much as possible while rehabilitating multiple concrete membrane basins, replacing protective liner systems, and performing associated structural, mechanical, and coating improvements. The replacement of the CIBPP will be during the first year of the program only. The District is seeking qualified contractors with demonstrated experience performing complex rehabilitation work within an active water treatment facility and with submerged membranes. The issuance of this RFSQ is the first of a two-step procurement process further described in Section 4.1. This is a six-year program, with the intent to award the first package including Years 1 and 2 of the proposed work, and with a District option to award work for subsequent years, based on performance.
