About this opportunity
Las Gallinas Valley Sanitary District is requesting proposals for a wet-weather flow monitoring study and inflow and infiltration assessment of approximately 163,000 linear feet of gravity sewer in the John Duckett Basin, with proposals due September 22, 2026.
The scope requires locating, quantifying, and ranking sources of inflow and infiltration within the basin to enable the District to prioritize rehabilitation spending on segments yielding the greatest reduction in wet-weather flow. Qualified firms must demonstrate technical expertise in wet-weather monitoring methodologies and I&I assessment across gravity sewer systems of comparable scale.
The District will evaluate proposals based on technical qualifications, experience, and proposed methodology. Evaluation criteria and any stated weighting are not specified in the available notice. No contract value, term, or incumbent information is disclosed. The project is funded through the District's infrastructure rehabilitation program and covers service areas spanning Marin County and San Francisco City in California.
