STAFF ANALYSIS
CIP Project #60075 – Bullard Water Campus (BWC) Pre-Filter Replacement will provide final construction services for the project. In general, the proposed improvements include demolition of the existing 10-micron filters at the BWC. The current filters are 16 years old and have reached the end of their operational life cycle. Staff routinely perform repairs and modifications to the filters to maintain their functionality. A pre-design study, including particulate size distribution (PSD) testing, was performed. The study results did not support in-kind or similar replacement for the 10-micron pre-filters. The PSD results showed that less than 1% of the particles were larger than 10 microns and would be captured by pre-filters. The study recommended the installation of sand filters at each well site in lieu of 10-micron pre-filters at the BWC.
The project scope shifted to detailed design, construction, and commissioning for sand separators at Well 19, Well 22, and Well 26. The installation and maintenance of 3 sand separators proved to be more economical than the replacement of the existing pre-filters.
This Council Action Request is to obtain authorization for the expenditure for the construction of CIP Project #60075 – Bullard Water Campus Pre-Filter Replacement.
