Operations
 
Details: SUMMARY: Review progress on treatment upgrades DETAILS: System operating on filters 1, 3, and 4. Filter 2 upgrade is close to being done. New filter 5 should be ready soon after filter 2. The former backwash tanks to the west are designed as a pair of baffled clearwells and will be used as such with chlorine as the only disinfectant (ammonia will be added after these tanks). Flocculation and settling basins are working well with settled water turbidity as low as 0.2 NTU. Lamellar plates also effective and a relatively new design. Corrosion control feed system will be upgraded. North Spit WTP has only been needed for a few days thus far. ACTION NEEDED: Ask for plans on the changes to corrosion control feed.
