Water Supply Update: New Membrane Could Help End Treatment-Related Water Restrictions
The biggest update from Tuesday's water supply briefing is the City's plan to secure and accelerate delivery of a replacement membrane train for the water treatment plant. The new membrane could arrive as early as late June or early July and be installed in just two days at a cost of approximately $759,000. This would allow the water treatment plant to return to its full normal operating capacity. 🎉
If the 42-inch waterline is operational as expected by the end of June and the replacement membrane is installed shortly thereafter, City Council could consider lifting the remaining Modified Stage 1 restrictions as early as July 14. That would return Pflugerville to the normal year-round conservation stage, allowing outdoor irrigation up to twice per week under the existing conservation schedule.
**Estimated Project Timeline**
• June 10 – Pumping resumes.
• End of June – 42-inch waterline expected to be fully operational.
• Late June / Early July – Replacement membrane installed, restoring full water treatment plant capacity.
• Mid-July – Major excavation and replacement work on the damaged 30-inch line expected to be completed.
• July 14 – City Council will revisit water restrictions and could consider returning to normal year-round conservation measures based on system conditions and project progress.
**Additional Updates**
• A future 1-2 day shutdown will still be needed after a header pipe failed inspection, but staff indicated it should not impact operations and may be coordinated with routine maintenance.
• The existing 24-inch bypass line will remain in service until either the 42-inch line or repaired 30-inch line is fully operational.
• Staff reported that the water treatment plant expansion remains behind schedule. Contractual completion dates have already passed, with substantial completion now estimated for October 2026 and final completion projected for December 2026. Staff indicated the reasons for the delays are still being evaluated.
Thank you to the City staff, operators, engineers, contractors, and crews who have been working around the clock for months to find solutions, maintain service, and move these critical projects forward. Their efforts are helping create a path toward restoring normal operations for our community.🙌
