Welcome to Maintenance & Operations!

Our Maintenance and Buildings & Grounds teams are dedicated to providing a clean and safe learning environment for our students, as well as maintained facilities for all CVUSD staff and the public. We are responsible for maintaining more than 130 buildings and over 220 acres of grounds and athletic fields, and the daily and seasonal cleaning of all campuses and facilities district wide.

Natalie Hung is the friendly voice you will reach when contacting our department. She provides amazing support. Maintenance & Operations also assists with special events and provides support for many community groups who use our facilities daily. Please reach out to Katelyn Raymond with any facility use or rental questions or visit Facilitron.

Castro Valley is fortunate to have a transportation program that safely transports an average of 475 students to and from school each day. This includes Special Education. We also provide transportation for field trips and away games. Please visit the Transportation Department for more information.

Castro Valley Unified School District Water Testing Program & Protocol

The Castro Valley Unified School District (CVUSD) maintains a proactive water testing and safety program to ensure all drinking water across district facilities meets or exceeds federal and state safety standards. This document outlines the regulatory requirements, district sampling procedures, remediation steps for addressing deficiencies, the ongoing expansion of filtered bottle filling stations, and regional water quality information.

1. Regulatory Requirements & Water Testing Standards

• Mandated Testing Scope: CVUSD routinely tests drinking fountains, bottle filling stations across district school sites. While state law requires testing at only a small sample of outlets (1 to 5 per site), the district routinely conducts testing across drinking sources districtwide to ensure comprehensive safety.
• Actionable Threshold: Water quality safety standards define an actionable lead level as anything at or above 15 parts per billion (ppb). Any fixture meeting or exceeding this threshold requires immediate remediation before it can be restored to service.
• Sampling Methodology: Testing utilizes both pre-flush (first-draw) and post-flush sampling to determine whether elevated levels stem from localized fixtures or broader plumbing infrastructure.

2. District Water Testing Process

1. Scheduled Sampling: Water samples are collected from drinking fountains, faucets, and hydration stations across district sites during routine testing rotations.
2. Laboratory Analysis: Samples undergo certified laboratory analysis to measure lead concentration in parts per billion (ppb).
3. Results Assessment: Maintenance & Operations personnel review lab results immediately to identify any fixture exceeding the 15 ppb actionable limit.

3. Addressing Deficiencies & Corrective Action Protocol

When a fixture tests at or above the actionable level of 15 ppb, CVUSD executes the following standardized remediation protocol:

1. Immediate Isolation: The affected fixture is immediately taken out of service by shutting off its local water supply valve, preventing student and staff access. Site administration is notified right away.
2. Component Replacement: Maintenance staff replace the non-compliant fixture along with associated angle stops, supply lines, and plumbing fittings.
3. System Flushing: The newly installed fixture and connecting lines are thoroughly flushed to remove potential particulates and clear the plumbing lines.
4. Retesting & Re-commissioning: Mandatory follow-up sampling is performed. The fixture remains offline until certified lab results confirm water quality is below actionable levels.
5. Permanent Decommissioning: Any units that still fail to meet safety standards after these measures are implemented are permanently decommissioned or removed from the site.

4. Expansion of Filtered Bottle Filling Stations

• District Initiative: Over the last several years, CVUSD has maintained a concerted effort to install filtered bottle filling stations across all campuses.
• Current Progress: By installing multiple units each year, the district has successfully added over 50 filtered bottle filling stations districtwide to date.
• Ongoing Commitment: Additional bottle filling stations are actively scheduled for installation in the coming months as part of an ongoing commitment to expand access to clean, filtered drinking water for all students and staff.

5. Regional Water Quality Information

• Water Provider: The district receives its water supply from the East Bay Municipal Utility District (EBMUD).
• Public Reports: Detailed information regarding regional water treatment, testing, and safety reports can be reviewed directly on the EBMUD Water Quality Webpage.
