Message from the Board Chair
As we close out another year at Triunfo Water & Sanitation District, I want to take a moment to reflect on our progress, recognize the dedication of our staff, and look ahead to a strong and resilient future for our community. This year marks the end of TWSD’s 62nd year of service, a milestone that speaks to decades of commitment to providing reliable water and sanitation services to the customers we proudly serve.
One of the most significant accomplishments of the year came on December 8, when the Las Virgenes-Triunfo Joint Powers Authority unanimously approved a contract amendment with Walsh Construction, officially launching construction of the Pure Water Project’s Advanced Water Purification Facility. This milestone represents a major step forward in strengthening our region’s water supply by providing a local, sustainable, and safe drinking water source. Through this partnership, the JPA is investing in infrastructure that will enhance long-term reliability, protect public health, and benefit our communities for decades to come.
Equally important is the day-to-day service our customers rely on, and I am proud of the excellent work performed by our customer service team. Their professionalism and responsiveness remain a cornerstone of TWSD’s operations. To further enhance the customer experience, a new and upgraded customer payment portal will be launched at the end of January, offering improved functionality and convenience.
I am also pleased to share that TWSD once again received the Government Finance Officers Association Award for Excellence in Financial Reporting. This recognition reflects our staff’s continued commitment to transparency, accountability, and sound financial management. Across all departments, our employees work tirelessly to maintain high standards and ensure the District remains well positioned to meet both current and future needs.
As I conclude my service as Board Chair, I want to thank my fellow Board members, our outstanding staff, our partners, and our customers for their trust and support. It has been an honor to serve this District during such a pivotal time, and I am confident that TWSD will continue to make meaningful strides in securing a reliable and resilient water future.
On behalf of the Board of Directors, I wish you and your families a safe, healthy, and happy new year.
Sincerely,
Leon Shapiro
2025 Chair

PURE WATER PROJECT: MAJOR MILESTONES IN 2025
Building on a partnership that began in 1964, the Las Virgenes-Triunfo Joint Powers Authority (JPA)’s Pure Water Project continues to advance a more sustainable and locally reliable water supply.
In 2025, the project reached major milestones with the start of construction on the Advanced Water Purification Facility (AWPF) and expanded outreach to keep community stakeholders informed and engaged. These achievements mark significant progress toward delivering environmentally responsible Pure Water to the region.
MAY: Pure Water Coffee Tasting at Cafe Sapientia in Oak Park. Families enjoyed giveaways, entertainment, and delicious sips of coffee and tea made with our PURE water.
AUGUST: First informational session for the public kicked off. Community members in Agoura Hills learned about the planned construction process and information about oak tree removal and mitigation efforts associated with the AWPF.

OAK PARK MIDDLE SCHOOL STUDENTS’ ARTWORK FEATURED IN 2025 MWD CALENDAR
Artwork by 13-year-old Micah Aliling, a 7th grader at Medea Creek Middle School in Oak Park, was selected by the Metropolitan Water District of Southern California (MWD) to appear in its printed 2026 Water Calendar and digital library.
“The phrase ‘Save Water, Save Life’ means that conserving water protects all living things on Earth,” says Micah. “When we use water wisely, we can ensure a cleaner, brighter, and healthier future.”
This marks the fourth consecutive year that a student from Oak Park has had their artwork featured in the calendar. READ MORE
