San Juan City Mayor Francis Zamora on Tuesday, June 17, officially launched the city's Do-It-Yourself Water Catchment System Contest aimed at promoting water conservation and environmental sustainability among San Juaneños.
The contest, which is part of the 18th Cityhood Anniversary celebrations of San Juan, is a major project of the City Environment and Natural Resources Office (CENRO).  Households, businesses, and government institutions are urged to showcase their innovative solutions and ideas on practical water conservation and create their very own functional water catchment systems.
For households, participants must coordinate and register with their respective barangays and will be given one month to build their DIY water catchment system.
Each barangay will nominate its top 3 household finalists within two months from the launch date, based on the following criteria:
Design (50 percent) – use of recycled/reusable materials
Sustainability (25 percent) – potential for replication
Effectiveness (25 percent) – water collected, storage, and usability
These top 3 household finalists per barangay will be monitored by CENRO from August 2025 to February 2026.
Meanwhile, business establishments and government institutions participants have until August 1 to construct their systems, ensuring they match the water requirements and infrastructure of their buildings. Entries will be judged using the following criteria:
Functionality/Efficiency (25 percent) – water collected and storage
Usability (25 percent) – actual use of collected water
Creativity & Cost-effectiveness (20 percent) – recycled/affordable materials
Sustainability (20 percent) – low maintenance, scalable
Community Impact (10 percent) – outreach or water-sharing
Household, business establishment, and government institution entries must also be posted on Facebook, Instagram, or TikTok with the hashtag #SaveWater4MakabagongSanJuan, along with a short caption on water conservation. Participants are required to submit a report detailing the design, materials used, cost, and water savings, Zamora said.
