Tel Aviv's Digital Archives Are Drowning in Duplicate Images — Here's What the Numbers Show

Tel Aviv's municipal digital infrastructure is carrying a heavier load than most residents realise. An internal review completed in June 2026 by the Tel Aviv-Yafo Municipality's Digital Transformation Unit found that duplicate images — identical or near-identical files stored multiple times across different departments — account for roughly 34 percent of total digital storage consumption across the city's networked servers. That figure, drawn from a scan of more than 1.2 million image files, has forced the city to confront an unglamorous but expensive problem buried inside its own systems.

The timing matters. Tel Aviv is midway through a five-year smart-city infrastructure upgrade, with NIS 280 million allocated through 2028 under the Digital Tel Aviv 2028 programme. City technology officers have been under pressure to show that legacy inefficiencies are being cleared before new platforms are bolted on top of them. Duplicate image sprawl — the result of years of departments saving, re-uploading, and cross-sharing files without a unified naming or deduplication protocol — is now a line item in that conversation.

What the Data Actually Shows

The June audit identified 412,000 confirmed duplicate image files across the municipality's servers, concentrated most heavily in three departments: urban planning, public communications, and parks and infrastructure. The planning department alone held 118,000 duplicate files, many of them aerial photographs of Florentin, the Port of Tel Aviv, and the Sarona development precinct, captured repeatedly during permit reviews and never purged. At an estimated storage cost of NIS 0.08 per gigabyte per month under the municipality's current cloud contract, the redundant files represent an avoidable monthly expense running into the tens of thousands of shekels.

The Digital Transformation Unit, based at the municipality's technology campus on Ibn Gabirol Street, has been piloting a deduplication tool called CleanStack — sourced from a Haifa-based software firm — since March 2026 across a subset of the parks department's image library. Early results from that pilot, covering 60,000 files, reduced storage volume by 41 percent within six weeks. If that ratio holds across the full database, the city could recover the equivalent of several hundred terabytes of usable storage without purchasing new infrastructure.

The problem is not unique to Tel Aviv's scale, but the city's rapid digitisation has made it acute faster than anticipated. Between 2020 and 2025, the volume of image files held by the municipality grew by 310 percent, driven by drone surveys of construction sites, CCTV archiving requirements, and the rollout of the DigiCity resident-services portal, which allows departments to attach photographs to planning complaints, noise violations, and permit applications filed through the platform. Each portal submission can generate between three and twelve image copies depending on which departments are copied into the workflow.

What Happens Next

The municipality is expected to extend the CleanStack pilot to the urban planning department by September 2026, with a full system rollout targeted for the first quarter of 2027. The Digital Transformation Unit has also recommended adopting a unified file-naming convention across all departments by the end of this calendar year — a structural fix that would prevent duplicate accumulation rather than simply clearing existing backlogs.

For residents and businesses dealing with the municipality through the DigiCity portal or at service centres in Ramat Aviv and the Neve Tzedek administrative annex, the practical effect of a successful cleanup would be faster document retrieval times and reduced latency on permit-status updates. City technology officers have estimated that image-search queries, currently taking an average of 4.2 seconds per request on the planning department's internal tools, could drop to under two seconds following full deduplication.

The harder challenge is cultural rather than technical. Duplicate files accumulate because departments operate in silos, and staff have no automated alert when uploading a file that already exists in the system. Fixing that requires not just software, but a change in how the municipality's 10,000-plus employees interact with shared digital infrastructure — a process that no single audit or pilot program can fully resolve on its own.
