Dear Wellington Water Limited,

Please provide all information relating to contracts to supply connectivity to WW sites and infrastructure. The includes internal communications, water meters, sensors, pumping and treatment sites, and storage facilities.
Include information relating to cost/spend, comms network maps and service providers.

Yours faithfully,

Sam Brown

Dear Wellington Water,

Thank you for seeking clarification. Please find my refined request below:

1. Timeframe: Current contracts and arrangements as of December 2025, plus any contracts entered into or renewed within the last 3 years (2022-2025).

2. Scope of assets: All operational water and wastewater infrastructure that requires telecommunications/data connectivity for operational purposes, including but not limited to:
- SCADA systems at treatment plants and pumping stations
- Remote monitoring equipment at storage facilities
- Water meters with telemetry capability
- Sensors and IoT devices for network monitoring

I do not require information about office buildings or general IT infrastructure.

3. Level of detail - Internal communications: I do NOT seek internal emails or Teams messages. I seek:
- Copies of contracts or summaries of contractual arrangements with connectivity providers
- Service specifications (bandwidth, technology type, service levels)
- Annual expenditure on connectivity services by provider
- Contract terms including duration and renewal dates

4. Network maps/topology: I seek information sufficient to understand the general architecture and organisation of Wellington Water's operational communications network, such as:
- Network topology diagrams showing how sites connect (e.g., star topology to central hubs, mesh networks, point-to-point links)
- Whether sites connect directly to internet/providers or route through WW-controlled infrastructure
- Primary and backup connectivity paths for critical sites
- Geographic organisation (e.g., "Northern network served by Provider X, Southern by Provider Y")
- Technology types used for different site categories (e.g., "treatment plants: fibre, remote pump stations: 4G cellular, valley sites: point-to-point wireless")

I do NOT require:
- Specific IP addresses, VLANs, or network addressing schemes
- Equipment make/model or firmware versions
- Authentication credentials or security configurations
- Precise GPS coordinates or detailed site layouts
- Information that would facilitate unauthorised access

I am seeking to understand the logical organisation and resilience of the network, not technical specifications that would create security risks.

5. Priority areas: If providing complete information would be overly burdensome, please prioritise:
- Treatment plants and major pumping stations (highest priority)
- Remote sites currently served by wireless/satellite connectivity
- Any sites where connectivity arrangements changed in the last 3 years

I am seeking to understand what connectivity solutions Wellington Water uses for operational infrastructure, who provides them, and at what cost. This is public interest information about essential services infrastructure.

Yours sincerely,

Sam Brown
