How OS can help

Keep track of your underground utility assets

Maintain your water mains, sewers and underground pipes efficiently with location data. Quickly infer where a damaged water pipe is before sending an engineer out to fix it. Save you and your customer’s time and money in the long-term.

Manage your overground assets

Detailed, up-to-date mapping data can help you manage your overground water assets efficiently. Find the perfect location for deploying bowsers in the event of a water crisis. Realise the proximity of your water networks, pumping stations and treatment works to homes, communities, shopping centres and more.

Targeted customer billing

With our location data you can be confident that when you send a water or waste water bill to your customers, it reaches the right address first time.
