Water Utility Meter Reading and Billing Software: Dublin 2026

The verdict in three sentences

A water operator with 32,000 connections replacing its billing package should not buy everything in one block: the billing core, automated meter reading, leak allowances, the customer portal and field work orders carry different risks and prices. Full public tenders run from 150,000 to 350,000 EUR excl. VAT with a 8 to 12 month timeline. Smart lotting lets you hand the differentiating pieces, such as the customer portal or the field app, to a custom build of 3,810 to 22,870+ EUR, with the rest quoted separately.

The scope of a 32,000-connection operator

The operator, which serves business customers and group water schemes alongside Uisce Éireann's national network, runs two billing cycles a year, a growing share of monthly instalment plans, and 12,000 of its 32,000 meters already read remotely. The current package does not handle leak allowances cleanly, so claims are processed by hand.

Moving from 70 % to 35 % paper bills over two annual cycles saves about 20,000 EUR a year in postage and printing on its own.

Lotting the tender: who does what, for what budget

Kolonell works on the lots where user experience and speed matter most: a modern customer portal and a field app start at 3,810 EUR for a simple scope and reach 22,870+ EUR for a full portal connected to the billing core via API. Vendor lots and data migration are quoted separately based on the chosen architecture.

Leak allowances: what the software must automate

Whether the rule comes from your own tariff policy or mirrors Uisce Éireann's approach for non-domestic customers, the logic is similar: when consumption spikes because of a leak on the customer side, the customer reports a repair within a set deadline and part of the excess volume is waived. The software must detect the abnormal increase, notify the customer, receive the repair evidence through the portal, compute the allowance and issue the corrected bill. With smart reading, detection moves from once per cycle to near-daily alerts, which sharply reduces lost volumes and disputes.

Mini case study

Aoife, director of a 32,000-connection water operator near Dublin, compares two scenarios. A single-vendor tender is estimated at 310,000 EUR excl. VAT. By lotting, she picks a billing core at 170,000 EUR, meter reading at 35,000 EUR, migration at 22,000 EUR and gives the portal and field app to Kolonell for 34,000 EUR in total, so 261,000 EUR excl. VAT. The 49,000 EUR saving comes on top of the 20,000 EUR a year saved on postage, with a mobile-friendly portal from day one.

FAQ

Can a custom portal plug into a vendor billing package?

Yes, if the tender requires a documented API for accounts, bills and payments. The connector usually accounts for 15 to 25 % of the portal budget.

What timeline should we plan for the full project?

Allow 8 to 12 months from contract award to cutover, including 2 to 3 months of migration and parallel running. The portal can ship in 3 to 4 months in parallel.

Can leak allowances be fully automated?

The calculation and corrected bill can, while validating the repair evidence stays human. Handling time drops from about 45 minutes to under 10 minutes per case.

Where is the system hosted?

In an EU data centre, GDPR compliant, with daily backups. Hosting typically adds 150 to 600 EUR a month depending on the service level.

Which online payment methods fit?

Card payments and SEPA direct debit through a regulated payment provider, which also supports instalment plans. Integration into the portal usually takes 1 to 2 weeks.
