Tirta — Water Utility Management System
PT. Kaltim Industrial Estate
2025
Project Overview
Tirta is the water utility backbone for PT Kaltim Industrial Estate's tenant base — replacing manual meter reading and billing with a connected system spanning a customer-facing mobile app and an internal operations dashboard. It manages customer accounts, water packages, meter readings, billing cycles, payments, and complaint handling in one place, with WhatsApp notifications keeping tenants informed without needing to check a portal.
The Challenge
Water billing and meter tracking for a large industrial estate tenant base was scattered across manual records, making it hard to catch billing errors or track payment status at a glance
Tenant complaints (leaks, meter issues, billing disputes) had no structured intake or tracking process
No proactive way to notify tenants about bills, payments due, or service updates
Our Solution
We built a two-sided system: a tenant-facing mobile app for account and payment visibility, and an internal web dashboard for KIE's operations team to manage the full water utility lifecycle.
Centralized customer and worker management with role-based access control
Digitized water meter reading and package/tariff management
End-to-end billing: bill generation, payment recap, pending-bill tracking
Structured complaint intake and resolution tracking
WhatsApp Gateway integration for automated tenant notifications
Configurable system settings so KIE's team can adjust tariffs/packages without a code change
Key Feature
The platform includes a comprehensive set of capabilities designed to improve efficiency and user productivity.
Customer & worker account management with roles/permissions
Water meter reading & package configuration
Automated billing, payment recap, and bill-pending dashboards
Complaint management module
WhatsApp notification gateway
Job/work order tracking for field technicians

Business Impact
By combining strategic planning with modern technology, this project delivered measurable improvements across the organization's daily operations.
Centralized, auditable record of every tenant's water usage and billing history
Faster complaint resolution with a structured intake process instead of ad-hoc reports
Reduced manual reconciliation work for the finance/ops team through automated billing recap
Tenants get proactive WhatsApp updates instead of having to chase status themselves
"Before Tirta, tracking who'd paid and who hadn't meant digging through spreadsheets. Now it's a two-minute check."
