Then / The old way
Spreadsheets, Information Silos & Audit Anxiety
Most plants still run on a patchwork of Excel files, paper logs and long email chains. When your data lives in a dozen places, decisions slow down, small changes in a reading slip past unnoticed, and an unannounced EPA visit on the day your key operator is on holiday turns into a scramble.

Now / The Neptune way

Neptune brings it all together in one bespoke cloud-based platform, set up around your own tanks, sensors and lab parameters. Enter a reading once and Neptune does the calculations, shows your custom trends, flags anything off target against your ELVs and produces an EPA ready report in one click.

FAQ
Who is Neptune for?
Neptune is designed with waste water treatment plants and industrial sites in mind, suitable for everyone from operators and environmental staff to plant managers. Each person gets their own access and custom dashboards, showing exactly what they need to see.
How does Neptune help during unannounced EPA audits?
Roughly 6% of EPA non-compliance fines stem from reporting failures and disorganised records rather than treatment failure. Neptune provides continuous, timestamped evidence of process control, a core EPA requirement. Every daily log, breach acknowledgement, lab certificate and licence document is stored in a searchable Document Vault, ready to pull up in seconds.
How long does it take to transition from Excel, and do our operators need training?
Our Cork based team handles the entire transition, both online and on-site. We aim to complete the data transfer within the first month. Because Neptune has an intuitive interface, role based views and built-in self coaching workflows, operators need no expensive software training, and routine data entry time drops by an average of 68.4%.
How is our facility’s operational and compliance data secured?
Neptune runs as a standalone web application hosted on enterprise grade AWS cloud infrastructure. All plant data is encrypted both in transit and at rest, with strictly isolated databases that have no public internet access and granular role based permissions for your staff.
