An investment calculation is useful when its assumptions can be checked. For wastewater Web-SCADA and AI, separate initial investment, recurring costs and benefits demonstrated on the facility's own operating records.
List the complete project costs
Include equipment, integration, configuration, training and internal work. Record recurring software, connectivity, support and maintenance costs. Explain which items are quotations, estimates or already committed expenditure.
Build benefits from an operating baseline
Estimate benefits from documented energy, chemical use, manual work or avoidable downtime. Keep scope and periods consistent. Do not use a generic savings percentage as a measured result, and avoid counting the same benefit twice.
Distinguish ROI from simple payback
For a stated period, ROI can compare net benefit with investment cost. Simple payback divides initial investment by annual net benefit only when that benefit is positive and the assumptions fit. State the formula and treatment of recurring costs explicitly.
Compare assumptions and validate a pilot
Present conservative, reference and favourable assumptions rather than a single certain outcome. Identify the data needed to confirm each assumption. Compare actual costs and outcomes after the pilot and revise the case before expansion.
Records to check
| Record group | Evidence to review |
|---|---|
| Investment | One-off items and estimate status |
| Net benefit | Verified benefits less recurring costs |
| Review | Time period, assumptions and sensitivity |
Prepare an assessment with X-IRIS
Bring cost records, a proposed scope and the measurements that will confirm or reject the expected benefits. Review the implementation roadmap and request an assessment to agree a scope that can be tested.
