Successful oversight of complex water and wastewater networks demands an integrated economic approach that aligns operational and engineering intricacies with financial, regulatory, and governance imperatives.

Gravelroad specialises in translating the operational reality of water infrastructure into robust, defensible economic and financial frameworks.

We leverage deep expertise in network economics and regulation to provide the clarity required by management and governance teams. Our core capability is in developing enduring, decision-ready economic models and Treasury frameworks for the water sector, ensuring that financial logic is prepared for both regulatory scrutiny and to inform operative strategic decision-making.

Our methodology is rooted in bottom-up engineering economics, focusing on identifying the underlying cause-and-effect relationships that drive network costs, value, and asset failure. This approach enables us to move beyond high-level costing to provide actionable metrics, such as unused capacity costs or the true financial liability of an asset backlog, required to objectively measure efficiency, substantiate regulatory forecasts, and strengthen sustained investment decision-making.

A key part of managing water infrastructure networks is the ability to collect useful asset condition data. The implementation of comprehensive condition assessment programmes informs evidence-based asset renewals. Very high criticality assets are crucial assets (such as treatment plants, pumps, major pipes and reservoirs) which create unacceptable consequences to communities and the environment should they fail. Understanding their actual condition and implementing prioritised renewals can reduce the risk and consequences of unexpected failures.

Gravelroad delivers actionable advisory services necessary for water entity success: from addressing the economics of asset sustainability through to securing financial integrity via credit rating protection and establishing a compliant, high-performing internal Treasury function. We deliver the niche financial and governance skills essential for the success of Water Services Delivery Organisations, including:

• Establishing the true, long-run marginal cost of service delivery, including capital replacement liabilities.
• Rigorous assessment of capital prioritisation, focusing on highest-value projects that improve network capacity and reduce failure rates.
• Navigating the regulatory environment in determining customer-centric and transparent service delivery to consumers
• Translating high operational costs, such as fault rates, into an economic view that demonstrates how they consume capital renewal budgets.
• Advising on the debt-to-revenue resilience strategy required to mitigate the impact of parental guarantees and secure an optimal credit rating.
• Acting as the “sophisticated representative” to negotiate bespoke covenant arrangements and secure favourable commercial terms for funding.
• Developing robust methodologies for regulatory compliance, product pricing, and cost optimisation that stand up to regulatory scrutiny.
• Drafting the Liability Management Policy (LMP) and Investment Policy to ensure they are robust, fully compliant, and align with the Board’s defined Risk Appetite.
• Quantifying the societal and economic costs of natural disaster risk (e.g., earthquake, flood) to justify strategic investment in resilient infrastructure.
