“…SWUs create enterprise funds that allow municipalities to establish a dedicated and predictable revenue source for proactive SWM services (US EPA, 2008). Among the financial advantages, McDonald and Naughton (2019) find SWUs to be an effective means for increasing per capita funds for stormwater services compared to municipalities without SWUs. In addition, stormwater fees are increasingly advantageous as a direct funding source for climate change adaptation efforts, especially in coastal cities facing rising sea‐level impacts (Bloetscher et al., 2011).…”

To confront the converging challenges of failing infrastructure, climate change, degraded water quality, and fewer undeveloped lands, many municipalities are establishing stormwater utilities (SWUs) to allocate a dedicated funding source to stormwater management (SWM) services. As a public service, creating a “fair” SWU by defining collective values that reflect community and municipal needs is crucial. However, the prevalent professional discourse surrounding SWUs often conflates “equity” with “economic efficiency” when they are two theoretically separate concepts, which obscure concerns raised by service beneficiaries. This paper unpacks ideas of fairness based on a systematic literature review that frames SWM financing in terms of economic efficiency and SWM services in terms of distributional, procedural, and structural equity. The distinction of which is important to set appropriate expectations between SWUs and beneficiaries.

“…Nonetheless, planning an efficient UDS can be tricky as various cities do not have sufficient resources for stormwater management improvements and may not have the capital to address all regulatory requirements. As municipalities often work under budgetary limitations, they must allocate their resources wisely and make decisions to find the optimal tradeoff between the service objectives and the life cycle costs (LCC) [12,13].…”

“…For hydraulic optimization, the results of the AD index (from Table 4) were used as the initial solution for the SA. This means that the maximum diameter (D max ) was assigned for each pipe as the diameter suggested by the ADI, as presented in Equation (13). For example, if the total impervious area connected to a particular pipe in the network is 60 ha, the D max from Table 3…”

Structural resilience describes urban drainage systems’ (UDSs) ability to minimize the frequency and magnitude of failure due to common structural issues such as pipe clogging and cracking or pump failure. Structural resilience is often neglected in the design of UDSs. The current literature supports structural decentralization as a way to introduce structural resilience into UDSs. Although there are promising methods in the literature for generating and optimizing decentralized separate stormwater collection systems, incorporating hydraulic simulations in unsteady flow, these approaches sometimes require high computational effort, especially for flat areas. This may hamper their integration into ordinary commercially designed UDS software due to their predominantly scientific purposes. As a response, this paper introduces simplified cost and structural resilience indices that can be used as heuristic parameters for optimizing the UDS layout. These indices only use graph connectivity information, which is computationally much less expensive than hydraulic simulation. The use of simplified objective functions significantly simplifies the feasible search space and reduces blind searches by optimization. To demonstrate the application and advantages of the proposed model, a real case study in the southwest city of Ahvaz, Iran was explored. The proposed framework was proven to be promising for reducing the computational effort and for delivering realistic cost-wise and resilient UDSs.
