<p><strong><span class="lead-1">Assess Real-time Impact of Operational Decisions on Receiving Waters</span></strong></p>
<p>Water utilities frequently face the complex challenge of identifying and quantifying the precise sources contributing to water quality degradation in receiving waters.</p>
<p> </p>
<p>DHI CityFlow Live Receiving Water is a decision intelligence platform that provides a map-based virtual twin to simulate and analyse the impact of various discharges on receiving waters. This platform uses physics-based models, rather than purely data-driven approaches, to offer scientifically justifiable and accurate simulations across diverse environmental conditions. </p>
<p> </p>
<p>Users gain a comprehensive understanding of pollution pathways, enabling targeted mitigation strategies and informed investment decisions to improve waterway health and avoid regulatory fines. The system integrates into broader urban water management workflows, providing actionable insights for strategic planning, operational optimisation, and stakeholder communication.</p>

<p class="text-sm leading-normal m-0 font-sans" data-pm-slice="1 1 []"><em>See exactly who contributes what, where, and when. </em>The module supports utilities to move from symptom spotting to source attribution. It provides cumulative impacts of loads from outfalls, creeks, and non-point sources. It maps individual and cumulative footprints, exceedance areas, and profile variations along with automated reports.</p>

<p class="text-sm leading-normal m-0 font-sans" data-pm-slice="1 1 []"><em>Know your compliance exposure before it becomes a breach. </em>Track hourly to weekly to monthly to annual impact, compute exceedance areas in zones that matter, and compare scenarios to demonstrate risk reduction or improvement. Test bypass and overflow options so operational changes are safe, defensible, and regulator‑ready.</p>

<p><em>Turn hydrology, hydraulics, and hydrodynamics into visuals everyone understands. </em>Designed to transform complex aquatic ecosystem data into intuitive visualisations and automated reports. It generates graphic-rich analytics and infographics that can be readily shared with regulators, managers, and the public. DHI firmly believe that this democratation of scientific understanding, reduces reliance on consultants, and supports transparent decision-making for all stakeholders.</p>

<p class="text-sm leading-normal m-0 font-sans" data-pm-slice="1 1 []">Run models in a secure, cloud‑based, and multi‑user workspace. Cut rework and uncertainty so you can prioritise upgrades and operations that deliver measurable benefits and the best return on every dollar.</p>

How does the Receiving water module help?

<p class="whitespace-normal break-words"><strong>Diagnose I&amp;I problems and prioritise network improvements</strong></p>
<p class="whitespace-normal break-words">&nbsp;</p>
<p class="whitespace-normal break-words">Identify and quantify infiltration and inflow (I&amp;I) problems across your network. The Data module analyses system data to show where issues exist and how severe they are, helping you prioritise actions like disconnecting improper connections or targeting pipe rehabilitation. It provides the diagnostic foundation that supports all other modules.</p>

Data

<p class="whitespace-normal break-words"><strong>Prioritise investments and model future system performance</strong></p>
<p class="whitespace-normal break-words">&nbsp;</p>
<p>Determine where to invest rehabilitation budgets for maximum impact. The Planning module enables cost-benefit analysis to identify high-value projects and prioritise system improvements. You can also model future scenarios, population growth, urban expansion, climate changes, to understand how your system will perform over time without intervention.</p>

Real-Time

<p class="whitespace-normal break-words"><strong>Predict incoming flows and prepare operations in advance</strong></p>
<p class="whitespace-normal break-words">&nbsp;</p>
<p class="whitespace-normal break-words">Get advance warning of incoming flows to your treatment plant. The Forecast module predicts inflow conditions hours or days ahead, giving operators time to prepare for events. It's particularly valuable for utilities with underutilised storage capacity or infrastructure, helping identify opportunities for better system utilisation through real-time control.</p>
