US Market. No publisher influence. > **Key Insight:** HydroSewer - Drainage Network is a utilities app by Transparent Blue Water LLC. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Utilities | | **Developer** | Transparent Blue Water LLC | | **Pricing** | Freemium | | **Platforms** | iOS & Android | | **Confidence** | Low (0.3/1.0) | | **Data Age** | 55d | ## Metadata & Market Performance - **Publisher:** Transparent Blue Water LLC - **Category:** Utilities - **Target Audience:** Civil engineers, hydraulic modelers, and field technicians. - **Platforms:** iOS & Android - **Version Reviewed:** 1.10.1 - **Report Date:** 2026-09-12 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.3/1.0) - **App Store ID (iOS):** 6754671899 - **Bundle ID:** com.transparentbluewater.hydrosewer - **Google Play ID:** com.transparentbluewater.hydrosewer - **Data Window:** Analysis based on signals collected up to 2026-09-12 ## Executive Snapshot **What it is:** HydroSewer is a professional stormwater and sewer network analysis tool for iOS and iPadOS that runs EPA SWMM 5.2 simulations locally. **Why users hire it:** It replaces manual paper-based field notes and desktop-only simulation cycles with a mobile-first workflow, removing the friction of syncing site observations with hydraulic models. ## App DNA (Features & Intent) - **[Differentiator] EPA SWMM 5.2 Simulation Engine:** Runs hydraulic simulations locally on-device using the industry-standard EPA SWMM 5.2 engine without cloud dependency * *User Intent:* Users expect seamless access across multiple devices. - **[Differentiator] Field Notes and Photo Attachments:** Allows users to pin notes and photos to specific manholes, outfalls, or pipes on an interactive map - **[Standard] Shareable PDF Reporting:** Generates a PDF report of open field notes for distribution to team members or clients * *User Intent:* Users seek social connection and competitive engagement with peers. ## Market Position {#market-position} HydroSewer targets the professional Utilities segment with a specialized mobile-first simulation tool. The absence of direct mobile-native competitors in the EPA SWMM space provides a temporary advantage in establishing a field-to-office workflow standard. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free tier with unlimited network modeling and field notes, HydroSewer Pro one-time purchase for PDF report generation - **Analysis:** The one-time purchase for reporting serves as a conversion lever for professional users while maintaining free access to core simulation tools to build a user base. ## SWOT Analysis {#swot} **Core Strengths:** - On-device EPA SWMM 5.2 engine removes connectivity dependencies - Interactive map-based field notes create persistent project-specific data layers **Growth Levers:** - Automated as-built discrepancy flagging could deepen field-to-office workflow integration ## What's New - **Latest (v1.10.0, 1 months ago):** Introduced map-based visualization for notes, PDF report sharing, and project management tools including saved projects and HydroSewer Pro integration. ## App Momentum (Maintenance) {#momentum} - Shipped field notes and photo attachments. - Enabled PDF report generation for Pro. - Ships ~7-8 week maintenance cadence. > **Cadence:** 2 total versions · 2 majors in last 6 months · 48 days since last update · 7 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} HydroSewer - Drainage Network is an utilities app that is free with in-app purchases. > **Bottom Line:** HydroSewer's on-device simulation engine provides a clear technical advantage for field engineers, but the lack of user-generated social proof remains a barrier to professional adoption. Focusing on onboarding will help convert initial downloads into active, long-term users. **Best for:** Civil engineers, hydraulic modelers, and field technicians. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship in-app tutorial for EPA SWMM file imports because zero ratings suggest high barrier to entry for new users → increase conversion ### Outlook: Stable The market for mobile hydraulic modeling is currently underserved, leaving HydroSewer in a strong position to define the standard for field-to-office workflows. Continued investment in professional reporting features will be necessary to justify the Pro purchase as the user base grows. - 🟢 The latest release adds field notes and photo attachments, showing active investment in the field-to-office workflow rather than maintenance-only updates. - ⚪ The current 7-8 week update cadence indicates a steady development pace, which is sufficient for a specialized professional tool. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **HydroSewer - Drainage Network** (this app) | N/A/5 | N/A | Transparent Blue Water LLC | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.8/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.4/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** Transparent Blue Water LLC - **Website:** [https://transparent-blue.com](https://transparent-blue.com) - **Social:** [X/Twitter](https://twitter.com/transparentb) · [YouTube](https://www.youtube.com/@transparentbluewater) · [LinkedIn](https://www.linkedin.com/company/transparentbluewater) ## Data Sources & Links - **App Store ID:** 6754671899 - **Google Play ID:** com.transparentbluewater.hydrosewer - **Dev Site:** [Official Website](https://transparent-blue.com) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.4/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*VPN 365-Master WIFI Security*](https://marlvel.ai/apps/vpn-365-master-wifi-security) (vpn fast) · 4.6/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating ## Frequently Asked Questions {#faq} ### Is HydroSewer compatible with standard EPA SWMM files?
