SiteNet is designed for construction sites, developers, contractors and facilities managers who need reliable water leak detection and automatic protection.
Water leaks on construction sites can cause expensive damage, project delays and safety issues. SiteNet helps prevent loss, protect assets and reduce downtime.
SiteNet is pre-wired, making installation fast and simple. It integrates LeakNet flow-based leak detection and cellular 4G gateway into a weatherproof enclosure.

SiteNet is supplied with a 110 V site-ready power supply, matching the temporary power arrangements found on construction and refurbishment projects.
Why it matters: mains power on active sites is often provisional, shared, or unavailable during early phases. A device designed for site power avoids costly transformer work, reduces install delays, and keeps leak protection live while the build progresses, when escape-of-water risk is often highest.
This is a core capability of SiteNet for Construction, Quensus's plug-and-play solution for protecting construction sites under schemes such as CIRIEG guidance.
SiteNet maintains leak protection for up to 24 hours on battery backup when mains power is lost on site.
Why it matters: power cuts on construction projects are common and often coincide with reduced staffing. Continuous protection through outages prevents the scenario where a leak runs unchecked exactly when nobody is watching.
A defining capability of SiteNet for Construction, aligned with temporary site safety requirements.
SiteNet ships pre-cabled and ready for deployment, minimising on-site wiring and commissioning time.
Why it matters: construction programmes are measured in days, not weeks. Plug-and-play setup means protection can be live before permanent plumbing is complete, reducing exposure during the phase insurers and project managers worry about most.
Standard on SiteNet for Construction, designed for rapid deployment and relocation as the site evolves.
An IP68-rated outdoor enclosure protects hardware from rain, dust, and temperature swings on external or semi-exposed installs.
Why it matters: water infrastructure often lives outside the conditioned core of a building. Weatherproofing reduces failure rates, extends service life, and avoids the false sense of security that comes from equipment that only works in perfect conditions.
Standard on SiteNet for Construction and LeakNet LP Data Logger for yards, plant enclosures, and external meter chambers.
Industrial-grade cellular connectivity (GPRS/GSM) transmits alerts and usage data where fixed broadband is unavailable or unreliable.
Why it matters: construction sites, remote assets, and early-phase builds rarely have stable LAN infrastructure. Cellular backhaul keeps monitoring live from day one, so teams are notified during the highest-risk periods instead of after permanent comms are installed.
Built into SiteNet for Construction and LeakNet LP Data Logger for dependable reporting without dependency on site WiFi.
An on-device audible alarm provides a local alert when a leak or fault condition is detected, complementing remote notifications.
Why it matters: remote alerts depend on connectivity. On-site staff, security teams, and contractors still need an immediate signal when the network is down or phones are unattended. Audible alarms also support accreditation requirements (including BREEAM WAT03) where local indication is specified alongside automated detection.
Built into LeakNet Gen2 and SiteNet for Construction, so protection remains visible on the ground as well as in FlowReporter.
Quensus devices integrate with existing Building Management Systems (BMS), feeding alarms and status into the platform facilities teams already monitor.
Why it matters: duplicate dashboards get ignored. BMS integration puts water events alongside HVAC, access, and fire signals, improving escalation paths and supporting estates that require centralised alarm management, even when cloud connectivity is limited.
Supported on LeakNet Gen2, Flow Sensors & Meters, SiteNet for Construction, and Valves.
Quensus flow-based devices accommodate pipe sizes up to 8″, so a single monitoring approach can cover mains supplies across commercial, industrial, and multi-occupancy buildings without forcing a downgrade in measurement quality.
Why it matters: estates often mix pipe diameters between plant rooms, risers, and tenant supplies. A platform that scales with pipe size reduces bespoke engineering, speeds specification, and keeps leak thresholds meaningful on high-volume lines where small percentage losses still mean large volumes of water.
Available on LeakNet Gen2, LeakNet Gen1, Flow Sensors & Meters, LeakNet LP Data Logger, SiteNet for Construction, and Valves. The same capability supports everything from permanent building installs to temporary site protection.
Alerts can be sent to multiple stakeholders simultaneously: facilities, security, contractors, and estate managers, so the right people respond without single-point dependency.
Why it matters: water events do not respect org charts. Multi-recipient alerting reduces delay when the primary contact is off-site and creates an auditable chain of notification for insurers and compliance reviews.
Available across Leak Cable, Splash Sensors, LeakNet LP Data Logger, and SiteNet for Construction.
Authorised users can shut off water remotely from FlowReporter when a leak is confirmed, from a phone, tablet, or desktop.
Why it matters: not every alert should auto-shut (think fire sprinkler supplies), but when human verification arrives, remote shut-off converts insight into action immediately. That reduces average loss per incident and supports lone-worker safety on large estates.
Works with Leak Cable, Splash Sensors, and SiteNet for Construction via the FlowReporter App.
Sprinkler override keeps the valve open while the fire sprinkler system demands water, preventing automatic shut-off from compromising life safety.
Why it matters: combined supplies need intelligent logic, not blunt isolation. Safety-critical override ensures leak protection coexists with sprinkler operation, a requirement insurers and fire engineers scrutinise on shared incoming mains.
Built into LeakNet Gen2 and SiteNet for Construction where fire and domestic supplies share infrastructure.
Instant notifications via SMS, email, and the FlowReporter mobile app keep teams informed wherever they are working.
Why it matters: different roles live on different channels. Multi-channel alerting maximises the chance someone actionable sees the event within minutes, which is critical when average escape-of-water claims run to thousands of pounds per hour of unchecked flow.
Standard across LeakNet Gen2, LeakNet Gen1, Flow Sensors & Meters, LeakNet LP Data Logger, and SiteNet for Construction.
Leak Cable is flexible and easy to route through plant rooms, under equipment, and along corridors, following the path water would take if a leak occurred.
Why it matters: rigid detection layouts leave gaps. Manageable cable runs mean faster installs, simpler maintenance, and coverage shaped to the risk, not the other way around. That reduces project cost and improves the chance moisture is detected before it reaches critical assets.
Central to Leak Cable and also relevant to SiteNet for Construction deployments where temporary routing must adapt as the site layout changes.
