Residential Secondary Supply
Secondary-Supply Safety Monitoring at a Baoding Residential Pump Station
1 / 4Project Background
A residential community in Baoding relies on secondary supply — storage tanks and booster pumping — to serve its high-rise homes, a link where recontamination risk is highest and where hundreds of families' water safety is ultimately decided.
Customer Challenge
Secondary supply adds storage and pressurization after the municipal network, and water quality can degrade in tanks and pipes. Without online monitoring at the pump station, a quality problem would only surface at residents' taps.
The TENGINE Solution
A TMS-D3000 multi-parameter secondary-supply monitor was installed in the community's pump station, tracking turbidity, residual chlorine, pH and temperature continuously — a compact, wall-mounted unit that is essentially maintenance-free with electrode-based chlorine measurement.
Implementation
The analyzer was wall-mounted in the pump station and commissioned on the secondary-supply line, with data available to the property team around the clock.
Project Results
The community's secondary supply is now monitored in real time: any quality deviation is caught at the pump station before it reaches homes. The equipment runs stably with minimal upkeep, and residents' feedback has been thoroughly positive.
Related Case Studies
Conventional chlorine instruments need frequent electrolyte and DPD reagent replacement — unaffordable at this scale. Community pump rooms are cramped, and most devices on the market cannot measure stably down at the 0.05 mg/L national limit where secondary-supply compliance is actually judged.
At the network's far end inside the park, residual chlorine and turbidity readings run low — below the reliable range of ordinary instruments. The park needed monitoring accurate enough at low concentrations to prove its water was truly safe.
Zoned supply means small chlorine fluctuations at low range — demanding real measurement precision — while day-to-day operation falls to a property team without instrument specialists. Equipment had to be highly stable and low-maintenance, and installation had to work in a cramped underground pump house.
