Smart Pre-treatment Equipment

Xihai Rainwater product center: rainwater harvesting modules, storage and infiltration facilities, treatment and reuse systems for sponge cities.

Installed at the inlet of the harvesting line. A rain sensor watches the rainfall signal: the dirty first flush is discharged to the municipal drain, then the device automatically switches to collect clean rainwater — screening, first-flush diversion and flow splitting in one unit.
HDPE shell, stainless support frame, dedicated filter bag and level sensor. Works on hydraulic principle with no electricity; direct burial, corrosion- and ageing-resistant, flexible sealed connection to plastic pipework.
