Portable Water Pressure Solution
LazerTrailer Unit No.1 was deployed at Brimham Rocks Road, Harrogate, to address low water pressure affecting 11 properties after a local rezone. Pressures were below 0.8 bar, and the goal was to boost this to 2.0 bar, ensuring a minimum stator pressure of 1.5 bar. The unit was designed to provide restorage via a tanker and operate at full pumping capacity for at least 12 hours.
The unit arrived on 8th August for initial testing. While the inlet and outlet connections were London Fire Brigade threads, 2½” instantaneous connections were deemed more suitable. Adapters were prepared for full deployment on 14th August. On deployment day, the system was configured and fine-tuned, with live monitoring of battery levels and power output enabled.
On 14th August, the LazerTrailer was deployed over an OXO with valves closed and washout hydrants on either side. The upstream pressure of around 0.8 bar confirmed the low-pressure issue. The unit successfully boosted the outlet to 2.0 bar, improving customer supply. After two days, by 16th August, the system was performing well, with peak usage at 0.35 kWh and 1.3 kWh contribution from solar input, showing the benefit of integrated renewable support.
By 18th August, after four days of deployment, total energy use reached 15.7 kWh, supplemented by 3.8 kWh from solar. Initial battery readings of 45.9% reflected first-time calibration, common with Lithium Polymer systems.
The unit was removed from service on 19th August for charging. A standard 13-amp plug enabled overnight charging, reaching full capacity in approximately 14 hours. Minor calibration was planned to ensure digital readouts matched visible battery data, typical for first-time use.
