Store. Distribute. Meter & bill.
One complete piped-LPG utility for residential estates — engineered to European gas-utility practice and adapted to Kenyan regulation.
Bulk storage · Metered supply · Automatic M-Pesa billing — piped safely to every apartment.
Bulk storage & tank yard
A single 5-tonne LPG vessel in a secured, fire-protected yard supplies the whole estate — no cylinders, no per-unit refills.
- Manual isolation valve and emergency solenoid wired to the estate ESD panel.
- Pressure relief valve piped to a vertical vent stack, clear of openings.
- Excess-flow valve at the tank outlet closes automatically on a pipe rupture.
- First-stage regulator steps 7 bar down to ~1 bar for the buried main.
- 85% auto fill-stop, gauges and multivalve; earthing, bonding and lightning protection.
- Fire response — 2 × 9 kg extinguishers, fire sand, signage and a locked fence.

Pipeline & apartments
Buried mains carry gas to each building, where a staged regulator drops pressure to a safe ~34 mbar before it reaches any appliance.
- Buried MDPE PE100 SDR11 main laid 600–900 mm deep on sand bedding.
- Warning tape ~300 mm above the pipe, with tracer wire to locate it later.
- PE→steel transition fittings where the main rises at the building wall.
- Second-stage regulator drops 1.0 bar → ~34 mbar, protected by paired OPSO / UPSO shut-offs.
- Steel riser in a ventilated shaft with a lockable isolation valve per floor.
- Smart meter and isolation valve at each apartment entry; gas & CO detectors on a 24 V solenoid.

Stepped down, stage by stage
Gas leaves the tank at high pressure and is reduced through certified regulators to a safe appliance pressure — with over- and under-pressure shut-offs guarding the low-pressure network.
