Sprinkler, Hydrant & Fire Pump Installation
NLS Contractors installs sprinkler, hydrant and fire pump systems in Riyadh, Jeddah, Dammam and Khobar and across the Kingdom: sprinkler grids, risers and standpipes, hydrants, hose cabinets and pump sets with fire water tank connections. Work follows NFPA 13, 14, 20 and 24 and SBC 801, with Civil Defense acceptance support and test certificates at handover.
A fire protection package is built to be inspected. Civil Defense reviews the design, watches the tests and accepts or rejects the system, so the work is organised around the documents they ask for. The scope covers the sprinkler grid and its risers, standpipes and hose cabinets, external hydrants, the fire pump set and the connections to the fire water tank.
NFPA 13 governs sprinklers, NFPA 14 standpipe and hose systems, NFPA 20 fire pumps and NFPA 24 the underground fire mains that feed a site. SBC 801 is the Saudi fire protection code that ties them to the building. The hydraulic calculation, shop drawings and device approvals are submitted before pipe goes up, and what is installed has to match what was approved.
A fire pump set usually has a duty pump, a standby pump and a jockey pump that holds line pressure. Controllers, the test header, suction and discharge piping and the tank connection complete it. The performance test under NFPA 20 runs the pump at shutoff, at rated flow and at 150 percent of rated flow, and records pressure and current at each point. A pump that misses its curve holds up the building's acceptance, so the test is planned early with water and power ready.
Hydrostatic acceptance testing under NFPA 13 holds the sprinkler pipework at test pressure for the duration the standard sets, with no leakage. Underground mains are flushed before connection, then tested. Flow switches and tamper switches are wired to the fire alarm panel, so the sprinkler and alarm contractors need to agree who connects what.
Fire pumps, controllers and panels can be client-supplied or sourced through NLS Power, then installed and tested in the same offer. Price depends on protected area, hazard class, pipe sizes, pump rating and site conditions. Lead time depends on scope and the offer states it. Send the fire drawings, hydraulic calculations, equipment schedule, specification, BOQ and the site city. Design approval by Civil Defense is led by the owner's consultant, and the test records support the inspection.

Frequently Asked Questions
Who obtains Civil Defense approval for a sprinkler system?+
Design approval normally runs through the owner's consultant. The contractor submits shop drawings, hydraulic calculations and material approvals, and supports the inspection and the acceptance test with records.
What does the fire pump flow test involve?+
Running the pump at shutoff, at rated flow and at 150 percent of rated flow, recording pressure and current at each point, and comparing the results with the pump curve. Water and power must be ready on the day.
Can you install fire pumps that the client supplies?+
Yes. Setting the pump set, piping, test header, controller connection and testing is a normal scope. Panels and pumps are also available through NLS Power.
How does the sprinkler system connect to the fire alarm?+
Flow switches and valve tamper switches are wired to the fire alarm panel. The sprinkler and alarm packages agree who supplies, mounts and connects each device.
