Water Tanks & Booster Pump Sets
NLS Contractors installs water storage tanks and booster pump sets in Riyadh, Jeddah, Dammam and Khobar and across the Kingdom: GRP, concrete or steel tanks, transfer pumps, VFD booster sets in duty and standby, level controls and chlorination points. Work follows SBC 701 and the pump maker's requirements, with disinfection and pump test records at handover.
In many buildings the mains pressure is not enough to reach the upper floors, and supply can be interrupted. A storage tank and a booster pump set make the building independent of that. Water enters the tank, transfer pumps lift it to roof tanks where those are used, and the booster set pushes it at steady pressure to the fixtures.
Tanks are GRP panel tanks, reinforced concrete tanks or steel tanks, as the specification says. Whatever the material, a tank needs an inlet with a float or modulating valve, an overflow, a vent with an insect screen, a drain, an access hatch and level sensors. A two-compartment layout lets one half be cleaned without cutting supply. Materials in contact with potable water must be approved for it.
Booster sets are packaged pumps with a VFD controller and pressure sensors, arranged duty and standby so that one pump can fail without losing supply. Transfer pumps move water between tanks. The pump maker's installation requirements rule: suction conditions, anchoring, vibration isolators, flexible connectors and the electrical connection. Pump sets can be sourced through NLS Industries, and electrical panels through NLS Power.
Sizing comes from the design: daily demand from the plumbing design and the consultant's storage criteria fix tank volume and booster flow and head. The installation delivers what is specified, and the duty point is checked against the pump curve at start-up.
Before use, the tank is tested for watertightness, cleaned and disinfected, and the certificate goes into the file. The pump set is started up, flow and pressure points are recorded against the curves, and the VFD, level controls and alarm signals are tested. Chlorination points are installed and tested where the system includes dosing. Price depends on tank volume and material, pump ratings, pipe sizes and the controls scope. Lead time depends on scope and the offer states it. Send the plumbing drawings, pump schedule and curves, tank details, specification, BOQ and the site city.

Frequently Asked Questions
What size of water tank does a building need?+
It is set by the plumbing design and the consultant's storage criteria, from the daily demand. The installation delivers the specified tank and checks that the pumps match the design duty.
Why use a VFD booster set?+
A VFD varies pump speed to hold the set pressure as demand changes, instead of cycling pumps on and off. The duty and standby arrangement keeps supply running if one pump trips.
How is a new water tank disinfected?+
It is cleaned, filled and dosed with chlorine at the concentration and contact time in the specification, then flushed and tested. The certificate goes into the handover file.
Can you install pumps that the client supplies?+
Yes. Setting, piping, electrical interface and start-up of client-supplied transfer and booster pumps is a normal scope, installed to the pump maker's instructions.
