Raw water, treated water and dosing tanks for treatment and desalination plant contractors
You design the process; we build the vessels in it, to the capacity, diameter and nozzle schedule on your drawings, in our Dammam factory.
- Built to your nozzle schedule
- Drawings for the consultant
- 25-year warranty
- Delivery to every region
We reply within one working hour, Saturday to Thursday.
We make the tanks; the process is yours
Laura does not design or supply treatment plants. We build the vessels the plant contractor places in the flow sheet, upstream, downstream and alongside the process.
GRP does not rust or corrode, and the opaque wall keeps light out, so algae do not grow in stored water.
- Raw water and well water storage ahead of treatment
- Treated water and desalination product water storage
- Backwash and cleaning water tanks
- Equalisation, collection and sludge holding tanks for wastewater plants, single or multi-compartment
- Dosing chemical tanks, with the resin chosen for the chemical
Dosing chemicals: resin chosen per chemical
No GRP tank suits every chemical. Give us the chemical name, concentration and temperature; we select the resin from the supplier's resistance table and send the data sheet on request.
Secondary containment around chemical tanks is a project specification set by the consultant. The chemical-handling licence sits with the operator that stores and uses the chemical, under the Chemical Materials Management Law and its 2025 executive regulation.
What comes with the quote
We build on fixed diameters from 1.20 to 3.50 m and set the length by capacity, horizontal on GRP saddles or vertical, so the volume fits the space on site.
- A drawing for each tank with dimensions, capacity and nozzle positions, for consultant review before fabrication
- Resin supplier data sheet on request
- Water-fill test: if the specification calls for one, state it in the request and we confirm in the quote what we provide
- Installation guide and warranty terms
- VAT-format quotation in your company's name
Delivery to the plant site
We deliver to every region by our own trucks or carriers; large tanks travel on low-bed trailers. Crane placement is a paid service priced in the quote; foundations, excavation and backfill are by the contractor.
Common sizes are in stock; other sizes take about a week, depending on the order. The 25-year warranty runs from the invoice date against manufacturing defects, provided the installation guide is followed.
Frequently asked questions
Do you build the whole treatment plant?
No. We supply tanks only; process design, pumps, membranes and operation stay with the plant contractor.
Will algae grow in treated-water tanks?
The wall is opaque and the manhole sealed, so no light gets in and algae do not grow. We recommend a regular cleaning schedule through the manhole.
How do you choose the resin for a dosing tank?
From the chemical name, concentration and temperature, using the resin supplier's resistance table. Send these with the request; if the table does not cover the chemical, we tell you before quoting.
Will you follow the nozzle schedule on our drawing?
Yes. Inlets, outlets, vents, overflow and manholes are made at the sizes and positions on your drawing, and our draughtsman shows them on the tank drawing for your review.
Can you make a two-compartment tank?
Yes, single or multi-compartment to the design, as used for equalisation and settling.
What is the warranty?
25 years from the invoice date against manufacturing defects, subject to installation per the guide, and 6 months on mechanical fittings.
