Ask about GRP tanks. The answer is here.

A common rule: people in the house × 150 to 250 litres a day × two or three days in reserve. A family of eight usually needs 3,000 to 6,000 litres; we help you choose when you ask for a quote.

The tank is built to be buried and stays sound when installed to the guide: a concrete slab carries the load above it and backfill on top stays within 20 cm.

The wall is opaque and the inner surface smooth, so no light gets in and algae cannot grow. We recommend cleaning through the manhole every six months.

Any tank above ground takes more sun than a buried one. The opaque wall keeps light out, but the coolest water comes from a buried tank or an above-ground tank in shade.

Algae need light. Our tank wall is opaque and the manholes have GRP lids. We recommend cleaning through the manhole every six months.

A level, even surface that carries every saddle, such as a flat concrete slab. Do not set the tank on sloping or uneven ground.

Multiply the people in the house by 150 to 250 litres a day, then by two or three days of reserve. A family of six usually needs 2,000 to 4,500 litres. Do not oversize: water that stands too long loses quality.

Your building engineer decides. Count a tonne for every 1,000 litres of water, add the tank's own weight, and choose a spot the slab can carry.

If it will not pass the stairs and roof opening, it is lifted by crane from the street. Crane placement is a paid service, priced in the quote.

SBC 702 lists glass fibre among permitted septic-tank materials. Acceptance of your design and installation comes from the municipality's inspection, which is why we build to its requirement.

The code sizes the tank by the number of building users or the waste volume, with a 2,850-litre liquid minimum. Your engineer or municipality sets it; if you do not know, tell us how many people use the building.

Under the code, when sludge reaches one-third of the liquid capacity. For a sealed holding tank, a larger capacity means longer between pump-outs.

Our size chart runs to about 100,000 litres horizontal at 3.50 m diameter, and 100,000 litres vertical. Beyond that we design the tank to the project.

Common sizes are in stock; other sizes take about a week depending on the order, and large quantities are scheduled with production, with the date stated in the quote.

Yes. Our draughtsman prepares a drawing with dimensions and nozzle positions, attached to the quote.

Yes. Any capacity can be built on one of our seven diameters by changing the length. Tell us the capacity and the longest length or widest diameter the site allows.

Custom sizes take about a week, depending on the order.

We quote box-shaped tanks to your dimensions, with a drawing and installation guide. Send the length, width and height available.

No. We build the storage vessel only. System design, installation, inspection and the completion certificate are the responsibility of the fire contractor registered on the Salamah platform.

That is for the designer and the authority to decide. We build to the specification the designer writes and do not claim conformity with any standard.

The usable volume from the fire design in litres or gallons, the number of compartments, the nozzle schedule if you have one, and the project city. If the tank also holds domestic water, give us the fire reserve volume.

No. New stations need tanks below ground in a concrete chamber with leak monitoring. We build above-ground diesel tanks for on-site storage.

We build diesel tanks for above-ground use only and do not supply buried fuel tanks.

The generator supplier sets it from hourly consumption and the running hours between refills. Give us the capacity they recommend and we build it on one of our diameters.

No tank suits every chemical. Resistance depends on the resin and on the chemical, concentration and temperature, which is why we ask first and select the resin from the supplier's data.

Ask for it in your request and we confirm in the quote which data we send with the tank.

State in your request what your project specification calls for: site bund, integral bund or none. We confirm what we will build in the quote.

Whatever your truck bed and permitted payload allow. Send the bed length and width and the payload, and we will suggest the capacity and size.

In a part-full tank, water surges forward and back when braking and rocks the truck. Baffles break up that movement; we set how many by the tank's length.

The opaque wall keeps out light and algae, and the smooth inner surface is easy to wash. Clean the tank regularly through the manhole.

The sun heats water, not the tank material. A buried tank stays cool; an exposed roof tank warms in summer like any other, so shade it or keep the main tank underground.

Algae cannot grow without light, and our tank wall is opaque with a tight cover. Contamination usually comes from an open lid or a tank left uncleaned, so keep the manhole closed and clean every six months.

No. We do not excavate, pour concrete or backfill. We build, deliver and crane-place the tank on request, and send the installation guide for your contractor.

Yes. Send the internal dimensions of the old pit and its opening; we build a tank whose diameter and length fit, installed in the prepared pit per the installation guide.

Every six months through the manhole. Before draining it, the National Water Company offers a tank-washing permit request so the draining is not recorded as a violation.

We deliver and crane-place the tank, priced in the quote. Excavation, base, backfill and plumbing are the building contractor's, using our installation guide.

It depends on Friday attendance and what the tank feeds: ablution, toilets, coolers. Use the method on this page, or send attendance and the drawing and we will suggest a capacity.

Yes. The invoice and warranty certificate are issued in the name you give: the donor, the committee or the supervising body.

Every six months through the manhole, with a check of the cover and vents in between.

Send us the specification and we will answer clearly: what we build as written and what needs a change. We do not promise conformity to a specification before reading it.

Yes. Send the internal pit dimensions and opening, and we build a tank whose diameter and length fit.

A tank drawing with dimensions and openings, the installation guide, and copies of our ISO certificates, commercial registration and VAT certificate. The warranty certificate is issued to the entity after delivery.

Yes, we build to order with one or more compartments. State the volume needed in each compartment in your request.

Yes, on a level base that supports it fully, once the building's engineer confirms the roof can carry it full: each 1,000 litres of water weighs about one tonne.

Common sizes are in stock; other sizes take about a week, depending on the order.

Send it and we will respond clause by clause: what we build as written and what needs a change. We do not promise conformity before reading it.

Yes, we deliver to every region, with transport and crane placement priced in the quote.

Common sizes are in stock; others take about a week, depending on quantity. The delivery date is set in the quote.

Yes, to every region. Send a map pin and the track condition so we send the right truck and crane; the cost is in the quote.

We agree the delivery day when you confirm the order. You or someone for you must be present, with the pit ready if you ordered crane placement.

The wall is opaque and the inner surface smooth, so no light enters and algae cannot grow. Keep the cover closed and clean every six months.

We deliver and crane-place on request, priced in the quote. Excavation, base and plumbing are your contractor's, per the installation guide.

Common sizes are in stock; other sizes take about a week, depending on the order. Put your opening date in the request.

Yes, to every region, in one quote listing each branch with its delivery cost.

GRP does not rust like steel, and the opaque wall keeps light off the water. The 25-year warranty covers manufacturing defects, subject to the installation guide: a level base above ground, the burial conditions below.

Yes. Two or more tanks instead of one very large one are easier to transport and clean. We fit the inlets and outlets on each tank to the connection layout you want.

Algae cannot grow without light, and the wall is opaque. Keep the cover closed and clean through the manhole every six months.

Yes, if the line can carry the distance. A tank per shed or per two sheds lets you clean one without stopping water to the rest.

Any capacity from 2,000 litres, on diameters from 1.20 to 3.50 m, with length set by capacity and the space available.

Yes. All our tanks carry 25 years against manufacturing defects from the invoice date, subject to the installation guide, including a level base and nothing stored on the tank.

That depends on the chemical, its concentration and temperature. We select the resin for each case from the resin supplier's resistance table and send the data sheet on request. If the table does not cover your chemical, we tell you before quoting.

Yes, single or multi-compartment. If vehicles or trucks drive over the area, say so in the request: the reinforced concrete slab above the tank is what carries the load.

No. We build the fire-water storage tank to the volume, suction, fill and overflow connections set by the licensed fire contractor, who owns the design, pumps and inspection.

No. We supply tanks only; process design, pumps, membranes and operation stay with the plant contractor.

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.

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.

Each owner qualifies suppliers per commodity under its own procedure. Tell us the owner and the commodity and we will state our position plainly before quoting.

We say so in our reply and do not send an offer that does not meet the specification.

No. We make above-ground diesel tanks for generators and plant. Buried fuel-station tanks have their own requirements and are outside our scope.

Common sizes are in stock. Send the capacity and quantity and the quote, within one working hour, confirms what is available.

No. We build, deliver and crane-place on request. Excavation, base and backfill are the contractor's; the installation guide comes with the quote.

Either, to your municipality's requirement. Include the requirement in the request if you have it.

Hourly fuel use × daily running hours × days between fills. The generator supplier gives the consumption figure; send it to us and we will propose a size.

GRP does not rust or corrode and the opaque wall keeps light out. Set an exposed tank on a level, even base and store nothing on top of it.

Yes. We size the fill connection to the tanker coupling and add a vent and overflow. Give the coupling size in the request.

Yes. Choose "Yes, data sheet and drawings" in the form and the drawing and data sheet come with the quote; other documents follow as the consultant requires.

Send the specification. We review the clauses and state in our reply which requirements we meet and which we do not. We never write compliance with a standard into a quote without a document to back it.

Yes. We build on fixed diameters, so the same size repeats across every unit, and supply can be phased to your programme.

Yes. We fill the bill of quantities and price schedule in the booklet's format with VAT, and attach the data sheet, drawings, installation guide and warranty terms.

Yes: the bid bond when the tender requires it, and the performance security after award within the stated period.

Yes, to every region by our own trucks or carriers, with the delivery date in the quote. Common sizes are in stock; other sizes take about a week, depending on the order.

We do not publish them; they are agreed with each partner by region, volume and freight once the partner form is in.

Your business type, city, expected monthly volume and company name. Once we agree terms, we ask for your commercial registration and VAT certificate so tax invoices can be issued to your company.

The factory. The certificate is issued in your end customer's name: 25 years against manufacturing defects, subject to installation per the guide, and 6 months on mechanical fittings.

Each tank is built to its own capacity, diameter and fittings, and delivery and crane costs vary by city. A quotation gives the price of your tank rather than a list price that may not apply.

Choose 'Not sure, advise me' and tell us how many people the tank serves. The usual rule is occupants × 150 to 250 litres a day × two or three days of reserve; the sizing guide explains it.

The quotation shows the price before VAT and the total after VAT.

Yes, to every region of Saudi Arabia from our Dammam factory, priced in the quotation.

It depends on the city, the number of tanks and their size, and is shown as a separate line in the quotation.

Delivery brings the tank to your site. Lowering it into the pit or onto the base is a separate crane service, priced in the quotation when requested.

No. Crane placement is a paid service shown as its own line, ordered only if you need it.

Yes. Order delivery only and arrange the crane yourself; the tank has a lifting lug for safe placement.

We do not place a tank in an unfinished pit, as that breaks the installation and warranty conditions. We confirm the pit is ready before booking delivery and placement.

Yes. Capacity is set by length, so any capacity can be built on the diameter that suits the site.

A longer tank on a smaller diameter. At 1.20 m diameter we have built 6,500 litres, which suits side passages and narrow plots.

Yes. Internal partitions are made to order and shown on the drawing attached to the quotation.

Yes. The drawing and data sheet come with the quotation for consultant review; other documents are prepared as the project requires.

We do not state compliance with any standard we hold no certificate for. Send the standard named in the specification and we will tell you plainly what we can provide.

Yes, in the entity's name with its VAT number.

No. Excavation, base, slab and backfill belong to the site owner or contractor, and we give them a written guide with every dimension.

Extra soil loads the tank shell. The reinforced slab is what carries loads above, not the tank.

The guide sets the order: part-backfill the sides, fill the tank with water, then complete the backfill. The water holds the tank in place and balances the backfill pressure around it.

5 × 200 = 1,000 L a day, so 2,000 litres covers two days and 3,000 litres three days.

At 200 L per person it covers up to 12 people for two days, or about 8 people for three days.

Yes, if they are supplied from the same tank. Add their daily use to the household figure before multiplying by the reserve days.

Tank diameter plus 10 cm blinding, 10 cm sand bed and the clearance up to the slab. The quotation gives the diameter and length so your contractor can work it out.

The guide specifies clean sand. Soil with rock can break the tank, and that breakage is not covered by the warranty.

Loads above the tank are carried by the reinforced slab, not the tank, and your engineer designs the slab for the expected load.

The sun heats water, not the material. A buried tank stays out of the sun and delivers cooler water; any roof tank warms up whatever its material.

Algae grows where light gets in and cleaning is neglected. Our tank walls are opaque with a smooth inner surface and a sealed manhole, and we recommend cleaning every six months.

We do not quote a design life without a document to support it. What we commit to in writing is the warranty: 25 years from the invoice date against manufacturing defects, subject to the installation guide.

No. It is 25 years on every tank we make, underground, roof, vertical, septic and made-to-order, subject to the installation guide.

On the commercial invoice date, so keep the invoice with the certificate.

No. We do not excavate or install; the warranty covers manufacturing defects in the tank.

We recommend every six months; the National Water Efficiency Centre advises servicing and leak-checking an underground tank at least once a year.

If you are on the National Water Company network, request the tank-washing permit first so no violation is recorded.

Clean the tank and check that the manhole cover seals and the vents are intact. If the taste persists, call a specialised cleaning and disinfection company.

Yes. SBC 702 lists fibreglass among septic tank materials, provided the tank is watertight and a single unit.

2.85 m³ of liquid capacity (2,850 litres), rising with the number of building occupants.

The code calls for at least two chambers, and your municipality decides what it accepts. We build one or two chambers to its requirement.

The standard horizontal tank is about 1.80 m in diameter and 4.00 m long. It can also be built at 2.00 m diameter and shorter, or 1.50 m diameter and longer.

Horizontal, about 1.20 m × 4.50 m, or 1.50 m × 2.90 m.

At 1.20 m diameter, 1.95 to 2.7 m for 2,000 to 3,000 litres; at 1.80 m diameter, 2.2 to 4.5 m for 5,000 to 11,000 litres.

A manufacturer. The tanks are made in the factory's own hall in Dammam Third Industrial City and sold direct, and the quotation comes from the factory sales desk.

Yes. Length is set by capacity on each of the seven diameters, so a size such as 6,500 litres at 1.20 m diameter can be made. Send the capacity and the longest length or widest diameter the site allows.

Both. A villa owner can order one water tank, and a contractor can order tanks for a whole project. For large quantities a delivery schedule in batches is proposed with the quotation.

No. The three certificates cover the factory's quality, environmental and occupational health and safety management systems, not the product.

24EQNY62, 24EENB86 and 24EONS74 are the numbers of the three certificates. Ask for the copies with the quotation and match the number and validity date.

Laura does not state compliance with any standard for which it holds no document. Send the standard named in the specification and the quotation will say what can be provided.

The factory works Saturday to Thursday, 8:00 to 18:00, so the reply comes on Saturday morning.

Yes, visitors are welcome. Contact the sales desk to agree a time; the factory is in Dammam Third Industrial City.

Yes. The tank is prepared and loaded in the factory yard, and the quotation shows the price without delivery. Agree the collection time beforehand.

They are different materials and each has its place. GRP is a glass-fibre and resin laminate that can be built to any capacity, and Laura's tanks are designed for burial. The GRP versus plastic guide compares them point by point.

No. It applies to all Laura tanks, underground, above-ground and vertical, against manufacturing defects, subject to the installation guide.

Laura does not excavate, pour concrete or backfill. It makes the tank, delivers it and places it by crane on request; the installation guide sets out the contractor's part.
