Khazzan's standard septic tank range covers 300 to 20,000 USG in horizontal configuration, sized for typical villa, commercial, and labour camp applications. But waste water treatment plants and industrial process sites often need something the standard catalogue doesn't cover: a vertical cylindrical GRP tank built to exact project dimensions, with internal fittings positioned to match a specific treatment process. That's a custom fabrication job, not a catalogue order, and it's a regular part of what we manufacture.
Why Vertical, and Why Custom
A standard horizontal septic tank works well for straightforward wastewater storage and primary settlement. A waste water treatment plant is a different problem: water often needs to move through defined stages, sit at a controlled depth for aeration or biological treatment, and interface with equipment like aeration grids or biomedia filtration systems mounted at specific points inside the tank.
A vertical cylindrical tank gives an engineer more control over that internal geometry, and a fixed catalogue size rarely lines up with the exact diameter and height a treatment process calls for. That's why these tanks are built to a project's own specification sheet rather than picked off a size chart.
What Gets Customized on a Project Tank
A typical custom specification for a vertical GRP waste water tank includes:
- Diameter and height to project spec. For example, a 2.25m diameter by 3.0m height cylindrical tank, or a shorter 2.25m by 1.5m unit for a secondary stage, whatever the process design calls for.
- Material grade. Glass fibre reinforced with isophthalic resin is a common specification for waste water applications requiring stronger chemical resistance than a standard polyester resin lay-up.
- Internal fixing arrangements. Mounting points for an aeration grid at the base, and a biomedia retention sieve fixed to the tank wall, positioned exactly where the process design requires.
- Nozzles. Inlet, outlet, and drain nozzles fabricated to the required diameter and flange standard, for example 4-inch flanged connections.
- Structural reinforcement. Stiffeners and tie-rods sized for the tank's dimensions and the loads it needs to carry, both empty and full.
- Access. A manhole on the tank top for inspection and maintenance access, sized and positioned per the spec.
- Internal cat ladder. Fitted inside larger tanks so maintenance staff can safely access the base for inspection or cleaning.
Every one of these is a variable, not a fixed feature, which is exactly what makes this a manufactured-to-order product rather than a stock item.
Example Specification Sheets
To show what a real custom spec looks like, here are two vertical tank drawings built to the same 2.25m diameter but different heights for a multi-stage treatment system:
Wall thickness on these units is specified at 4 to 6mm, sized against the tank's dimensions and the structural load once full. Wall thickness, like every other dimension, is confirmed against your specific project requirements.
Typical Applications
- Waste water treatment plants requiring staged biological or aeration treatment
- Multi-tank systems, where a project may need several vertical tanks of different heights working together (a primary aeration tank plus a shorter secondary tank, for instance)
- Industrial and labour camp sites with non-standard footprint or height restrictions where a horizontal tank doesn't fit the available space
- Projects requiring specific nozzle sizing or fitting positions to match existing pipework or treatment equipment
Extended Warranty on Custom Tanks
Khazzan's standard catalogue septic tank range carries a 1-year manufacturer's warranty. Custom-manufactured GRP tanks, both water tanks and septic/waste water tanks, are eligible for an extended warranty of up to 3 years, reflecting the heavier-spec construction typically built into a project-specific order. The exact warranty period is confirmed as part of your project quotation.
Delivery works differently too: for standard catalogue tanks, delivery is charged separately and varies by location. For custom industrial or project orders, delivery is often quoted as part of the overall project price to the site location, confirm this directly when you submit your specification.
How to Request a Custom Quote
- Send your specification: diameter, height, nozzle sizes and positions, internal fittings required, manhole and access requirements, and any drawing you have.
- WhatsApp or call +971509583173 with the details, or email your spec sheet.
- We'll confirm feasibility, warranty terms, and delivery for your project location before you commit.
A clear written specification, similar to a typical project RFQ, is the fastest way to get an accurate quote rather than a rough estimate.
Frequently Asked Questions
Q: Can Khazzan manufacture a vertical septic or waste water tank to my own dimensions? A: Yes. Beyond the standard horizontal septic tank range, we manufacture custom vertical GRP tanks to project-specific diameter, height, and internal fitting requirements for waste water treatment and industrial applications.
Q: What material is used for custom waste water treatment tanks? A: Glass fibre reinforced plastic (GRP), often specified with isophthalic resin for stronger chemical resistance in waste water applications. Exact material specification is confirmed against your project requirements.
Q: Can internal fittings like aeration grids and biomedia sieves be built in? A: Yes. Fixing arrangements for aeration grids, biomedia retention sieves, and similar internal fittings can be built into the tank to match your process design.
Q: What's the warranty on a custom-manufactured tank? A: Custom GRP tanks, both water tanks and septic/waste water tanks, are eligible for an extended warranty of up to 3 years, longer than the standard 1-year warranty on catalogue septic tanks. The exact term is confirmed as part of your project quotation.
Q: How long does a custom vertical tank take to manufacture? A: Lead time depends on the size, complexity, and current order volume. Contact us with your specification for a project timeline.
Q: Do you deliver custom tanks outside Dubai? A: Yes, across all 7 UAE emirates. For custom project orders, delivery is typically quoted as part of the overall project price, confirm this when you submit your specification.
Q: Does the extended warranty also apply to custom GRP water tanks, not just septic tanks? A: Yes. The extended warranty of up to 3 years applies to customized GRP fiberglass tanks across both water tanks and septic/waste water tanks, not just one product line.
