One tank for each liquid on site
A typical plant stores several liquids: raw water feeding the line, process water, wastewater waiting for collection or treatment, chemicals, generator fuel and a fire-water reserve.
We build all of these in GRP, which does not rust or corrode, at the capacity and diameter that fit your plot, above ground or buried.
- Raw and process water: horizontal tanks on moulded GRP saddles, or vertical tanks, with nozzles to suit the line
- Industrial wastewater and sewage: buried or above-ground holding tanks, single or multi-compartment to the design
- Chemicals: resin selected for the chemical, concentration and temperature from the resin supplier's resistance table
- Diesel: above-ground tanks for generators and plant; containment is set by the site engineer
- Fire-water: we supply the storage vessel; design, pumps and inspection stay with the licensed fire contractor

Drawings and volumes for the permit file
Every factory holds construction and operating environmental permits from the National Center for Environmental Compliance, and that file covers how wastewater is collected and materials are stored.
Our draughtsman prepares a drawing for each tank showing dimensions, capacity and nozzle positions. It comes with the quote, ready for the permit file or your consultant.
Storage warehouses must have one or more fire-water tanks with pumps feeding the fire network. We build the tank to the volume and connections in the fire contractor's design.
What we need to price accurately
We build on fixed diameters from 1.20 to 3.50 m and set the length by capacity, so the volume you need fits inside your site limits. Quotes go out within one working hour, Saturday to Thursday.

Frequently asked questions
Will GRP handle the chemicals in our plant?
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.
Can you supply buried wastewater tanks under a yard?
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.
Do you design the warehouse fire system?
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.
Can we have drawings for the environmental permit?
Yes. Our draughtsman prepares a drawing with dimensions, capacity and nozzles for each quote, usually sent the same day.
Is the invoice issued to the company?
Yes. The quote and tax invoice are issued in your company's name with VAT. Enter the company name in the form.
How long do non-standard sizes take?
Common sizes are in stock; other sizes take about a week, depending on the size of the order.
