GRP water tanks for schools and universities: reserve that keeps running during cleaning
We build water tanks for schools, colleges and universities to the capacity on the consultant's drawings, and split it across two or more tanks so supply continues through cleaning and maintenance.
- 25-year warranty
- Multiple tanks for campuses
- Drawing with the quote
- ISO 9001, 14001 and 45001
We reply within one working hour, Saturday to Thursday.
The consultant sets the capacity; we build it
Tank capacity for an educational building comes from the consultant, based on students, staff and facilities. We build to the capacity on the drawing, on a diameter from 1.20 to 3.50 m to suit the location.
Without a drawing, the usual estimate is daily consumption from the water bill or meter × the reserve days required. A school on tanker supply needs more reserve than one on the network.

Two tanks instead of one: maintenance without outage
A school cannot shut off water for a day to clean a tank. We suggest splitting the capacity across two or more tanks, or one two-compartment tank, so one is drained and cleaned while the other feeds the building.
On larger campuses each building can have its own tank, so one tank under maintenance never stops the campus. Drinking water can be stored apart from service and toilet water where the consultant asks for it.
Cleaning, heat and access
- Opaque wall that keeps light out so algae cannot grow, and a smooth inner surface that is easy to clean.
- 50 cm manhole on underground tanks, wide enough for a cleaner to enter.
- A buried tank under a concrete slab stays out of the sun and out of students' reach, opened only through the manhole.
- Clean every six months; school holidays are a natural slot.
How tanks are bought: the project contractor or a government tender
On new projects the building contractor buys tanks to the consultant's specification; we send the quote with a tank drawing and installation guide.
Public schools and universities buying directly for maintenance or replacement usually go through a tender, direct purchase or framework agreement. We quote in VAT format with the technical documents; see the government tenders page for detail.
Frequently asked questions
Can you build to the specification in the tender booklet?
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.
Can a new tank go into an old concrete tank's pit?
Yes. Send the internal pit dimensions and opening, and we build a tank whose diameter and length fit.
What documents come with the quote?
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.
How long does manufacture take?
Common sizes are in stock; other sizes take about a week, depending on the order. The delivery date is confirmed in the quote.
Do you deliver and place the tanks?
Yes, to every region. Crane placement is a paid service priced in the quote; excavation, base and backfill are the project contractor's.
