School leak detection in the North East

The North East has the fewest open schools of any English region, and much of its estate sits on former coalfield ground where settlement pulls buried joints apart.

Schools in rural areas

A rural school is more likely to sit at the end of a long private supply run, and a minority are on private water supplies rather than a mains connection.

Water wholesalers serving the region
Northumbrian Water, Hartlepool Water

Leakage allowance schemes are set by the wholesaler, but a school's account is with its retailer. Ask your retailer which wholesaler scheme applies, what evidence it needs, and what the repair deadline is, before you commission the repair.

Ground and water conditions
Former Durham and Northumberland coalfield ground, where historic mine workings and made ground produce differential settlement that pulls buried joints apart.

School building programmes in the region
Post-war expansion under the north eastern local authorities, with substantial CLASP system building after the consortium spread out of Nottinghamshire.

Largest school site by capacity
Cramlington Learning Village, 2,218 places

In Northumberland. A site of this size has a distribution network rather than a single supply run, which changes how a leak is isolated.

What this means for a survey in the North East

The ground and water conditions above are the practical part. Hard water scales fittings and shortens the life of valves and mixers. Soft water is easier on scaling but less forgiving of some older metallic pipework. Shrinkable clay moves through a dry summer and pulls buried joints apart, and former coalfield ground settles differentially for decades after the workings closed.

None of that changes the sequence: measure at the meter, isolate to a branch, locate from the surface. It changes what we expect to find and where we look first.

Case studies from schools in the North East

None published yet. Rather than write a plausible-sounding example, this page says so. When ADI supplies a school in this region that is happy to be named, or happy to be described anonymously, it will appear here with the measured loss and what the repair involved.
