School and church leak detection
Acres of irrigated ground, several buildings on one or two meters, and a calendar that gives you one real window a year for anything that opens the ground.
The biggest pipe on site
On a campus, the grounds are the plumbing that matters
Fields, play areas, the frontage, courtyards, parking islands, the memorial garden. Add the irrigation up on a campus and it is nearly always more buried pipe than every building on the site put together: mainlines the length of a city block, dozens of valve boxes, laterals under turf and rock, and a much-rezoned controller.
It also runs before dawn, so a break performs to an empty campus. What a facilities director sees is subtler: a station that will not build pressure, a swale wet into June, turf green in a pattern that does not match the head layout, or a meter that never stops.
Constant loss or scheduled loss
Establish this first, because it halves the search. A leak on a pressurised mainline runs every hour of every day, since the mainline is live whether the controller is calling or not, while a leak downstream of a valve runs only during that station's cycle. Testing the mainline with the controller shut tells them apart.
Campuses follow rooftops
Where the Valley grew fastest, the campuses are of the same generation as the neighbourhoods around them. Census figures put about 59 percent of Gilbert's housing units and about 46 percent of Peoria's as built since 2000, and campuses of that vintage are at the age where irrigation fails at fittings and glued joints rather than along the pipe — the leak that surfaces a long way from where it starts.

Method
Half a dozen buildings and one or two meters
A campus is triaged, not searched, and the order below eliminates most of the site before anybody walks a classroom wing.
Read every meter with the campus idle
Controller off, buildings quiet: a meter still turning under those conditions is the number the rest of the job is measured against.
Separate irrigation from domestic at the existing shut-off
This one valve usually splits the loss in half and tells you which side of the campus to spend the day on, with nothing indoors affected.
Test the irrigation main in sections
Isolate and hold each length between valve boxes; sections that hold are eliminated in writing, which matters when somebody asks why the trench went where it did.
Then go building by building
Gym, cafeteria, restroom cores, classroom wings, portables, the hall — each has its own isolation point.
Acoustic and line tracing on the section that fails
Tracing the line's actual path, which on a campus that has had buildings added is frequently not the path on the drawing.
Mark and photograph before turf or slab is opened
With a fixed reference in frame — a goal post, a door number — so it can be found again weeks later during a break.
On site
Access is the district's call, not ours
Campus access rules belong to the district, the diocese or the parish office. We check in where the facilities office tells us to, stay in the area we were let into, and leave nothing open.
Fencing a test area on a field matters more than on a parking lot, and a hole left between visits is covered and barricaded.
The calendar
One real window a year, and how to be ready for it
A campus has one comfortable period for anything that opens the ground: the long break. It is also the hottest weather of the year, and nobody is on site to notice a break.
Put the finding before the break and the digging inside it
A walk of the grounds and meter readings late in the school year turn the break into planned work rather than a scramble. With the locate already documented, the trench and the turf repair are scheduled and the field is back in time. Start in July and the window gets spent looking.
An empty campus is the best diagnostic there is
Read every meter on the day the campus closes and again the day before it reopens. Nothing legitimate happens in between, so two readings across an empty month are the clearest evidence you will get.
Churches, on a different schedule
A parish campus is busy in bursts and quiet in long stretches, and those stretches are the test window.
Reporting upward
What a facilities director has to justify
On a campus the person who finds the problem is almost never the person who approves the work. A locate here is read by a business manager, a district office or a finance committee — people who were not on the field.
So it says which meters were read, what was isolated, which sections held, where the failure is with a fixed reference in the photographs, and what failed in one plain sentence.
The work behind a campus locate
Straight answers
What facilities directors and business managers ask
Can you locate it during the school year and dig over the break?
That is the sequence we recommend. The detection work happens with the campus occupied and the ground untouched, so the trench and the turf restoration go into the break as scheduled work.
Our irrigation runs at four in the morning. Do you need to be on site then?
No. We would rather take control of the controller in daylight and test the mainline with everything shut, which also separates a constant loss from a scheduled one.
We have one meter for the entire campus. Is that a problem?
It is normal and workable. One meter means the site is divided with the valves already in the ground, starting with the split between irrigation and domestic.
Do you work on the kitchen and restroom lines, or only the grounds?
Both, on the water side: supply lines under slabs, buried site lines, the service line and the irrigation. Drains, sewer, gas and water heaters are not our scope.
Send us the meter readings and a photo of the wet ground
A photo of the green patch or the valve box, plus your calendar, is enough for us to plan the finding now and the digging for the break.
