Short term impact to students & faculty
The water leak was fixed without having to install new domestic water lines
Leak was at the end of a branch line that fed an outside hose bib
NO restrooms, water fountains, kitchen or hot water heaters affected
One classroom used after school has been moved.
Mr. John Powell with PEC Structural Engineering came by BHS on Saturday to assist in inspecting foundations / walls
No sign of structural failures were detected
Recommended backfilling with dense grade and compacting
Concrete poured to match existing thickness

Potential for additional leaks is HIGH
Fixing the leaks will add additional pressure to the domestic water lines
All domestic water lines are under the slab
Below grade lines supply domestic water to student restroom, staff restrooms, water heaters, drinking fountains, custodial closets & kitchen
Alternative would be to re-pipe the school with new over-head domestic water lines
Estimated cost; 1.2mil – 1.6mil
