Severn Trent said properties in the SY6 area, which includes Church Stretton, All Stretton, Hamperley, Cardington, Hollyhurst and Leebotwood, were affected as of 6.01am.
A company spokesman said the repairs were completed by 2:37 p.m. after repairs took several hours longer than expected.
“You will see that we continue to work in the area to restore the place that burst. However, this should not affect your water supply,” the company told customers.
“Thank you for your cooperation while we repaired this explosion.”
