Dear Sir/ Madame,

I am writing this letter to thank you for all the efforts you took to repair the school water pump you had previously drilled for us. Your engineers put it back into service and into working condition immediately!

We truely appreciate your swift response to our distress call. I was getting worried as to where the pupils were getting clean water to drink, as we have been experiencing a long dry spell and our tanks were empty.

The pump was clogged with pieces of plastic, pens and debris that the students had put into the pump head and I assure you that your effort will not be wasted as I will ensure that doesn't happen again.

Once again thank you for all that you have done for our institute.

Yours sincerely

Mr Young,

Head master
