Our scheduled maintenance programmes reduce outages, extend equipment life and protect water quality, helping you avoid costly repairs and downtime.

End of Well Progamme
Taking bookings Now
When a bore stops operating, we need to close it to make it safe.
If a well is inefficient or not working properly, there is a possibility that there is a break in the casing, it needs a service or has reached the end of its life and requires closing up.
If you want to investigate restoring your bore, we can investigate whether a bore liner would work for your situation. However, if not, we follow a process to safely close up the bore.
What’s Included in our End Of Bore Procedure:
- Sound out bore to hole depth
- Back-fill if required
- Grout to surface level
- Clear, detailed and council-ready End of Well Report
