Work to repair two-metre deep hole on a residential street could begin tomorrow (Saturday, April 23).
Ringway engineers were on site early this morning to investigate the hole in Bunyan Close, Tring, which is not thought to be a sink hole.
Thames Water workers arrived at 1pm with specialist equipment for surveying pipework and underground cavities.
Herts County Councillor, Nick Hollinghurst, who was on the scene, said: “This is a serious matter and a considerable worry for local homeowners.
“Fortunately it does not appear to be one of those so-called ‘swallow holes’ which have caused so much damage elsewhere in the county.
“The HCC contractors staff were first thing this morning - but it a pity that Thames Water were not able to co-ordinate in a timely manner.
“I believe that there was a near five-hour delay until their team arrived with the necessary specialised surveying equipment.
“We must sympathise with the residents and hope that a permanent repair can be completed before too long.”
It is believed the hole was caused by a leaking water pipe.
