The fire that has been burning inside Power's Drive Tunnel has resulted in significant rockfall inside the tunnel which has come to light this afternoon.
This has resulted in damage to AquaGib and GibElec infrastructure. This possibility had been considered a risk and as such planning has been in place over the last two days in order to safeguard water supply as much as possible.
The AquaGib reverse osmosis plant has not been operational since Tuesday due to the loss of power. Works are in place to restore normal operations to the plant as soon as power is restored which is expected later tonight. AquaGib are working with the GFRS who are providing safe access to investigate and assess any potential damage to its pipework. The full extent of any damage will not be known until power is restored and water can be pumped through.
AquaGib is working together with Government to explore all scenarios in the event that damage to the pipework is confirmed, and all contingency routes are being followed to ensure that normal water supply to essential services and to the public is safeguarded.
In the event that the pipework is damaged, it is estimated that repairs can take up to 5 days before AquaGib can resume normal production. This means that existing reserves need to be carefully managed over the coming days. In order to ensure supply to essential services and to the public, other sectors which are the biggest consumers of water will be temporarily restricted for a period of 5 days.
The Government has issued instructions for the immediate implementation of the following temporary measures in order to conserve the existing potable water reserve and maintain water pressure:
- All fresh water supply to non-essential premises will be restricted from 23:00 tonight until 07:00 tomorrow morning.
- All street flushing with fresh water stopped
- All watering of all non-lawn plants in parks, in town, on roundabouts and in road barriers stopped
- Watering of lawns in Government parks reduced by 100% or switched to using an alternative brown water supply
- Supply stopped to the GSLA Hockey pitch and GASA indoor swimming pool
- Construction activity stopped
- Supply for the production of cement stopped
These measures are temporary and designed to ensure normal potable water supply to the public in the event that there is damage to the AquaGib pipes within Power’s Drive Tunnel. If there is no damage to pipework or repairs take less than 5 days, these restrictions will be lifted as soon as possible.
At this stage, AquaGib says it regrets to advise that customers in the Upper Town area may already be experiencing significant fresh water supply issues. This is due to the nature of Gibraltar’s fresh water system and the fact that water pressure is produced by gravity. In order to alleviate the situation for residents in that area, AquaGib are deploying potable water bowsers with immediate effect.
All other avenues for the topping-up of existing reserves are being explored and actively followed through. This includes plans to import water via road and sea, and to engage temporary, portable desalination equipment to produce water in Gibraltar. The AquaGib plant at North Mole is still fully operational and is producing water as normal.
AquaGib says it hopes to resume normal services as soon as possible in the coming days and asks the general public to cooperate in by reducing water consumption as far as possible.
Update from Aquagib:
Bowsers are being deployed, the first four are located at Calpe Road, Moorish Castle Estate, Alameda Estate and Naval Hospital Road by Penny House.
A further one will be confirmed in due course.
