“(a) Movement of water leading to uncontrolled restoration of supply; (b) The specific risk associated with the uncontrolled restoration of supply is fire/explosion following ignition of gas which had entered the property because the consumer's Emergency Control Valve (ECV) or appliance had not been turned off immediately after the time when the gas supply had been lost; (c) Low gas pressure leading to flame failure and unburnt gas entering the property in the absence of appliance flame supervision devices leading to the risk of fire and explosion; (d) Combustion at low pressure leading to the production of Carbon Monoxide (CO) which is toxic and hence is a health hazard; (e) Water that was not extracted from the originally affected area of the Incident may migrate to other parts of the network and cause future problems.”
“Summary. By way of summary, the following facts are agreed: (1) SGN's obligation to make FSG payments to customers under theGas (Standards of Performance) Regulations 2005 (as amended) arose after the expiry of a period of 24 hours from the time when the gas supply to such properties was initially interrupted (i.e. they did not have any gas supply, or the gas supply was insufficient and/or fluctuating) where such supply has not been resumed, not from the time when the 'Emergency Control Valves (ECVs)' are turned off; (2) In the vast majority of cases, gas supply was initially interrupted by the ingress of water rather than by the isolation of the ECVs (which occurred later); (3) More generally, by reference to paragraph 80 of the gas experts' joint statement, it is agreed that there is a time lag between events (d) to (g) and (h) and (i) (i.e. the gas supply is initially interrupted under (d) before the ECVs are turned off under (h)); and such time lag will vary from incident to incident and property to property. The time lag will depend on considerations such as mobilisation of personnel, assignment of those personnel to specific roads, and access to properties: (James B/2/10, paras.18-21).”
“16. The escape of water from the Defendant's water main and/or the damage to the Claimant's gas main was caused by the Defendant's negligence. PARTICULARS OF NEGLIGENCE (a) The Defendant carried out a repair to the water main which was insufficient to contain the water within the main; (b) The Defendant failed to inspect its main adequately or at all, either before or after its repair to the water main; (c) The Defendant failed to replace the relevant length of its damaged water main on or about 23 December; (d) The Defendant failed to put a system in place to respond swiftly to complaints of a burst main; either generally or once the burst had occurred on 23 December; (e) The Defendant failed to switch off its water supply and/or take any other steps to prevent escape of water, promptly once initial reports of water ingress into the gas system had been received by it; (f) The Defendant otherwise failed to take reasonable care for the equipment of other apparatus in the street which might be affected by discharges from its water main; (g) The Defendant failed to respond swiftly and/or adequately to the complaints of loss of gas set out above, until about 4.00am on 30 December 20l2. 17. The Claimant will also rely on the principle of res ipsa loquitur. (i) Water pipes do not burst and/or run free for sufficiently long enough to cause damage to a nearby gas pipe, without there being negligence on the part of the Defendant. (ii) Repairs do not fail within 5 or 6 days of being effected without there being negligence on the part of the Defendant in the course of the repair.”
"The claim in negligence: 7A. The Defendant pleads as follows to the allegations of negligence at paragraphs 16 and 17 of the Particulars of Claim. (a) It is denied that the Defendant owed the Claimant any relevant duty of care at common law in relation to the matters complained of without prejudice to or derogation from the generality of the foregoing denial: (i) The Defendant repeats paragraph 15(c) below; (ii) In view of the fact that, as set out at paragraph15(c) below, the strict liability compensation scheme of the NRSWA 1991 provides a complete code and excludes the operation of common law negligence, the Defendant owed the Claimant no duty of reasonable care at common law and accordingly has no liability in negligence in respect of the sums claimed at paragraphs 22 and 23 of the Particulars of Claim; (b) Without prejudice to the foregoing, subject to the Claimant establishing that a relevant duty of care was owed by the Defendant: (i) the Defendant admits breach of such a common law duty, and admits that such breach caused damage to the Claimant's Apparatus; (ii) liability for the losses claimed are not thereby admitted: The Defendant further addresses this issue under the "
“There is no suggestion that SGN ever sat on its hands and did nothing, was not making good or was not taking the steps necessary in order to make good. The fact, as is admitted that there is a time gap between the event of somebody's gas going off and that person's ECV being turned off and the works to remove water commencing is, in a sense, neither here nor there. We say this is bespoken by the facts, if SGN from the moment that reports come in of loss of gas is taking the various steps that have to be taken to remove the water and turn the gas back on, and those steps obviously include - they are all in the agreed facts - turning off the ECVs and then removing the water, all that, we say is making good. We say the FSG payments run with the fact that during the period SGN are making good.”
“(1) An undertaker shall compensate - (a) the street authority or any other relevant authority in respect of any damage or loss suffered by the authority in their capacity as such, and (b) any other person having apparatus in the street in respect of any expenses reasonably incurred in making good damage to that apparatus, as a result of the execution by the undertaker of street works or any event of a kind mentioned in subsection (2). (2) The events referred to in subsection(1) are any explosion, ignition, discharge or other event occurring to gas, electricity, water or any other thing required for the purposes of a supply or service afforded by an undertaker which - (a) at the time of or immediately before the event in question was in apparatus of the undertaker in the street, or (b) had been in such apparatus before that event and had escaped there from in circumstances which contributed to its occurrence.”
“33. If the two remedies cover precisely the same ground and are inconsistent with each other, then the common law remedy will almost certainly have been excluded by necessary implication. To do otherwise would circumvent the intention of Parliament. A good example of this is Marcic, where a sewerage undertaker was subject to an elaborate scheme of statutory regulation which included an independent regulator with powers of enforcement whose decisions were subject to judicial review. The statutory scheme provided a procedure for making complaints to the regulator. The House of Lords held that a cause of action in nuisance would be inconsistent with the statutory scheme. It would run counter to the intention of Parliament. 34. The question is not whether there are any differences between the common law remedy and the statutory scheme. There may well be differences. The question is whether the differences are so substantial that they demonstrate that Parliament could not have intended the common law remedy to survive the introduction of the statutory scheme. The court should not be too ready to find that a common law remedy has been displaced by a statutory one, not least because it is always open to Parliament to make the position clear by stating explicitly whether the statute is intended to be exhaustive. The mere fact that there are some differences between the common law and the statutory positions is unlikely to be sufficient unless they are substantial. The fact that the House of Lords was divided in Total Network SL[2008] AC 1174 shows how difficult it may sometimes be to decide on which side of the line a case falls. The question is whether, looked at as a whole, a common law remedy would be incompatible with the statutory scheme and therefore could not have been intended by coexist with it.”
