The City of Albuquerque appeals from a judgment awarding damages against it for the negligent maintenance of its sewer lines. The complaint alleges damages in amount of $20,000.00, and the cause was tried to a jury. The denial by the court of appellant’s motion for a directed verdict at the close of the evidence is the principal point on appeal.
The appeal challenges (a) the sufficiency of the evidence to support the verdict, (b) the giving of certain instructions, and (c) the refusal-by the court of certain requested instructions.
On December 31, 1962, sewage from the appellant’s eight inch sewage lateral or sewer feeder line backed up into the residence of appellees located at 148 Richmond Drive Southeast, flooding the basement of the premises with sewage to a depth of some 5 or 6 inches, thereby causing damages to the premises and furnishings therein. The back-up lasted for about 5 minutes and suddenly stopped. There is testimony that appellant’s crew dispatched to appellees’ residence shortly after the incident were unable to determine the cause of the back-up.
The appellant makes the .contention that since the cause of the back-up was ■unknown and; that1 it did -not have notice of the cause, the city is not liable, in damages. The appeal cannot be disposed of on *156this hypothesis. While the fact that a sewer does hack-up is not of itself proof pf negligent operation, nevertheless, a municipality is liable for negligence in the operation and maintenance of its system.
The city sewer system embraces more than 800 miles. The manholes in and adjacent to the 400 block of Richmond Drive Southeast are more than 12 feet deep, and on occasions sewage rises to within 3 feet of the ground level. Previously the city had adopted a policy of cleaning by rodding its sewer lines each three months, particularly where root trouble prevailed. In the 300, 400 and 500 blocks of Richmond Drive Southeast there is evidence of “quite a few trees and quite a few roots.” But the city failed to pursue this policy consistently in this area. Our review of the evidence discloses the following. The appellees had this same trouble twice previously, once in 1959 and again in 1960, of which the city had knowledge. The 400 block was completely rodded in May, 1960; one-half was rodded in June, 1960; one-half was rodded in September, 1960; one-half was rodded in November, 1960; entire block rodded in March, 1961; one-half was rodded in May, 1961; one-half was rodded in October, 1962. Those instances 'where the block was only partially rodded, the record does not disclose which half. Thus, the last' time the entire 400 block was rodded was March 7, 1961, some 22 months prior to the incident in question.
In addition to the 800 mile system, appellant also operates and maintains 150 miles of storm sewer, amounting blockwise to some 9500 blocks. There is evidence that over the previous five-year period, the appellant had some 100 coinplaints, averaging one complaint for each 192 blocks. The evidence discloses further that 7 per cent of all complaints related to 5 blocks, the 100 block to the 500 block inclusive, Richmond Drive Southeast.
We think the evidence afforded ample basis for a reasonable inference to be drawn therefrom that the cause of the back-up was appellant’s negligence in failing to exercise reasonable care to keep its sewer line free of obstructions. Compare Murphy v. City of Carlsbad, 66 N.M. 376, 348 P.2d 492; Barker v. City of Santa Fe, 47 N.M. 85, 136 P.2d 480; New Mexico Products Co. v. New Mexico Power Co., 42 N.M. 311, 77 P.2d 634; Pardini v. City of Reno, 50 Nev. 392, 263 P. 768; City and County of Denver v. Mason, 88 Colo. 294, 295 P. 788; 4 Dillon on Municipal Corporation, 5th Ed. p. 3061; McQuillan on Municipal Corporation, 3rd Ed. Vol. 18, § 53.125. See also City of Holdenville v. Moore, Okl., 293 P.2d 363, 59 A.L.R.2d 276.
Having concluded that the evidence was sufficient to support the verdict, it follows that the denial of the motion for a directed verdict was proper.
*157The point is made that the court erred in giving instructions 17 and 18. We find no difficulty in disposing of this point. The objection to the instructions, in part, reads-:
“ * * * not being a true statement of law in that it presents to the jury the view that a trespass may be committed by a negligent act as opposed to an intentional act and for the further reason that it presents to the jury for their consideration the third cause of action heretofore dismissed upon motion of the city and order of the court.”
On appeal the point is made that the instructions are not supported by the facts. Clearly, the point raises questions entirely different from those interposed by the objection. We have consistently held that in order to preserve error it is necessary to tender a correct instruction or to point out the specific vice in the instruction given by objection thereto. Hendricks v. Hendricks, 55 N.M. 51, 226 P.2d 464; Zamora v. Smalley, 68 N.M. 45, 358 P.2d 362. See also State v. Compton, 57 N.M. 227, 257 P.2d 915; Horrocks v. Rounds, 70 N.M. 73, 370 P.2d 799; Baca v. Baca, 71 N.M. 468, 379 P.2d 765.
Obviously, the objection was'not enough to alert the mind of the trial court to the specific vice now claimed in the instruction. A party will not be permitted to change his theory of the case on appeal. Hendricks v. Hendricks, supra.
A further point is made that the court erred in refusing to'give its tendered instruction number 2, the pertinent part of which reads:
“Prior notice, actual or constructive, is necessary as‘ a condition precedent to the city’s liability. Constructive notice may be inferred from a duty to inspect and to clean the sewer when necessary.
“You are instructed that if you find from the evidence that the obstruction arose so suddenly that the city had no opportunity to have either actual or constructive notice of such condition, then you must find that the city was not 'negligent with respect to its maintenance and operation of the sewer line.”
This point is without merit. The tendered instruction is repetitious and is covered by the court’s instruction number 21, which, in part, reads:
“The plaintiffs have alleged that the city was negligent in the maintenance and operation of one of its sewer lines. Prior notice, actual or constructive, is necessary as a condition precedent to the city’s liability for negligence. Constructive notice may be inferred from a duty to inspect and to clean the sewer when necessary.
“If you find from the evidence that the city had no actual or constructive *158notice that the sewer might back-up in time to avoid the damage to the plaintiffs’ house then you must determine whether or not the prior sewer backups testified to by the witnesses were sufficient to put the city on notice of the possibility of another back-up and you .must also determine, if the city was put on notice, whether the city exercised reasonable care in the maintenance and operation of the sewer line.”
Finally, appellant contends that the court erred in refusing to give the following instruction tendered by it. The instruction reads:
“No. 11 — You are hereby instructed that if you find that the defendant is liable, you may return a verdict for those damages only arising from the injuries suffered by the property, as shown by the evidence, and under no circumstances are you to consider as damages any sickness, or physical or mental' discomfort suffered by the plaintiff herein.”
The refusal was not error. The court properly instructed the jury as follows:
“Ño. 16 — you are instructed that if you ■ find the issues in this lawsuit in favor of the plaintiffs, then you will award them damages 'in such amount as will reasonably compensate them for itbe-Jnjnrie? sustained.”..- 1 ' . '. .
There is evidence that the property was worth $20,000.00 and that its value was depreciated to the extent of from 35% to 50% of its value by the flooding! The amount awarded was $4,100.00.' Appellees did not seek damages for sickness, physical or mental discomfort suffered- by them, and there is nothing in the record to indicate that damages were awarded for anything other than for actual damages to the property.
The judgment should be affirmed, and it it so ordered.
