delivered the opinion of the court:
The rate for each 100 cu. ft. of water obtained from plaintiffs by defendant and used by it for and in connection with its two veterans’ hospitals, as set forth in the findings, was the within-city ordinance rate as provided in certain written contracts made pursuant to and in accordance with certain prior arrangements and agreements, but plaintiffs contend that under the provisions of the City Charter and existing ordinances the higher outside-city rate was applicable, be*86cause the within-city rate so agreed upon was not expressly approved by the City Council.
During the period from October 1925 to November 1, 1931, during which an original and several renewal contracts relating to the San Fernando Hospital were made, the within-city water rate of 5 cents per 100 cu. ft., provided in such contracts, was billed by plaintiffs without any question or objection with reference thereto, and was paid by defendant. During the period November 1,1931 to September 6, 1933, the effective date of a contract termination notice given by plaintiffs, water was furnished to this hospital under the same contracts and under the same circumstances, and was billed at the higher without-city rate of 20 cents per 100 cu. ft., but defendant paid therefor at the lower within-city contract rate under renewals by defendant of the contract of November 27, 1928, under a renewal option given it therein. Each of the contracts and renewals made on and after May 27, 1926 contained a provision that either party might terminate it on ninety days’ notice. Plaintiffs did not exercise this right until about June 8,1933.
From December 1920 to March 7,1929, plaintiffs furnished defendant water at the within-city rate for the Sawtelle Hospital under an agreement with defendant but without a written contract, and thereafter .water was so furnished without question until November 1, 1931, under an original and annual renewal contracts, the last one of which extended to June 30, 1932. The controversy as to the water rate for this hospital continued from November 1, 1931 to January 1, 1932, when other arrangements, not here involved, were made by the parties.
The Sawtelle Hospital land and buildings, although not legally within the city limits, because it was a Government reservation, were wholly within the area encompassed by the outer boundaries of the corporate limits of the city.
The basis of the claim for $11,174.63 made by plaintiffs, representing the difference between the ordinance rate for water used outside the city limits and the rate for water used within the city limits, is the alleged erroneous and illegal application of rates for water which was supplied under contracts to the two institutions for uses which it is alleged were *87in both instances, outside the city, in which contracts the within-city rate was provided.
Plaintiffs contend that in the light of the fact that rates had been established by ordinance, as prescribed by the City Charter, for both within-city and outside-city uses, the executed contracts insofar as they provided for within-city rates for without-city uses were unlawful, discriminatory, ultra vires, and not binding on plaintiffs. They state their position herein to be that the Government purchased water under contracts for uses outside the city; that the Charter of the City of Los Angeles placed the duty and the power upon the Department of Water and Power to fix rates for such use; that rates were so fixed but, by mistake, the rates applicable to uses within the city were applied; that after plaintiffs discovered the mistake the water delivered to the two Federal institutions was billed for at the proper outside-city rate, and that it would have been illegal and improper for plaintiffs to have done otherwise, notwithstanding the existing contracts at a different rate.
The San Fernando Hospital buildings and a portion of the land of the site thereof were outside the city limits, but a portion of the land (13% acres out of 616.02 acres) and a pumping plant and a certain portion of the pipe lines constructed or paid for by defendant from the hospital buildings to plaintiffs’ reservoir were within the city limits.
We are of opinion on the facts and circumstances of the case that plaintiffs are not entitled to recover.
The Charter of the City of Los Angeles (finding 13) with respect to the Department of Water and Power provided as to water, so far as here material, that this Department “shall have the power and duty: (1) To construct, operate, maintain, extend, manage and control works and property for the purpose of supplying the city and its inhabitants with water, * * *. (2) To regulate and control the use, sale and distribution of water owned or controlled by the ■city; the collection of water rates, and the granting of permits for connections with said water works; * * * and, •subject to the approval of .the Council by ordinance, to fix the rates to be charged for water for use within or without •the city * * *. Such rates shall be fixed at least every *88two years; provided that, except as hereinafter otherwise prescribed, such rates shall be of uniform operation, as near as may be, and shall be fair and reasonable, taking into consideration, among other things, the nature of the use, the quantity supplied, and the value of the service; provided further, that the rates inside the City may be less, but not greater, than the rates outside the City for the same or similar uses.”
The pertinent portions of the ordinances of the City Council (finding 14) approving within-city water rates fixed by resolutions of the Department of Water and Power provided that for “water supplied * * * to consumers inside the limits of the City of Los Angeles the rates to be charged and collected * * * are as follows: * * The ordinances approving without-city rates so fixed provided that “When water is supplied * * * to consumers outside the limits of the City * * * the rates to be charged and collected * * * are fixed as follows: * *
In the petition plaintiffs alleged as one of the grounds for recovery that the water contracts at the within-city rate of five cents per 100 cubic feet of water were entered into as a result of a mutual mistake of fact and should, therefore, be reformed. But there clearly was no mutual mistake of fact (findings 16 and 27), and plaintiffs have apparently abandoned this ground since no mention of it is made in their briefs.
As to the other ground on which recovery of the higher outside-city water rate is sought, namely, the erroneous and illegal application in the contracts between the parties of the within-city rate for water furnished defendant for consumption outside the city limits at the San Fernando Hospital, we agree with the defendant that this asserted illegality disappears when the City Charter, the ordinances, and the special and peculiar circumstances of the instant case are analyzed.
After a thorough investigation by defendant, acting through officials of the Veterans’ Bureau, in 1923, 1924, and 1925, as to the advisability of purchasing a site and erecting thereon á hospital near Los Angeles for disabled veterans, and after many conferences by these officials and official rep*89resentatives of plaintiffs, the plaintiffs and the Veterans’ Bureau agreed that plaintiffs would furnish water, in the manner presently detailed, to a hospital proposed to be located upon a site, the purchase of which by defendant was then under consideration, at rates applicable under city ordinances to consumers located within the city limits. After the agreement mentioned had been reached, defendant purchased the site and the construction of the San Fernando Hospital thereon was completed in the spring of 1926. The buildings of the hospital proper were all outside the city limits, but a portion of the site, on which water was also used, and certain facilities of the hospital, consisting of a pumping plant and water pipe line, were located within the city limits. The plan worked out and agreed to between plaintiffs and the Veterans’ Bureau for the obtaining by defendant and the furnishing by plaintiffs of water at within-city rates for the proposed hospital, was as follows:
The City of Los Angeles had a reservoir which was located approximately y2 mile within the city limits nearest to the hospital site. Due to the fact, which everyone knew, that it would be necessary to construct a pumping plant in order to get water to the hospital because the hospital site and grounds were higher than the city’s reservoir, it was agreed that the city would convey to defendant an easement in a plot of land approximately 50' x 50' located about 150 feet from the reservoir, and that, on this plot, defendant would at its own expense construct and operate a pumping plant and a 10-inch suction pipe line from the pumping plant to the reservoir over an easement, also to be granted and conveyed by the City.
It was further agreed that there would be constructed by the city from defendant’s pumping station to the corporate limits of the city nearest the hospital site, a distance of y2 mile, an 8-inch pipe line through which water pumped by defendant from the reservoir would be conveyed by the pumping plant to the hospital, the balance of this pipe line from the city limits to the hospital being furnished and constructed by defendant. It was also agreed that the entire cost and expense to the city of constructing this y2 mile of pipe line within the city limits would be assumed by defendant and *90reimbursed to the city by it, although title to this portion of the pipe line was to be in and belong to the city. The defendant paid $4,315.67 to the city for this section of the pipe line. It was also agreed that the meter for measuring the water sold by the city and used by defendant was to be furnished and installed by defendant at the pumping plant.
The conferences at which this plan and arrangement were worked out and agreed to by plaintiffs were for the most part with William Mulholland, the engineer of the Department of Water and Power, whose recommendations to that Department were always followed, but other officials of the City of Los Angeles, including the City Attorney, participated in some of the conferences with reference to the arrangements to furnish defendant with water at the within-city rate. There is evidence that various members of the City Council also participated in some of these conferences. The City Council was, at least from early in 1925, familiar with the plan and the arrangement between the parties. It was originally proposed and agreed that plaintiffs would grant defendant a license or permit and that defendant would furnish and construct over the city’s streets the y<¿ mile of 8-inch pipe line, above mentioned, from the pumping station to the city limits, along with the construction of the remainder of the pipe line to the hospital. Some question arose within plaintiffs’ organizations as to the propriety or legality of plaintiffs granting defendant a license or permit to carry out such pipe-line construction work over the city’s streets, and the matter was brought to the attention of the City Council. After consideration the Council, at a meeting on July 13, 1925, requested plaintiffs to grant defendant the permit. The Department of Water and Power granted the permit on the followTing day. This grant was subsequently considered to be ineffective and the arrangement hereinbefore set forth, under which plaintiffs constructed this section of the pipe line at defendant’s expense, was agreed to.
The above described plan and arrangement for the sale of water to defendant at plaintiffs’ reservoir at 5 cents per 100 cu. ft., were fully understood, agreed to, and consummated by written contracts. The first written contract was *91executed in October 1925. There was no fraud, mistake, or concealment on the part of anyone. Plaintiffs obviously considered and it is clear that they believed, at least from 1928 until November 1931, that under the broad powers granted to the Department of Water and F’ower by the City Charter and under the existing ordinances of the City Council it was proper and legal in the circumstances for the Board of Water and Power Commissioners to make the special arrangement which was made with defendant and to enter into the contracts in question to sell water to defendant at the city reservoir at the within-city rate of 5 cents per 100 cubic feet, rather than to charge for water so obtained the outside-city rate of 20 cents per 100 cubic feet based, as this last-mentioned rate was, upon facilities and services constructed, maintained, and supplied by the city. In this we think plaintiffs were right, and that the Board acted within the scope of its power and authority under the City Charter and under the Ordinances. Plaintiffs simply sold defendant water at the reservoir and “supplied” and “furnished” it within the city. In the circumstances the fact that this water, or most of it, was to be conveyed and used by defendant outside the city is not controlling and did not, in our opinion, render the plan agreed to and the contracts made pursuant thereto unauthorized or illegal.
As to the contention that the arrangement and the contracts made for the within-city rate were illegal and ultra vires, because they were not expressly approved by ordinances of the City Council, we think such express approval of the within-city ordinance rate agreed to was not necessary in the circumstances. However that may be, there is enough in the record to support the conclusion that the Council was fully aware of what was being done and the reasons therefor. It expressly acquiesced on two occasions, in February 1925 and January 1926, in the arrangements by which defendant was to obtain water, and we think the circumstances are sufficient to show that it impliedly acquiesced in and agreed to the use of the within-city rate which was an important and integral part of this arrangement.
On February 11, 1925, the Council adopted an ordinance which was approved by the Mayor February 16, 1925, au*92thorizing the granting by deed of an easement on oyer the plot of land near the reservoir for the construction and operation by defendant of a pumping station and pipe line connection to the reservoir “for pumping and filtration purposes.” At that time the Council must have known of the entire arrangement under which neither the City nor the Department of Water and Power was to furnish or supply any facilities or services for “furnishing” or “supplying water” outside the city limits. Under the plan and arrangements agreed to and the contracts made pursuant thereto, plaintiffs, as above stated, simply sold water within the city to defendant at the within-city ordinance rate, and it seems clear that everyone understood that this was what was being done. The parties proposed and agreed that defendant would go to the reservoir and get the water needed by it and convey it at its own cost and expense by proper means to its hospital and grounds for use both within and without the city. In effect there was a within-city sale of a commodity rather than the furnishing of the usual water facilities and services to an outside consumer. There is evidence that the ultimate cost to defendant of the water so obtained for the San Fernando Hospital was from 7y2 to 18 cents per 100 cubic feet.
Plaintiffs contend that the proper interpretation of the City Charter and the Ordinances in effect when the original plan and subsequent contracts were agreed to, is that the 'place of use of water, rather than the point of sale and delivery, must be the determining factor as to whether the within-city or without-city rate is applicable, but we think this contention overemphasizes the word “use” and leaves out of consideration the peculiar and special nature of the transaction, which, as we have said, was within the power and authority of the Department of Water and Power to conclude and carry out under the existing ordinances and the broad powers granted by the Charter. Moreover, part of the water, and probably a considerable part, purchased by defendant was actually used within the City. Plaintiffs make no allowance for this.
In the circumstances of this case we think the classification of defendant as a within-city consumer was within the power *93of tibe Board .Water it was proper.
Plaintiffs are therefore not entitled to recover the amount of $8,068.48 claimed with respect to water sold to the San Fernando.Hospital.
For water sold to defendant for use at the Sawtelle Hospital, plaintiffs- and .defendant agreed upon the within-city rate which was billed and paid without question from 1920 to November 1,1931. On November 1, 1931, and until January 1, 1932, plaintiffs claimed and billed defendant as for water furnished outside the city at 20 cents per 100 cubic feet, which defendant refused to pay and $8,111.15 is claimed on this account.
The facts with reference to this claim are set forth in findings 17 to 27. This' hospital was constructed prior to 1920 on a site purchased and owned by defendant containing 624.65 acres. This hospital and grounds are within the outer boundaries of the city but the site is not legally a part of or within the corporate limits of the city. It is for this last-mentioned reason that plaintiffs claim this hospital was an outside consumer and chargeable with the outside-city ordinance rate.
In 1920 the City of Los Angeles desired to obtain from defendant a right-of-way across the hospital grounds for the construction and maintenance of a pipe line for conveying water from its reservoir for distribution to consumers located in the portion of the city known as Westgate. The officials of the hospital representing defendant proposed that defendant would convey the desired right-of-way to plaintiffs on the condition that the city permit defendant to obtain water service at the within-city rate through connections with the proposed water main, or pipe line. Conferences and negotiations were had between authorized representatives of the parties as a result of which defendant’s offer was accepted by the city. The agreement was consummated and carried out. Defendant conveyed a permanent easement over the hospital grounds on December 29, 1920, on the condition that the service connections would be made and water furnished in accordance with the above-mentioned agreement of the parties. Plaintiffs constructed a 24-inch *94trunk pipe line across the grounds; made service connections therewith and furnished the hospital water at the within-city rate until a question as to the propriety and legality of this arrangement was raised by plaintiffs in November 1931. During the period 1920 to May 7, 1929, water was so furnished and paid for under the above-mentioned agreement without such formal written annual contracts as the parties executed in connection with the San Fernando Hospital. The first formal contract for the furnishing of water at the within-city rate was executed May 7, 1929, covering the period February 25 through the remainder of the fiscal year ending June 30, 1929. This contract gave defendant the right to renew it in accordance with all of its terms from year to year. It was so renewed for three succeeding years, the last renewal being until June 30,1932.
What we have hereinbefore stated concerning the San Fernando Hospital with reference to the power and authority of plaintiffs under the City Charter and Ordinances to make and enter into such an arrangement and contract, as is here involved, applies to this item of the claim. In the circumstances disclosed by the record we think this hospital was properly and legally classified by plaintiffs as a within-city consumer. The pipe line from which the defendant obtained water was a within-city facility of plaintiffs through which they supplied water to residents within the City at the within-city ordinance rate. Plaintiffs received from defendant a valuable consideration in the form of the right-of-way which enabled plaintiffs to give water service to other within-city consumers at less cost to the city, which had the effect of removing in considerable measure, at least, the main reason for the higher ordinance water rate for water and service supplied to outside-city consumers. Tonawanda Board & Paper Co. v. City of Tonawanda, 198 N. Y. App. Div. 760, 190 N. Y. Supp. 874. Pavilion Natural Gas Co. v. Hurst, 123 Misc. 477, 205 N. Y. Supp. 847. Village of Long Beach v. Long Beach Power Co., 104 Misc. 337, 171 N. Y. Supp. 824. Penn Iron Co., Ltd. v. Lancaster, 25 Pa. Super. Ct. 478.
Plaintiffs are not entitled to recover on this item of the claim.
*95We have decided plaintiffs’ claim on the merits and therefore find it unnecessary to discuss the defense of estoppel. It should be pointed out, however, that, as contended by defendant and as has been uniformly held in cases brought in this court, if the contracts in question as to both hospitals were illegal, ultra vires, and, therefore, void, plaintiffs can only claim on the basis of a promise implied in law, rather than in fact, or on the basis of quantum meruit for the value of water and services furnished. A claim based on a promise implied in law cannot be enforced against the United States in this court. Ida F. Braun, et al., v. The United States, 98 C. Cls. 176, 199, 200; 46 Fed. Supp. 993, and cases therein cited. There was no promise or agreement implied in fact that the outside-city ordinance rate would be paid by defendant. The record shows that plaintiffs carefully considered all phases of the agreements made, including the rate that was applicable in the circumstances. The rate to be charged and paid was, of course, the subject matter concerning which the negotiations and agreements were had and as to which the written contracts were made. When plaintiffs considered that approval of the City Council was necessary as to any phase of the subject matter under consideration, they obtained such approval. It is obvious that throughout the period subsequent to 1923 and at the times the contracts were made plaintiffs considered the matter whether the within-city or the outside-city ordinance water rate was applicable in the circumstances and whether the Board of Water and Power Commissioners had the power and authority under the Charter and the Ordinances to agree to the within-city rate. It is also obvious from the record that the Board came to the conclusion that it did have this authority. There is no substantial evidence that in the agreements arrived at with defendant and in the written contracts made pursuant to and in accordance therewith either party thought or considered that it was making a contract for payment by defendant of any rate other than the within-city rate. There is, therefore, no support for plaintiffs’ contention that the parties intended only to contract for payment by defendant of the “applicable legal ordinance rate” and that this was the outside-city rate. The *96conclusion by plaintiffs, as shown by the facts and circumstances, and the provisions of the formal contracts, that the Board of Water and Power Commissioners was acting within the scope of its authority, is entitled to great weight. The Board and the defendant expressly agreed to the within-city rate, and no other promise or contract by defendant for another or higher rate can be implied. Hawkins v. United States, 96 U. S. 689, 697, 698; Smithmeyer v. United States, 147 U. S. 842, 359.
If it were held, contrary to what we think, that the contracts for the within-city rate were illegal and, therefore, unenforceable by either party, plaintiffs would only be entitled to recover on quantum meruit for the fair and reasonable value of the water and service furnished, and there is no proof in the record that this would be in excess of the within-city contract rate paid. See Douglas Aircraft Co., Inc. v. United States, 95 C. Cls. 140, 147. The rate fixed by the parties and paid by defendant would seem to be a fair and reasonable value since the proof shows that plaintiffs did not, at their expense, furnish defendant with any of the facilities and services customarily furnished by plaintiffs to outside-city consumers. It is doubtless for this reason that plaintiffs make no claim on quantum meruit.
The petition is dismissed. It is so ordered.
