Appellants brought this suit in the Lake Circuit Court seeking to enjoin the city of Hammond, certain of the officers of said city, and the contractors from carrying out a contract entered into between the city, through its board of public works, and the contractors for the construction of a pumping station and a system of sewers to connect therewith. The record discloses that the improvement contemplated included a pumping station located on the north bank of the Grand Calumet river, a main sewer to connect therewith and extend in a northerly direction together with certain connecting collateral sewers, and also a main sewer to extend south from the pumping station and to be connected therewith by means of a siphon constructed under the river together with certain collateral sewers to connect with the main sewer extending south. It appears that the entire work was treated by the city as a single public improvement. The board of public works fixed the boundary limits of the deep sewer system and filed a map showing the territory to be benefited thereby and took such further steps as resulted in the establishment of a drainage district including about half of the area of the city of Hammond, a part of which district is located on the north side of the *616Grand Calumet river, and a part of which is located on the south side of that river. The pumping station was designed and intended to furnish power to operate pumps and also to provide means for treating and disposing of the sewage in a sanitary manner. The specifications provided that the pumping station and machinery and each and all of the sewers should be bid on and let as one contract and the contract was so let.
It is the theory of appellants that the benefits which will result from the construction of the sewers provided for are not common to all real estate situated within the district for the reason that the sewers to be constructed on opposite sides of the river would have no connection except that the pumping station is intended to pump the sewage from both. It is asserted that the board of public works has no power to join several sewers and a pumping station in one proceeding and to make assessments for the cost thereof on a common district as proposed in the proceeding which is attacked.
A trial resulted in a finding and judgment denying the injunction. Appellants filed a motion for a new trial based upon the insufficiency of the evidence to sustain the decision of the court and upon the ground that such decision was contrary to law. The court overruled this motion, which ruling is assigned here as the only error relied on.
1. It is well settled that the acts of municipal bodies performed within the scope of their powers and free from fraud are not open to collateral attack. McEneney v. Town of Sullivan (1890), 125 Ind. 407, 25 N. E. 540. In that case the court said: “The attack made upon the proceedings of the corporate officers is a collateral one, and it is well settled that upon such an attack only defects or irregularities affecting the jurisdiction can be made available.”
*6172. Appellants attack this proceeding on the ground of fraud and also upon the ground that the city, in an attempt to exercise a power granted, did not proceed in the manner prescribed by the statute. Whether a power has been executed in the manner directed by the statute presents a question in its nature jurisdictional. “If the municipality attempts some method other than that provided by the statute, or goes beyond the authority given, to that extent, it is without jurisdiction and its acts are void.” City of Bluffton v. Miller (1904), 33 Ind. App. 521, 70 N. E. 989.
3. The issue of fraud presented by the allegations to the effect that the city of Hammond through its board of public works was providing an electric light and power plant for the city under the guise of erecting a pumping station was denied, thus presenting a question of fact. Upon this issue the finding of the trial court was against appellant and, as there is evidence to support such a finding, it cannot be disturbed on appeal.
4. *6185. *617The question of fraud being thus disposed of, we are now to consider the power of the city through its board of public works to order the proposed improvement and to assess the cost thereof against the real estate benefited as proposed in this proceeding. In determining what powers the legislature had granted to cities in this regard we are required to look to the statutes on the subject. The power to assess the costs of improvements against the real estate benefited does not exist in the absence of a statute granting such power, and when granted, the extent of the power is limited to that which the statute expressly confers. Klein v. Nugent Gravel Co. (1903), 162 Ind. 509, 70 N. E. 801; Indiana Union Traction Co. v. Gough (1913), 54 Ind. App. 438, 102 N. E. 453; Darby v. Vinnedge *618(1913), 53 Ind. App. 525, 100 N. E. 862. Statutes on this subject are strictly construed in favor of the property owner, and in case of doubt as to the existence of the power, the doubt is resolved against the municipality. Adams v. City of Shelbyville (1899), 154 Ind. 467, 57 N. E. 114, 49 L. R. A. 797, 77 Am. St. 484.
6. The first matter for consideration is the power of the city to construct a pumping station in connection with several main and collateral sewers in one proceeding providing for one entire assessment district. Appellants concede that any city has power through the action of its common council to build a pumping station in connection with a general system of sewerage adapted to drain the entire city, and to provide for the payment of the cost of such general sewer system and pumping station by the issue of bonds of the municipality to be met by a fund to be provided by general tax levies as provided by §8961b Burns 1914, Acts 1909 p. 187. This section provides that no such improvement shall be made unless authorized by a majority vote of the qualified voters of the municipality to be taken in accordance with the terms of the statute. This section by its express provisions applies only to such cities and towns as are sufficiently level that the entire municipality may use such general system. Appellees do not claim that the proceedings for the construction of the improvement here under consideration rest upon this statute, and the section is mentioned only because of appellants’ claim that an improvement such as this can be constructed, if at all, only in accordance with its provisions and at the cost of the entire municipality ; and that there is no statutory authority for assessing the cost of such an improvement, as a whole, against the property benefited. Appellants do not deny that cities have power to order the construction of *619sewers and assess the cost of the same against the property benefited in accordance with the provisions of our statutes on the subject. §8722 et seq. Burns 1914, Acts 1905 p. 219, 302. They do assert, however, that these statutes require a separate proceeding for each sewer constructed, and that they do not authorize the building of a system of sewers, consisting of several sewers located on separate streets and connected with a pumping station and disposal plant, in a single proceeding, as here proposed.
7. *6208. 9. 10. *619The legislature in 1905 made provision for the building of two classes of sewers- — one a local sewer for the benefit of abutting property only, the other a larger sewer intended and adapted to receive sewage from connecting or collateral sewers already in existence or which may be constructed in the future. §8722 Burns 1914, supra. When the proceeding contemplates a local sewer only, no drainage district is required to be formed as the improvement is intended to benefit the abutting property only; but when the proceeding contemplates the construction of a sewer adapted to receive sewage from connecting collateral sewers the statute provides for the formation of a drainage district including the territory which will find an outlet through such sewer by means of the connecting drains already in existence and those to be subsequently constructed. The legislature evidently contemplated that all of the lots and parcels of land included within the district to be so formed would be benefited by the construction of the sewer provided for in the proceeding for the reason that it provided an outlet through connecting collateral sewers already in existence, or that it would provide such an outlet when other such sewers were constructed. It was deemed proper by the legislature that a part of the cost of the construction of the main sewer should be imposed upon *620all lots and parcels of land situated within the .district and which would find an outlet through it by means of connecting sewers. The section of the statute with reference to making the primary assessments to pay the cost of constructing a sewer which is adapted to receive drainage from connecting' sewers provides that the cost of such sewer shall be divided and that so much of the cost as would have been necessary to provide an adequate local sewer for the property abutting thereon shall be assessed against such abutting property, and that the remainder of such cost shall be primarily assessed against all of the lots and parcels of land included in the drainage district. §8724 Burns 1914, supra. From a consideration of these statutes it seems clear that the legislature did not intend that any lot or parcel of land should be assessed to pay the cost of any main sewer adapted to receive drainage from connecting collateral sewers unless such lot or parcel of land was benefited directly as abutting property, or indirectly by reason of the fact that such sewer was calculated to afford it an outlet by means of a collateral sewer then in existence or to be thereafter constructed. As before stated, the improvement contemplated' by this proceeding consists of a pumping station on the north bank of the Grand Calumet river, together with a sewer connecting therewith and running north therefrom and also a sewer connected therewith by a siphon under the river and extending in a southerly direction therefrom. The sewer planned to extend north from the pumping station is adapted to receive sewage from collateral sewers and is calculated to afford an outlet for that portion of the sewerage district established in this proceeding which lies north of the Grand Calumet river but it could never possibly be utilized as an outlet for any of the portion of such district which lies *621south of that river. The main sewer which is planned to extend south from the pumping station is adapted to afford an outlet by connecting sewers to that portion of the sewerage district lying south of the river but it could never be used as an outlet for any portion of the district lying north of the river. As applied to the situation presented by this record, the statute clearly requires that the cost of the improvement to be constructed south of the river should be assessed against a sewerage district lying south of the river and including the territory which will find an outlet from that direction and that no part of the cost of such improvement should be assessed against any lots or parcels of land lying north of the river for the reason 'that no benefits could accrue to the lands north of the river from the construction of sewers which would not either directly or indirectly afford them outlet. For the same reason the statute requires that a separate drainage district be formed north of the river including the territory which will find an outlet through the main sewer to connect with the pumping státion from the north. Unless the main sewer extending north from the pumping station and the main sewer extending south therefrom are constructed under separate proceedings necessitating a separate drainage district for each, it is apparent that the assessments cannot be made and apportioned as to the lands benefited in the manner contemplated by the statute. If both of these sewers were to be constructed in one proceeding and the drainage district formed were to include all of the territory drained by both,' it is apparent that an attempt to make the assessments in conformity with the statutes would result in assessing a part of the cost of the improvement lying south of the river on all of the real estate located within the drainage district including that on the north of the river as well as that on the south, and vice versa. *622A consideration of the statute as a whole shows that the legislature did not intend that any real estate should be assessed to pay any part of the cost of a sewer to be constructed under the act unless such real estate would be benefited directly as abutting property or indirectly by finding an outlet through such sewer.
11. 12. Proceedings for the construction of sewers must be of such a character as to enable the board of public works to make the assessments and to apportion them in accordance with the statute. No proceeding is authorized which would result in the fixing of the assessments in a way other or different from that provided in the act, or which would result in assessing any real estate for any part of the costs of th° construction of a sewer which would not either directly or indirectly afford an outlet for its sewage. A drainage district to be formed in the construction of any sewer should include all territory which will ultimately find an outlet through it, and no other; and the fact that in this cáse the portion of the drainage district which drains from the north is separated from that portion which drains from the south by a river, is not decisive of the question.
Appellants assert that any construction of the statute that would authorize assessments to be made against real estate to pay a part of the cost of constructing a sewer that would not either directly or indirectly afford it an outlet for drainage would amount to the taking of property without due process of law. In view of the construction placed upon the statute by this opinion the court is not required to decide the constitutional question thus presented. The constitutional question is referred to as showing jurisdiction in this court.
*62310. *622The court accordingly holds that two main sewers on opposite sides of a river draining separate and distinct *623territory cannot be constructed under our statute in a single proceeding and the costs thereof assessed against the real estate within a district so formed as to include the territory drained by both, a part of which lies on each side of the river.
Appellees cite Lewis. v. Albertson (1899), 23 Ind. App. 147, 53 N. E. 1071, and rely upon it as authority for the proposition that two or more separate public improvements may be constructed under one proceeding. In that case it appears that the common council by resolution declared the necessity of improving H street, and in the same resolution declared the necessity of improving I street. Later by one resolution the common council ordered the improvement of H street from Fifteenth street south to the city limits and of I street from Sixteenth street to the city limits. In an action to enforce an assessment the court held that such assessment was not void for the reason that two separate streets were improved in a single proceeding. It will be observed that the cost of street improvements under the statute in force were assessed against the property abutting on the streets improved and no other. Assessments in such proceedings do not require the formation of assessment districts such as the statutes governing a proceeding of the kind here involved require; and therefore the fact that a single proceeding included the improvement of two separate streets would not in any way interfere with the assessment of the benefits in the manner provided by the statute as it would do in the proceeding here under consideration. The attention of the court is also called to a number of decisions by courts of other states; but, as it is not shown that the statutes under which those decisions were made were in any respect similar-to those which govern the decision of •this case, they cannot be regarded as controlling.
*62413. *623The court does not hold that there is a lack of power *624to construct the work contemplated by this proceeding and. to assess the cost against the property benefited. The holding is that the proceedings do not conform to the requirements of the statute. Because there is an attempt to exercise a power in a' manner essentially different from that provided by the statute, the attempted proceeding must fail. There can certainly be no doubt that the city has power under statutes to construct the contemplated improvement in all its parts and to assess the cost against property benefited if it proceeds in accordance with the terms of the statutes on the subject. It is suggested that there is no power granted to construct a pumping station at the cost of the property benefited but that such an improvement must be paid for by a general municipal tax. As to this appellants are clearly in error. Section 8696 Burns 1914, which is §93 of the Cities and Towns Act of 1905, supra, as amended in 1909, provides that the board of public works shall have power “to lay out, design, order and contract for and execute the construction, alteration, and maintenance of all public drains or sewers within such city, * * * and to erect, maintain and operate works for the collection, treatment and disposal of sewage.”
By this section power to construct a pumping station was expressly granted to the city to be exercised by its bpard of public works, but no method is provided by that section for the exercise of the power. A later section of the act of 1905, which is §8965 Burns 1914, Acts 1905 p. 219, 409, provides that, where a power is granted by any section of the act to any officer or board and no method provided for the exercise of the power, and where provision is made by any other section of the act, or by any other law of the State, for the exercise of such power or similar power, which is applicable to the exercise of the authority so granted, then such other *625section or other law, in so far as the same provides a method for the exercise of the power, may be followed as fully as if incorporated in and made a part of the section'granting such authority or power. The power to construct sewers and to build sewage pumping stations are similar powers both granted by clause 7 of §8696 Burns 1914, supra. The legislature, having provided a method for the exercise of such power in respect to the construction of sewers, that method may be followed in the erection of a pumping station. No doubt the cost of the erection of such a pumping station can be assessed against the real estate to be benefited thereby to be included within a district to be formed for that purpose in accordance with the provisions of §8724 Burns 1914, supra.
The conclusion thus reached is strengthened by a consideration of §7599 Burns 1914, Acts 1909 p. 60, 62, by the terms of- which all cities and towns are given power to provide the means for payingthe cost of constructing plants for the purification of the discharge of sewers by assessing the cost thereof against all of the real estate situate within the corporate limits, such assessments to be in an amount not greater than the benefits received by each separate parcel, respectively, by reason of the construction of such plant. The statutes for the construction of public sewers and assessing the cost of the same against real estate in such municipalities are expressly made applicable so far as they can be to the construction of sewage purification plants and the assessing of the cost thereof against the real estate benefited thereby.
14. Another question is presented as to the power of a city under our statutes to construct a main sewer and one or more connecting lateral sewers as one work and under a single proceeding. *626From what has been said, it would appear that the solution depends upon the character of the connecting lateral sewer. If it is purely a local sewer the costs of which must be assessed entirely against abutting property, no reason is apparent why such a collateral might not be constructed in the same proceeding and as a part of the main sewer; but if the connecting sewer is one intended to receive sewage from other connecting sewers the cost of which, under the statute, is required to be divided in making the assessment and the portion in excess of the cost of a local sewer, apportioned among the lots and parcels of land for which it furnishes an outlet, then it would appear that a separate proceeding would be required involving the formation of a subordinate sewage district including the territory to which it affords an outlet; otherwise the assessments could not be made and apportioned as the statute (§8724 Burns 1914, supra) requires.
The record presents several other questions; but, in view of the conclusion reached it is not deemed necessary to consider them. What has been said is sufficient to show the construction which the court places on the statute and to indicate that the decision of the trial court is contrary to law. The judgment is reversed, with instruction to sustain appellants’ motion for a new trial.
