This сase involves another episode in the ongoing saga of disputes between the owner of a mill and the United States Environmental Protection Agency (EPA). An earlier episode is recounted in
United States v. Knott,
James M. Knott, Sr., and Riverdale Mills Corporation (“Riverdale”) sued two EPA inspectors, Justin Pimpare and Daniel Granz, alleging violations of the plaintiffs’ Fourth Amendment right to be free from unreasonable searches.
1
The plaintiffs allege that the agents’ sampling, without warrant or consent, of wastewater from underneath a manhole located on Riverdale land in Northbridge, Massachusetts, on the afternoon of Octоber 21, 1997, constituted a violation of the Fourth Amendment. The Fourth Amendment claim is pursuant to
Bivens v. Six Unknown Named Agents of Fed. Bureau of Narcotics,
Pimpare and Granz defended, inter alia, on grounds of qualified immunity; the district court denied their motion for summary judgment on grounds of qualified immunity, and they properly filed an interlocutory appeal. We reverse because, under the first prong of the qualified immunity test, Knott and Riverdale have no reasonable expectation of privacy in this wastewater under the circumstances shown in the record and therefore they have no Fourth Amendment right. Even were this ruling incorrect, we would reverse under the second prong, since the existence of such a reasonable expectation was not clearly established law. We remand for entry of judgment for Pimpare and Granz on qualified immunity grounds.
I.
Riverdale manufactures plastic-coated steel wire products. Knott is the company’s president, treasurer, chief executive officer, chairman of the board, and controlling shareholder. During manufacture of the product, a water-based cleaning process is used, and this cleaning process generates both acidic and alkaline waste-water. Riverdale has a state permit allowing it to put this wastewater into the public *57 sewer system so long as proper treatment (neutralizing the acidic or alkaline qualities of the water, amоng other things) has been applied before the wastewater reaches the public sewer.
In order to meet state and federal clean-water requirements, Riverdale has a pretreatment system within its plant which is supposed to treat and neutralize the acid or base qualities of the wastewater before it reaches the public sewer. After going through the pretreatment system, the wastewater flows through a meter loop where the quantity of wastewater is measured to determine the sewer charges that Riverdale must pay to the town of North-bridge. The wastewater then flows through a “test pit” outside of Riverdale’s plant (“Manhole 1”) toward the public sewer. 2
Manhole 1 is roughly twо feet deep and is covered by an unmarked 171-pound steel manhole cover. It is located on a paved street, Riverdale Street, that runs alongside the mill building. Pimpare noted in his affidavit that it “appears to be a public street.” Riverdale alleges that it privately owns this street, which runs from a public road (Route 122) across River-dale’s property along the northern side of the mill. The road dead ends, however, at a set of concrete barriers before a bridge on Riverdale’s property. On the Route 122 entrance to Riverdale Street, a sign reads “Bridge Closed — Local Traffic Only.” The road is actually on top of an earthen dam built by earlier owners of the plant and usеd to create a millpond opposite the Riverdale mill. Riverdale has alleged in its complaint that Riverdale owns Manhole 1; there is, as we found in a previous opinion, considerable reasonable dispute about whether this is so. See
Knott,
The plant’s wastewater flows past Manhole 1 through 300 more feet of pipe allegedly owned by Riverdale to Manhole 2, which is further down Riverdale Street. At Manhole 2, the Riverdale pipe carrying wastewater from Manhole 1 enters Manhоle 2 as a separate flow and merges with other flows within Manhole 2 (it is possible to sample Riverdale’s wastewater separately at Manhole 2 before it merges with the other flows). Manhole 2 is indisputably publicly owned and is part of the public sewer system. From there, the wastewater eventually flows to the Town of Northbridge treatment plant before being released into the Blackstone River.
On July 28, 1997, an anonymous tipster purporting to be a Riverdale employee sent a letter to the EPA alleging that the plant’s pretreatment system was not being run properly and thus that the plant might be discharging wastewater with improper pH levels and other problems.
The EPA decided to look into it. On the mоrning of October, 21, 1997, the Agency sent Pimpare and Granz to the mill to perform an inspection. The two inspectors did not obtain a search warrant, and there is no claim of exigent circumstances. Inspector Pimpare first met with Knott and two high-level employees; Inspector Granz *58 arrived sometime during that opening meeting. At that meeting, Pimpare did not assert any statutory authority to search Riverdale property but instead asked Knott to give his consent to an inspection of the wastewater treatment facility, including tests of the wastewater.
Both the complaint and Knott’s affidavit state that Knott “explicitly” told both Pim-pare and Granz that they could sample Riverdale’s wastewater and tour its plant only on the “express condition” that they be accompanied at all times by Knott or Riverdale employees designated by Knott. We accept the district court’s conclusion that Knott’s consent was given only on condition that the agents be so accompanied at all times.

See Knott,
That morning, right after the meeting, Pimpare and Granz were taken by Knott and the two Riverdale employees directly to Manhole 1, where the inspectors took samples from approximately 10:40 am to 11:15 am. One sample was provided to a Riverdale employee. This first sampling, then, was indisputably in conformity with Fourth Amendment requirements, if any are applicable, because it fell within the scope of consent.
The inspectors had earlier planned on setting up a 24-hour composite sample, but this was not done. The reason why this was not done is in some dispute. Pim-pare’s affidavit states that it was infeasible because of the intermittent nature of the wastewater discharges. He states that he told Knott this and “made it clear to Knott that Granz and [Pimpare] would be taking additional samples from the manhole throughout the day.” He says that Knott responded, “Okay.” Knott gives a different account. His affidavit states that Pimpare told him 24-hour composite sampling would be a bad idea because it would be unsafe to leave the equipment in the street. Knott says he offered the agents some accommodations to fix this problem, which were declined. Knott states that he was never told that the inspectors were going to conduct periodic sampling throughout the day.
After conducting this initial round of sampling at Manhole 1, Pimpare states that he and Granz were taken on a tour оf the mill by Knott and the two employees. Pimpare states that at the conclusion of this tour, he again told Knott and the two employees that he would need to conduct more testing at Manhole 1; he asserts that Knott did not object. Knott disputes that Pimpare told him the agents would need to conduct more tests at Manhole 1.
In any event, Pimpare and Granz took samples from Manhole 1 during two additional intervals that afternoon: between 12:40 pm and 1:15 pm, and between 3:00 pm and 3:04 pm. These sampling events are the crucial ones for purposes of this appeal. Knott states that Pimpare and Granz took these samples without him or any of his representatives present, and thus that this afternоon sampling exceeded the scope of his consent. The inspectors concede that no Riverdale representatives *59 were present for this sampling. The sampling occurred, however, on the street in front of the plant and in full view of River-dale employees. Id. at 23. A sample from the 12:40 pm to 1:15 pm testing was given to one of the Riverdale employees, who signed a chain of custody form. Id. at 24. Before leaving the area that day, the inspectors also took samples from Manhole 2.
The data resulting from the October 21 sampling led the EPA to obtain an administrative search warrant and to search the facility pursuant to this warrant on November 7,1997. A second, criminal search warrant was executed on July 19, 1998. These later searches are not at issue in this appeal; only the October 21, 1997 afternoon sampling is relevant.
II.
Riverdale and Knott were indicted by a grand jury on August 12, 1998, based on evidence found in these searches, for two counts of violating the Clean Water Act, 33 U.S.C. § 1251
et seq.,
by discharging industrial waste into publicly owned treatment works in violation of a national pretreatment standard for pH levels.
See
33 U.S.C. §§ 1317(b)(1), 1319(c)(2)(A); 40 C.F.R. § 403.5(b)(2). Knott and Riverdale moved to suppress evidence obtained during the October 21, 1997 and November 7, 1997 searches. The district court granted the motion in part: it determined that the afternoon sampling on October 21 had exceeded the scope of Knott’s consent bеcause neither Knott nor a designated Riv-erdale employee had been present. It thus suppressed the fruits of those afternoon searches but declined to suppress any evidence obtained on November 7.
Knott,
The district court then granted a motion by Riverdale to recover reasonable attorneys’ fees under the Hyde Amendment on the grounds that the prosecution against it had been vexatious.
United States v. Knott,
Knott and Riverdale then brought this civil action in federal district court for damages, based on alleged constitutional violatiоns, against the United States, Pimpare, Granz, and another EPA agent, Stephen Creavin. On March 16, 2004, the district court denied Pimpare’s and Granz’s motions for summary judgment on the grounds of qualified immunity.
Riverdale Mills Corp. v. United States,
On the first prong of the test, the district court held that Riverdale’s allegation that Pimpare and Granz exсeeded the scope of Knott’s consent to the October 21 search of wastewater in Manhole 1, if true, constituted a violation of Riverdale’s Fourth Amendment rights.

We have jurisdiction over an interlocutory appeal from a denial of qualified immunity, where, аs here, the denial rests on purely legal questions and not on disputed issues of fact.
Dwan v. City of Boston,
Qualified immunity provides “an entitlement not to stand trial or face the other burdens of litigation.”
Saucier v. Katz,
As most recently explained by Justice Breyer in his concurring opinion in
Bros-seau v. Haugen,
the test laid out in
Saucier
has two basic parts:
“Saucier
requires lower courts to decide (1) the constitutional question prior to deciding (2) the qualified immunity question.” - U.S. -,
On the third prong, we ask whether a “reasonable officer, similarly situated, would understand that the challenged conduct violated” the clearly established right at issue.
Id.
It is not always evident at the time an official takes an action that a clearly established right is involved. For example, the factual situation might be ambiguous or the application of the legal standard to the precise facts at issue might be difficult; in either cаse the officer’s actions may be objectively reasonable and she may be entitled to qualified immunity.
See Saucier,
The First Prong
The Supreme Court has stated that courts should begin with the first prong, that is, whether the facts as seen in the light most favorable to the injured party show that the officers’ conduct violated a constitutional right.
See Saucier,
The issue of how specific the first prong is meant to be is an issue that has troubled courts for some time.
See Tremblay v. McClellan,
The level of specificity depеnds on the stage of the proceedings at which a qualified immunity defense is brought. A qualified immunity defense can, of course, be brought as a Fed.R.Civ.P. 12(b)(6) motion for failure to state a claim upon which relief can be granted. In such a case the entire qualified immunity analysis, including the first prong, must be based only on the facts stated in the complaint itself.
See, e.g., Butler v. San Diego Dist. Attorney’s Office,
Where, as here, qualified immunity is brought at the summary judgment stage, the inquiry on the first prong is somewhat different. The language in
Saucier
is ambiguous on this point; the case refers both to “the facts alleged” and to the “parties’
*62
submissions.”
We emphasize that the rule stating that the first prong must be performed before the rest of the qualified immunity analysis is not completely inflexible. The purpose of starting with the first prong is to aid in law elaboration.
Saucier
itself suggests that this law elaboration functiоn will be well served only in “appropriate cases,”
Nonetheless, it is clear that when performing the first prong of the analysis, it is generally inadequate to state a very generalized proposition such as whether it is a constitutional violation for enforcement officers to perform an unreasonable search.
See Int’l Action Ctr. v. United States,
In this case, Granz and Pimpare have raised the qualified immunity defense on summary judgment and not as a 12(b)(6) motion. We take it as undisputed at this stage that the agents lacked a warrant and that they exceeded the scope of Knott’s consent. 7 These issues, however, go only *63 to the “reasonableness” of any Fourth Amendment “search.”
The threshold issue is whether there was a “search” at all for Fourth Amendment purposes. Granz and Pimpare’s actions were only a “search” if Riverdale had a reasonable expectation of privacy in the wastewater underneath Manhole 1.
See Kyllo v. United States,
The key issue for the first prong, then, is whether Riverdale, based on the undisputed material facts and any disputed material facts looked at in its favor, had an objectively reasonable expectation of privacy in the wastewater underneath Manhole 1. More specifically, our inquiry is whether a company has a reasonable expectation of privacy in industrial wastewater that is on a private street and underneath a 171-pound manhole cover but 300 feet away from and flowing irrevocably into the public sewer system.
The EPA inspeсtors urge that we adopt a per se rule that there is never a reasonable expectation of privacy in wastewater. This we decline to do. Judgments about reasonable expectations of privacy are very fact-specific, and there may be fact situations where wastewater is entitled to constitutional protection.
See Dow Chem. Co. v. United States,
The trash cases that the agents cite also do not support their per se rule. These cases dо not establish that trash can never be protected for Fourth Amendment purposes; rather they hold only that trash left in bags on or near the curb for collection by a third party is unprotected.
See, e.g., California v. Greenwood,
Whether there is a reasonable expectation of privacy depends on a variety of factors in addition to the character of the substance as wastewatér. The commercial context is relevant; this may reduce River-dale’s expectation of privacy somewhat.
See Dow Chem. Co.,
The fact that Manhole 1 is on private property is relevant, but that fact alone does not resolve the issue one way or the other. The contours of the Fourth Amendment are not cotеrminous with property and trespass law.
See Oliver v. United States,
Ultimately, we conclude that the controlling fact here is that the wastewater at Manhole 1 is
irretrievably
flowing into the public sewer, which is only 300 feet away. The wastewater will inevitably reach Manhole 2, where the public sewer begins, after only a short period of time, and once it reaches that point, any member of the public can take a sample. Wastewater at Manhole 1 under these circumstances is similar tо trash left out on the curb for pick-up by the trash collector, which enjoys no reasonable expectation of privacy, even if left in opaque bags.
See Greenwood,
It is true that a passerby cannot as easily sample wastewater while it is underneath Manhole 1 as he can pick through garbage. However, because the wastewa-ter will assurеdly enter the public sewer and will flow there so quickly, the trash analogy controls even if it is not exact. Plaintiffs make an implicit argument that they should be able to expect privacy up until the point at which their wastewater can no longer be differentiated from the other sewage flows. This argument misfires. Riverdale had no cut-off valve at Manhole 1, and thus no way to stop the irretrievable flow to the public sewer. On these facts, Riverdale has abandoned any reasonable expectation of privacy in the wastewater by allowing it to flow irretrievably into a place where it will be “exposed ... to the public.”
Id.
at 40,
Riverdale relies heavily — and incorrectly — on the Massachusetts Supreme Judicial Court decision in
Commonwealth v.
*65
Krisco Corp.,
By contrast, a manhole cover is normally intended less to keep people out than to provide them access: the manhole cover, even if heavy, is one of the few poitots from which an underground sewer can be reached. Moreover, a manhole cover, unlike a gate or fence, is not intended to leave passersby ignorant as to the contents within. Fences might hide any number of highly private objects; manholes, however, generally give access only to a few sorts of things, most commonly a sewer (or underground wires or pipes). Placing otherwise unprotected wastewater underneath a manhole cover does nоt create a reasonable expectation of privacy where one did not exist before. At any rate, the trash in Krisco, which was being held stationary behind the gates for pickup, is quite different than the wastewater here, which is not being held within Manhole 1 but rather is flowing through it on its way to the public sewer.
We hold that based on the summary judgment record and using the normal summary judgment standard, Riverdale’s Fourth Amendment rights were not violated and the agents are entitled to qualified immunity on the first prong. We thus need not reach the other two prongs of the qualified immunity analysis; we address the second prong merely as an alternative ground for decision, should we be wrong on the first prong.
The Second Prong
The second prong asks whether the constitutional right that the officer allegedly violated was “clearly established” at the time of the incident such that it would “be clear to a reasonable officer that his conduct was unlawful in the situation he confronted.”
Saucier,
This does not mean that the facts of prior cases must be materially similar, but
*66
merely that the prior case law must give the officer reasonable notice that the specific conduct she is alleged to have committed in this litigation is unlawful.
See Hope,
The district court below erred by posing the second prong as whether “the law regarding the necessity for a search warrant is clear.”
Riverdale Mills Corp.,
The law did not clearly establish any such Fourth Amendment right. We have found no court decisions holding that there is a reasonable expectation of privacy in industrial wastewater on its way to a public sewer. The law goes the other way.
9
The most obvious analogy, as we have noted, is between solid waste left out for the trash collector, for which there is usually no reasonable expectation of privacy, and liquid waste flowing into the public sewer system.
See Greenwood,
IV.
The district court’s denial of qualified immunity to Pimpare and Granz is reversed, and the case is remanded for entry of judgment in their favor. Costs are awarded to Pimpare and Granz.
Notes
. Riverdale also sued a third EPA agent, Stephen Creavin: the district court granted Creavin qualified immunity.
Riverdale Mitts Corp. v. United States,
. Manhole 1 is referred to as a "test pit" by both sides. There is evidence that Knott allowed regulators to test there in the past. A September 8, 1987 letter from Knott to the Chairman of the Town of Northbridge Board of Sewer Commissioners refers to a "pit” that is apparently Manhole 1 and states that "[t]his pit should be all that is needed to do whatever the Sewer Department might ever need to do with respect” to Riverdale's waste-water discharge.
. The agents' brief concedes that Knott imposed this condition. Pimpare stated in an affidavit, however, that he understood Knott merely to be indicating that Knott and the Riverdale employees would "walk [Pimpаre and Granz] around the premises,” not that they needed to be present for any inspecting to occur.
. In the same opinion, the district court granted Creavin, who did not conduct sampling on" October 21, qualified immunity on the grounds that he did not violate Riverdale or Knott's Fourth or Fifth Amendment rights.
Riverdale Mills Corp.,
. However, the second and third prongs have occasionally been combined into one step in this circuit.
See Tremblay v. McClellan,
. Indeed, three Supreme Court justices expressed concern in a recent concurrence that a rigid application of the
Saucier
rule — that the first prong must be decided before the rest of the qualified immunity inquiry — was unwise because of its tendency to lead to wasted judicial resources and to constitutional decisions that were insulated from judicial review. These justices thus asked that the rule be reconsidered.
See Brosseau,
. Pimpare and Granz do not argue that Riv-erdale is a "pervasively regulated business” that can be searched for this purpose without a warrant.
See New York v. Burger,
. Similarly, Riverdale argues that the right that needs to be clearly established is the constitutional requirement of a search warrant for a commercial establishment, as set forth in
See v. City of Seattle,
. One state court held that there was not a reasonable expectation of privacy in wastewa-ter that was probed from a manhole within a company’s plant, where that wastewater was flowing into the public sewer system.
