The chief justice was hearing a petition filed by Advocate Shahab Usto in the Supreme Court Karachi registry against the authorities for their alleged failure in providing clean drinking water and environment to the people in Sindh.
He claimed that almost 80 million people had hepatitis because of drinking polluted water.
The SC had then appointed a two-judge bench, headed by Justice Amir Hani Muslim, who had ordered the formation of a commission headed by a Sindh High Court judge for fair distribution of drinking water in the province.
Chief Minister Sindh Murad Ali Shah, however, had last month raised concerns over the commission formed by the SC.
"Let judiciary take care of its own work.
"It is the government’s responsibility to provide clean water to the public," Justice Saqib said, inquiring about what elected officials had been doing regarding the matter.
Sindh’s health secretary, chief secretary, home secretary, and managing director of water and sewage appeared in court along with other high-ranking officials.
The chief justice ordered the Sindh CM and former Karachi mayor to appear in court — the former will appear on Wednesday while the latter will appear tomorrow.
"Water is one of the resources that our country is blessed with," the chief justice remarked.
"We need to protect our resources."

Negligence of traditional methods led to water scarcity, says expert.
“We must start a dialogue with the Government for identifying, demarcating and notifying the water bodies.
In every state, the cause of ill-maintained waterbodies is different.
In Tamil Nadu it is encroachment.
It can be tackled if the government starts documenting the waterbodies.
The traditional crop patterns are failing due to the state of the waterbodies.
“To conserve the natural resource—water better, we must roll back to the ancient system of storing which is seven centuries old,” pointed out the recipient of Ramon Magsaysay Award and Stockholm Water Prize.
The introduction of water extraction techniques by the bureaucracy, change in the paradigm of development, state’s ownership of what is meant for the community to work on, disintegration of community institutions, creation of dependency syndrome which makes the government interfere into the issue and negligence of traditional methods for conserving the water are the foremost reasons for the drought.
In addition, the speaker emphasised on maintaining a balance between recharging the groundwater while we discharge.
“To make Tamil Nadu drought-free”, he said, “We must start interacting with people who deal with the resource, be it for exploiting, polluting or whatsoever the reason, and try to understand it better.

Preston Mulligan has been a reporter in the Maritimes for more than 20 years.
Court documents show 13 plaintiffs claim the town was negligent in its management of the site "in a matter that has caused pollution and environmental damage to ground and surface water, soil and aquatic life."
Was a sawmill tank drained properly?
In the court documents, the plaintiffs say the source of the contamination comes from the old 246,000-litre dip tank on the sawmill site.
Councillor Clifford Hood, chair of the town’s water utility, said while there may be contamination on the old sawmill site, he doesn’t believe it’s spreading to neighbouring properties "Our position is that we have not caused any of the allegations that are being made by those plaintiffs," said Hood.
Contamination ‘not moving’: councillor The community’s fear of contamination began to grow last year when the town spread garbage-filled compost over the former sawmill site.
But residents saw trash in the compost in early 2016 and complained.
They determined the compost wasn’t a source of contamination.
They also allege the contamination on the sawmill site made its way into the well water of three of the plaintiffs listed.
According to the court documents, several of the plaintiffs received a notice from the town in June of 2016 indicating that "contamination is known or suspected to directly impact surface water or sediment on the plaintiffs properties."

Honeywell will have to face class claims for negligence, nuisance, trespass and medical monitoring in a New York water contamination case, the Northern District of New York ruled Feb. 6 ( Baker v. Saint-Gobain Performance Plastics Corp. , 2017 BL 34914, N.D.N.Y., No.
The ruling came in closely-watched litigation over pervasive PFOA contamination in the town’s water supply, and the U.S. District Court for the Northern District of New York wrestled with unsettled issues of New York tort law in its decision.
“This is a wonderful decision for the people of Hoosick Falls, who may now proceed with their lawsuit,” Robin Greenwald, of Weitz & Luxenberg in New York City told Bloomberg BNA Feb. 7.
“The court also invited the parties to appeal the decision, and we are presently considering our appellate options,” Pokedoff said in an e-mail.
Private water well owners also have a possessory interest in wells harmed by PFOA trespasses, and private nuisance claims may proceed because of the “special loss” well owners suffer from the installation of monitoring equipment, the court said.
It did, however, dismiss private nuisance claims brought by municipal water users.
Those plaintiffs presented public, rather than private, nuisance considerations, the court said.
Medical Monitoring Claims The companies also argued New York law barred medical monitoring claims brought by Baker and other plaintiffs with elevated PFOA levels, at least where there is no existing diagnosis.
There are “several complex and novel issues of New York law as to which the existing case law is significantly muddled,” and they warranted an immediate appeal of the order to the Second Circuit.
The law offices of Weitz & Luxenberg represented the plaintiffs.
