Meet the State Water Commission

State Water Commission

In August 1992, with the promulgation of the Urban Code for the State of Querétaro, the 24th Article  clearly established that CEA would be:

“The organization that coordinates and assists  federal, state, or municipal authorities with all activities that in one way or another are associated with planning, studies, projects, construction and operation of potable water piping systems, drainage and sewerage, for the benefit of the inhabitants of the state.”


“Coordinate and assist water sector development in the entity, ensuring the provision of quality service for the benefit of Querétaro’s population, in an environment of social participation and respect for the regulatory framework.”


“To be leaders in the potable water sector, applying efficient and effective work methods and infrastructure using qualified personnel and modern technologies.”

Water Culture

Teaching “Water Culture”

A continuous process, updating individual and collective values, beliefs, perceptions, knowledge, traditions, skills and behaviors related to the everyday, rational and efficient use of water.

The State Water Commission focuses on these issues to achieve positive and proactive change in individual and collective participation in the goal of sustainable water use, promoting communication and ensuring adequate water supply for future generations.

School program

– We teach “Water Culture” in elementary, middle and high school classes.
– We promote tours to our facilities and to our water treatment plants.
– We support ecological events organized by USEBEQ (Service Unit for Basic Education in Querétaro), and Environmental Weeks of different institutions.
– We offer Environmental Education training for teachers and for “Water Culture” promoters.

Community Program

– We participate in fairs, expositions and cultural weeks in the State.
– We offer to teach “Water Culture” in companies, and promote the use of water-saving devices.
– We organize various events to celebrate important dates, such as the World Water Day.

Saving Water Tips

1st Tip – If you wash your car use one bucket of water instead of using the hose.

2nd Tip – Taking showers rather than baths will save an average of 7,300 liters of water per year.

3rd Tip – Wash your teeth with a glass of water and rinse your tooth brush with a minimum amount of water.

4th Tip – Repair leaks immediately, a small leak that produces a drop per second wastes 4,320 liters of water per year.  Also make sure that water taps are closed.

5th Tip – Never use the hose when you can use a broom.

6th Tip – Use washing machines and dishwashers with maximum loads and reuse greywater for irrigation or flushing the toilet.

7th Tip – Check periodically for leaks in the toilet, paying special attention to the toilet float and flush valve.

8th Tip – To check if there are leaks in the flush valve, place some colorant in the tank and if colored water passes, there’s a leak!

9th Tip – Keep children from playing with hoses or otherwise wasting water.

10th Tip – Check and change broken or worn pipes, fixtures, and valves.

Water Supply’s History in the City

Water in Querétaro’s History

The colonial system of drinking water distribution in Querétaro consisted mainly of an aqueduct and a distribution network of terracotta pipe. The system remained in service with few changes until the end of the 19th century; a century and a half after it was installed by the Marquis of the Villa del Villar del Águila.

In 1894 Eng. Francisco González of Cosío became Governor of the State.  He served for more than 15 years and during that time, was constantly concerned with trying to increase the volume of water that was already scarce in the city of Querétaro, as well as its purity.  The clay pipes that had carried water from the sources were in very poor condition due to the years of service.  A change to   iron pipes would address leaks, improve water quality and quantity, and be a health benefit for the residents of the City of Querétaro.

By 1903 he had begun to construct a new aqueduct which represented a considerable investment.  It was constructed mostly of iron pipe, all the way from the reservoir at old Hercules. Upon completion of the Project, the drinking water distribution system was significantly improved, with twice the volume of water being delivered to the City.

In the 1940s, public health problems and the high incidence of gastrointestinal illnesses necessitated conversion to groundwater sources for water supply.  For the first time, the City began to rely on deep wells to supply drinking water.

The use of groundwater continued through the 1950s and 1960s.  Groundwater represented a reliable source of clean water and proved to be an effective means to remedy endemic diseases that had plagued the residents for so long. Along with continued use of groundwater, the City witnessed the construction of new hydraulic infrastructure as part of the industrialization in accordance with the National Development Plan.

Useful Data and Statistics

Rainwater Collection

The rainwater collection network is the infrastructure that provides for the collection and conveyance of rainwater to discharge points intended for this purpose. This network is composed of rainwater collectors, open drains, (including the Río Querétaro), and wave breaks. Rainwater collectors capture water in a given area, leading to drains to be discharged. The canals are works which capture and regulate water runoff, through a controlled system.

The State Water Commission is responsible, in conjunction with the municipality, for the maintenance of 84 kms. of open drains and the 12 control canals in the metropolitan area of Querétaro.

Sewerage System

The sewerage system consists of a network of pipes and manholes which, according to their function, are divided into sub collectors. They capture wastewater in a given area (housing development, industrial park, etc.) and convey it to collectors, which are networks of higher capacity.  Collectors in turn lead to interceptors which discharge to treatment plants.

The State Water Commission is responsible for the maintenance of these networks with the construction of the same carried out by the Secretaries of Public Works of the State and municipalities.

Treated Water Reuse

Currently we have three sectors for treated water reuse in the Metropolitan area of Querétaro, which are:


To date this year we have an average of 66% treated water reuse in the sectors above, , of which the majority is in agriculture.

Sanitation Infrastructure

The State Water Commission operates 32 treatment plants in the State, which are regulated under Mexican Official Standards that establish maximum contaminant limits in sewage discharges.
