Water intake design and DGA water rights consulting in Chile
Intake design, DGA filings and environmental permits PAS 155, 156 and 157.
What we do
We design surface and groundwater intakes.
We prepare the technical files required by the DGA and the SEA: approval of hydraulic works (PAS 155), river channel modification (PAS 156) and channel regularisation and protection (PAS 157).
We respond to DGA, DOH and SEA comments and provide hydraulic support for environmental impact declarations and studies.
We deliver the hydraulic component of sectoral permits together with environmental consultancies, in particular PAS Consultora, with whom we have prepared several permit files.
When you need it
- When the project abstracts water from a river or stream.
- When it alters a channel or builds river protection.
- When the environmental assessment requires a hydraulic sectoral permit.
Software and standards
HEC-RAS, HEC-HMS and QGIS. Chilean Water Code, SEIA regulations and DGA guidelines.
Typical deliverables
- Technical permit report
- Hydrology study
- Hydraulic modelling with and without the project
- Drawings of the works
- Responses to authority comments
What we need from you
Water rights or pending application, intake location, design flow, channel survey and status of the environmental assessment.
Frequently asked questions
What is the difference between PAS 155, 156 and 157?
PAS 155 approves hydraulic works such as intakes or small dams, PAS 156 authorises channel modifications, and PAS 157 covers channel regularisation and protection. Many hatchery assessments need more than one.
Can you answer comments on a file already submitted?
Yes, even if we did not prepare the original file.
