Local Laws Overview

Key themes and local legal features that are particularly relevant in Sintra include:

- Public ownership and public interest - Water resources are managed as a public interest. Private use normally requires authorization, and the state or delegated authorities oversee sustainable use.

- Permits and licences - Abstraction of groundwater, drilling wells, wastewater discharge and some construction works near watercourses typically need administrative permits or filings. Different permits may be required from municipal services, regional water administrations and national agencies.

- Integrated basin management - Water management is organized around river basins and catchment areas. Planning documents at basin level guide allocation, protection measures and long-term management strategies that apply to Sintra.

- Water supply and sanitation - Municipalities usually ensure drinking water supply and sewerage services, often through municipal utilities or concessionaires. Service contracts set operational, billing and quality rules and can be subject to administrative review.

- Environmental protection and pollution control - There are strict controls on discharges, waste disposal and activities that risk contaminating surface water or groundwater. Authorities can order remediation and apply fines in case of non-compliance.

- Flood risk and land-use planning - Local land-use plans and national flood risk rules may impose setbacks, building restrictions or mandatory mitigation measures when works are proposed near rivers, streams and coastal areas.

- Fees and tariffs - Charges can apply for water use, abstraction, wastewater treatment and permits. Tariff setting is regulated and may involve national or regional regulators as well as municipal bodies.

Frequently Asked Questions

Who owns water in Portugal and can I use a stream on my land?

Water is treated as a public resource and the state has the primary responsibility for its management. Landowners may have certain local rights - for example, access to a stream that crosses their land - but these rights are subject to regulation, environmental protections and any required permits. Private use that affects the public interest or the resource itself may require prior authorization.

Do I need a permit to drill a well on my property in Sintra?

Yes - drilling a well or abstracting groundwater generally requires authorization from the competent authorities. Authorities assess resource sustainability, potential impacts on neighbours and public supply, and environmental protection. Always check with the municipal services and the regional water administration before drilling.

How do I get a connection to the public water supply or sanitation system?

Contact the municipal services responsible for water and sanitation in Sintra. You will normally need to submit a formal request and provide documentation about the property and works. The utility or concessionaire will outline technical requirements, connection fees and the timetable for connection. A lawyer can help review any contract terms or challenge unreasonable conditions.

What should I do if my drinking water is contaminated?

Immediately report the issue to your water supplier and to the municipal or regional environment authority. Preserve samples if it is safe to do so, keep records of all communications and, where appropriate, seek medical advice. A lawyer can advise on liability, administrative complaints and compensation claims if contamination resulted from negligence or unlawful activity.

Can a neighbour be stopped from taking water that affects my supply?

Yes, if the neighbour’s abstraction unlawfully affects your rights or the public resource. Remedies can include administrative complaints to the authorities, requests for enforcement, and civil actions for nuisance or damages. Evidence of the impact and technical expert reports will often be necessary.

What are the consequences of discharging wastewater without a permit?

Unauthorized discharges can lead to enforcement actions, fines and orders to remediate contamination. Serious or persistent violations may trigger criminal liability in addition to administrative penalties. Acting promptly to regularize the situation and cooperating with authorities can reduce legal exposure.

Are there restrictions on building near rivers, streams or the coast in Sintra?

Yes - land-use plans, flood risk rules and environmental protections impose restrictions and set technical conditions for construction near water bodies. Prior authorization may be required, and environmental impact assessments can be necessary for larger projects. Check municipal planning rules and consult professionals early in project design.

How are water tariffs and fees determined?

Tariffs for water supply, sewerage and related services are set under a regulated process that involves the service provider, municipal authorities and national regulators. Fees for permits and resource use are generally established by law or regulation. If you believe charges are unfair or incorrect, administrative review and judicial appeal routes are available.

What happens during declared droughts or water scarcity measures?

Authorities may adopt restrictions or emergency measures that limit certain uses - for example, irrigation, filling pools or industrial uses - to prioritize drinking water and essential services. Non-compliance with restrictions can result in fines. Legal advice can help interpret measures and protect essential rights where appropriate.

How do I find the specific rules that apply to my property or project in Sintra?

Begin by checking municipal planning instruments and permits, and consult the regional water administration and the national environment agency for basin management rules. If your matter involves licenses, environmental impact or enforcement, seek a lawyer who can obtain relevant administrative records, interpret applicable law and represent you in proceedings.
