Properly serving the interests of the municipalities’ citizens should be a priority for municipal companies, providing a response to society’s needs based on a culture of working together and of co-ordination at the operative and functional levels. In our case, our priority are the municipal areas on the Western Costa del Sol that we supply.

What are the concepts included on the receipt?

Imagen explicación factura Acosol

Fixed or Service Charge: This is the fixed amount that users must pay on a regular basis for availability of the service, regardless of whether or not it is used.

Variable or Usage Charge: This is the amount that the user pays on a regular basis based on the amount of water used. To calculate this fee, the increasing block rate is used. Water usage is broken down into pre-established limited blocks, with prices that increase with each block. The number of blocks used cannot exceed four in domestic use.

Special charges: Independently to the rates established previously, in providing the water service to a population, a sector of it, or certain specific subscribers, for reasons relating to the use of installations that differ from those used in normal supply situations, such as at a particular elevation or for desalination, these generate an additional cost to that of general usage. The supply company may apply an extra charge per cubic metre billed for affected subscribers to cover most of the cost resulting from the different type of treatment required, and may do so on either a permanent or a temporary basis.

Fees: A fee is a charge applied independently to the rate to meet the cost of infrastructure investments. This payment is used solely for this service.

All the above will also apply to billing for comprehensive sanitation, both in billing per blocks and in the fee.

How are meter readings taken?

On a regular basis by staff from our company. In the event of it not being possible to take a meter reading, the subscriber can inform the company of the reading by email or telephone, or by visiting any of our offices.

Can the company shut off my water for non-payment?

Yes. Using the procedure established for this purpose in the Home Water Supply Regulations approved by the Regional Government of Andalusia.

What rights do subscribers have?

  • Right to water that is safe to drink.
  • To the provision of a permanent service.
  • To the services received being billed for the concepts and amounts that are in effect at any given time.
  • To regular readings and bills.
  • To a contract being drawn up in writing.
  • To be free to choose the authorised installer of your choice to carry out interior installation.
  • To lodge complains and receive information on all queries.
