Project 3: Waterboard Groot Salland – Sustainable swimming pool

Planning Realisation Monitoring Evaluation
Waterboard Groot Salland – Sustainable swimming pool

The temperature of the effluent of the wastewater treatment plant varies from 8 to 20 C º and thus contains thermal energy. Effluent is discharged into surface water. This is not an ideal situation, because the thermal energy has a negative effect on surface water. Furthermore, a potential source of energy is lost. In this project the water board Groot Salland and the municipality of Raalte want to use thermal energy from the effluent to heat the nearby swimming pool Tijenraan.

An indicative calculation shows that the thermal energy from the effluent can considerably reduce the demand of conventional energy of the swimming pool.

The questions to be answered in this project are:

  • What is the most efficient way to use the thermal energy from effluent to heat a public building?
  • How can we overcome the organizational, financial and legal barriers we encounter?

Results

  1. Insight in the variety of energy supply and demand during the year.
  2. The development of the most efficient thermal energy transfer system (TETS).
  3. A better understanding of the organizational, financial and legal consequences of the energy transfer system and the realization (including cost recovery time).
  4. The construction and startup of TETS.

Planning

23rd of June 2011 until the end of 2013.
