What are the benefits of building renewable utilities that integrate energy (thermal and electric) and water?

Water and Energy:

Benefit:

Water reclamation can anchor the creation of a district energy system.  The creation of district energy system can enable the distribution and reuse of reclaimed water into a community.

How it Works

  • Construct a water reclamation plant to recover the energy and water from sewage

  • Subscribers to the wastewater treatment plant provide the initial cash flow and enable the initial utility.

  • When expanding the utility, it is the higher value resource that will subsidize the ongoing expansion of the utility.

  • If the revenue per household from sewage treatment is $300 and the revenue per household from heating/cooling is $1,500; one home connected to the district energy system provides 5 times the revenue from connecting a home to the sewer. Revenue from reclaimed water helps to cover the operating costs.

  • One of the key enablers of reusing the water throughout the community, is that the reclaimed water is both a source of non-potable water and the carrier of thermal energy. The latter is a much higher value resource.

  • This makes the TITUS DESS system an essential driver for reducing greenhouse gas emissions and reusing water and energy across the community.

  • More importantly, by combining services, customers should see a 10% savings on their utility bills.

Thermal and Electrical Energy

Benefit

By reducing a community energy supply requirements by 50% with a TITUS DESS you can double the feasibility of other renewable electricity systems (wind, solar pv, biomass, waste to energy, etc.)

How it Works 

  • Typically 55% to 65% of a community's energy consumption is related to heating, cooling and domestic hot water.

  • By providing 90% of the thermal energy by alternative means, you actually reduce over 50% of a community's energy supply requirements.

  • By reducing 50% of a community's energy supply in this way, you can often double the feasibility of the renewable electricity systems (wind, solar pv, biomass, waste to energy, etc.)

  • If you have a renewable electricity source that provides 7% of your needs, that source will now provide 14% of your needs.

Potable and Non-Potable Water Supply

Benefit

By reducing the potable water supply of a community by 40% we increase the capacity of the reservoir and reduce the treatment and pumping costs of the water utility.

How it Works

  • By providing reclaimed water back into the community for irrigation, toilet flushing, laundry and other non-potable applications, we reduce the demand on the on the reservoir by 40% per year, 

  • That is 40% of the water that does not need to be treated to drinking water quality,

  • This is 40% of the water that does not need to be pumped from the reservoir,

  • This has a compounding effect on the capacity of the reservoir.
