How your Best Practice is economically feasible ?
The financial feasibility of the system is based on the principle of treating and reusing wastewater generated from public transportation vehicles washing operations. By reusing the recovered water in washing operations, municipal water consumption is significantly reduced. This not only saves the money on water supply costs but also reduces wastewater discharge costs. Thanks to the high water recovery rate, the system recoups its investment and operating costs within a certain period, creating an economically sustainable structure.Result of this assessment
The system was established in 2017. Since its installation, it has been used daily for washing buses. Periodic maintenance is carried out by municipal staff. It is a sustainable and trouble-free system.Enviromental impact

Validation/upscaling
Similar applications have been implemented and are operational in other municipal bus washing garages in İnciraltı, Çiğli, and Torbalı.
Potentiel of exploitation/outscaling
Yes, there is potential and it is being implemented. Steps have been taken to establish similar systems in Urla and Adatepe bus washing garages.
Lessons learnt
The simple design of the system has ensured its sustainability. Regular maintenance and filter replacement are required, the operational status of the system must be monitored, chemicals should be…
Recommandations
Installation of similar systems integrated with rainwater and greywater is ongoing in other municipal bus garages. It is possible to further improve the system by supporting it with new technologies.
