The cost of the locally fabricated CRT with a minimum capacity of 600 liters ranges from PhP 3,500-5,000 (mat and frame not yet included). According to a hardware, the price of a stainless steel tank with a capacity of 800-1,000 liters is between PhP 15,000- 19,000, while the price of a polyethylene tank with a capacity of 600 liters is at least PhP 8,200. The fabrication cost of CRT is cheaper compared to the cost of rigid tanks. However, proper comparison in terms of life span and durability cannot be concluded yet, as the locally fabricated CRT is still under test and research. However, it can be noted that rigid tanks can be used from 8 to 14 years and based on the experiences of long-time users abroad, CRTs have a warranty of approximately 5 years (Portable Tanks, 2014). It is important to consider certain factors that affect the lifespan of a tank, mainly: fabrication materials, application, environment, and external influences such as temperature and exposure to heat. The recommended average water use in the Philippines is 120 liters/capita/day (Philippines Environment Monitor, 2003). Assuming that the average number of household members is five, the monthly consumption of a household is 18,000 liters or 18 m3 on the average. The cost of the first 10 m3 is PhP 183 and PhP 19.20/ m3 for the succeeding 10 m3. The water consumption cost is PhP 336.60 (2% tax included). With this current water rate in Calamba City, monetary savings from using the collapsible tank is minimal.

The RWH system is relatively simple to use and potential users can easily be trained on how to install the tanks. In determining the size of the CRT, information on average annual rainfall, roof catchment size, installation area, and water demand were necessary. Aside from the CRT, the house should have a gutter and spout. There should be some space to install the CRT. The developers of the CRT still need to improve the tank design, durability, use of locally available materials, filtration system, water quality assessment, and application in agriculture, emergency and relief operations.

This technology was pilot tested in 12 households. When asked whether they would still use the CRT if available commercially, the co-operators gave a generally favorable and positive response. Since the CRT is covered, entry of dengue-carrier mosquitoes was prevented and breeding in the tanks was reduced, if not stopped. As a result, the project was endorsed by the barangay officials and the pilot-testing of the CRT in the area was readily welcomed by the residents as an alternative to their usual water containers.

It lessens water run-off and reduces the amount of groundwater being extracted.
