Read the following passage carefully and answer the question:
In recent municipal governance initiatives across several semi-arid districts, local urban bodies launched a decentralized rainwater harvesting incentive scheme to tackle acute urban water scarcity. Under this policy, residential welfare associations that install certified rooftop rainwater collection and filtration systems receive a fifteen percent rebate on their annual property taxes. Additionally, the municipal administration provides free annual technical audits and structural maintenance guidelines for the first two years following installation. The primary policy goal is to reduce municipal expenditure on tanker-based emergency water distribution during peak summer months and to replenish depleting local sub-surface aquifers.
Initial monitoring across thirty urban sectors revealed a twenty-five percent decline in municipal tanker deployments within eighteen months of implementation. However, municipal evaluation reports highlighted that system maintenance compliance dropped sharply in residential sectors where underlying groundwater was naturally brackish. In these areas, residents reported that harvested rainwater stored in underground sumps frequently mixed with saline seepage, rendering it unsuitable for non-potable household usage without secondary treatment. Consequently, municipal policy advisors have emphasized that standardized property tax rebates alone are insufficient to guarantee long-term operational sustainability across diverse topographies unless accompanied by site-specific technical interventions, localized water quality testing, and targeted subsidies for secondary filtration units.
Based on the logical implications of the passage, which administrative action would be most effective in restoring maintenance compliance in areas affected by brackish groundwater?
- Complement property tax rebates with targeted subsidies for secondary filtration units and site-specific water quality testing in affected sectors.Answer
- BIncrease the property tax rebate from fifteen percent to thirty percent for all residential sectors across the entire municipality.
- CImpose immediate financial penalties and revoke tax rebates for welfare associations in brackish areas that fail to maintain their collection sumps.
- DDivert all municipal rainwater harvesting funds toward constructing centralized industrial desalination plants across the district.
