Aqueducts and Sewage Systems. Rainwater Recycling: Case Study of a Health Facility

Aqueducts and sewage systems. Rainwater recycling: case study of a health facility

Abstract
The author of the essay intends to prove that water must be considered in the future as a primary resource available to all and not – as the present trend indicates - as a privately managed commodity.

The distribution of this essential resource are examined, its scarcity in several areas of the Planet discussed and proposals to mitigate the deriving problems are offered.

The study starts with a detailed analysis of the bad habits adopted by the so-called civilized community in the use of water, and ends with a series of useful rules of behaviour and technical systems to recycle and conserve it.

Emphasis is put on rainwater collection and harvesting policies and methods, which the author adopts as one of the answers to this ever-growing problem. The issue is supported by detailed hydrological records, schemes and calculations.

The core section of the research is in fact based upon the description of a rainwater harvesting system to be implemented on a health facility located in Southern Italy.

The system is thoroughly described and its costs/benefits analyzed in full detail.
