By , the water catchment area has increased from half to two-thirds of Singapore’s land surface with the completion of the Marina, Punggol and Serangoon reservoirs. As part of its comprehensive and rigorous water quality monitoring programme, PUB actively tracks and safeguards the raw water quality in its reservoirs through sampling and. Catchman definition is - one who sorts floating logs according to owner's mark by deflecting them with a pike pole.

For water, a catchment is simply defined as an area of land around a river, lake or other body of water. Living in a catchment that has healthy water can help a community to have a better quality of life. A healthy water catchment provides high-quality drinking water and supports livelihoods such as agriculture, recreational angling and water. Rain Catchment. Rainwater harvesting is a economical alternative in the right climates. Also called rain harvesting, these simple systems connect downspouts (gutters) to a central water tank capable of holding about , litres of water or more. Often, in African countries, the issue is not that it never rains, but rather that when it does.

With an area of about km 2 and growing urban areas, Singapore lacks the space to collect and store all the rain that falls on it. Through a network of rivers, canals and drains, rain that falls on two-thirds of Singapore's land area is channelled to our 17 reservoirs. Singapore has two separate systems to collect rainwater and used water. Passive rainwater harvesting systems use land shaping and other techniques to direct, collect, and infiltrate rainwater into the soil for beneficial use. A typical passive system consists of a catchment surface, infiltration area and overflow structure. Examples of passive rainwater harvesting systems include rain gardens, bio retention swales.

The Little Thetford catch-water drain was constructed in John Parish of Bedwell Hey Farm tells us his great-grandfather was the surveyor.

The catch-water drain was completed six years before the Little Thetford Act of enclosure. The purpose of the catch-water drain is to stop water running off the high ground of the parish into the surrounding low-lands where it is more difficult.
