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.

Freshwater is a scarce natural resource due to pollution, droughts, and overpopulation. Catchwater is a sustainable mechanism to increase freshwater in areas facing droughts or polluted waterways.
Lincoln Catchwater Drain doesn’t sound like it should be somewhere to seek out for a couple of hours’ quiet reflection, but bear with me, it really does have a lot to offer.
It is also closely connected to the intriguing story of Lincoln’s water supply. A catchwater drain is a land drain, a ditch cut across the fall of the land, typically just above the level of low-lying, level ground such as The Fens of eastern England, where some land, tens of kilometres catchwater drain experimental catchment book the sea is at about sea purpose is to gather water draining from the higher, sloping ground before it reaches the flat land whence it would be difficult or expensive to remove.

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. River level West Fen Catchwater Drain at Revesby Check for flood warnings in this area.
Latest recorded level m at am Thursday 7 May The size of the drain can be calculated with the formula (17): Q:the capacity of discharge of the drain (in l/s) A:the cross section of the flow (in m 2) R:the hydraulic radius of the drain (see figure F.3, in m) S:the gradient of the drain N:Manning’s roughness coefficient: for earth drains, ; brick drains, Figure AFile Size: 96KB.
Covers passive systems that catch and control storm water as well as active systems that store rain water for later use for drinking or landscape irrigation.
Sufficient detail to support designing and building your own system. Last half of book is "case studies", but nearly all are large commercial systems.
pages, Water From the Sky. A Guide for Rainwater Catchment Systems in the Pacific Tank liners Some people use liners to make a drum or other make-shift tanks more suitable for a catchment. It is important to use only liners of food grade quality, since water usually has longer contact with the File Size: 1MB.
Also, the observed runoff at the outlet of the Catchwater Drain catchment in dry periods, which analyses of channel flow conditions and measurements of discharge showed came from the sandy areas at Great Hatfield, was much higher than the runoff estimated from.

For the vast majority of tank-based rainwater harvesting systems, the catchment area is the roof surface. There are some important factors about the roof to consider when planning for a RWH system.

Water balance components were calculated for the two sub-catchments at Great Hatfield and South Field as well as for the entire Catchwater Drain catchment.
These water balance analyses showed that .Parwan Hydrological Experimental Area The Parwan Experimental Area was established in by the former Soil Conservation Authority.
It is located within the White Elephant Reserve, now owned by the Victorian government. The objectives in establishing the project were to gain a greater understanding of the hydrological processes operating in an eroded catchment, to determine the relationship.
