(RAIN) WATER HARVESTING |
| Total Water Harvesting by Ferrocement Technology |
(Rain) water Harvesting using Ferrocement Technology |
| - Water shall be considered as important as oil |
- Drain Precast 2.4-3.00 Mtrs. long space saving
|
| - There is going to be shortage of water upto 30 to 40% by 2030 |
- Precasting on machinery set up under controlled conditions |
| - Water has to be conserved at any cost. |
- Any cross section |
| - Further let us stop all the river water flowing into the sea |
- Fast construction – More faster with crane |
| - There has to be a crusade to save water |
- Least execution time |
| - Ferrocement is the best technology for the river water harvesting, nalla water harvesting,
rivulet water harvesting, hill water harvesting and rain water harvesting. |
- Perforated precast cover –easily removable for thorough cleaning |
| - The harvesting system shall reduce the temperature around the storage area |
- No manholes |
| - There may be plenty of greenery all around also. |
- Long perforated cover Ferrocement tanks for storage 25-30 mm walls bottom and top Space saving Any capacity |
| |
- Less space occupation |
| |
- With Filtration Boring arrangement |
| |
|
| Ferrocement (Rain) Water Harvesting System |
| - Terrace Rain Water Harvesting is meager |
| |
| - Let us do terrace and land, rain water, nalla water, rivulet water, river water, low lying area water harvesting or any water harvesting |
| |
| - And stop rain water from flowing into the sea |
| |
| - For this our Ferrocement Water harvesting system is most appropriate |

FERROCEMENT, THE BEST MATERIAL FOR (RAIN) WATER HARVESTING
|
Rain water harvesting has become very much significant, in view of the realization that water has become very much scarce and it is going to be very critical problem in due course of time or perhaps very shortly. Rain water harvesting has become the talk of the town in big cities. |
|
In big cities, it is being made compulsory for large size residency to have rain water
harvesting system. For the present, drains are being constructed with conventional materials
such as brick/stone masonry, and R.C.C. side drains are being constructed. Rain water is
made to flow through these drains to centralized water storage tank. From this tank, the
water is expected to be used for the nondomestic and gardening purposes. The water storage
tank is of brick masonry or R.C.C. |
| |
The drains for flow of rain water and the tank for storage of rain water is best constructed
using Ferrocement technology, which is far superior, durable having least maintenance, least
self weight and most tidy. The ferrocement drains are machine made precast products about
2.4 to 5 metres long with covers with perforations of the same length about 25 mm thick.
The surfaces of these drains are very strong and not eroded by flow of water. The bottom
and sides of the water storage tanks consist of ferrocement plates with space frame. These
plates are about 25 mm thick, waterproof, strong, durable and have least maintenance. |

| Ferrocement Drains & Tanks |
Drains & Tanks of conventional material |
| 1) |
The components of ferrocement drains, covers and storage tank are machine made having assured quality. These are brought to site and placed manually or using small crane.
|
The conventional material consists of brick, stones, cement mortar, plaster etc. The R.C.C., if adopted is cumbersome, since shuttering, bar bending, reinforcement placing,concrete and deshuttering etc. is required to be done. |
| |
|
|
| 2) |
There is no phenomena of any plaster application. The manufactured surfaces are smooth, better than plaster surfaces. |
The plaster has to be applied to the drains as well as to the surfaces of water storage tank. This plaster gets eroded after some years and it has to be redone. |
| |
|
|
| 3) |
The ferrocement has unparallel feature of waterproof quality. There are no leakages through ferrocement drains as well as the tanks. The joints are very much leak proof. |
In the case of brick masonry and stone masonry drains and storage tank, leakage problems do come up sometimes very shortly or in due course of time. |
| |
|
|
| 4) |
Ferrocement drains and water storage tank consist of thin ferrocement plates about 25 mm thick. There is very much large quantum of space saving. |
The brick masonry and stone masonry drains and tanks have comparatively very large thicknesses and occupy more space. The walls of R.C.C. are also very large as compared to that of ferrocement. |
| |
|
|
| 5) |
The ferrocement drains and water storage tanks construction saves space to a very large extent. This is most significant in cities where there is a shortage of space. |
No doubt the space occupied by conventional materials is much more. This is most significant in cities, where there is a shortage of space. |
| |
|
|
| 6) |
No manhole cover is required for ferrocement drains. Covers to the ferrocement drains are removable for cleaning. These are 2.5 mtr. long and can be easily handled. |
In the case of brick masonry and stone masonry drains, the covers are of small size, heavy and difficult to handle. Other portion of drain are covered with R.C.C. slab.
|
| |
|
|
| 7) |
Thus the cleaning of drains is most convenient at reasonably low cost. |
The cleaning of drains is cumbersome and costly are not satisfactory. |

 |
Ferrocement rectangular underground water storage tank with Pump House for CIDCO.
Capacity 35000 litres. The tanks can be constructed at terrace level as well as over a tower. |
|
| |
 |
| Ferrocement channels, 2.4 m to 5 mtrs. long with perforated covers of the same length (not shown). The joints are leakproof. The channels are most efficient for roadside drains and irrigation water transportation. |
|
| |
| For urban areas i.e. cities and towns, roadside drains using Ferrocement technology is of great advantage avoiding inconvenience and disturbance to the public as well as traffic movement. |
| 1) |
The work at site shall reduce considerably because precasting of road side drains along with covers shall be carried out in precasting yard. |
| 2) |
As regards R.C.C. road side drains (a) the time taken for construction is quite large (2) the process of excavation, shuttering, reinforcement placing, concreting and final laying of cover slabs is quite cumbersome, disturbing and inconvenient to the BMC organisation as well as the public. The quality control is many times in doubt.
|
| 3) |
The task of cleaning the drains is very much difficult, arduous and perhaps the drain might get filled up to almost full after a lapse of some years. The reasons being the cleaning staff has to enter through manhole in a space of about 10 ft. spacing and clean. In the case of Ferrocement drains, covers of length of 2.4 mtrs. to 3 mtrs. can be made to handled manually or by a very light crane. These covers can be removed, set aside and whole drain is open for cleaning. This cleaning can be conveniently done by means bucket excavation. The system shall be very much efficient, subject to easy supervision and check and may be economical. |
