JECO-WSS
JECO-WSS [Water Supply System] for buildings under construction
The construction industry requires very rugged solutions for their demanding site conditions. Water and power are big inputs, besides aggregates, cement, steel, etc. But wastage of power and water is rampant. The JECO- WSS saves in capital cost and also running costs on a day to day basis to the user. It helps in controlling of operations, improving concrete quality, work speed, etc.
Depending on the construction speed, clients recover the entire system cost from the savings in water and energy in a few months. It should qualify as a “GREEN” system in the contracting/construction industry.
The system comprises a battery of high efficiency pumps of compatible specifications installed in parallel. These will deliver to a special header, connected to an instrument line. The water line from the header extends up to the top and to the farthest delivery points. Pumps are controlled by a PLC based panel with scores of user friendly and pump & system safety features.
WORKING OF THE SYSTEM
When the pumps are running, delivery pipe is under pressure. An estimated amount of water & air gets stored in the system. In a contemporary system one needs pressure tanks which must be charged frequently by a dedicated air compressor or one uses pressurized diaphragm tanks, which must be periodically recharged and checked. Besides requiring more attention, a good deal of energy is lost to air replenishment needs. “JECO-WSS” does not need an air compressor or diaphragm tanks.
This is just one of the advantages of the system.
Storage volumetric efficiency is extremely high. In “JECO-WSS”, the stored energy of water (and compressed air) is fully utilized, ensuring extremely high system operating efficiency & lower power consumption. Frequency of pump starts and stops is at times as low as 1/10th of a contemporary HPN system. Pumps also run fewer hours as compared to any other system. Thus are more rested.
System configuration ensures cyclical operation of pumps which also duty assist, pumps get equally utilized.
“JECO-WSS” compares very favorably against a VFD based or other [DOL/Star Delta] HPN systems. Manual systems result in even higher loss in energy and water.
COMPARISON BETWEEN CONVENTIONAL SYSTEM AND JECO-WSS
| CONVENTIONAL SYSTEM | JECO-WSS |
| Total installed Hp is much higher. Typically, the P&M persons in consultation with the civil engineers decide the maximum water flow required during the construction activity. The Pump size installed is based on this requirement. | Total installed Hp is lower. A series of pumps are installed in parallel to take care of maximum and minimum flow requirement. When load [water demand] is high, more pumps start and supply together to satisfy the demand, so that construction speed and quality does not suffer. |
| When water requirement is less or even nill, pump still
throws high quantity of water at full power. Excess
water, which is a very substantial quantity is wasted
[or may return back to the storage tank/sump], but
power is definitely wasted.
Plumbing related leakages is an additional problem. |
When water requirement is less, pump[s] throws lesser
quantity of water. Few [or only one] pump operates.
Very often no pump operates but the demand is met by
the water stored in the system. Loss in energy or water
on account of the system is zero.
System also assists in removing plumbing related leakages and losses. |
| A standby pump of equal capacity is required. | System has an in built arrangement of a standby pump. |
| No control or indication as to whether water and power is being actually used or simply wasted [or returned to the storage tank or sump]. | Better Control on operation: Power and water used can be linked to work load. Thus based on the pump operation, which is automatic, one can gauge the speed of work being carried out. |
| Manually switch the pumps ON and OFF.
When work load [Water Demand] is high, manually switch ON more pumps. Work will suffer because of the time lag. |
Fully automatic operation, system is always alive. When water demand is high, even for a short period of say one minute, more pumps will automatically come ON. Work will not suffer. |
| Pumps are not equally utilized. No of working hours is more. Maintenance and spares cost is higher. | Pumps are equally utilized, So longer life. Much fewer working hours. Lower maintenance and spares cost. |
| Water is used to cure concrete. The manual system
does not have any pressure maintenance mechanism,
it is an open loop system. It is physically not possible to
reach the upper portions of the slabs, columns, walls
standing on the floor, so water may not reach their.
Quality of curing and concrete is a suspect. |
System is optimally pressurized, ALWAYS. So
irrespective of the vertical height of the column, walls
and slabs, water spray will reach the farthest point and
concrete will get properly cured.
Good quality of curing and concrete is ensured. |
| Ample down time and work hours lost. | Practically zero downtime. |
| Requires more space, a proper pump room, etc. | Silent operation and requires very little space. |
| If site is closed for a few days, pumps may jam and require servicing. | Automatic checking and running of the pumps is inbuilt. |
| Lead time to satisfy sudden spurts in demand is longer. | Satisfies sporadic and sudden spurts in demand almost instantaneously. Lower friction loss. |
