1 M31.2 Opa Water Supply Scheme M Observations for Water Treatment Plant The Opa facility has been augmented over the years and currently consists of 4 river intakes (one for each self contained WTP). The original site contains Plant I, 8 commissioned in 1957 and Plant II, 12 commissioned in Plant III, 52 commissioned in 1972 (later increased to 72 by adding an extra filter bed) and Plant IV, 4 commissioned in 24 are both sited at Curti, approximately 2. km away. Table M lists the summary of asset data for the WTP and Table M contains detailed asset data for the WTP. The plant schematic is shown on Figure M Both compounds, Opa and Curti, are adequately gated, fenced and secured by 24 hour on-site security personnel. All plants are operated and maintained 24 hours a day, using a three shift system. Except for the newest plant, flow measurement devices are not installed. Therefore, the amount of raw water supplied to the plants and the clean water fed to reservoirs was estimated based on pump design capacities and hours of operation. The original compound has a process control laboratory for the 8 and 12 plants. These plants are manually controlled. Considering the respective ages of the plants, most of the equipment appears to be in good working order, except for the alum and lime mixers. These mixers appear to be in poor order or out of service. Both plants have good maintenance standards. Disinfection is achieved using gas chlorination. The chlorination is delivered using one tonne cylinders. Maintenance, installation standards and operation practices for chlorine use are poor. There are no facilities for adequately detecting or containing gas leaks. Personal breathing apparatus is available in the laboratory but is not used or maintained. Records of chemical usage and treatment parameters are logged by the laboratory staff. Records of pump running hours, load, filter backwashing and clear water reservoir levels are logged. However records of repairs and maintenance/breakdown problems are not logged. The high speed pump couplings/shafts are not guarded. M31-47

2 The 4 plant has its own process control laboratory. Records of the chemical usage and treatment parameters are logged by the laboratory staff. M/S Environ Control Associates Private Ltd Surat built, operated and maintained the plant for 18 months before handing it over to the PHE. A basic operation and maintenance manual was provided to the PHE at this time outlining basic operating, maintenance and H&S instructions. On the job training was provided by the contractors during the operation and maintenance period. The plant appears to be in good working order and maintenance standards are good. The plant is manually operated but electrical valve actuators are in use. It is understood that a proposal to install a SCADA system has been prepared. Records of pump running hours, load, filter backwashing and clear water reservoir levels are logged. However records of maintenance, repairs and maintenance/breakdown problems are not maintained. Disinfection is achieved using gas chlorination. The chlorination is delivered using three, one tonne cylinders. Maintenance, installation standards and operation practices for chlorine use are poor. There are no facilities to adequately detect or contain gas leaks. Personal breathing apparatus is available in the laboratory but is not used or maintained. The 52 plant has its own process control laboratory. Records are logged by the laboratory staff for chemical usage and treatment parameters. Records are kept for pump running hours, load, filter backwashing and clear water reservoir levels. However records of maintenance, repairs and breakdown problems are not maintained. An Electro-chlorination system is used for disinfection. This appears to be in good working order and maintenance standards are generally good (except for the chlorination room). Gas chlorination using one tonne cylinders is available for back-up purposes but appears to be in relatively poor condition. There are no facilities to detect or contain leaks. Tables M and M and Figure M show the flow rate data for Opa/Curti Treatment Plants. Table M and Figure M show the data on monthly water quality at Curti Water Treatment Plant. Table M shows records on power outages at Opa Water Treatment Plant. M31-48

34 M31.3 Chandel Water Supply Scheme The Chandel facility consists of a 15 plant commissioned in 22. Raw water is sourced from the Kalana River which is pumped approximately 15m to the plant. The site contains a clear water sump from which water is pumped to the MBR approximately 8m away for onward gravity feed to the distribution system. We understand that prior to commissioning of the plant, a number of rural water supply schemes were in operation and the networks for these schemes are now interconnected with the Chandel plant. We understand that the rural schemes serve to augment the regional scheme at peak demand times. Table M lists the summary of asset data for the WTP and Table M contains detailed asset data for the WTP. The plant schematic is shown on Figure M The raw water pump house and treatment plant are located in separate compounds. The study team found these compounds to be adequately gated, fenced and secured by 24 hour on-site security personnel. The plant is manually operated. The plant operates 24 hours a day, and using a three shift system. The distribution network currently needs to be enhanced, therefore the plant operates at only 8.5. Raw water supplied to the plant is measured at the par shall flume. This flume has a working flow measuring device. Flow measurement devices are not installed at the MBR or beyond. Therefore, transmission via the clean water reservoirs is estimated based on pump design capacities and hours of operation. The raw water pump house has four pumps (two duty) each with a capacity of 2 l/s. Maintenance standards are good and the drive couplings/shafts are well guarded. Maintenance is generally reactive, except for regular oiling and greasing. There is no operation and maintenance manual (although some equipment catalogues are available) and training for new staff is only provided on the job by existing experienced staff. There are no written or formal safety systems for plant operation. The treatment plant is controlled manually. Most equipment appears to be in good working order, except for the alum and lime mixers. The lime mixers were not functioning at the time of the site visit, which meant lime was added by hand at the flash mixer point. Generally, good maintenance standards are evident and the water pumps are well guarding. Currently there are no logs maintained at the plant. M31-8

35 The plant does not have an on-site laboratory, although equipment for measuring residual chlorine and ph levels is available. Residual chlorine and ph are measured hourly by the plant operators to inform the process control, however records of the measurements are not kept. Staff from the Panaji laboratory visit the site and take samples for analysis once a week. Gas chlorination is used to disinfect the water. Chlorination is achieved using one tonne cylinders. Normally there is one cylinder in the chlorine house at any one time. There is only one vacuum type chlorinator, meaning there are no standby chlorinators. The study team was advised that another chlorinator will be installed. Maintenance of the chlorinator is undertaken in-house, but periodic calibration is not undertaken and no maintenance records are kept. No spare parts for the chlorine facility are kept on-site. Maintenance, installation standards and operation practices for chlorination are poor. Ammonia solution is used to detect leaks from the pipes and the connection joints. The only facility to detect or contain gas leaks is an immersion tank, however it is not easily accessible during an emergency. The feeder pipe to the contact tanks is made of poor quality flexible plastic hose and it is unprotected. This is not safe and should be rectified immediately. Personal breathing apparatus is not provided and staff are not aware of the safety procedures / measures required during the chlorination process. Table M and Figures M show the data on monthly water quality at Chandel Water Treatment Plant. Table M shows a list of existing reservoirs for Chandel Water Supply Scheme. M31-81

48 M31.4 Assonora Water Supply Scheme The Assonora facility consists of a 12 plant commissioned in 1968 and a 3 planned commissioned in The 12 plant sources water from the Amthane Dam by gravity feed approximately 1 km from the plant as well as a supplementary supply from the Assonora River via a jack well. The river source supply line is interconnected with the 3 plant to supplement the main incoming raw water supply from Podocem (2 km s away) which provides 25 to the plant. The site also contains a clear water sump for the approximately 15 treated water received from Podocem WTP for onward distribution to the Assonora supply area. We understand that a proposal for an additional 4 plant has been prepared and submitted to PWD for approval. Table M lists the summary of asset data for the WTP and Table M contains detailed asset data for the WTP. The plant schematic is shown on Figure M The raw water pump house and the treatment plant are located within the same compound. The compound is adequately gated, fenced and secured by 24 hour on-site security personnel. The plant is manually operated and operates for 24 hours a day, using a three shift system. Flow measurement devices are not installed. Therefore, raw water supplied to the plant (from the dam, river and Podocem), clean water fed to the plant from the Podocem WTP, and onward transmission via the clean water reservoir was estimated using pump design capacities and pump operating hours. The raw water pump house has three pumps (one duty) each of 15 capacity. Maintenance standards are good, however the drive couplings/shafts are not adequately guarded. Records of pumping hours, loads etc are logged, however maintenance records are not kept. Maintenance is generally reactive to rectify problems as they become apparent, except for oiling and greasing which is undertaken regularly. There are no operation and maintenance manuals available and training for new staff is only provided on the job by existing experienced staff. There are no written or formal safety systems. The treatment plants are manually controlled. Most equipment appears to be in good working M31-94

49 order (considering the age of the plant) except for the alum and lime mixers which do not work. Since the alum and lime mixers are out of service lime and alum are added by hand at the flash mixer point. Generally, good maintenance was evident and the treated water pumps were well guarding. This plant should be used as an example of good practice for the other sites. Records of pump running hours, load, filter backwashing, and clear water reservoir levels are logged. However repairs to assets, maintenance and responses to breakdown problems are not recorded. The laboratory staff keep records of chemical usage and treatment parameters. Disinfection is achieved using gas chlorination. Chlorination is achieved using one tonne cylinders. There are usually eight cylinders in the chlorine house at any one time (five are empty). There are four vacuum type chlorinators (two are for standby). Maintenance of the chlorinators is performed in-house, however periodic calibration of the chlorinators does not occur and records of maintenance are not kept. Maintenance, installation standards and operation practices for chlorine use are poor. Ammonia solution is used as a means of detecting leaks along pipes and at the connection joints. Immersion tanks are the only facilities available to detect or contain gas leaks, however they are not easily accessible during an emergency and were empty when the study team visited the site. During the site visit, flexible copper pipes were noted to be trailing on the platform, presenting a trip hazard and placing the pipes in danger of being damaged. This is not a safe practice. The feeder pipe to the contact tanks is PVC and unprotected, which is not a safe practice. Personal breathing apparatus is available in the laboratory but is not used or maintained. This facility is probably in the poorest condition of all the facilities visited and presents a serious health hazard. The clean water reservoirs are cleaned every six months by PHE staff. There are no safety precautions, safety equipment, or safety systems implemented during the work. The cleaning procedure consists of removing the covers to provide fresh air to the workers and to allow the workers to enter. The desludging is undertaken manually by hosing/flushing down the internal surfaces. Tables M and M and Figures M and M show the data on monthly water quality at Chandel Water Treatment Plant. Table M shows a list of existing reservoirs for Assonora Water Supply Scheme. M31-95

72 M31.5 Sanquelim Water Supply Scheme Table M lists the summary of asset data for the WTP and Table M contains detailed asset data for the WTP. The plant schematic is shown on Figure M Tables M and M and Figures M and M show the data on monthly water quality at Chandel Water Treatment Plant. Table M shows a list of existing reservoirs for Sanquelim Water Supply Scheme. Podocem WTP The Podocem WTP was built recently (23) and has a design capacity of 4. The newly constructed raw water pump house supplies the plant with water from the Valvant River. The water is pumped approximately.6 km from the river. There are three pumps (two duty). These pumps are not adequately guarded. A record of running hours, loads etc. is logged. The operation and maintenance of the pump house and treatment plant has been contracted to a local company (run by a retired PHE engineer) on a three monthly basis. This may be revised to be a longer contract (2-5 years). The pump house compound also contains a pump house that was commissioned in It contains two pumps (one duty). These pumps are not adequately guarded. This pump house supplys 25 to the Assonora WTP via a short rising main to a reservoir. The water is fed by gravity from the reservoir to the Assonora WTP which is located approximately 2 km away. A log of running hours, loads etc. is maintained. A third pump house, which contains two pumps (one duty) was commissioned in This pump house supplies water to the 12 Sanquelim WTP via a.6 km rising main. This pump house is untidy and the pumps are not adequately guarded. A log of running hours, loads etc. is maintained. Both the raw water pumping compound and the treatment plant compound are adequately gated, fenced and secured by 24 hour on-site security personnel. The plant is in operation 24 hours a day using a three shift system. Flow measurement devices are not provided on-site. Therefore, the amount of raw water supplied to the plant, as well as the amount of clean water fed to the transmission system via the clean water reservoirs, is estimated based on pump design capacities and hours of operation. Logs are maintained for pump running hours, loads etc, however maintenance records are not M31-118

73 kept. There is a well established system of monthly oiling and greasing. However, other maintenance is reactive. No operation and maintenance manuals are available. Training for new staff is only provided on the job by existing experienced staff. There are no written or formal safety systems for plant operation. The treatment plant is manually controlled but the valves are operated remotely by pneumatic actuators. The plant is new and appears to be in good working order, including the alum and lime mixers. Generally, the maintenance standards are good, however the pump couplings/shafts are not adequately guarded. Logs are kept for pump running hours, load, filter backwashing, and clear water reservoir levels. However, there are no maintenance logs recording repairs to assets or maintenance/breakdown problems. Logs are kept by the laboratory staff for chemical usage and treatment parameters. Disinfection is achieved using gas chlorination. The chlorination uses one tonne cylinders. There are usually two cylinders in the chlorine house at any one time. There are two vacuum type chlorinators (Metito Mach4). Maintenance of the chlorinators is performed in-house, however the chlorinators are not periodically calibrated and records of maintenance are not kept. Operation and maintenance practices for chlorine use are poor. Ammonia solution is used to detect leaks from the pipe and from the connection joints. There are no facilities to adequately detect or contain gas leaks, in particular, no immersion tank is available. Personal breathing apparatus is available in the laboratory but is not used or maintained. The copper connection pipes are repaired locally and appear to be in poor condition. These existing pipes should be discarded and not repaired. The galvanised iron feed pipe to the contact tank is badly corroded and should be replaced. The clean water reservoirs are cleaned annually. During cleaning, the covers are removed to aid natural ventilation and to allow the workers to enter. The workers undertake the sludge removal and flushing. There are no safety precautions, safety equipment or safety systems. Sanquelim WTP The WTP consists of a 7 plant and a 5 plant. Both of these plants were commissioned around The plants are manually operated. Despite their age, the plants appear to be in good working condition. Maintenance standards appear to be reasonable across the site, except for the chemical mixing areas. The chlorine house is equipped with a one tonne cylinder and one vacuum type chlorinator. There are no standbys. Logs are maintained for pump run hours, load, chemical use and treatment parameters. M31-119

95 M31.6 Dabose Water Supply Scheme The scheme consists of a 5 plant, commissioned around We are told that the plant is currently running at 7 to help met demand. The raw water pump house contains two pumps (one duty) and takes water from the Madei River. The pumps are well guarded. The plant is manually operated. The plant appears to be in good working condition despite its age. There are no flow measuring devices. Security arrangements at the site are good. Maintenance standards are very good, except for at the chemical mixing areas. The chlorine house is equipped with two No. 1 tonne cylinders and one vacuum type chlorinator. There is no standby chlorinator. An immersion tank is available. The chlorination system appears to be well maintained and tidy. A standby generator is available at the site for use during power failures. Records of pump operating hours, loads, chemical use and treatment parameters are logged. Table M lists the summary of asset data for the WTP and Table M contains detailed asset data for the WTP. The plant schematic is shown on Figure M Table M and Figure M show the data on monthly water quality at Dabose Water Treatment Plant.

109 M31.7 Canacona Water Supply Scheme The Canacona facility consists of a 5 plant commissioned in Raw water is sourced from the Tapona River as well as the Chapoli Dam which came into operation in The river intake has a jack well with 3 pumps (this was locked at the time of visit and therefore we could not assess the condition). The Dam intake pump house was equipped with 3 number 1HP pumps and a small submersible pump (not adequately guarded). The rising main to the plant is approximately 8.5km long. Table M lists the summary of asset data for the WTP and Table M contains detailed asset data for the WTP. The plant schematic is shown on Figure M The raw water pump house and treatment plant are situated in separate compounds. Both compounds were adequately gated, fenced and secured by 24 hour on-site security personnel. The plant is manually operated. The plants operate 24 hours a day, using a three shift system. Measurement of water supplied to and leaving the plant does not occur. The pump house for the dam raw water intake has three pumps (one duty). Each pump has a capacity of 1HP. A small submersible pump is used to augment supplies rather than operating a second large pump. Site maintenance is good, except that the drive couplings/shafts are not guarded. Apart from regular oiling and greasing, maintenance tends to be reactive. No operation and maintenance manuals are available and training for new staff is only provided on the job by existing experienced staff. There are no written or formal safety systems for plant operation. The treatment plant is manually operated. Most equipment appears to be in good working order with the exception of the flash mixer and the clarifier. These two items were not working at the time of the visit. Generally, site maintenance is good. A record of run hours, loads, etc is maintained. Maintenance records are not logged. The plant has a small on-site laboratory and a log is kept of the usual treatment parameters as well as chemical usage. Disinfection is achieved using gas chlorination. Bleaching powder is added manually as a M31-155

110 back-up. The chlorination facilities are not fully contained. Chlorination is achieved using one tonne cylinders. There are usually two cylinders in the chlorination facilities at any one time. There is one vacuum type chlorinator (no standby). Chlorinator maintenance is performed in-house, however the chlorinators are not periodically calibrated and maintenance records are not kept. Spare parts for the chlorination facilities are not kept on-site. Chlorination maintenance, installation methods and operation practices are poor. The only facility to detect or contain gas leaks is an immersion tank. The immersion tank was empty at the time of the site visit. Flexible rubber hose (not copper tubing) is used to connect the cylinders to the chlorinator. This is not a safe practice. A poor quality flexible plastic hose was used as the feeder pipe to the contact tanks. The hose was unprotected. This is not a safe practice and should be rectified immediately. Gas masks are provided (canister type). However, in general, there was a poor understanding and awareness of the safety issues associated with the chlorination process.

122 M31.8 Rural Water Supply Scheme During the Reconnaissance Survey as part of Phase I of this study, the water supply scheme in Canacona taluka was selected and assessed as a representative small scale water supply scheme. The Canacona scheme was selected based on recommendations from PWD staff. There are approximately 4 rural water supply schemes operating in the Canacona taluka and the networks for these schemes are completely independent from each other as well as form the regional scheme. The rural supply scheme at Matve, which supplies water to Parekatta, was visited. The Matve scheme consists of a pump house (manned 24 hours a day) with a small (five HP) submersible pump suspended in a bore well, which is approximately 16m deep. The scheme was commissioned in Bore wells in Goa are constructed by the Central Ground Water Board on behalf of the PHE. The pump feeds a 25m 3 OHR which feeds water to the village under gravity flow. A chlorine solution (5%) is added to the OHR (from 25 litre plastic containers) to maintain residual levels. The study team could not determine whether residual chlorine levels are regularly tested. There is no standby pump which means villagers can go without water for days at a time if the pump breaks down. The study team understood that the scheme supplies a population of approximately 1 people. Water is supplied for approximately two to three hours each day. The supply valves are controlled by PHE staff. There are approximately 25 private connections and 25 public stand posts. There is no charge for water consumed from stand posts in rural or urban areas and consumption is not measured. Table M lists the small scale (rural) water supply schemes in each taluka, which data are mentioned in Sector Status Study WSS Goa, 24. Table M also shows the rural water supply schemes, which are based on the information from PWD during the study period. M31-168
