Water and Sanitation Management Organisation

Installation of Reverse Osmosis (RO) plants under ‘community-managed development of water and

sanitation program for salt pan workers-village community in Gujarat.

SECTION - I : GENERAL INFORMTION AND TECHNICAL SPECIFICATION

1. General Information

1.1. Background

“Food without salt” is like “Life without spirit”

It is truly said that the taste of the food is due to the salt, but many less of us know

that the salt workers takes so much of pain to give the taste to the food. The salt

workers locally known as “Salt Pan (agariyas” reside in coastal belt of Gujarat. Most

of them are migrant workers. Afte r the rains, they migrate to the salt pans where they

work for eight months and return to their native palces during the monsoon. Due to

uncertainties of employment and migration salt pan workers are caught in no -win

situation. It is seen that usually there is no drinking water and sanitation facility

available in their place of work. A majority of the workers live in make -shift hutments

in the salt pans.

We realize the difficulty of working at salt pan, only when we visit that area. Most of

the salt workers were working in scorching sun, had red eyes, dry and black skin,

cuts, burns and blister on their hands and legs. Only shelter was made of jute and

plastic sheet, a small hut, without any facility like electricity, water and so on.

Working conditions on pan and living salt workers are pathetic and yet much has to

be done ameliorate their condition. The category of “salt worker” includes salt

workers on salt pans, the workers working at grinding and packing units as well as

the workers engage in allied activities like loading and un-loading packing salt near

the pan.

In India, salt is produced mainly in Gujarat , Rajsathan, Maharashtra, Tamilnadu and

Andhra Pradesh. Gujarat prduces almost 70 % of the salt in India with ground water

(inland) as well as with seawater (marine land). There are in all 1610 units producing


in Gujarat, which are scattered over 35 talukas of 13 districts in Gujarat. There are

mainly three types of salt production units – below 10 acres plot, 10 acres plot and

more then 100 acres plot. More than 100000 workers are engaged in various

activities of salt industry.

1.2. Drinking water scenario

According to the government rule, the owners of the Salt Pan (agar) should provide

them water, house, road and transport facilities, fuel, tools for salt production

educational and medical facilities, crèche for children Anganwadi etc. but non of

these facilities are made available to them. Only few facilities like houses (sheds

made of wood and plastic sheets), some tools (like spade and large tubs are

provided but not the gloves and gum-boots which protect them from skin problems

during salt production), and irregular water through tankers are provided in some of

the salt pan works by the owners. The drinking water facility provided by the owners

are far-far from satisfaction. The salt commissioner, Govt. of India and the state

water supply department through water supply and sewerage board is trying to look

in to the drinking water problem of salt pan workers in Gujarat State.

1.3. Reform in drinking water and sanitation facility to salt pan workers (Agarias).

For solving the drinking water and sanitation problems for salt pan workers in Gujarat

a program has been developed in consultation and financial support from the salt

commissioner Government of India. Under this program it is proposed to provide

portable drinking water facilities nearer to the salt pans and also sanitary units (toilet)

at each salt pan. This will enable the salt pan workers a hygienic condition and

portable drinking water for the betterment of their health hygiene and efficiency of the

workers and their family members. For drinking water facility, efforts are being made

to provide portable water through long distance pipe line as well as through water

tankers. Under this reform program as last solution the state Government is also

planning to setup Reverse Osmosis (RO) plants at few places, where the

conventional arrangement of providing water through pipe line as well as

through water tankers is not feasible.

For facilitating the community managed water supply and sanitation programme in

the state , Government has entrusted the responsibility to Water and Sanitation

Management Organisation (WASMO).


1.4. Water and Sanitation Management Organization (WASMO)

? WASMO has been established by the Govt. of Gujarat as an autonomous

organization to promote, facilitate and empower Village Panchayats and the rural

community to manage local water resources and have their own water supply

systems and environmental sanitation facilities.

? It empowers the rural community through Pani Samitis (Village Water Sanitation

Committee) having a minimum of one -third women members to plan, approve,

implement, operate and maintain their own water supply systems, manage water

resources and ensure safe and reliable drinking water supply throughout the year.

? WASMO works as a facilitator and provides financial and technical support to Pani

Samitis/ Gram Panchayat and networks with local NGOs, other State Govt.

institution, Govt. of India, donors and UN organization to fulfill the Gujarat Govt.’s

pursuit of strengthening local self-governance through decentralization and

empowerment of the rural community, especially women.

1.5. Programme implementation

The implementation of programme shall be mainly through the respective NGOs

working in the areas. The NGO shall develop a suitable and appropriate drinking

water and sanitation facilities in close consultation with the beneficiaries (Salt Pan

Workers). The NGO shall play a crucial role in implementation of the programme.

1.6. Drinking water sources

The salt workers are normally coming to the pans from the villages near by salt works

locations (Agars ). The ground water in salt workers villages is normally ranging from

2500 mg/l to 6000 mg/l. It is expected that these ground water sources may be

adopted for treatment through RO plants. From these plants the treated water shall

be transported to the salt pan works sites through appropriate arrangement of

transportation suitable to beneficiaries. The ground water at or near salt works pan

sites are highly saline having TDS in the range of 30000 - 50000 mg/l and hence

treatment of these water is not considered.

1.7. Installation of Reverse Osmosis (RO) plants

In view of above, WASMO intends to facilitate the installation of Reverse Osmosis

plants (RO plants) in around 12 villages of the salt work Pan areas of the state. The

plants are to be located in salt work villages where ground water TDS is expected to


be in the range of 2500 – 6000 mg/l. The plants are proposed to meet the minimum

need of water for drinking and cooking primarily. The capacity of the plants in terms

of litres per hour shall be 250 LPH and 500 LPH. The total dissolve solids of raw

water from ground water sources shall be ranging from 2000 to 4000 mg/l and 4000

to 6000 mg/l. The Chlorides shall be in the range of 1000 to 2000 mg/l, in few cases

Fluoride range shall be 1.5 to 3 mg/l and the Nitrate may range from 45 to 250 mg/l

and pH shall range from 6.0 to 8.5. The general raw water chemical characteristics

from ground water sources are given in Annexure-III.

The Total Dissolved Solids (TDS) of product water i.e. desalinated water obtained

from RO plant shall range between 200 and 500 mg/l in any case. The other

chemical parameters of product water shall be within limits mentioned in annexure IV

of this document.

Looking to the raw water characteristic it has been decided to call rates for RO

system for treating two different categories of groundwater quality.

The categories are as under:

Table 1: Categories based on Raw Water Characteristic

Sr. No.

Characteristic Category I Category II

1 TDS in mg/lit 2000 to 4000 4000 to 6000

2 Chlorides in mg/lit 1000 to 2000 1000 to 2000

3 Fluoride mg/lit 1.5 to 3 1.5 to 3

4 Nitrate in mg/lit 45 to 250 45 to 250

5 Hardness as CaCO3 in mg/li 300 to 600 300 to 600

Approximately 12 RO Plants are planned to be set up at 12 locations. These locations are mainly in kutch, Jamnagar, Rajkot and Bharuch Districts. The demand for few RO plants is expected from other coastal districts of the State. The number may increase or decrease by maximum 50%. These plants are expected to be installed within span of Three months. The capacity of plants for which rates are being called is 250 LPH and 500 LPH. The breakup of the capacity and numbers is likely to be as under:


Table 2: Number of RO plants for different Capacities Sr. No.

Capacity of plant in LPH
