Cost Effective & Sustainable Drinking Water Service Delivery: Lessons From Kerala

Dr. V. Kurien Baby

Sr. Programme Officer, IRC – International Water & Sanitation Centre , The Hague, Netherlands

Background

• 2008 April drought period joined as DC• Tanker lorry supply increasing – as strategy at

huge costs • By 2021 Demand supply gap 5900 mcm – IWMI

Kerala Economic scarcity• GoI study on drinking water status and strategy

key findings – shift in investment trajectory• Well based approach – 50% non perennial /quality

–cost effectiveness

Background - Kerala“Water, water, every where, Nor a drop to drink” Samuel Taylor Coleridge

• Kerala has 3000 mm rainfall p.a and 44 rivers• Water Scarcity a recurring phenomena every

summer• Source un-sustainability and quality issues • Highest density of open dug wells in world• 70% of the people still depend of wells for drinking • Investments of Rs. 12000 crore in 45 lakh wells• High access to pipes, poor access to quality water • High household investment as coping strategies

Can we be mute spectators when this water tragedy is taking shape in front of us?

Mazhapolima: Overarching Goal: Health Outcome

Objectives• Provide sustainable access to safe drinking

water thru’ open well recharge (not only pied water – conjunctive provision)

• Recharge ground water- source sustainability– (local action Vs. climate change)

• Improved service level and quality (Sanitized wells – sustainable water campaign)

• Drought mitigation and reduce public spending on tanker supply

• Strengthening decentralization• Pilot test cost effective alternate models

Approach and Strategy

• Community Driven• Participatory approach • Demand Driven• PRI Centric – Govt. department convergence• Facilitatory role for GoK• Process Oriented, Outcome based• Cost Effective – transparency audit• Campaign Mode

Institutional Architecture

Activity Description

Special Gramasabha/Ward sabha

Starts with special grama/ward sabha announcing the message” Our water our future” and ‘wells for welfare’. will conduct the reconnaissance survey/PRA and prepare a water resource atlas /scarcity Map with the inventory of open wells and ponds and prepare the resource map

Preparation of Action Plan and Approval

Ward/GP level

The ward sabha will approve the Action plan comprising the following components: (i) IEC and Awareness campaign: (ii) Training and Capacity Building Plan; (iii) implementation plan: (iv) financing plan and (v) monitoring (quantity and quality) and documentation plan

Implementation Task Force or Jalasuraksha

Samithies

A task Force supported by the resource team will be constituted from among the key stakeholders at the GP level with the mandate of programme implementation.

Block Jalasuraksha

Samithies

Block level Committee will consolidate the block level plan, oversee implementation, coordinate and direct action, poling and leveraging resources and infuse innovative resource mobilization ad integration of ongoing programmes

District Jalasuraksha

Samithies

District Advisory Committee will be chaired by the DP President and DC Vice Chairman with Block presidents and Presidents of the GP Association and selected experts as members and DPO as convener.The Executive Committee will be Chaired by the DC and selected experts, NGOs and key departments as members

Activity Plan – Bottom UP

Technology choice Specification Indicative Cost-Range in Rs

Open well (Drinking)

Roof top harvest with Sand filter*

PVC Gutters are fixed to collect water from roof and water is diverted to the filter using a PVC pipe. The filter consists of sand, metal and charcoal

2500-3750

Roof top harvest with ordinary Nylon filter

Water is harvested from the roof and is diverted to the well through a Nylon or cloth filter using a PVC pipe.

1250-2500

Open wells/Ponds (Non drinking)

Rooftop harvesting with out filter

Water harvested from the roof top is directly fed into the well

500-1000

Surface run off catch Using a bund, trench or pit 500-1000

Rain pits Open pit dug with a specification of 0.75 m x 0.75m x 0.75m

250-500

Backwash with Phyto-remediation

Usually meant for ponds in the lowlands, where a variety of plants and shrubs and trees are planted around the pond to purify water, appropriating the purification properties of plants and trees

2000-4000

(*) Additional Rs. 500 may have to be added for polyethylene sheets for thatched roofs

Capacity Building

Key Performance Indicators

• Substantial cost savings and targets exceeded by 200% in 14 months (T 3000 Ach. >10000 Wells)

• Financial Targets exceeded by 15 times GoK funds of Rs. 10 mn leverage funds Rs 150 mn (GoI 8 mln, GoK 3 mn, Arghyam, UNDP/UNICEF, Pvt. Sector(banks/Edu insts, business)NGOs, CBOs , KWA)

• Source and Quality sustainability ensured (community based quality assurance WQS&M)

• GoK integrated the programme for PRIs/GoI for GWR)• Action Research Outcomes – advocacy/awareness

Recharging Open Wells in the Coastal Riverine Island of (VP)Thuruth improves

water quality

Mazhapolima: Backwash Method -Before and After

Key Outcomes• Reduced morbidity better health (Third party audit)• Reversal of investment trajectory • Polciy Statewide scaling up- 3 districts GO issued• GoK announced Water Security plan (jalasuraksha) for

State• Programme Convergence ( NREGA, watershed, soil conservation, minor

irrigation, PRI plans, GWD programmes)• institutionalized with PRIs – GoK & DPC• National/regional media joined the campaign – National

River Action Framework (hit in India Water Portal)• UNDP /UNICEF (MDG) workshop & exposure visit• State & National award for Adat GP Water Digest Award

2010

Looking towards Future •Watershed river basin approach – building block•Policy integration– GOI treat well as private asset •Area approach for better outcome •Focus on water quality•Integration through NREGA•KILA OR CWRDM LAND WATER MGT CENTRE•Climate change – water-food-livelihood securities and vulnerability reduction – focus well as MUS/marginal holdings
