Consultation process – Examples 2

Understanding development settings The identification of key stakeholders in both Bishkek and Narayanganj was much facilitated by a clear understanding of each city’s groundwater development setting and urban water infrastructure. These were derived from the Urban Groundwater Profile exercise were quite different in each city and it is instructive to contrast them:

Groundwater development setting of Narayanganj: Groundwater provides more than 90% of drinking water supplies in the study area and there is a similar high dependence for industrial and commercial needs. Large-scale groundwater abstraction for public supply and industrial use is mainly from the lower aquifer, and located mainly within the urban area of Narayanganj. Broadly similar designs are employed for public supply and private industrial/commercial use wells alike, so the deeper aquifer horizons are not reserved for potable use. The piped water supply does not extend beyond central Narayanganj, and the per capita supply from the water utility to the urban part of the project area is estimated to average less than 45 l/p/d. Actual per capita usage is therefore almost certain to be widely supplemented with private supplies from either the shallow or (less frequently) the deep aquifer.

While the groundwater productivity in the shallow aquifer is considered too low for large abstractions, it is tapped by numerous narrow diameter boreholes equipped with hand pumps for drinking water and domestic supply purposes. These are locally known as No.6 pumps. The operation of all such bore holes is the responsibility of local user(s) who could comprise just one family or a whole community. The total volume abstracted is unknown but there seems little doubt that the upper aquifer is the primary source of potable supply for the rural and periurban population of the project area as well as a supplement for urban households.

The resultant supply network is therefore diffuse, with piped water-supply coverage within much of urban Narayanganj but numerous handpump-equipped shallow boreholes in rural and periurban districts. A large number of private and industrial wells exist. There is a register but no published estimates exist of abstraction from the lower/main aquifer, and it is very likely that there exist many more unlicensed industrial wells.

There is no modern waste water and sewerage disposal system in the study area and dispersed on-site sanitation is widespread in urban, periurban and rural areas alike. Opportunistic use is made of the storm drainage system in central Narayanganj, mainly for sullage but illegal foul-water connections are said to be common. There is no wastewater treatment plant in the study area. Inadequate drainage results in frequent waterlogging of many parts of the town and this has become a problem.

Groundwater development setting, Bishkek: There is a very extensive piped water infrastructure (pressurised hot water as well as drinking water mains, plus piped sewerage), but widespread on-site sanitation is practised in single/two-story residential areas. Significant amenity irrigation of communal parts of residential areas occurs, using both canalised surface water and pumped groundwater. A highly productive but very localised periurban valley-fill well field located 8 km south of the urban area provides about two-thirds of the city’s water demand, the balance coming from boreholes of various depths distributed throughout the city. These urban wells are screened extensively in the middle aquifer (typically >120 m intake depth), but the lower part of the upper aquifer (40 m-120 m) is also widely tapped.

The majority of abstraction boreholes are operated by the municipal water supply agency, who may provide water for both domestic and industrial processes, and there are also three separate reticulated systems for domestic water. One supplies cold water (domestic potable use), one supplies hot water taps (domestic non-potable use) and one supplies hot water for radiators (non-potable district heating use), the last of which appears to be a closed (non-consumptive) system

which is operated only during the winter. All come under the description ‘public water supply’. The private urban water use categories are less important both in number and volume of water pumped; a small number of factories have private wells, for potable or non-sensitive water supplies and there are also small numbers of private domestic and public municipal irrigation wells. Owner-operated supplies for commercial premises, hospitals and large state administrative buildings appear to be insignificant.

The wastewater disposal system comprises a piped sewerage element, to which industrial, commercial, apartment and public buildings together with some low-rise residential housing are connected, and a dispersed on-site sanitation element in many low-rise residential areas. The relative importance and geographical extent of the latter is not well documented, but may be significant. A wastewater treatment plant receiving domestic and industrial sewered effluent is located on the northern fringes of the city.

City stakeholder features: Thus in Narayanganj:

• Industrial users are important and influential stakeholders, meriting extra effort in consultation;

• There is overlap between rural and urban water supply agencies, especially in the periurban area;

• Users of the shallow aquifer, which still serves as a resource as well as a receptor will be difficult to represent.

• Apart from the water utility (debatable status), no primary stakeholder groups were identified;

The participation matrix in Narayanganj, indicated:

• The pivotal role of the urban water utility WASA and the rural water supply agency DPHE in partnering change,

• The essentially passive role of the Trade associations, who strive principally to safeguard their members’ interests, and

• The potentially negative role of organisations like RAJUK and the Dept of Environment who need to partner implementation of planning or regulatory measures but see little benefit and potential opposition in a control programme.

While in Bishkek:

• State sector agencies remain the predominant stakeholder group members;

• Apart from the utility (debatable status) only secondary stakeholders could be engaged;

• A post-independence depression in industrial activity offers opportunities for context-sensitive planning intervention to support a sound basic infrastructure;

Even though the upper aquifer is not widely used for potable supply, likely high vertical permeabilities, especially in the southern half of the city will favour rapid vertical movement of pollutants towards much deeper aquifers remote from the land surface.

Consultation process – Examples 4

Stakeholder Mobilisation Stakeholders are likely to have very different and possibly conflicting interests in the urban subsurface, stemming from its simultaneous use for the provision of water supply, the elimination of wastewater and the location of engineering infrastucture and buildings (Foster et al, op cit). Once identified, stakeholders were engaged through the medium of a periodic bilingual newsletter (Russian/English, Bangla/English). The aim of this device was

(i) To help establish dialogue

(ii) To set out the key issues and keep stakeholders informed of progress.

In both case-study cities, a one-day workshop was held near the end of the series of newsletters. The final issue recorded the results of the dialogue during the seminar sessions at the workshop. Thus while the technical reports (Morris et al, 2000 and O’Dochartaigh et al, 2000) document the project teams’ conduct of Stage 2 (Situation Analysis) of the groundwater management strategy, the newsletters are the project’s record of tackling Stage 3 (Strategy Definition) of the process. The newsletters trace the course of problem analysis and identification of management targets leading to the development of policy options. Together, the Groundwater Resources Protection/Planning Map (GRPM), and the policy options tables comprise the two parts of a draft Action Plan in each city About half a dozen bilingual newsletters were issued over an 18-month period leading up to a stakeholder workshop in each city. The newsletters were kept short and focused, each edition communicating one aspect of the policy consultation process in a logical sequence leading through:

• Problem recognition;

• Identification of future threats and consequences;

• Setting of remedial/preventive objectives and targets.

• Policy formulation. This process of ‘unpacking’ urban water infrastructure problems and issues gave stakeholders the opportunity to appreciate the diversity of subsurface use and the standpoint of other user groups. The simple analytical tools used are shown for the Narayanaganj case study in Figure 2.

Thus different editions:

• Communicated a synopsis of results from the first part of the project, including the ‘hot-spot’ (potentially contaminating industries on vulnerable aquifer) map;

• Presented Strengths-Weaknesses-Opportunities-Threats (SWOT) analyses of different facets of the city water infrastructure (public and private water supply, wastewater and solid waste disposal, management and regulatory control, planning). This analysis method was employed as it lends itself to brevity in presentation and is likely to be already familiar to some stakeholders from its wide use as a commercial business/market analysis tool (see Figure 3 and an extract in Table 1);

• Provided Problems-Consequences-Targets-Requirements (PCTR) tables for water supply and wastewater/solid waste management. This analysis was intended to bring together public and private uses in such a way as to show the commonality of issues, the resolution of most of which would at some point require either the active participation (or at least the absence of opposition) of private sector users and powerful state industry interests e.g. energy in Bishkek;

• Suggested a range of policy options based on broad strategic objectives (maintaining groundwater supply, safeguarding water quality, sanitary elimination of urban wastewater/solid waste). These were ranked in terms of degree of intervention needed to put the policy into effect (Weak to Moderate to Strong), with an implied link to relative efficacy (Table 2

• Reported the results of the stakeholder workshop, at which each stage of the policy consultation process was revisited and reopened for modification by consensus and where the policy options were debated, revised and/or added to.

Newsletter sets from both cities are provided for reference.
